 ## Support & Sponsorship
 
-**This project is free and open source.** If you find it valuable, consider supporting continued development:
+**This project is free and open source under the MIT License.** The software is fully functional with no features withheld — every user gets the same tool, same collectors, same MCP integration.
+
+However, some organizations have procurement or compliance policies that require a formal vendor relationship, a support agreement, or an invoice on file before software can be deployed to production. If that sounds familiar, two commercial support tiers are available:
+
+| Tier | Annual Cost | What You Get |
+|------|-------------|--------------|
+| **Supported** | $500/year | Email support (2-business-day response), compatibility guarantees for new SQL Server versions, vendor agreement and invoices for compliance, unlimited instances |
+| **Priority** | $2,500/year | Next-business-day email response, quarterly live Q&A sessions, early access to new features, roadmap input, unlimited instances |
+
+Both tiers cover unlimited SQL Server instances. The software itself is identical — commercial support is about the relationship, not a feature gate.
