Optimization goals

One split, computed three different ways.

Pick the goal that matches your contract, and Margin Compass solves for the exact volume split — not just a 0/100 or 50/50 guess.

GOAL — 01

Maximize practice profit

Searches every possible split across all your products — not just the endpoints — for the one that maximizes total blended margin.

Profit-first
GOAL — 02

Maximize contract on one product

Commits exactly enough volume to hit a rebate tier on your priority product, then optimizes the remaining volume for profit.

Contract compliance
GOAL — 03

Optimize originator & biosimilar mix

Holds a minimum share on originator and/or biosimilar products, then maximizes profit within that floor.

Formulary-aware
Data that's actually yours

Real ASP. Your WAC. Your contract.

No fabricated numbers, no black-box pricing — every input is either pulled from a public CMS source or something you supply.

Compliance note. Purchasing and rebate economics must never influence which product is clinically appropriate for an individual patient — product selection stays a clinical decision. Margin Compass only informs which SKU/contract to route volume through once products are clinically interchangeable. Any rebate or discount arrangement should be reviewed by counsel against the Anti-Kickback Statute, Stark Law, and applicable safe harbors before implementation. This is not legal advice. CMS ASP figures are reference data pulled from the published Payment Limit file for the current quarter; verify against the source file before relying on them for a purchasing decision.
