Using the payments links is the simplest way to accept payments made with credit card or bank account. This feature is available in the Payrix add-on to pay Invoices and Proforma Invoices. This provides convenience and simplicity for your customers, so the amount of on-time payments will increase. For example, you can add a payment link to the email with the (proforma) invoice. As a result, the customer can make payment quickly by clicking onto such link instead of logging in to their Portal page. In case the customer has saved the payment credentials on the Portal, they do not need to add further details when using the direct payment link in the future. If the credit card in not linked on the Portal, the payment details need to be entered each time the payment link is used.

To create a direct payment link, please use the patterns below:

To pay the Invoice:

by invoice ID

by invoice number

To pay the Proforma Invoice:

by proforma invoice ID

by proforma invoice number
