Custom Invoice

Dear Sirs,

I have created a new view template for my invoices but I need to put back the functionality for the paid in full or due stamp.

Where can I find the code for the original standard template to get it from there?

Creating new view template removes this and editing directly the original is not allowed.
Please assist.

If you are still using view templates, you need to update your software. They have been replaced by custom themes, which affect all forms, not just invoices. They are much more flexible and powerful. See this release note: [16.11.24] Added ability to create custom themes.

The default theme (the one without any colored bands or background), includes the code for the stamps.
