Invoice Auto Login

Invoice Auto Login

Developed By ServerPing

Compatible with WHMCS v8.0

Give your clients easy access to pay invoices!

The Invoice Auto Login addon allows you to include a new merge field in the invoice email templates that will automatically login the user and redirect them to the unpaid invoice. The key used in the URL is a randomly generated hash and automatically expires when the invoice is paid, cancelled or 20 days has passed since the key was generated.


  • Easily allows your customers to pay invoices without having to login using a secure link emailed to them.
  • You can limit access to just the invoice/credit card pages or you can log them into the entire client area.
  • Links automatically expire when paid or if the invoice is cancelled.
  • This module is provided unencoded.

The plugin caused me a lot of trouble. There is no option to exclude clients from the login link. It happened a few times that clients have changed the mail address, but the old login links were still valid and we subsequently got into trouble with the client because colleagues with access to the old account could still log in. A big security risk.

Hi Sean, the login links only work still if the invoice remains unpaid. As soon as the invoice is paid the login links will no longer function and they also expire after 20 days by default but you could also set them to expire after just a couple of days.
