A salon's books turn on one structural choice — booth rent or commission — and that choice is a math problem. This guide runs the numbers and sets up the tracking both models need.
A salon is two businesses sharing a roof. Services sell time and skill at high margin; retail sells product at a markup and carries inventory. Combined into one income line, retail's product costs quietly inflate the apparent cost of services, and nobody can tell which side of the house is carrying the other. Split them from day one: service income, retail income, product cost of goods, backbar supplies, and labor or booth income each get their own line.
Tips follow the restaurant rule: tips collected for stylists pass through as a liability, never as income. And if stylists are booth renters, they are your tenants, not your employees — rent is your income line, their product is their problem, and mixing the two books helps neither of you.
Weekly capture, monthly close — sized for a business where the owner is also the top stylist.
For a stylist, the comparison is one division. Booth rent is a flat cost; commission is a percentage of gross. The crossover is where rent ÷ commission rate equals monthly gross services. Below the crossover, commission is cheaper (and the salon carries your slow months). Above it, rent is cheaper (and you keep every dollar of growth). Owners run the same math from the other side: a chair under commission earns with the stylist's book; under rent it earns flat — which model wins depends on the chair's realistic gross, not its best month.
A stylist grosses $6,400 a month in services. The salon offers booth rent at $1,100/month or a 45% commission split:
| Model | Math | Stylist keeps |
|---|---|---|
| Commission at 45% | $6,400 × 45% = $2,880 to the salon | $3,520 |
| Booth rent | $1,100 flat to the salon | $5,300 |
| Crossover gross | $1,100 ÷ 45% | ≈ $2,445 / month |
The math is necessary and not sufficient. Before choosing, price the differences the table cannot see:
The Salon and Spa Business Profit Tracker separates service and retail income, tracks product cost and chair economics, and rolls up the monthly margins — in Excel and Google Sheets. If you are a booth renter building your own books, the Freelancer Template covers your income, expenses, and quarterly tax estimate.
Gift card sales are a liability — money owed in future services — not income. Income is recorded when the card is redeemed. Tracking the outstanding balance monthly prevents the classic January surprise of a busy month that produces no cash.
Yes — a booth renter is a self-employed business: their own income and expense records, their own quarterly estimated taxes, and usually their own business license. The salon's books only see the rent.
Retail is typically sold at roughly double wholesale cost before discounts and shrinkage, but your counted margin — from real inventory counts — is the only one that matters. If the counted margin drifts from the expected markup, the gap is shrinkage, discounting, or unrecorded backbar use.
