Did you ever find yourself in a situation where your trusted client with dozens or hundreds of generated invoices and several active services asked for his currency to be changed from one to another?
That and other similar situations can be prevented by using this addon module. This module will make sure your invoices stay untouched even if you change user information or decide to upgrade your PDF template.
The module itself is easy to use and enables you to save user data for each invoice, thus preventing problems in case the user changes his contact data or decides he wants to use some other currency etc.
With this module you can go one step further because it enables you to automatically create and archive every paid invoice in your system. So, even if you change your PDF template, your logo or any of the user contact fields, your WHMCS system will always generate the same PDF file whether it’s getting emailed or downloaded from the client area.
