What a clinic owner can and cannot plan up front
You can plan structure: which SKUs drive volume, refill cadence, and patient price points your market supports. What you cannot plan up front with Refill is the full COGS line, because medication rates are confirmed at demo and software fees depend on tier. That gap matters most for high-volume GLP-1 programs, where a small per-vial difference plus a percentage transaction fee multiplied across hundreds of monthly refills swings the bottom line. Before margin depends on it, ask for written per-vial cost on your top three SKUs, confirm your software fee percentage, and model total cost including platform subscription.
Also separate provider-network costs if you outsource encounters. Refill publishes hands-on encounters at about $30 and hands-off at about $50 per encounter. Those lines sit outside medication COGS but hit contribution margin on telehealth programs. Build your P&L on all-in landed cost per vial delivered plus any encounter and platform fees, not the headline aggregate medication rate alone.
