Sell hosting, domains or anything on recurring invoices? WHMCS plus CryptoPayr lets clients clear an invoice in Bitcoin or USDT and marks it paid the moment the chain confirms. Setup is one module and an API key.
WHMCS runs a huge slice of the hosting and web-services world, and a lot of that world's customers would rather pay in crypto than hand over a card — especially the ones buying privacy-minded services in the first place. Adding a "Pay with cryptocurrency" button to your invoices is a small job.
Three things: the CryptoPayr WHMCS module, a WHMCS install on 7.x or 8.x, and an API key from your CryptoPayr dashboard. That's it.
modules/gateways/ directory. It's a standard third-party gateway, so there's nothing exotic about the install.Once it's live, clients see "Pay with cryptocurrency" alongside your other methods on any invoice. They pick it, pay on the hosted checkout in whatever coin they like, and when the chain confirms, the signed callback tells WHMCS to mark the invoice paid and run whatever you've set to happen next — provision the service, fire the receipt, the usual.
Worth being clear about one thing: crypto payments aren't card subscriptions. There's no stored credential to auto-charge next month. For recurring invoices the client pays each one as it's issued, the same way a bank-transfer client would. WHMCS still generates the invoices and reminders on schedule; only the pull is gone.
Two reasons come up again and again. First, chargebacks — hosting is a magnet for them, and a confirmed crypto payment can't be reversed, which takes a whole category of fraud off the table. Second, reach — you can bill a customer anywhere without sweating whether their card clears cross-border. If you've ever lost a sale to a declined international card, you already know the pitch.
Grab the WHMCS module to get started, or skim the docs if you want to see the callback format first.
