How to track injectable inventory in a med spa
Inventory in an aesthetic clinic behaves nothing like retail stock. Product is consumed in fractions of a container, arrives in lots that expire, and is used inside a documented treatment. Any method that counts boxes will always be wrong.
Short answer
Track injectable inventory at unit level rather than by container. Receive every delivery against its lot number and expiry, deduct units from the treatment record as providers chart, log discarded units with a reason, set par levels and reorder points per location, and reconcile charted usage against counted stock on a fixed schedule.
Count units, not containers
Configure each product with the number of units it contains so a partially used container still reports its remaining units. A count of whole items hides most of your actual position.
Unit-level tracking is also what makes cost per treatment calculable, which is what pricing decisions depend on.
Receive against lot and expiry
Enter each delivery with its lot number and expiry date at the point of receipt. Doing it later, from an invoice, is how lot traceability breaks.
With expiry on file you can act on soon-to-expire stock while it can still be used, rather than discovering it during a stocktake.
Deduct from the chart, never from memory
Usage should come out of the treatment record when a provider charts quantity and lot. One entry, one deduction, no end-of-day stock sheet.
Separate stock logs always drift, because they depend on someone doing a second piece of admin after a full clinic day.
Log waste with a reason
Discarded units should be recorded with quantity, lot and reason. Waste you cannot attribute is waste you cannot reduce.
Reviewing waste by product and by provider usually finds one or two concentrated causes rather than a general problem.
Reconcile on a schedule
Compare charted usage plus logged waste against a physical count monthly. A small, regular variance is manageable; a quarterly surprise is not.
Investigate the variance while the week is still recent enough for people to remember it.
Checklist to take with you

- Lot number and expiry captured at receipt
- Usage deducted from the charted treatment
- Waste logged with quantity, lot and reason
- Par levels and reorder points set per location
- Monthly reconciliation of charted usage against physical count
Common questions
- Why track injectables by unit rather than by vial?
- Because a container is rarely consumed by one client. Unit-level tracking is the only way to know your true stock position mid-week and to calculate product cost per treatment.
- How often should a med spa reconcile stock?
- Monthly suits most clinics, with a spot check on high-value products more frequently. The point is that variances are small enough to explain.
- Does Med Spa Management track lot numbers and expiry?
- Yes. Lots and expiry dates are captured at receipt, selected when a treatment is charted, and retained on the record.
