Automatic Payment Collection (Regular Payments)

Authorize.Net can securely store the member credit card details. This way we can instruct Authorize.NET to make new charges against that card when new invoices are created for the member.

To do this, the member has to pay an invoice using the option “Setup Regular Payments”. If the transaction to pay for this first invoice is successful then the card details of the members are available to pay for new invoices. If, for some reason, the stored card details are no longer valid, the invoice will fail to be paid and a note will be added to that invoice. You can see these notes at the bottom of each invoice.

If this is the case, the member will also receive an email. You can edit the contents of this email from the message template editor. If the member has stored the credit card details you can also request a payment at any point, there is no need to wait for Nexudus to request the payment.

  Important: We never store credit card details in our servers. Although all communications with our servers are encrypted using industry standard methods, we never store your members’ card details and we always rely on the payment providers to do this for us.
