Start with your chart of accounts. You need at minimum two income accounts: one for Service Revenue and one for Product Sales. In QuickBooks, you can create these as sub-accounts under a parent Revenue account. Service Revenue captures everything clients pay for treatments like facials, massages, body wraps, and similar offerings. Product Sales captures retail items like skincare, haircare, candles, and anything else clients purchase to take home.

The reason this separation matters goes beyond clean books. Product sales and service revenue carry completely different profit margins. A facial might generate 70 to 80 percent margin after accounting for the product used during the treatment and the provider’s pay. A retail skincare product you bought wholesale and resold might only yield 40 to 50 percent. If your total revenue is $30,000 in a month but you don’t know how much came from each stream, you can’t tell whether a revenue increase actually improved your bottom line or just shifted the mix toward lower-margin sales.

Sales tax tracking is another reason to keep these separate. Tennessee applies sales tax to tangible goods, and the treatment of spa services can vary depending on what’s being provided. Having clean separation in your books makes sales tax filings for your spa straightforward instead of a monthly headache.

Your point-of-sale system is where the separation actually begins. Most spa POS platforms like Vagaro, Meevo, or Boulevard let you categorize items as services or products. Make sure those categories map correctly when transactions flow into your accounting software. If your POS dumps everything into one generic “Sales” account, you or your bookkeeper will spend hours every month sorting transactions manually.

For services, consider breaking revenue down further if you offer distinct treatment types. Separate accounts for massage, facials, body treatments, and aesthetic services give you visibility into which lines are growing and which are flat. The same applies to products. Separating skincare retail from other merchandise helps you see what’s actually worth restocking.

Here’s where spa owners often get confused. When a service includes product usage, like the serum applied during a facial, that is not a product sale. The full charge goes to Service Revenue. The product consumed during the treatment is a cost of goods sold or supplies expense. Only retail purchases where the client takes something home count as Product Sales.

If your providers earn different commission rates on services versus retail, accurate separation becomes essential for payroll too. A therapist earning 45 percent commission on services and 10 percent on product sales will have an incorrect paycheck if the two revenue streams are blended together.

Get this structure right, and your monthly financial statements will tell you exactly where your money comes from. You’ll spot trends like retail slowing in certain months or a new treatment generating strong demand. That’s the kind of information that drives real decisions about inventory, staffing, and pricing. If your books are currently lumping everything together, working with a provider of bookkeeping services who understands spa operations can help you restructure and start getting clean, useful data.
