How it works
Three steps from invoice to paid.
Customer sees your $Cashtag
On the WHMCS invoice, the module renders a branded Cash App widget with your $tag, the exact amount, and a one-tap open link.
They pay you directly
Payment flows straight into your Cash App — no intermediary, no fees. The customer taps 'I've sent payment' when done.
You verify in one tap
Pending payments hit your phone. Swipe right to mark paid, left to reject — WHMCS is updated instantly via localAPI.
Everything included
Built for real merchants.
Zero payment integration
No Cash App API keys, no monthly fees, no PCI paperwork. Enter your $Cashtag and start accepting today.
Manual verification queue
Every payment cycles Pending → Paid → Rejected. You stay in control of what gets fulfilled.
Domain-locked licensing
Each license is HMAC-signed and pinned to one WHMCS domain. Suspend, revoke, or renew instantly from the admin panel.
Tamper-proof PHP
Ships with SHA-256 integrity manifest. Edit a file, module refuses to load. Prevents customer resale of your code.
Mobile-friendly verification
Verify pending payments from your phone — the WHMCS admin addon is fully responsive, with clear pending / paid / rejected filters.
Branded emails (Resend)
Send license issued / expiring / renewed / suspended notices with fully customizable HTML templates and merge variables.
