Flexbiz Server

Flexbiz Server is the backend service for the Flexbiz business application, providing API endpoints for business operations. The current stable version is 12.6.8. It is released on an irregular cadence with breaking changes between major versions. Key differentiators: built for the Flexbiz ecosystem, tightly coupled with the Flexbiz client, and not designed as a general-purpose server framework. Underlying dependencies include Express.js for HTTP handling and Sequelize for ORM, though these may vary by version.
