Injectables, devices and consumable cost in a medspa
A medspa carries real inventory with real expiry dates, priced in units rather than bottles. Product can be a third of the ticket, which makes the difference between gross and net revenue too large to ignore.
Costing a treatment measured in units
Neurotoxin is bought by the vial and sold by the unit. Filler is bought and sold by the syringe, but partial syringes get discarded. Both mean the cost of a treatment depends on how the product was used, not only on what was bought.
Vial cost $ 620
Units per vial 100
-------
Cost per unit $ 6.20
Treatment, 40 units billed
Product cost 40 x $6.20 $ 248
Wasted / overdraw 3 units $ 19
Injector time (comp structure) ...
-------
Product cost per treatment $ 267
Price charged 40 units x $13 $ 520
Gross margin before injector comp 49%
Run that per treatment type and the picture changes what you promote. Some services carry twice the contribution of others per hour of room time.
Waste, expiry and reconstitution
- Reconstituted product has a limited window. A vial opened for one patient and not fully used is a cost with no revenue attached. Track it.
- Partial syringes. Filler discarded at the end of a treatment is waste that belongs in cost of service, not written off silently.
- Expiry. Product ordered on a promotion and not used before it expires is the most common inventory loss in a medspa.
- Manufacturer rebates and loyalty programmes. These reduce effective product cost, sometimes substantially. If rebates are recorded as other income rather than against cost, treatment margin is understated.
An inventory of "twelve vials" tells you nothing about how many are partially used or how close any of them are to expiry.
Device economics
A laser or body-contouring device is a capital purchase with an ongoing consumable cost, and the two are often quoted separately by the vendor.
| Cost | Where it belongs |
|---|---|
| Purchase or lease | Fixed asset and depreciation, or lease expense. Either way it is a fixed cost per available hour. |
| Consumables — tips, cartridges, gel | Cost of service, per treatment |
| Service contract and calibration | Fixed cost |
| Per-use licence fees, where the vendor charges them | Cost of service, per treatment |
The question to ask before buying is how many treatments a month it takes to cover the fixed cost, and whether that number is credible given the hours you have and the demand you can see. Device purchases fail on utilisation far more often than on price.
Two things to be clear about
Records. A medspa performing medical procedures creates patient records, and those carry privacy obligations that ordinary spa records do not. How you handle protected health information is your obligation to establish with counsel — bookkeeping should be structured so financial records can be kept separate from clinical ones.
Ownership structure. Many states restrict who may own an entity that provides medical services, which is why medspas are frequently structured with a professional entity and a management company. That structure has real accounting consequences — two sets of books, a management services agreement, and intercompany charges that need to be supportable. Get the structure settled with a healthcare attorney in your state before the books are built around it.
Frequently asked
How should we price injectables — per unit or per treatment?
Either works commercially, but cost per unit has to be known regardless. Per-unit pricing is more transparent to the patient and makes waste visible; per-treatment pricing is simpler but can hide a treatment that consistently overdraws.
Where does wasted product go in the books?
Cost of service, in a separate account from product consumed in billed treatments. Keeping it separate is the only way to see whether waste is normal variation or a training problem.
How do manufacturer rebates affect margin?
They reduce effective product cost and should be recorded against cost of service, not as other income. Recorded as income, treatment margin looks worse than it is and pricing decisions get made on the wrong number.
How do we know whether a device is paying for itself?
Divide the monthly fixed cost — lease or depreciation, service contract, financing — by contribution per treatment. That gives the treatments per month needed to break even. Compare it to actual volume, and to the room hours the device consumes.
