VPN Subscription Billing with Auto-Provisioning

This package sets up subscription billing for a VPN provider, on WHMCS or a custom Laravel system, that creates the customer's VPN account when they pay, disables it when an invoice goes overdue and restores it on payment. It is for providers still creating users by hand after each sale and switching people off from a spreadsheet.

How provisioning talks to your backend

The billing side calls whatever controls your VPN users. With FreeRADIUS, the module writes the user to the radcheck table with a Simultaneous-Use attribute, so the server itself enforces the device limit. With WireGuard behind a management API, a key pair is created per device and the peer is added to the right interface. Your own management API works the same way, as long as it can create, disable and enable a user.

• Overdue invoices disable access without deleting anything, so a late payer keeps the same configs.
• Monthly, yearly and multi-year cycles run on Business, with card and crypto gateways.
• Renewal reminders and failed payment emails go out on the schedule you set.

From a single server to several regions

Starter fits a provider with one backend and up to four plans. Business adds server-enforced device limits, longer billing cycles, both gateway types and admin buttons to reset a VPN password or resend login details. Premium connects several backends or regions, handles prorated upgrades and family or team plans with seats, and shows usage figures where your backend records them. A security review closes the Premium build, because this system holds payment state and VPN credentials together.

Choosing WHMCS or Laravel

WHMCS brings invoicing, tax rules and tickets out of the box, and its license is yours to pay. A Laravel build has no license fee and suits app store receipts or unusual plans. Gateways open accounts in your company name and decide approval themselves.
