Daily P&L for small business: the definitive guide for owner-operators who need to know if today paid for itself.

A daily P&L is a same-day profit-and-loss statement built for the owner-operator standing at the till at close. It takes five inputs from the day — gross revenue, tax, card fees, COGS, variable costs — and one piece of pre-computed configuration (today's slice of the monthly fixed cost stack). The output is today's EBIT, the operating profit your shop actually earned today, visible by 8 p.m. on the same Tuesday it happened. This guide is the long-form treatment: what the genre is, why it is distinct from the monthly P&L your accountant produces and the revenue dashboard your POS shows, the formula and its mechanics line by line, four worked examples across café, retail, salon and Shopify, the diagnostic patterns to look for, the 30-day install plan, and the comparison against the other tools that look like alternatives but are not. By the end you will know how to run a daily P&L for your shop, what to react to in week one versus what to ignore, and how to use the daily number to close a 24-hour feedback loop instead of a 45-day one.

TL;DR

• What it is: a same-day operating profit number, computed every evening from the day's entries.
• What it is not: a replacement for your accountant's monthly P&L, a POS revenue dashboard, or a bookkeeping system.
• Who it is for: the owner-operator who runs the till and needs to know if today paid for itself.
• What it costs in attention: 7–10 minutes once at setup, 60 seconds per evening after.
• What it pays back in margin: typically 2–4 percentage points of EBIT recovered in the first 90 days from catching drift early.

1. What a daily P&L is (and what it is not)

The phrase "daily P&L" sounds like it should mean "monthly P&L, but more often." It does not. Daily P&L is its own genre — a different instrument from the monthly P&L, with different inputs, different precision rules, a different audience, and a different job. It also looks superficially similar to two things it is not: the revenue dashboard on your POS, and the spreadsheet you opened in year two and stopped updating in year three. None of these tools answer the same question. Confusing them is the most common reason owners say "I already have something like this" and end up another quarter behind on margin drift they could have caught.

What a daily P&L IS

A daily P&L is a same-day operating profit number computed for one specific trading day. It runs the same five-line subtraction story as a monthly or annual P&L — gross to net revenue, net minus direct cost to gross profit, gross profit minus operating costs to EBIT — but applied to one day instead of one month. The fixed costs that drip whether or not anyone walked in (rent, salaries, insurance, software, accountant fee) are sliced into a daily portion using the formula monthly fixed total ÷ 30.4375. That slice is applied to today's revenue. What is left after the slice is today's real EBIT — the profit the operation itself earned today, before financing decisions and corporate tax.

The audience is one person: the owner-operator standing at the till at close. The clock is one evening — the number is visible the same day it describes, not the morning after, not next week. The precision is operator-grade — every line traceable to the entries that built it, accurate enough to spot drift inside the working week, not necessarily reconciled to the cent against the accountant's monthly close.

What a daily P&L is NOT

Three things it gets confused with:

• Not the monthly P&L from your accountant. That is a tax-and-audit document built around month-end batch processing. It lands 14–21 days after the month closes and uses statutory categories optimised for filing, not for operations. It is the right tool for VAT returns, year-end accounts and bank financing. It is the wrong tool for deciding whether to change Wednesday's order on Tuesday evening. Daily vs monthly P&L covers this distinction in depth.
• Not a POS revenue dashboard. Your POS shows gross sales by hour, day, week. That is revenue, not profit. It does not subtract VAT, card fees, COGS, variable costs or the daily slice of fixed costs. A POS dashboard that shows €1,247 of Tuesday sales does not tell you whether Tuesday made €297 of EBIT or lost €40. The two numbers can disagree by hundreds of euros a day and the POS will never know.
• Not a spreadsheet. Almost every owner-operator we work with has, at some point, built a profit-tracking spreadsheet. Almost every one of them stopped maintaining it within 90 days. The reasons are structural: spreadsheets do not slice fixed costs daily, do not snapshot COGS, apply card fees to all revenue instead of card-only, and demand 15+ minutes of attention every evening. Daily P&L done well takes under a minute and the rules are mechanical.

Why the distinction matters

If you have one of those three things already and assume you have a daily P&L, you will operate from a flatteringly incomplete signal for years. The POS shows you what the customer paid; daily P&L shows you what stayed. The monthly P&L shows you what the month did; daily P&L shows you what today did, in time to change tomorrow. The spreadsheet you abandoned shows you what you used to track; daily P&L is what gets tracked when the tool removes the friction. Different instruments, different jobs, different precision rules. The next 14 chapters walk through how to build and read one for your shop.

2. The EBIT formula in plain English

Every daily P&L resolves to one number: today's EBIT. Earnings before interest and tax — the operating profit the business itself earned today, before the bank takes interest on any loan and before the corporate tax office takes its slice. For owner-operators of small shops, EBIT is the right daily number because it strips out two things that do not vary day to day (loan interest, corporate tax) and isolates what the operation produced. The EBIT primer is the long-form treatment; this section is the working version you will use every evening.

The formula

Gross revenue (cash + card, including VAT)
  − Tax (VAT or sales tax)
  − Transaction fees (card sales only, never cash)
  = Net revenue
  − COGS (cost of goods sold, snapshotted at the moment of sale)
  − Variable costs (today's small spend across categories)
  − Fixed-cost slice (monthly fixed total ÷ 30.4375)
  = EBIT

Five subtractions. Three lines come straight from today's entries (revenue, variable, COGS). One line is pre-computed from the fixed-cost stack you entered at setup. Two subtractions get missed in almost every spreadsheet attempt: VAT (the customer paid it on behalf of the tax office; it was never yours) and card fees (the processor takes them automatically, but most spreadsheets miss them because the card statement arrives weeks later).

Why divide by 30.4375

30.4375 is the average number of days per month across a year (365.25 ÷ 12). Using it means February days do not carry more rent than March days. Your daily fixed slice stays the same every trading day, which keeps the EBIT signal consistent across short and long months and prevents February from looking falsely heroic. Slicing by "days in this month" (28, 30, 31) produces inconsistent daily numbers that mislead more often than they inform. The 30.4375 rule is small but load-bearing.

Anatomy of an EBIT calculation: the worked example

A specialty café in central Vienna. 14 tables, owner working the bar, one part-time barista on the lunch rush. Tuesday in mild weather, normal trading.

Three things to notice. One: €419 of cost was invisible until the formula surfaced it. €207 in VAT that felt like revenue. €11 in card fees that left silently. €400 of fixed slice that drips every single day whether anyone walked in or not. The till number — €1,247 — felt like a strong day. The EBIT — €297 — is what stayed. Two: the day did not "pay for itself" until the till crossed roughly €700. Below that, the fixed slice alone was not earned. An owner watching only the till crosses €700 at 11 a.m. and assumes Tuesday is in profit by lunch. The reality, on the EBIT formula, is that Tuesday only started building margin after the €700 mark. Three: margin on the day was 28.9% of net revenue. Healthy for a small café (top of the median range; see EBIT margins by sector). The same Tuesday with €900 of revenue — still a busy-feeling day — would have produced about €40 of EBIT. The same Tuesday with €700 would have produced a loss.

3. Gross vs net revenue — why the distinction matters daily

The biggest single error in small-shop profit thinking is treating gross revenue as if it were the business's money. It is not. Gross revenue is what hit the till. Net revenue is what stayed after the tax office and the card processor took their share. The gap between them is typically 18–25% of gross — meaningful money — and the daily P&L surfaces it the first evening you run the close-out. Gross vs net revenue is the dedicated explainer; this section covers the daily implications.

VAT is not yours

When a customer pays €12 for a cocktail at a 20% VAT rate, you earned €10. The other €2 is owed to the tax office on the next return. Treating the full €12 as "your" money inflates revenue, inflates margin and produces a quietly flattering EBIT number. The honest daily P&L extracts VAT first, before any other subtraction, and works in net revenue from that line down. Every "percent of revenue" ratio anywhere in your daily P&L should use net revenue as the denominator, not gross. Using gross as the denominator quietly understates COGS percentage, understates variable cost percentage, and overstates margin — by exactly the share of VAT in your prices.

Card fees on card only

If your processor charges 1.5% and your card mix is 70%, the effective fee on total revenue is roughly 1.05% — not 1.5%. Spreadsheets that apply the card-fee rate to total revenue (including cash) overstate the fee by 30–50% on a typical day. Daily P&L tools worth running separate cash and card at entry time and only multiply the card rate against the card line. The error is small per day (a few euros) and large per year (hundreds, sometimes over a thousand). For high-card-mix verticals like Shopify (where mix is effectively 100% card or Apple Pay routed through Stripe), the rule still holds but the per-transaction fixed component (typically €0.20–€0.30) matters more — on 40 small orders a day, the fixed component alone can be €8–€12.

Net revenue is the denominator for everything below

Once you have net revenue, every cost line downstream — COGS, variable, fixed slice — is computed and expressed against that number. COGS percentage = COGS ÷ net revenue. EBIT margin = EBIT ÷ net revenue. Owners who accidentally use gross as the denominator produce ratio numbers that are 18–25% lower than reality, making the shop look healthier than it is. The mechanical fix is to never look at a "% of revenue" without asking which revenue. The answer is always net.

4. COGS — what it really means and the snapshot mechanic

COGS — cost of goods sold — is the direct cost of the things you actually sold today. Not the things you bought today; the things that left the shop. The milk that went into the cappuccinos. The dresses that walked out of the boutique. The colour that went on a client's hair. For most small shops, COGS is the biggest single cost line on the P&L — typically 26–32% of net revenue for cafés, 40–55% for boutique retail, 8–15% for salons, 30–45% for e-commerce. COGS snapshot explained is the deep dive; this section covers what you need to know to read it on a daily P&L.

Inventory bought ≠ inventory sold

A January where you bought €15,000 of inventory for the spring season is not a January with €15,000 of COGS. Most of that stock is sitting on shelves, unsold. The COGS line on your daily P&L should reflect what was sold today, not what was purchased today. Spreadsheets that record "inventory bought" as "COGS" produce wildly volatile daily numbers — bad days that are really just stock-up days, fantastic days that are really just inventory-running-down days. The fix is to attach cost prices to your products and let the COGS for the day fall out of which products actually sold.

The snapshot mechanic

This is the rule that most spreadsheets get structurally wrong: COGS is snapshotted at the moment of sale. The cost of a cappuccino sold today reflects the milk price you paid this week, not the recipe price from a year ago. If you update the recipe or change supplier tomorrow, today's sale stays at today's cost. Historical entries do not retroactively update when products change.

In nouz this is mechanical. When you sell a product, the system writes the current cost into the sale entry — not a reference to the product. If you update the product's cost price next week, the new cost applies to next week's sales onwards. Last week stays at last week's cost. The daily P&L from any past day is a true historical record.

What healthy COGS ratios look like

These ranges are sector observations across small owner-operator shops in Europe — not gospel. Use them as a sanity check, not a target. A 2-percentage-point drift in the COGS ratio over a month (from 29% to 31%) on €30,000 of net revenue is €600 of lost margin per month — small enough to be invisible in absolute terms, large enough to materially change annual profit. Daily P&L catches that drift the week it starts; monthly P&L catches it three months later, after the drift has already cost €1,800.

5. Fixed vs variable costs

After COGS, the daily P&L splits the remaining costs into two buckets: variable and fixed. The split is not cosmetic — it determines what gets logged daily, what gets pre-configured once, and how the formula slices the fixed stack into a daily portion. Fixed vs variable costs for small shops and what fixed costs actually mean cover the categorisation in depth; this section is the operating version.

The clean test

If the shop closed for a week with no operations, would this cost go to zero? If yes, variable. If no, fixed. A €40 packet of takeaway cups bought on Tuesday is variable — no trading, no cups bought. A €1,800 rent bill arrives on the 1st of each month whether you opened or not — fixed. The test resolves 90% of categorisation questions immediately.

Variable costs — logged daily

Variable costs are the small operational spend that scales with how busy you are: cleaning supplies, packaging, takeaway materials, salon towel laundry, sales-staff commission above base, casual hourly staff above guaranteed hours. Individually each line is small (a few euros, sometimes €40–€60). Collectively they often add 5–8% of net revenue and quietly compress margin if nobody tracks them. The daily P&L expects you to log these as you incur them — usually 0–3 line items per evening, 20 seconds each.

Fixed costs — entered once, sliced daily

Fixed costs are the bills that arrive whether you trade or not: rent, salaries, insurance, software subscriptions, accountant fee, equipment depreciation, the owner's own salary if you pay yourself one. They are entered once at setup with start dates and optional end dates, summed into a monthly total, and sliced into a daily portion using the 30.4375 divisor. From that point on, the daily P&L automatically subtracts today's slice from today's revenue. No manual maths.

The active-window rule

A fixed cost slices into the daily P&L only if today is inside its active window. The rule: start_date ≤ today AND (end_date IS NULL OR end_date ≥ today). A rent contract that started March 1st does not slice into February. A software trial that ended in October does not bleed into November. A salary that began in May does not retroactively burden March. This is the mechanic that lets you add, edit and end fixed costs without rewriting history.

6. Break-even — the floor you have to clear

Once you can read a daily P&L, the next question is: how much revenue does this shop actually need to stop losing money? That is break-even — the revenue level at which total income equals total cost and EBIT is zero. Below break-even, the shop loses money. Above it, the shop builds. Break-even analysis for small business is the full deep dive; this section covers the working version that pairs with daily P&L.

The formula

Break-even revenue = Monthly fixed costs ÷ Contribution margin %
Contribution margin % = (Revenue − Variable costs) ÷ Revenue

A café with €6,000/month of fixed costs and a 65% contribution margin breaks even at €6,000 ÷ 0.65 = €9,231/month. At a €4.20 average ticket, that is 2,198 tickets/month — roughly 73–85 a day depending on trading days. Above that, the café builds. Below it, the café bleeds. Most small shops live within 5–15% of break-even and never know it because they never sat down to compute the number.

Two units to measure in

Break-even is useful in two units. Revenue (euros) is the monthly turnover the shop needs to clear — useful for financial planning, lender conversations, year-on-year comparisons. Units (tickets, customers, orders, services) is the operational version — useful for staffing decisions, the team's daily target, the sticky note next to the till. Most well-run small shops print the daily unit target on a card next to the till or booking screen because "we need four more services today" is actionable in a way "we need €288 more revenue today" is not.

Worked example: Shopify break-even AOV

A small DTC home-goods store. €3,500/month fixed costs (Shopify plan, Klaviyo, part-time VA, warehouse base, accountant, modest owner draw). AOV €55. Variable cost per order: €19.25 COGS + €2.40 packaging + €3.80 fulfilment + €2.10 shipping net of customer-paid + €0.99 card fee + €6.50 blended CAC = €35.04. Contribution per order = €55 − €35.04 = €19.96. Contribution margin = 36%.

Break-even revenue = €3,500 ÷ 0.36 = €9,722/month. At €55 AOV, that is 177 orders/month — about 6 orders/day. Current run rate of 168 orders/month means the store is roughly €500/month under break-even at the current AOV and cost stack. The structural fix is rarely volume (pushing volume usually raises CAC, which lowers contribution margin, which raises break-even further) — it is one of the three classic levers: raise AOV, drop fixed costs, improve contribution margin. The break-even calculator at break-even calculator for small business runs the math live with your own numbers in 30 seconds.

7. Why monthly P&L is not enough

Nothing in this guide argues against monthly P&L. The monthly P&L from your accountant does several real jobs well: tax filing, bank financing, year-end accounts, multi-month trend analysis. It is the right instrument for those jobs and nothing else replaces it. The argument is narrower: monthly P&L is the wrong instrument for running the next two weeks, because it arrives too late, aggregates too coarsely, and uses categories optimised for filing rather than for operations. Daily vs monthly P&L is the full treatment; this section is the working version.

The lag

A typical workflow: April closes Wednesday the 30th. By Friday the 2nd of May, receipts and bank exports reach the bookkeeper. By the 12th the accountant has posted adjustments. By the 14th the April P&L lands in the owner's inbox. The current month is now 45% complete. Any decision the April data would inform — change a price, drop a slow SKU, renegotiate a supplier — applies to June at the earliest. Two-month feedback loop on a business where daily noise is bigger than monthly margin.

What gets lost in aggregation

• Inside-the-month margin drift. A supplier raised wholesale prices on the 5th. Monthly P&L surfaces the COGS bump six weeks later. By then you have sold through 30+ days of stock at the new cost while still pricing as if cost was unchanged. Typically 1–3 percentage points of margin, sometimes more, entirely invisible until the report lands.
• Same-week pattern recognition. Tuesdays do €600. Saturdays do €2,400. On the monthly aggregate, Tuesdays disappear into an average. On a daily P&L with the fixed slice applied, that €600 Tuesday — after €400 of fixed slice and €180 of variable cost — is a €20 loss on the day. Fifty Tuesdays a year, €1,000+ that the monthly average hides.
• Decision-and-test loops. You raise the price of a flat white from €4.20 to €4.40 on the 3rd. On monthly P&L the answer arrives mixed into 41 days of other data on the 14th of the next month. Too aggregated to isolate the test. On a daily P&L the answer is visible by Friday of week one.

Daily vs monthly side by side

8. The 60-second daily close-out ritual

The single biggest objection to daily P&L is the assumption that it means becoming a part-time bookkeeper. It does not. Once setup is complete (7–10 minutes once), the daily close-out is a 60-second routine on phone or laptop. The 60-second daily routine is the long-form walkthrough; this section is the working version.

The one-time setup

Four items, done once:

1. Enter your fixed costs — rent, salaries, insurance, software, accountant fee, your own salary at market rate. Add start dates and optional end dates. Sum into a monthly total.
2. Set your VAT rate (or your country's sales tax equivalent).
3. Set your card processor fee rate (look at your processor statement, find the blended rate).
4. Optionally add your products with cost prices, so COGS is captured automatically at the moment of sale.

Typically 7–10 minutes. After that, never touched again unless a fixed cost changes (new SaaS, salary rise, rent escalation).

The daily ritual

1. Open the app at close. Enter today's gross revenue split by cash and card — the same two numbers you already read off the till tape every evening. 15 seconds.
2. Add any variable expenses paid today — cleaning supplies, packaging, small repair, casual hourly staff. 20 seconds each, usually 0–3 lines.
3. Glance at today's EBIT at the top of the home screen. Compare to yesterday and to the same weekday last week. 5 seconds.
4. If EBIT is unexpectedly low, drill into the line items. Usually one of three: COGS spiked, variable cost spiked, or revenue dipped on a slot you did not expect. 30 seconds to diagnose.
5. Close the app. Tomorrow morning the next day starts. The accountant gets a clean monthly export at month-end.

Total time: 60–90 seconds on a normal evening. Two minutes on a day with an unexpected drop that needs investigation. The setup cost is fixed; the daily marginal cost is roughly a minute. For comparison, the spreadsheet most owners abandoned in year two typically demanded 12–18 minutes a day to maintain — which is why they abandoned it.

9. What to look for in your daily P&L

The daily EBIT number is the headline. But the daily P&L has more signal than just that one number — and learning to read the breakdown is what turns the tool from a curiosity into an instrument. Five things to glance at every evening; three things to do weekly; one thing to do monthly.

Glance daily (5 seconds each)

• Today's EBIT vs the fixed slice. Did today clear the floor? If EBIT is below zero, today did not pay for itself. If EBIT is positive but below your trailing average, something compressed.
• EBIT margin (EBIT ÷ net revenue). The percentage version of the same question. A healthy small shop runs in a 5–10 point band day to day. A 20-point swing is either erratic operations or an entry error.
• COGS percentage vs the trailing 7-day average. The fastest-drifting line. A 2-point spike is worth a quick check; a 4-point spike is worth a phone call to the supplier.
• Card fee percentage vs the trailing 30-day average. Should be flat. If it moves, the processor changed something or your card mix shifted toward higher-rate card types.
• Variable cost vs the trailing 7-day average. A creeping variable cost ratio usually means a small recurring spend has crept back in unnoticed.

Review weekly (5 minutes on Monday morning)

• Day-of-week EBIT. Which weekdays consistently fail to clear their fixed slice? If Tuesdays are losing money four weeks in a row, that is not noise — that is a structural problem with the Tuesday model (hours, staffing, foot traffic).
• Margin by day-of-week. EBIT margin median (not average) for each weekday. Outliers should not drag a weekday's story down; the median is the honest reading.
• Three biggest variable-cost categories. Where did the small spend actually go this week? Often the category that drifted is one nobody was watching.

Sit with monthly (20 minutes on the 1st)

On the 1st of each month, open the monthly aggregate of the daily numbers and the three ratios: gross margin, operating margin (EBIT margin), COGS ratio. Compare to the same month last year if you have it, or to your trailing 4-week average if you do not. Note any ratio that moved more than 1.5 percentage points. Write down one thing to change this month. That is the entire monthly review. How to read a P&L statement covers the deeper monthly review for owners who want the full treatment.

10. Common diagnostic patterns

Once you have 30 days of daily P&L data, certain patterns repeat across owner-operators. Learning to recognise them turns the tool from a number-reader into a diagnostic instrument. Three of the most common — each with the symptom, the cause, and the fix.

Pattern 1: "Sales are up but profit is down"

Symptom: gross revenue is steady or growing, EBIT is flat or shrinking. The owner feels busy, the till is healthy, the bank balance is tight.

Cause: almost always one of three. (1) COGS percentage drifted up because supplier prices rose and menu prices did not. (2) Variable cost percentage crept up because of small recurring spend that nobody categorised. (3) Fixed costs grew faster than revenue — a new hire, a new SaaS, a salary rise — and the daily slice quietly lifted by €15–€30/day, which is €450–€900/month of lost EBIT.

Fix: open the trailing 30 days of daily P&L. Pull COGS percentage, variable percentage, fixed-slice percentage over time. The one that moved up is the leak. Usually the cause is obvious once the percentage is on screen — and the fix is a price rise, a supplier renegotiation, or a SaaS audit. "I make sales but no profit" walks through all seven hidden leaks in detail.

Pattern 2: Prime cost creep

Symptom: for hospitality (café, restaurant, bar), prime cost — COGS + labour as a percentage of net revenue — drifts up over a quarter. February ran 62%, March ran 65%, April ran 68%. Each month feels normal but the trajectory is unmistakable.

Cause: two compounding moves. (1) Supplier price rises that were absorbed instead of passed on. (2) Labour creep — schedule expanded for what looked like a busy season and never contracted when the season ended. Each is small monthly; combined they shift prime cost 3–6 points over two quarters.

Fix: menu price audit (the average European café needs a 5–7% menu price rise every 12–18 months just to hold prime cost flat against supplier inflation) and a schedule review against actual daily traffic patterns. Daily P&L surfaces the drift the month it starts; quarterly P&L surfaces it after the quarter is already lost.

Pattern 3: Margin drift on a steady top line

Symptom: net revenue is flat month over month, EBIT margin drifts down by 0.5–1.0 percentage point per month. The owner feels nothing has changed.

Cause: SaaS creep. The accounting tool that was €40/month is now €60. The new reviews app added €45/month. The Klaviyo tier moved up €20/month. Each individually invisible; collectively, most small shops accumulate €200–€500/month of subscription drift over a 24-month window. On €25,000/month of net revenue, that is 0.8–2.0 percentage points of EBIT margin quietly disappearing into software bills nobody audited.

Fix: quarterly SaaS audit. Open every subscription, ask "did we use this in the last 60 days?", cancel anything where the answer is no. Most shops find €100–€300/month of dead subscriptions on the first pass. The fix takes 45 minutes and pays back forever.

11. Daily P&L vs accounting software vs POS vs spreadsheet

Three categories of tool look like daily P&L alternatives and are not. Each does a real job; none of them does the job daily P&L is built for. Three comparison tables to settle the question.

Daily P&L vs accounting software (QuickBooks, Xero, FreshBooks, Wave)

The two tools coexist. Accounting software runs the compliance layer your accountant needs. Daily P&L runs the operations layer you need. Accounting software vs daily P&L tool covers the comparison in depth, and nouz vs QuickBooks goes specifically into the QuickBooks comparison.

Daily P&L vs POS dashboard

A POS dashboard is a revenue dashboard. Revenue is the top line of a P&L, not the bottom. Two shops with identical till numbers can have wildly different EBIT depending on COGS, variable costs and fixed-cost stack. The POS will show both as €1,247 days; the daily P&L will show one as €297 of EBIT and the other as a loss. Both tools belong on the desk — they answer different questions.

Daily P&L vs spreadsheet

Spreadsheets are the most common attempt at daily P&L and the one most owners have already tried. The reason they get abandoned is not a discipline problem — it is a design problem. The rules a daily P&L needs to apply correctly (snapshot, slicing, active windows, card-on-card) are tedious to maintain by hand. A purpose-built tool applies them mechanically. nouz vs Excel/Google Sheets P&L covers the spreadsheet comparison in detail.

12. Vertical applications: café, retail, salon, e-commerce

The daily P&L formula is the same across every small shop, but the shape of the numbers — what drives EBIT, where the leaks hide, what to watch — varies meaningfully by vertical. A short overview of the four verticals nouz is built for, each with the dominant pattern and a link to the deeper treatment.

Café and coffee shop

What drives EBIT: COGS (milk and bean prices), labour ratio (barista hours vs trading hours), and chair turnover at peak. Healthy EBIT margin: 6–12% median, 15–18% top quartile. What hides: food waste (often 4–8% of COGS, invisible without daily tracking), card-rate drift on a high-card-mix business, and slow weekday losses that the busy weekend hides on a monthly aggregate. What to watch daily: prime cost (COGS + labour) as a percentage of net revenue. A 3-point creep over a quarter is the most common pattern. Why is my café not making money walks through the diagnostic from the loss-side; the break-even calculator runs the cafe-specific math.

Retail boutique

What drives EBIT: COGS percentage (effective blended margin after markdown), foot traffic vs rent, and conversion rate during peak hours. Healthy EBIT margin: 8–15% median, 18–25% top quartile. What hides: dead stock (inventory that quietly sits and never moves, eventually marked down to or below cost), markdown drift (selling more of the season at 30–50% off than the plan assumed), and card fees that scale with the 80–95% card mix retail typically runs. What to watch daily: COGS percentage and the markdown ratio. The retail version of the diagnostic — "my retail store is losing money" — walks through dead stock and the markdown trap that most owners only catch at year-end inventory.

Salon (hair, nail, beauty)

What drives EBIT: chair utilisation (chair-hours sold vs chair-hours available), service mix (high-margin colour vs lower-margin cut), and retail attach rate. Healthy EBIT margin: 10–20% median, 25–30% top quartile — the highest band of the four verticals because COGS is thin and labour is captured as fixed salary rather than variable. What hides: no-show losses on a tight booking calendar, slow weekday gaps that drop utilisation below break-even, and product over-use per service that quietly lifts COGS percentage. What to watch daily: services delivered vs services scheduled, and EBIT margin median by day of week. "My salon is losing money" walks through the utilisation diagnostic in depth.

E-commerce (Shopify and similar)

What drives EBIT: contribution margin per order (AOV minus COGS, packaging, fulfilment, shipping shortfall, card fees and attributed CAC), order volume, and return rate. Healthy EBIT margin: 5–15% median, 18–22% top quartile — the most fragile of the four because contribution margin is structurally lower (many small variable lines stack up per order). What hides: per-transaction card fees on small-AOV orders (a €0.25 fixed component is 1% on a €25 order), shipping shortfall (when customer-paid shipping is less than actual shipping cost), and return processing costs. What to watch daily: contribution margin per order and CAC trend. "My Shopify store is not profitable" covers the e-commerce diagnostic, and the profit margin calculator handles the per-order math.

13. The 30-day plan to install daily P&L discipline

Installing a daily P&L is not a one-evening project — it is a 30-day install with a clear arc. Week one is setup and friction. Week two is the first patterns appearing. Week three is the baseline stabilising. Week four is the first real action. By day 30 the daily close is automatic and the tool is producing usable signal.

Week 1 — Setup and the noisy first entries

1. Day 1: 7–10 minutes of setup. Enter fixed costs (rent, salaries, insurance, software, accountant fee, your own salary at market rate). Set VAT rate. Set card fee rate. Optionally add 5–10 top products with cost prices.
2. Days 2–7: close out every evening. Expect entries to be slightly off the first three days as you learn the workflow — a missed receipt, a misclassified expense, a forgotten cash float adjustment. The number stabilises by day 4–5.
3. What to look at: just today's EBIT. Do not try to read patterns yet. One week of data is not a pattern; it is one reading of each weekday and that is not enough.

Week 2 — First day-of-week pattern

1. Continue the daily close. By end of week 2 you have two readings of each weekday.
2. On Monday morning of week 3, look at the median EBIT by day of week. Which weekdays consistently cleared the fixed slice? Which did not? Do not act yet — the sample is still small.
3. Note any one weekday that looks structurally below break-even. Mark it for further observation.

Week 3 — Baseline stabilises, ratios become readable

1. COGS percentage, variable cost percentage and fixed slice percentage are now stable enough to spot drift. Glance at each daily.
2. On Monday of week 4, do the first 5-minute weekly review. Median EBIT by day of week. Three biggest variable cost categories. Any ratio that moved more than 1 percentage point from week 1 baseline.
3. If a clear day-of-week loss pattern shows up across three weeks of data, this is now a pattern, not noise. Investigate.

Week 4 — First action and the 30-day reading

1. Continue the daily close. By end of week 4 you have four readings of each weekday and a meaningful sample of variable cost categories.
2. Take one action. The most common first actions: cut a SaaS subscription nobody is using, renegotiate a card processor rate, adjust schedule on a consistently loss-making weekday, raise a price on the top-selling product by 3–5%.
3. On day 30, do the first monthly sit-down: 20 minutes with the monthly aggregate. Compute gross margin, EBIT margin, COGS ratio. Write down one thing to change for the next 30 days.

14. How nouz delivers a daily P&L

nouz is a purpose-built daily P&L tool for small-shop owner-operators. Café, restaurant, retail, salon, small e-commerce — the verticals covered in chapter 12. The product is the daily close-out and the home screen that shows today's EBIT. Three things define how nouz delivers it.

Same-day, every day

The product promise is one sentence: did you make a profit today, answered tonight, not next quarter. The home screen of nouz shows today's EBIT — recomputed every time you save an entry — broken down by the five-line formula in chapter 2. By the time you lock the door, today's number is on the screen. Same-day profit and loss covers the philosophy in depth.

Honest fixed-cost allocation

Fixed costs are sliced into daily portions using the monthly-total ÷ 30.4375 formula. Each fixed cost has a start date and an optional end date — past days outside the active window are not affected, future days inside the window automatically inherit the slice. Adding, editing or ending a fixed cost recomputes from that point forward without rewriting history. The three rules — daily slicing, active windows, snapshot on COGS — are mechanical; you cannot turn them off and they cannot be misconfigured into producing flattering numbers.

Built for the owner, not the accountant

nouz is designed for the person standing at the till at 8 p.m. Five-line P&L instead of an 80-line chart of accounts. 60-second close instead of a 15-minute reconciliation. No POS integration to maintain — you enter the two numbers off the till tape, which is faster and more reliable than integrations that break. Monthly subscription, no contract, no per-transaction fee, no tier you have to upgrade out of. Pricing is one number, monthly. Cancel any month.

What nouz does not do: replace your accountant, file your VAT return, run your payroll, manage your inventory, sync with your POS. Those are not the daily P&L's job. The accountant's monthly P&L runs the compliance layer. nouz runs the operations layer. The two coexist without conflict.
