Salons deal with two kinds of inventory that need separate tracking. You’ve got retail products on the shelves for clients to buy, and you’ve got professional products you use during services. These flow through your books differently and tracking them the same way creates confusion.

Retail products are straightforward inventory. You buy them at wholesale, sell them at retail, and the difference is your margin. Track these like any retail business would. Record what comes in, record what sells, and reconcile regularly to catch shrinkage or theft.

Professional products are trickier. You use them on clients during color treatments, haircuts, and other services. Some salons treat these as regular expenses when purchased. Others track them as inventory and expense them as used. The right approach depends on how much product you’re carrying and whether usage tracking matters for your pricing decisions.

For retail inventory, use your point-of-sale system if it has inventory features. Most salon software like Square, Vagaro, or Boulevard can track product quantities. When you ring up a sale, the inventory count adjusts automatically. This only works if you’re consistent about scanning products at checkout and recording new stock when it arrives.

QuickBooks Online can handle inventory tracking directly or sync with your POS system. Set up each product as an inventory item with a cost and selling price. When you record a sale, QuickBooks reduces inventory and calculates cost of goods sold automatically. This gives you accurate profit margins on products without manual calculations. Inventory accounting done correctly shows you which product lines actually make money and which ones just take up shelf space.

Physical counts catch what electronic tracking misses. Count your retail products monthly at minimum. High-value items like professional-grade tools or expensive skincare lines might need weekly counts. Compare your physical count to what the system says you should have. Discrepancies point to theft, damage, or tracking errors.

Set reorder points for products you can’t afford to run out of. When inventory drops below a certain level, your system should alert you or generate a purchase order. Running out of your most popular shampoo means lost sales. Overstocking ties up cash in products sitting on shelves.

The bookkeeping side matters more than most salon owners realize. Accurate inventory tracking means accurate cost of goods sold on your financial statements. Guess at inventory values and your profit margins are wrong. Your year-end financials and tax returns depend on knowing what you have on hand.

Shrinkage happens in every salon. Products get used for training, given away as samples, damaged, or stolen. Track these as they happen rather than discovering the loss during physical counts. A shrinkage expense category keeps your books honest and helps you spot patterns that need addressing.

If tracking inventory feels overwhelming or you’re not sure your current system is set up correctly, help is available. A bookkeeper for small business operations like salons can configure your software properly and show you what reports to run. Getting the setup right from the start saves hours of cleanup later.
