Self-hostable subscription billing system integrated with Stripe
BillaBear is a standalone subscription management and billing platform with REST API integration, advanced tax handling, workflow automation, and multi-brand support for self-hosted deployments.
BillaBear is a comprehensive subscription management and billing system designed for teams that need full control over their billing infrastructure. Built to integrate seamlessly with Stripe, it provides a REST API for straightforward implementation while offering capabilities that extend far beyond basic payment processing.
The platform handles complex pricing models—from fixed plans and package-based billing to tiered volume and graduated pricing structures. Its tax engine supports country and state-level rules, EU regulations including reverse charge and one-stop-shop compliance, configurable thresholds, and VAT Sense integration for automated rule syncing.
Workflows enable reliable automation of critical business processes with built-in retry logic, eliminating manual intervention when API calls or external services fail. Template management via Twig empowers non-technical teams to modify invoices, quotes, and emails without developer involvement.
BillaBear is self-hostable and extendable, giving engineering teams the flexibility to customize functionality. It integrates with accounting platforms (Xero, EasyBill), email providers (SendGrid, Mailgun, Postmark), help desks (FreshDesk, Zendesk), and marketing tools (Mailchimp, EmailOctopus). The managed cloud version receives continuous updates, while the open-source release follows a six-month feature cycle.
When teams consider BillaBear, these hosted platforms usually appear on the same shortlist.
