What a clinic owner can and cannot plan up front
You can plan patient program structure: which SKUs drive volume, expected refill cadence, and the price points your market supports. What you cannot plan up front with a PharmacyLive portal is the COGS number itself, because your compounder controls catalog pricing per deployment. 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 pharmacy rep for written per-vial cost on your top three SKUs and confirm whether the rate is fixed or subject to renegotiation at volume tiers.
Also clarify how ancillary costs hit the P&L. If shipping, cold-chain handling, or payment processing are billed separately from the drug line, the headline per-vial rate understates true landed cost. Build your margin model on the all-in number per vial delivered, not the catalog price alone, so your patient pricing protects the spread you actually need.
