The Medusa.js Architecture Decisions That Matter Before You Build
A practical planning guide for teams deciding how to model products, regions, checkout, and integrations before a Medusa build starts.
By Lyzant

Medusa.js gives teams a flexible commerce foundation, but flexibility creates early architectural choices that should not be treated as implementation details.
The most important decisions usually sit around product modeling, region strategy, pricing rules, checkout boundaries, and how external systems exchange order state.
Strong projects start by documenting the business rules that change often and separating them from the parts of the platform that should stay stable.
Before writing code, map the catalog, payment, shipping, tax, and fulfillment flows in plain language. That makes the build easier to test and safer to evolve.
