Let your clients pay WHMCS invoices with Bitcoin and other crypto.

Plaxswap adds a Pay with Bitcoin & Crypto button to your invoices. The client goes straight to Plaxswap's secure checkout, picks the coin and network they want (with search, for example "usdt trc20"), and sends the exact amount shown, with a QR code. When the payment is confirmed, the money is credited to your Plaxswap merchant wallet and the invoice is marked Paid automatically.

Features

• Pay with BTC, ETH, USDT, USDC, SOL, LTC, TRX, BNB, XRP and more, on the networks your clients use (TRC-20, BEP-20, ERC-20, SPL and others)
• Invoices in more than 60 currencies, including USD, EUR, GBP and INR, with no conversion setting needed
• Automatic payment: a signed webhook marks the invoice paid, and the invoice is also checked when the client returns to it
• Safe by design: the module asks Plaxswap's API for every payment and checks the amount, currency, reference and test/live mode before marking an invoice paid, and records each payment only once
• Pressing the button again within the hour reuses the same payment, so a client is never charged twice for one invoice
• Partial, expired and under-review payments leave the invoice unpaid
• Test mode with a test API key: only a logged-in WHMCS admin can pay, and no real coins move
• Fees and network costs are shown to the client before paying; funds are withdrawn from your Plaxswap merchant dashboard
