WHMCS plugin
Recurring crypto billing in WHMCS.
Add stablecoin payments to WHMCS invoices, client-portal payment actions, and the existing paid-order workflow. Suitable for hosting, SaaS, and managed services already billed through WHMCS.
Existing WHMCS billing cycle
Stablecoin invoices within the existing WHMCS billing cycle
WHMCS already runs your invoices, renewals, suspensions, dunning emails. The plugin slots into all of that — clients pick Paymos at the next invoice, the rest of the flow doesn't change.
Native WHMCS gateway
Paymos appears alongside PayPal and credit card gateways. Clients pick crypto at invoice payment time.
Recurring invoices supported
Renewal invoices generate normally. Clients pay via the same Paymos link each cycle — fresh address per invoice for clean reconciliation.
Auto-marked paid
When the customer pays, the WHMCS invoice is marked paid automatically. Services activate, renewal reminders stop, no manual flag.
Test mode included
Run a sandbox client, generate a test invoice, and watch it confirm. Switch the same connected module to Live when ready.
Install in three steps
From upload to first paid renewal
The plugin ships as a standard WHMCS module. Upload, activate, then approve one Connect Paymos request — no secrets to copy.
Upload the module
Drop the Paymos module folder into modules/gateways. Standard WHMCS install path.
Connect Paymos
Open the intended project in Paymos, then activate the gateway under Setup, Payments, Payment Gateways and click Connect Paymos. Approve the displayed WHMCS URL and current project.
Bill the first client
Generate a test invoice, pay it through the client portal, watch it auto-mark-paid. Switch live, you're billing.
Pricing
