Will the app keep working after platform updates?

We build on supported APIs and offer maintenance so it keeps working as platforms change.

Do we own the code?

Yes. The code lives in your repository and the app is registered to your account.

Can you connect to our ERP?

Most modern ERPs have APIs. We check yours during discovery.
