Client Workflow

Credit Cards

Paying with credit or debit card is fairly straightforward for customers. They simply enter in their cardholder information and click Pay. We give receipts to your customers after a successful payment.

Pay Invoice with Credit Card


Customers can pay with ACH just as easily as with credit cards. The key difference is that ACH payments will take several business days to clear. When customers are on a payment form they will select ACH as the payment information and then enter in their bank account and routing number.
