P2Flux Payment Gateway For WHMCS

P2Flux Payment Gateway for WHMCS lets your clients pay WHMCS invoices in USDC on Base, sent from their own crypto wallet straight to your wallet in a single transaction. It is a non-custodial USDC payment gateway: P2Flux never holds your money, and you need no merchant account and no API key, only your own wallet address on Base. It is a USDC payment gateway for WHMCS, a WHMCS crypto payment gateway, and a WHMCS stablecoin gateway in one: P2Flux for WHMCS, the WHMCS USDC module for crypto invoice payments, USDC recurring payments, and crypto automatic renewals.

Accept stablecoin payments, crypto payments, and USDC payments in WHMCS with a third-party crypto payment gateway that confirms every payment on the blockchain before the invoice is marked paid. The blockchain transaction hash is recorded as the WHMCS transaction ID, with a link to the block explorer. Use it as your USDC payment gateway, WHMCS crypto payment gateway, and WHMCS stablecoin gateway for the whole invoice payment flow. Every payment, renewal, and refund runs through P2Flux confirmation before it is recorded in WHMCS, so crypto payments in WHMCS work just like any other gateway. It covers the payment flow a crypto client expects, from USDC payments on Base and No-ETH checkout to automatic renewals and full refunds, which makes it a complete USDC recurring payments module for hosting companies, domain resellers, and IT businesses.

Clients can turn on automatic renewals with one wallet approval: P2Flux collects every renewal by itself and WHMCS records each one on the renewal invoice, a true crypto recurring billing and USDC subscription billing flow for WHMCS hosting, domains and addons. The approval can only ever be used for the exact amount and period the client signed. With No-ETH checkout the network fee is paid in USDC, so clients need no ETH for gas. P2Flux notifies WHMCS of every payment and renewal, each confirmed with P2Flux before it is recorded, with the WHMCS cron as the backup, and full refunds are sent from your own wallet and recorded in WHMCS once confirmed.
