# CoSuite Developers > Documentation for software vendors who connect their apps to CoSuite (cosuite.io) as module providers using the CoSuite Connect v1 contract, and sell their modules in the CoSuite catalog. CoSuite provides the account, billing, single sign-on and team management; the partner app implements a small set of HMAC-signed endpoints under /api/cosuite/v1 and passes the conformance test (`npx --yes --package=https://cosuite.io/developers/sdk/cosuite-connect-1.8.0.tgz cosuite-connect conformance`). Partners apply and manage their apps at https://partners.cosuite.io. ## Docs - [Getting started](https://cosuite.io/developers/getting-started.md): Connect your software to CoSuite as a module provider.
