In case any Invoice Suppression is in use, this page provides additional details for each suppressed invoice. Each transaction can be expanded on click. This will show a sort of preview of what's inside PDF files. Lastly don't forget that there's an option automatically adds the URL to this page to clientarea navbar.
Almost every WHMCS has a sidebar that shows credit balance to logged customers. Showing credit balance is pretty simple job but Billing Extension is a step ahead and adds a feature that your customers will surely love. Let's see what happens when you enable Low Credit Notification.
This check repeats every time an invoice is paid with credit (full or partial) still based on the same period which in our example is 30 days. Renewal costs are based on domains, products/services and addons that expire between current date and the given number of days. In order not to annoy customers with unnecessary emails, we make sure that each customer receives a maximum of one "Low Credit Balance" notification per day.
