Connect a payment gateway

Connect a payment gateway


Your customers can pay their invoices and quotes with a credit or debit card through the Cin7 Omni payment portal. Cin7 Omni sends the card details to your chosen payment gateway to process the payment.

You can connect to the payment gateways:

Cin7 Omni charges transaction fees and your payment gateway, bank, and other providers may have additional fees. Once you have connected your gateway, you can make paying invoices and quotes easier for your customers by adding payment buttons.
