Paymenter, an open source billing and client management panel that turns hosting services into a storefront, recurring invoices and a support desk.
Paymenter is an open source billing and client management platform built for hosting providers and anyone selling recurring services. It gives you a public storefront where customers browse a product catalogue, configure options, place an order and pay, and a client area where they see their services, invoices and payment history in one place. Behind that sits the operator side: an administration panel for products, pricing and currencies, automatic recurring invoicing with reminders and suspension rules, credit handling, coupons and taxes, and a built in ticket desk so customer support lives next to the account it belongs to. Payment gateways and server provisioning are handled by extensions, so the panel can take money through the processor you already use and hand a paid order straight to the system that creates the service. A queue worker and a scheduler run in the background to send invoices, process renewals and act on overdue accounts without anyone clicking anything.
A billing panel is only as trustworthy as the moment it first comes online, so cloudimg closes the window where an unclaimed instance could be taken over. The image ships with no accounts at all: the very first administrator is created on first boot with a random password written to a root only file, so there is no default login to find and nothing to guess in the gap before you sign in. The database password, the application encryption key and the OAuth signing keys are all generated per instance, so no two deployments share a secret. The panel is served over TLS from first boot with a certificate generated for that instance, and the public address it uses is resolved at boot rather than baked in, so links, invoices and payment redirects point at your instance instead of ours. Upstream telemetry is switched off in the shipped image rather than opted in on your behalf. Every deployment ships fully patched, with a paired deploy guide and 24/7 cloudimg support.
