XtekTrev,
What do you mean by customer facing documentation? Do you mean the printed Invoice and Estimates? For that you can use the Report Designer to create a custom Invoice/Estimate templtea. You can make a copy of the stock one and add/remove the fields you want on the invoice/estimate. We have webinars to help you with the Report Designer. They can be found here (toward the bottom of the page): Report Designer
If you want to hide the field on the screen you can do that as well. When editing the screen, edit the field you want to hide, select Advanced Options, and check the Hidden checkbox.
If I'm totally off base here, let me know.
