Service revenue and retail sales have completely different cost structures and need to be tracked separately. Service revenue is driven by labor. Retail sales involve purchasing physical products, storing them, and reselling at a markup. When both land in one income account, you lose visibility into what’s actually profitable and you can’t make informed decisions about either side of the business.

In QuickBooks Online, create two distinct income accounts. Call them something straightforward like “Service Revenue” and “Retail Product Sales.” Every haircut, color, facial, or treatment gets recorded to Service Revenue. Every bottle of shampoo, styling product, or skincare item sold goes to Retail Product Sales. This split lets your profit and loss statement show each revenue stream on its own line so you can evaluate them independently.

For the retail side, turn on inventory tracking in QBO and set up each product using the Products and Services list. Enter both the cost you pay and the price you charge. When you record a sale, QBO automatically moves the product cost from your Inventory Asset account to Cost of Goods Sold. This gives you accurate gross profit numbers for retail without manual calculations. Retail margins in salons and spas typically fall between 40% and 50%, but you’ll only know your actual margin if you’re tracking cost and revenue separately.

Shrinkage is one of the biggest inventory challenges in salons. Products get used during services when they shouldn’t, staff takes items home, bottles get damaged or expire, and sometimes things just disappear. The only reliable way to catch this is doing physical inventory counts. Monthly is ideal. Compare what QBO says you should have on the shelf to what’s actually there. Record any difference as an inventory adjustment. If your shrinkage numbers keep climbing, that’s a management problem you need to address, not just a bookkeeping entry.

When stylists use retail products during client services, that product cost should be tracked as a service supply expense, not retail COGS. For example, if a stylist opens a bottle of treatment product during an appointment, that cost belongs to your service delivery, not your retail operation. Keeping this distinction clean prevents your retail numbers from looking worse than they actually are.

Your profit and loss should show service revenue with its labor costs and retail sales with its cost of goods sold. This financial clarity is what helps you decide whether to expand your product selection, negotiate better wholesale pricing, or focus on booking more appointments. Without the separation, you’re guessing.

If your books currently have everything lumped together, getting them restructured is worth the effort. A salon and spa bookkeeping service can set up the right chart of accounts, configure inventory tracking in QBO, and build a reporting structure that shows you exactly where your money is coming from and where it’s going.
