Salon profitability: the complete guide for hair, nail and beauty owners.

Most salon owners can tell you their busiest day of the week and their slowest month of the year. Far fewer can tell you their net margin, their chair utilisation, their average ticket trend, or their retail attach rate. The reason is mechanical, not motivational: those numbers live in five different systems (booking software, till, supplier invoices, payroll, head) and never come together except in a quarterly meeting with an accountant who has already moved on. This guide is the pillar — the single operating manual that ties every salon profitability question into one shape. It uses one worked example throughout (a 3-chair Munich salon at €18,000/month gross), pulls in the eight other salon-specific posts on this site as deep-dives where each topic needs more space, and finishes with a 30-day reset any owner-operator can run between this Saturday and the next. nouz computes the daily version of everything in this post as a side effect of the evening close-out — the math here is the conceptual map of what the app surfaces every night.

TL;DR

1. The salon profitability landscape

Hair, nail and beauty salons sit in an unusual corner of small-business economics. The product is time. The unit of sale is a chair-hour. Inventory cannot be carried forward — a 2pm slot on Tuesday that was not booked is gone forever and cannot be sold tomorrow. The owner is almost always also a working stylist, which means the same person who runs the spreadsheet also runs the colour bowl. Industry rhythm follows local life events (weddings, school holidays, year-end) more than retail seasonality. Cash is high (clients still tip and pay-out at the chair) but margins are thin and hidden behind a few large fixed costs that move slowly.

Net margin benchmarks across the European independent salon market in 2026 sit in a wider band than most owners assume. The honest range, after a market-rate owner salary is included, looks like this:

Two things stand out. The booth-rental house and the high-end colour bar are the only formats that consistently clear 18%+ net. Everything in the middle — the 3-4 chair independent that most owners aspire to run — is the hardest format to make profitable, because it carries the overhead of an employer (payroll taxes, holiday pay, sick pay, training time) without the volume of a chain or the pricing power of a specialist. This is the format that stalls around year 2 most often, and it is the format the worked example in this guide uses, because the lessons there generalise to easier formats as well.

Why year 2 is the killer. Year 1 is the honeymoon: the owner is energetic, the opening rush brings new clients, the lease is fresh, the launch coverage on Instagram pulls bookings. Margin looks fine because the owner is running on adrenaline and not yet paying themselves at market rate. Year 2 is when the lease enters its first review, wholesale supplier costs have moved 6-9% from the opening contract, the second stylist hire needs a step-up, the launch clients have settled into normal frequency, and the owner notices for the first time that they are taking home less than they would as an employed senior stylist somewhere else. Roughly 35-45% of independent European salons close or change ownership between months 18 and 30. The ones that survive made specific decisions about the five levers in this guide; the ones that did not made vague decisions about hard work.

2. The salon revenue math

Salon revenue, stripped of marketing copy, is one equation: chair utilisation × average ticket × productive hours × trading days × number of chairs. Memorise it. Every other revenue conversation in your salon is a derivative of one of those five terms.

Walk through it for the worked example. 3 chairs × 21.7 trading days × 10 hours open = 651 chair-hours theoretically available. At a typical independent utilisation of 55%, that is 358 chair-hours actually billed. Average service duration 70 minutes (1.17 hours). Services delivered ≈ 358 ÷ 1.17 = 306 services/month. Average ticket €58.50. Gross revenue: 306 × €58.50 = €17,901, which rounds to the €18,000 the worked example uses. Each of the five inputs is a lever you can pull; pulling any one of them by 10% moves gross revenue by 10%. The art of running a salon is knowing which lever costs the least to pull next.

The pattern is consistent across thousands of independent salons: the cheapest, lowest-risk 10% always comes from the three free levers (productive hours, utilisation, average ticket). Owners who reach first for "add a chair" or "open Mondays" usually have not exhausted the free ones, and they are buying revenue that costs them margin. The order of operations in any healthy growth plan is utilisation first, ticket second, hours third, chairs last.

Revenue per chair-hour is the unit-economic number that ties this section to the rest of the guide. A salon delivering €40 of revenue per chair-hour is doing fine. €50 is good. €60+ is excellent. The example salon at 358 billed hours and €17,901 of revenue runs €50.00 per chair-hour — comfortably in the "good" zone on the unit metric, but with €18,000 of gross monthly revenue that translates to thin EBIT once the fixed-cost stack lands. The revenue-per-chair-hour number is what nouz tracks on the home screen overnight; the gross monthly number is what gets quoted at parties and tells almost nothing.

3. The service pricing formula

Most independent salons price by what the competitor down the street charges. That is not pricing — that is hoping. The formula that builds every menu price from first principles, in one line:

A 90-minute single-process colour at the worked-example salon: stylist cost €40 (loaded hourly €26.40 × 1.5h), product COGS €18 (colour + developer + toner + towels), overhead allocation €22 (€17.04/chair-hour × 1.5h adjusted for rounding). Total cost €80. Apply 20% target net margin: price = €80 ÷ (1 − 0.20) = €80 ÷ 0.80 = €100. Round to a friendly psychological number: €105. Most European independent salons price this same service at €72-€85. The €20-€30 gap is real EBIT that the salon is leaving on the chair every time the service is delivered.

Three quick disciplines on the formula. First, the divisor is 1 minus margin, not 1 plus margin. A 20% target margin means cost is 80% of price, so price = cost × 1.25. If you mark up cost by 20% you land on a 16.7% margin, not 20%. The most common pricing mistake in the industry is confusing markup with margin. Second, the formula gives you a floor; the market may bear higher. Charge higher when it does — every extra euro above the floor is pure EBIT. Third, every input must be honest: stylist cost includes employer social charges (25-32% on top of gross in DE/AT, up to 50% in FR, 13-15% in UK); product cost includes the half-bottle of toner you eyeballed; overhead includes your own salary at market rate even if the business cannot pay it yet.

For a single-haircut walk-through, how to price a haircut. For the full menu-line treatment across cuts, colour, treatments and add-ons, service pricing for salons. The salon service profitability calculator runs the formula on your own menu in two minutes.

4. Stylist compensation models

Three models dominate the independent salon market: hourly + tips, commission, and chair (booth) rental. A fourth — base + commission hybrid — is increasingly common in mid-sized chains. The choice between them is the single biggest financial decision an owner makes, because it sets cost structure for every chair-hour the stylist will ever deliver.

The hourly model maximises owner upside on busy chairs but requires the owner to keep the chair full — every empty hour is owner-paid labour that returned no revenue. The commission model shifts that risk to the stylist (their pay flexes with bookings) but the owner still carries holiday pay, sick pay, payroll taxes and equipment costs, so the apparent "shared risk" is asymmetric. The booth rental model removes employer responsibilities entirely but caps owner upside — even if the chair generates €2,500/week, the owner still collects only the agreed rent.

The breakeven point between commission and chair rental, for a typical €450/week rent on one chair, lands at roughly €1,800-€2,000/week of chair revenue. Below that, rental usually wins for the owner because labour-as-a-percentage-of-revenue compounds badly on a slow chair. Above that, commission catches up and overtakes because the chair is busy enough that the percentage take exceeds the flat rent. For the full breakeven math with side-by-side P&Ls, see salon chair rental vs commission. The booth rent vs commission calculator takes your specific weekly chair revenue and shows the two outcomes side by side.

5. Chair utilisation — the survivor metric

If you measure only one operational metric in a salon, measure chair utilisation. It is the percentage of available chair-time that gets billed. Denominator: total chair-hours open. Numerator: chair-hours actually invoiced. The gap between the two is the largest hidden leak in the industry, because owners look at whether the book is full of bookings — not at whether those bookings cover the chair.

The worked example: 3 chairs × 10 hours × 21.7 days = 651 chair-hours theoretically available per month. The booking software shows 306 appointments averaging 70 minutes (including blow-dry and tidy time). That is 306 × 70 ÷ 60 = 357 chair-hours actually delivered. Utilisation: 357 ÷ 651 = 54.8%. That sounds bad. It is also entirely typical for European independent salons looking at the number for the first time.

The four reliable causes of chair downtime in an independent salon, in roughly the order they bite: gaps between appointments (8-15% of chair-time), buffer padding into bookings (5-10%), no-shows and late cancellations (3-8%), quiet first-and-last hours (5-10%). Stylist sickness, training and holiday account for another 4-8% annualised. Add them up and the typical leak is 25-45 percentage points — which is why 55% utilisation is the modal number for a salon that has never actively managed it.

Three fixes, in priority order. (1) Eliminate buffer padding: most salons block 90 minutes for services that take 70, "just in case." Tighten to 75 with explicit handoff routines and reclaim 10% of chair-time. (2) Deposit or card-on-file for new clients and same-week appointments — kills the no-show line without scaring regulars. (3) Active rebooking of gaps via a stylist who is paid for it: 20-minute gaps fill if someone owns the responsibility to fill them. Combined, these three moves typically move utilisation from the mid-50s to the mid-60s within a quarter — which on the example salon is roughly €1,800/month of additional gross revenue at zero additional fixed cost.

Two related metrics worth tracking alongside utilisation. Revenue per chair-hour (€50 healthy, €60+ excellent) separates the chair that fills with cheap services from the chair that fills with expensive ones. Revenue per chair spots an underperforming chair specifically — often it is the third chair, added in a growth phase, never properly staffed since. Use the chair utilisation rate calculator for the monthly headline number and the revenue per chair calculator to spot the laggard chair.

6. Product attach — the EBIT lever

A salon sells two things: services and products. Services are chair time you just billed for. Products are the shampoo, conditioner, styling cream, mask and tool the client takes home. The retail attach rate is the percentage of clients who walk out with a product purchase on top of the service. For most independent salons this number sits between 4% and 8%. For coached salons it reaches 15-20%. For top-performing US-style salons it exceeds 25%. The gap matters because retail is, in pure margin terms, the single highest-leverage line a salon sells.

The math on a single product. A €28 take-home shampoo costs the salon roughly €11 wholesale. Gross margin per bottle: €17. That €17 lands in 30 seconds of conversation at the till, with zero chair-time consumed. Compare to a €58 cut that takes 60 chair-minutes and after stylist wage costs roughly €35 to deliver — €23 of contribution margin. The shampoo earns 74% as much contribution as the cut, with 1/120th the time investment. Retail is closer to pure EBIT than any service line in the building.

The fix is behavioural, not technological. Three concrete moves. (1) Stylists recommend take-home product during the service, while the client is in the chair and engaged — not at the till. The pitch is specific and useful: "for the curl shape we just cut, you'll want this for day-three hair." (2) Products are visible and priced. A back-shelf display with no prices kills attach. A countertop display with prices and a small "as used today" card triples it. (3) Attach is coached as a tracked KPI per stylist. Stylists who never see their attach rate measured will not improve. Stylists who see their attach next to their stylist-of-the-month chart will improve quickly. Coaching, scripting and weekly tracking lift the average attach from 5% to 15% within a quarter for most salons that commit to the discipline.

7. No-show policy — what 8% actually costs

Most independent salons run a no-show rate between 5% and 10%. That sounds small and feels small — one missed appointment a day across three chairs. The math says otherwise.

The example salon delivers 306 appointments/month at €58 average ticket. A no-show rate of 8% means 24-25 missed appointments per month, each one a chair-hour-plus that is gone forever. 24 × €58 = €1,392/month of lost revenue, or roughly €16,700/year. At a 40% contribution margin that is €6,680/year of lost EBIT — equivalent to a 4% net margin point on the entire salon. Closing the no-show line from 8% to 2% (the realistic target with a deposit policy enforced) recovers roughly €5,000/year of EBIT with zero new clients, zero new staff, and one written policy.

Three policy options work, in increasing order of friction and effectiveness. (1) A written 50% no-show fee, enforced verbally at booking and printed on the confirmation email, recovers half of one occurrence and deters repeats — typically halves the no-show rate. (2) Card-on-file for new clients and same-week appointments, with explicit consent to charge 50% on no-show, takes the rate to the 3-5% range. (3) Pre-paid deposits (20-30% of service value, redeemable against the booked service) for new clients and high-ticket services takes the rate to 1-3% and self-selects out the lowest-commitment clients. Most well-run independent salons in 2026 are running combinations of (2) and (3).

8. Service mix — short services kill margin

Not all services are equally profitable. A €58 cut and a €58 root touch-up generate the same revenue line at the till but different contribution margins. The cut takes 60 minutes and €1 of product. The touch-up takes 90 minutes and €14 of product. Stylist time is roughly the same per minute. So the cut earns about €36 of contribution margin per chair-hour; the touch-up earns about €15. Multiply across a month where the mix tilts the wrong way and you can lose €500-€800 of margin without any visible change in revenue.

Read the rightmost column. Margin per chair-hour is the only number that matters when deciding which services to push, because the chair is the constrained resource. Express blow-dry and cut win. The full balayage looks like a high-ticket service and is in fact a strong margin-per-hour earner because the price scales with the chair time spent. The root touch-up looks like premium colour work and is actually the worst margin-per-hour in the menu, because the product cost and the chair time are both heavy. The Olaplex add-on wins so hard it has no denominator — it uses zero chair-time because it happens during the colour develop.

A healthy independent salon target mix, expressed as a share of chair-hours (not revenue):

The fix is not to eliminate low-margin services. Some of them anchor client relationships that pay later — a kids' cut on Saturday keeps the parent loyal for ten years of colour. The fix is to know which is which and steer the mix. Three concrete moves: feature high-margin-per-hour services in the menu hierarchy (top of the page, illustrated, "most popular" badge); make low-margin-per-hour services exist but be slightly inconvenient to book (buried in the menu, less prime-time availability); train every stylist to upsell the Olaplex or gloss add-on on every colour service, because it adds €12-€20 of margin with zero additional chair-time.

9. The salon fixed-cost stack

Fixed costs are the lines that do not flex with the number of services delivered this month. Rent stays the same whether you do 50 services or 500. So does insurance, software, accountant, the booking platform, and — non-negotiably — the owner's salary at market rate. The fixed-cost stack is what every contribution margin you earn must climb over before the first euro of EBIT lands.

The honest monthly fixed-cost stack for the example 3-chair Munich salon:

Two reads from this table. First, the fixed-cost stack consumes roughly 75% of gross revenue at this scale — which is why the variable-cost slice (product, card fees, towels) and the contribution margin per service have to do so much work to leave room for EBIT. Second, the owner-salary line at €3,800/month is the single largest discretionary item on the stack, and it is the line most independent salons silently delete to "make the numbers work." Deleting it is what makes the salon look profitable on paper while the owner takes home €1,000/month for 55 hours of work.

Two structural decisions move this stack meaningfully. (1) Lease renegotiation at renewal — a 10-15% rent cut on a salon paying €2,400/month is €240-€360/month of pure EBIT, and most landlords will negotiate before re-marketing. (2) Stylist compensation model — moving from employed to booth rental can cut the stylist + social-charge lines by €4,000-€5,000/month but introduces its own legal and operational complexity (see Section 4 and Section 15). Everything else on the stack moves in smaller increments and is easier to leave alone.

10. Break-even: how many services per month

Break-even is the point where total revenue exactly covers total cost. For a salon, the formula collapses to one line:

The example salon: €13,438 of fixed costs, €58.50 average ticket, ~88% gross margin per service (most independent salons land 85-92% because product cost per service is small as a share of the ticket). Services to break even: €13,438 ÷ (€58.50 × 0.88) = €13,438 ÷ €51.48 = 261 services per month. At 21.7 trading days that is 12 services/day across three chairs, or 4 services per chair per day. The salon today delivers 306 services/month — so it clears break-even by 45 services, which is roughly €2,300 of net contribution toward EBIT and the owner-salary buffer.

Run the formula for your own salon with one number changed at a time. If average ticket rises 10%, break-even services drops by 9%. If retail attach lifts gross margin from 88% to 92% (because retail margin is higher), break-even drops by 4%. If owner salary rises from €3,800 to €4,200 (closer to a true metro market rate for an owner-stylist plus manager), break-even services rises by ~8. The formula is mechanical; the levers are all under your control. Full deep-dive on the four key scenarios (ticket rise, adding a chair, retail attach, owner pays self): how many clients does a salon need to break even.

11. Tiered stylist pricing (junior/senior/master)

Two or three stylist tiers — junior, senior, master — is the standard structure. The temptation is to price the tiers symbolically: junior €45, senior €58, master €70. The math rarely supports that spread, because junior labour cost per service is closer to senior than the rate alone suggests (juniors take longer, partially offsetting the lower hourly).

Labour cost across tiers is almost flat. The price spread should come from the margin target not the cost difference. A defensible tier ladder for a 60-minute women's cut at the example salon:

The master tier carries a higher margin target because clients booking master are less price-sensitive — they are paying for the name, the experience, the specific stylist. The junior tier carries a lower margin because the business goal is conversion: a satisfied junior client who rebooks 3-4 times becomes a senior client, and the senior margin then pays back the junior margin investment. Pricing junior at break-even (or slightly below) for the first 6 months of a new junior's tenure is defensible if and only if you measure the conversion rate to repeat. If it sits below 35%, the junior pricing is subsidising clients who never come back.

Three rules for messaging tiers to clients. (1) Show all three tiers on the menu, always. Clients self-select; you should not have to explain it at the till. (2) Use neutral tier names — "Stylist / Senior Stylist / Master Stylist" or "Level 1 / 2 / 3" — never "junior" on the menu, because clients hear "junior = trainee = bad cut." (3) Never apologise for the senior or master price in conversation. If you signal that you think it is expensive, the client will too. More on tier and service-line pricing.

12. The daily close-out ritual for a salon

The single highest-leverage habit a salon owner can build is a five-minute daily close-out: the moment between locking the door and going home where the day's numbers become the day's knowledge. Most salons do this once a month, late, with an accountant. The best-run salons do it once a day, in five minutes, with their phone.

The minimum close-out captures four things: gross revenue (sum of services + retail + tips), variable cost lines (product used, card fees on card revenue only), today's pro-rated fixed cost slice, and the resulting EBIT. The slightly fuller version also tags revenue by stylist (for tier-level coaching), retail vs services (for attach tracking), and time of day (for utilisation by hour). The whole thing fits on one phone screen. For tips specifically — which are pass-through cash to staff in most jurisdictions and should not inflate EBIT — the help-center article on recording a tip shows how to keep the entry clean.

Three reasons the daily ritual beats the monthly close, even though it surfaces the same numbers. (1) Speed of correction: a quiet Tuesday that does not cover its slice of rent shows up on Tuesday, not on the 15th of the following month. You can move on the data while it is still actionable. (2) Stylist alignment: when EBIT is visible at close, the conversation the next morning shifts from "we were busy yesterday" to "yesterday cleared €87 of EBIT, the gap to target was retail attach." (3) Founder calm: knowing the daily number removes the slow anxiety of "I think this month is going badly, but I won't know until the accountant tells me." Most owners describe the second week of running a daily close as the first time they have ever genuinely known whether they made money today.

13. Diagnosing a struggling salon — 4 leak patterns

When a salon is busy but not profitable, the cause is almost always one of four patterns. The patterns are independent — a salon can be leaking from one, two, three or all four simultaneously — but the diagnosis order is consistent because the fix difficulty rises in roughly this sequence:

1. Chair utilisation below 60%. Booked is not the same as billed. If your gross monthly revenue divided by (chairs × trading days × open hours × average revenue-per-chair-hour) is under 60%, the chair is your leak. Fixes: tighten booking buffers, deposits for new clients, active rebooking of gaps. Difficulty: low. Time-to-impact: 4-6 weeks.
2. Retail attach below 10%. Count tickets that included a retail purchase ÷ total tickets for the last month. If it is under 10%, retail is your leak. Fixes: in-chair recommendation script, visible priced display, weekly attach KPI per stylist. Difficulty: medium (behavioural). Time-to-impact: 6-12 weeks.
3. Service mix too heavy on low-margin-per-hour services. Run every menu line through the pricing formula and sort by margin per chair-hour. If your bottom three services (by margin per chair-hour) account for more than 25% of chair-hours, mix is your leak. Fixes: menu hierarchy, booking-software defaults, stylist coaching on upsells. Difficulty: medium. Time-to-impact: 8-12 weeks.
4. Owner not paid at market rate. Add a €3,500-€4,500/month line for the owner's replacement wage. If EBIT goes negative once that line is on, pricing is your leak. Fixes: a 4-8% price rise on colour, anchored by a new master tier. Difficulty: high (psychological). Time-to-impact: 1 quarter to plan, 2 quarters to fully realise.

In the worked example, all four are open. The full diagnostic with the math on each leak and the order of fixes: salon losing money despite full appointments. The generic seven-leak version covering retail, café and other shop formats: I make sales but no profit.

14. The 30-day profitability reset

If you are an owner-operator reading this guide and recognising more than one of the patterns above, here is the 30-day reset that closes the easiest three leaks in one calendar month. It is sequenced so that each week's work makes the next week's easier.

At the end of the 30 days the typical example salon has lifted EBIT by €1,500-€2,500/month with zero new clients, zero new fixed cost, and no pricing rise to existing services. Leak 4 (owner pay through pricing) is a separate quarterly project: anchor a new master tier, raise colour 8-12% with an email two weeks before, hold cuts flat. Plan in Q2, execute Q3, full impact by Q4.

15. Booth rental vs employed stylists — when each makes sense

The biggest structural decision a salon owner makes after the lease itself is the staffing model. Two distinct businesses live under the same "salon" name: a booth-rental house and an employer salon. They have different cost structures, different cash flow patterns, different legal risk profiles, and different owner roles.

When each makes sense. Booth rental fits when the owner wants predictable, low-volatility income; is prepared to accept capped upside in exchange for capped downside; has the temperament for a hands-off landlord role; can find experienced stylists who already have a client list. Employer fits when the owner wants brand control and consistent client experience; has the appetite for payroll volatility and the cash reserves to bridge slow months; wants to build junior stylists into senior earners; sees the salon as a managed business rather than a property.

A common hybrid that works: 1-2 chairs employed (owner-stylist + one junior on commission), with 1-2 additional chairs booth-rented to experienced self-employed stylists. The owner gets brand control on the employed chairs and predictable rent on the booth chairs. The legal classification on the booth side must be genuinely self-employed — independent client list, own pricing, own hours, own tax registration — or the reclassification risk applies. Full deep-dive on the math, legal frame and the breakeven point between the two models: salon chair rental vs commission. Side-by-side calculator: booth rent vs commission.

16. How nouz delivers a salon's daily P&L

Everything in this guide is math. The discipline is running the math every evening. nouz exists for that — the daily five-minute close that converts the day's till activity into today's EBIT, before you lock the door. The promise is specific: the number lands tonight, on your phone, not weeks later from an accountant.

What nouz does, specifically, that a spreadsheet cannot:

• Snapshots product COGS at the moment of sale. If you change a product cost in the system next month, this month's recorded margins do not retroactively shift. Tuesday's colour margin is the margin Tuesday actually delivered. How COGS snapshots work in nouz.
• Applies card transaction fees to card revenue only. Cash takings are never wrongly deducted a fee they did not incur — a small detail that adds up across thousands of transactions a year.
• Pro-rates fixed costs daily. Rent, insurance, software, owner salary are sliced into a daily figure that updates the moment a new fixed cost is added. You see today's honest EBIT against today's share of the fixed-cost stack, not last month's.
• Allows manual and product-sale revenue entries on the same day. Service revenue from the booking software, walk-in retail tickets, and tip-jar cash all sum into one daily total without forcing you into a single rigid entry method.
• Computes the five-line close in one screen. Gross revenue, card fees, COGS, fixed cost slice, EBIT. One screen, every evening, in under five minutes. No POS integration required — manual entry is the design, because most independent salons run two or three booking platforms and a card terminal that do not speak to each other.

Setup is around seven minutes. Enter your fixed costs once (the table in Section 9 is a good starting template), your VAT rate, your card-processing fee rate, your service menu and current prices. From tonight onward the daily EBIT lands every evening — before and after market-rate owner salary, with retail attach and revenue-per-chair-hour tracked on the same screen. See the salon-specific view of nouz or click around the live demo first. The cross-vertical synthesis of the daily P&L approach lives in the master daily P&L primer, and the distinction between the EBIT margin used in this guide and the bottom-line net margin is in the operating margin vs net margin glossary.

What to do this week

Five concrete steps from this guide that any owner-operator can run between this Saturday and the next. Total time investment: 60-90 minutes.

1. Pull last month of booking-software data and compute chair utilisation: chair-hours billed ÷ chair-hours available. If you are under 65%, leak 1 is open. Use the chair utilisation calculator if you want the math done for you.
2. Pull last month of till data and compute retail attach: tickets with retail ÷ total tickets. If under 12%, leak 2 is open and is probably the largest single uplift in pure margin terms.
3. Run every menu line through the pricing formula. Use the salon service profitability calculator. Sort by margin per chair-hour. Identify the bottom three lines. Decide: reprice, deprioritise, or quietly retire.
4. Add a market-rate owner salary line to your P&L (€3,500-€4,500/month for a working owner-stylist in a European metro). Check whether EBIT stays positive after the line is included. If not, leak 4 is open and requires a pricing decision.
5. Start the daily five-line close-out tonight. Gross revenue, card fees, COGS, today's fixed cost slice, today's EBIT. Use the daily profit calculator for the first week to build the habit, then switch to nouz for the recurring discipline.

The shortcut: setup takes about seven minutes. Enter your fixed costs, your VAT, your card fee, your service menu, your starting prices. From tonight onward your daily EBIT lands every evening — before-and-after owner-pay, with utilisation, attach and revenue-per-chair-hour tracked over time. The help-center first-week checklist covers what to do in the seven days after the first close-out lands. Same-day profit and loss is the core promise; this guide is the operating manual that makes the daily number actionable for salon owners specifically.
