A merchant processor is also called a 'payment gateway'. After integrating a payment gateway with your Invoice Ninja account, your clients will see a "Pay Now" button on their invoices.

What is a Merchant Processor/ "Payment Gateway"

The 'payment gateway' processes your clients payment and your clients never leave their Invoice Ninja client-portal.

The payment gateway then deposits the money into your bank.

You will need to integrate a payment platform with your Invoice Ninja account. There are several free platforms available that you can easily integrate so you can start sending invoices and collecting payments.

Invoice Ninja supports dozens of payment gateways, click here for the full list.
