Custom Billing System

This package builds a complete recurring billing system for a service, hosting, agency or subscription business that has outgrown spreadsheets or a billing tool it keeps working around: clients, products and price plans, recurring and one-off invoices, online payments, reminder emails, a client portal and a Filament admin for your staff. It is broader than a simple invoicing portal, because it runs the whole billing cycle on its own, and different from a Stripe Billing setup, because the billing rules live in your system and the gateway only takes the money.

What runs every night

A scheduled job finds every service due for renewal, raises the invoice with the right price, discounts and tax, emails it, and attempts the charge on the saved payment method. Paid invoices mark the service as active until the next due date; unpaid ones move into your reminder sequence. Invoice numbers are sequential and never reused, and a sent invoice is corrected with a credit note rather than edited.

• Cards are entered in the gateway's hosted fields, so your database holds tokens and the last four digits, never full card numbers.
• Business adds proration, so an upgrade halfway through a month charges only the difference.
• Premium sends webhooks or API calls when a service is paid, suspended or cancelled, so your control panel or app can act on it.

Custom build or WHMCS?

If you sell standard hosting, domains and licenses, WHMCS plus a few modules is usually cheaper, and I will tell you that before you order. A custom system makes sense when your products, contracts or approval steps do not fit WHMCS without heavy patching, or when you want no per-client license at all. More on that trade-off is on the WHMCS services page.

Not part of this build

Gateway and merchant account fees, hosting and your domain are paid to those providers in your name. Tax rates come from your accountant; I set them up, I do not decide them.
