Side by side

What it does

A self-hosted billing and storefront for hosting companies, handling products, invoices, Stripe and PayPal payments and provisioning through Pterodactyl and other panels.

A merchant-of-record billing platform for selling subscriptions, digital products and usage-based plans, handling payments and sales tax.

Watch out

Smaller ecosystem of provisioning extensions than WHMCS.

Merchant-of-record means a percentage fee on each sale, and the hosted service is the real product even though the code is open.
