Blesta

Blesta is a billing and client management platform designed for hosting providers, domain registrars, and other subscription-based businesses. It positions itself as a modern alternative to WHMCS with a cleaner codebase and more flexible architecture.

The platform handles client registration, invoicing, payment processing, automated provisioning, support tickets, and domain management. It supports a wide range of payment gateways including PayPal, Stripe, Authorize.Net, and many others. Recurring billing, late payment automation, and tax handling are all built in.

Blesta's module system allows integration with cPanel, Plesk, DirectAdmin, Virtualizor, SolusIO, and dozens of other hosting platforms. Provisioning modules automate the creation and management of hosting accounts, VPS instances, and dedicated servers based on purchased plans.

What sets Blesta apart is its developer-friendly design. The codebase follows proper MVC patterns, uses Minphp as its underlying framework, and provides clean APIs for extension development. The plugin system is well-documented and easier to work with than WHMCS hooks.

Blesta uses a one-time license fee rather than a monthly subscription, which appeals to providers who prefer to avoid ongoing software costs. Updates are included for one year with the option to renew.
