bxb_
The complete billing solution. A flexible API for the full billing lifecycle — invoicing, subscriptions, payment methods, wallets, usage metering, and customer management.
Use the API directly to power custom frontend or mobile app billing flows, or combine it with bxb-elements for a ready-to-use customer billing portal within minutes.
