Inventory may not feel like the most exciting part of running a med spa, but Rebekah and Janelle make the case that it is one of the most important. When inventory is not managed properly, it does not just create operational headaches. It directly affects revenue, profit, patient experience, and team trust.

For this discussion, they focus on consumables tied to services and sales, including neurotoxins, fillers, retail products, laser tips, and other items with a cost attached. These are not just supplies sitting on a shelf. They are dollars already spent by the business, and if they expire, disappear, get mismanaged, or sit unused, that money is never recovered.

Janelle explains that a healthy inventory system starts with knowing run rates and par levels. Practices should understand how quickly they move through each product and avoid sitting on too much, especially with injectables. Turnaround times are often quick, and provider preferences, vendor trainings, seasonality, and new product excitement can all create artificial spikes.

Rebekah adds that practices should be careful not to bring on a new product just because a vendor created excitement around it. If existing product is still sitting on the shelf, that inventory needs a plan before more money is spent. Otherwise, practices can end up with potential revenue sitting unused until it expires or has to be pushed through last-minute promotions.

They also talk about the risk of understocking. When a patient comes in ready to repurchase a retail product and it is not available, the practice may lose the sale completely. Even when the item can be ordered or shipped later, it adds friction to the patient experience and creates more work for the team.

The strongest operational takeaway is around tracking. Filler should always match. Neurotoxin may have a small acceptable shrinkage range, but anything beyond that should be investigated. Communication slips, daily counts, locked product, management sign-offs, and double-checking tickets may sound intense, but they protect the business and the team.

These systems are not about mistrusting staff. They are about preventing human error, protecting provider pay, improving ticket accuracy, and making sure revenue does not silently leak out of the practice. Inventory is a controllable cost, and when practices manage it with discipline, they protect both the top line and the bottom line.
