Frequently Asked Questions
How do you prevent an enterprise customer from losing access during a 30-day invoice payment window?
We decouple subscription entitlement status from immediate charge collection on `send_invoice` subscriptions—granting active seat entitlements upon contract signature while enforcing automated dunning/grace-period workflows past the net-30 due date.
