Is it worth staying open on slow days? The contribution-margin test
Staying open on a slow day is worth it as long as the day’s revenue covers its avoidable costs — the staff, stock and fees you’d save by closing — because your rent and insurance are already paid whether you open or not. The test isn’t whether a slow day turns a full profit; it’s whether it clears its variable costs and puts anything at all toward the fixed costs you owe regardless. Here’s the exact math, a worked example, and the move most owners miss: not closing, but opening lean.

The free salon daily P&L template (5 lines, 90 seconds, every night at close)
A salon daily P&L is not a shrunk-down monthly one — it is five lines you fill in at close: service revenue split cash and card, retail revenue, tips paid through, any product or supply cost that landed today, and today's EBIT. Ninety seconds standing at the desk after the last client leaves. This is the daily template that feeds the monthly one, and the reason you know whether Tuesday actually paid before you lock the door — not three weeks later when the accountant's report arrives.

How to calculate COGS for a cafe: formula, example, and the % to aim for
Cafe COGS = opening inventory + purchases − closing inventory — the cost of what you actually sold, not what you bought. Here is the formula, a worked monthly example, the healthy 28-35% band, and how to track it without a Sunday spreadsheet.

How often should you check your P&L? A cadence, not a number
Check your P&L on a cadence, not a schedule: daily for the numbers, weekly for the trend, monthly for the structure, quarterly for the big calls. Here is what to look at at each interval, how long each takes, and why a monthly-only report from your accountant is too late to run a shop on.

Shopify profitability: the complete guide to running a DTC store that actually pays you
Most Shopify stores do not lose money because the product is bad. They lose money because the cost stack is invisible until month-end, the platform dashboard reports gross as if it were profit, and the owner is making spending decisions against a number that does not tie to the bank. This is the full pillar — net margin benchmarks by category, the true cost stack, per-order math, AOV vs CAC vs CLV, attribution honesty, return-rate accounting, shipping economics, discount damage, the daily close-out, and the 30-day reset that turns a struggling store profitable. Built on the same EBIT formula nouz uses every evening.

Cafe profitability: the complete operating guide for owner-operators in 2026
Is opening a cafe profitable? Yes — narrowly. Most independent cafes clear a 5-12% EBIT margin, the top quartile lands 13-18%, and roughly 30% close inside year one. The difference is rarely talent or location; it is whether the owner runs the cafe on a daily P&L or a quarterly accountant report. This guide is the complete operating manual: the formulas, the benchmarks, the menu engineering, the diagnostic patterns and the 30-day reset — written for the owner who runs the till, not their accountant.

The salon service pricing formula: stop guessing, start building prices
Most salon owners price by what the competitor down the street charges. That is not pricing — that is hoping. This is the formula that builds every menu price from the four costs underneath it, with worked numbers, a 90-minute colour example, and the eight signals that say it is time to raise.

Return on ad spend mastery: what ROAS actually means, what good looks like, and why most owners chase the wrong number
ROAS is the most-googled DTC metric for a reason — it is the simplest acquisition number to compute and the easiest to misuse. A 4x ROAS sounds good until you realise your gross margin is 30% and you needed 3.33x just to break even. This is the full ROAS guide: the formula, the break-even math, the eight worked thresholds by margin, ROAS vs MER vs PROAS, the iOS 14.5 break, channel benchmarks, and the daily reconciliation against your bank.

Open-to-buy formula: the merchant-planning playbook for independent boutiques
Open-to-buy (OTB) is the planning tool that tells you exactly how much new stock you can purchase in any given month without choking on inventory. Big-box retailers run it as religion.

The attribution window myth: why Meta says 8x ROAS while your bank account stays flat
Meta says you got 8.4x ROAS this week. Your bank shows you broke even. Both are accurate; only one is useful. Here is what attribution windows actually do, the five ways they overstate ad performance, the 14-day pause test that exposes the truth, and the single math that does not lie.
