What a clinic owner can and cannot plan up front
You can plan the structure: which SKUs drive volume, expected refill cadence, and the patient price points your market supports. What you cannot plan up front with Tailor Made Compounding is the COGS number itself, because per-vial rates are not public. That gap matters most for high-volume GLP-1 programs, where a small per-vial difference multiplied across hundreds of monthly refills swings the bottom line. Before margin depends on it, ask your account manager for written per-vial cost on your top three SKUs and confirm whether the rate is fixed or subject to change at renewal.
Also clarify how ancillary costs hit the P&L. Tailor Made ships via UPS only and bills as a cash-based pharmacy. If shipping, signature delivery, or card processing are billed separately from the drug rate, the quoted per-vial number understates true landed cost. Build your margin model on the all-in number per vial delivered, not the headline rate.
