Cash App Payment Gateway for WHMCS
Add Cash App as a payment method on WHMCS invoices, with payments matched to invoices and a log of every transaction for your records.
What does the Cash App gateway do?
It adds Cash App to the payment methods on your WHMCS checkout and on unpaid invoices. A customer who picks it gets a payment request, which is also sent by email so the payment step is not lost if they close the browser. When the payment comes in, the module checks it and applies it to the invoice it belongs to. WHMCS then marks that invoice paid and runs any provisioning tied to it, so a new order does not sit waiting for someone on your team.
Not every payment lines up neatly. When the module cannot match one automatically, it stays in the transaction log for an admin to reconcile by hand, so nothing is applied to the wrong invoice on a guess.

| Checkout | Cash App offered at checkout and on unpaid invoices |

Who is it for?
WHMCS businesses that sell mostly to customers in the United States, where many people would rather pay from Cash App than type in a card number. That covers hosting companies, web agencies and freelancers billing for service plans. I recommend running it next to a card gateway rather than in place of one. WHMCS lets each customer choose from the gateways you enable, so adding Cash App changes nothing for people who already pay by card.
Before going live, add a line about Cash App to your invoice email so customers know the option is there, pay a small test invoice yourself, including one manual reconciliation, and decide which staff member clears unmatched payments. Because every payment is in the log, your team can answer "did my payment go through?" without opening the Cash App account.
What do you need, and what are the limits?
Requirements: WHMCS 8.x (I confirm the exact version with you at purchase), PHP 8.1 or newer, and a Cash App account that can receive payments from your customers.
Limits: Cash App decides which account types and countries it serves, so check that your business account can accept payments from your customers before you buy. Fees, payouts and disputes stay between you and Cash App. The module connects WHMCS to your Cash App payments and does not hold any funds itself.
It costs $39 once for a lifetime license with twelve months of updates and support, an instant download and license key, and a seven-day refund window.

Frequently asked questions
Can customers pay WHMCS invoices with Cash App?
<p>Yes. The module adds Cash App as a payment method at checkout and on unpaid invoices, and each payment request is also sent by email. Once a payment is checked and matched, it is applied to the invoice and WHMCS marks it paid and runs any provisioning linked to it.</p>
What happens when a Cash App payment does not match an invoice?
<p>It is not applied on a guess. The payment stays in the transaction log, and an admin reconciles it by hand against the right invoice. Most payments match automatically; manual reconciliation is there for the ones that need a person to decide.</p>
Can I offer Cash App alongside card payments?
<p>Yes, and I recommend it. WHMCS supports several active gateways at once, so customers choose Cash App or your card gateway on each invoice. Customers who already pay by card see no change.</p>
