Do you have to make manual adjustments to the service/invoice dates whenever a user doesn’t pay his invoice right away?
This addon module will enable you to skip all that, because the Fix due date addon module automatically detects those situations and fixes the dates, not only for the service/domain but on the invoices also!
If some user makes an order od December 1st and pays the invoice on December 5th, why should he have 4 days stripped away from him, or why should you have to manually correct the dates on the service details page and on the invoice?
Using the Fixed due dates module will make your life much easier as it also detects suspended accounts! Now, if the payment is a few days late, user gets his service reactivated with a new date and the invoice with corrected dates.
Be fair to your users and forget about manual corrections for late pending order activations and late renewal payments!
