Paymenter

Paymenter is an open-source, self-hosted billing and subscription management platform designed for hosting companies and similar operators. It provides an admin UI, customer portal, REST API, invoicing, webhook handling, and a marketplace for extensions — all intended to replace custom billing code or a hosted billing SaaS.

The tool targets teams that want full control over payment data and billing workflows while retaining the ability to customize and integrate deeply with provisioning and accounting systems. It is implemented as a PHP application (PHP 8.2+, Composer) and expects a typical LAMP/LNMP stack and MariaDB.

Use Cases

• Hosting providers who need products, plans, and lifecycle hooks to provision infrastructure automatically when customers subscribe.
• Small-to-medium SaaS teams that want a self-hosted billing system to avoid vendor lock-in and keep customer/payment data on-premises.
• Operations or devops teams that can maintain PHP-based applications and want an API-driven billing backend to integrate with CRM, accounting, or provisioning systems.
• Organizations that already use Stripe and want a faster path to accept payments via an official integration and webhook handling.

Strengths

• Self-hosted: full control over data, code, and customization; you can inspect and modify the source.
• Billing and subscription lifecycle: recurring plans, one-time invoices, and standard subscription operations (create/cancel/suspend/renew) out of the box.
• Stripe-first integration: official Stripe integration and webhook support for quick time-to-payment processing.
• Admin panel and customer portal: reduces the need to build separate interfaces for administrators and customers.
• REST API and CLI utilities: supports automation, CI/CD installs, and integration with provisioning or accounting pipelines.
• Marketplace and extensions: community-driven plugins make it easier to add features over time.
• Documentation and security focus: official docs, guides, and an emphasis on secure payment handling reduce onboarding friction for self-hosters.

Limitations

• Smaller community and ecosystem compared with established commercial billing platforms; fewer off-the-shelf plugins and less third-party troubleshooting content.
• Operational overhead: you must manage PHP, webserver, database, backups, security patches, and upgrades — it is not a zero-maintenance SaaS.
• Primarily Stripe-focused: non-Stripe gateways may require community plugins or custom development.
• Opinionated platform support: documentation targets Linux distributions and common LAMP/LNMP stacks; Windows is not a supported host.
• Documentation gaps for edge cases: some scenarios may require reading source code or engaging the project on GitHub for fixes and workarounds.

Final Thoughts

Paymenter is a practical choice when you need an open-source, self-hosted billing system tailored to hosting workflows and you have the ops capacity to run and secure a PHP application. Its Stripe integration, admin UI, API, and extension marketplace make it a good fit for hosters and SMB SaaS teams that value control and customization.

Choose Paymenter if you can commit to ongoing maintenance (patches, backups, upgrades) and either already use Stripe or can invest in gateway integrations. If you prefer a turnkey, hosted billing solution with minimal ops responsibility or require broad, built-in gateway support immediately, a managed SaaS billing product will likely be a better fit.
