How should injectables be handled in my books?

When you buy Botox, filler, or any other injectable, that purchase is inventory. It sits on your balance sheet as an asset until you use it on a client. Only when units are actually used does the cost move to your profit and loss statement. This distinction determines whether your financials tell you the truth about your business.

Most med spa owners expense injectables when they buy them. A $3,000 order hits the expense account in January, even though those units might last through March. January’s P&L looks terrible, February looks artificially good because no product was purchased, and by March you have no idea what your actual margins are. You’re measuring spending, not the cost of what you delivered.

The right approach tracks units. When a shipment arrives, you record it as inventory on the balance sheet. When you use 20 units on a client, those 20 units move from inventory to cost of goods sold. At the end of the month, your books show exactly how much product you used, and that cost matches the treatments you billed. A CPA for medical businesses can set this up so it runs smoothly month to month.

This requires knowing what you actually have on hand. Physical counts, at least monthly, need to be reconciled against what the books say you should have. If the books show 150 units of Botox but the shelf has 130, the difference is waste, theft, expired product, or documentation error. Without the count, you never know. With it, you can investigate and fix the problem before it gets worse.

Expired product deserves its own tracking. Injectables have shelf lives, and units that expire before use are a real cost. Recording them as a shrinkage expense rather than hiding them in general product cost shows you exactly how much you’re losing to expiration. That visibility is how you improve purchasing decisions and reduce waste over time.

The payoff is margin clarity. When you know the actual product cost per treatment, you know which services make money and which ones don’t. A treatment that looks profitable at list price might be a loser once you account for the units actually used, especially if your providers are inconsistent with dosing. Proper inventory and cost tracking surfaces those problems before they drain your profits.

Most accounting software handles this, but it has to be set up correctly and maintained consistently. If your injectables are currently just hitting an expense account when you order, your financials are not giving you the full picture.
