i'm working with NS support on this but they're not finding anything yet so I'm wondering if anyone else has seen something like this - on one invoice generated, tax codes are set on individual lines (of time entry). on another invoice generated with the same exact form through the same bulk invoicing screen with the same item, there is no tax code on the line items but instead a tax code field is available on the "accounting" tab to set the tax code for the entire invoice. "Per-line taxes on transactions" has been enabled this whole time. we don't really mind having it on the header level in the accounting tab (the only reason for per-line is to ensure expenses aren't taxed, which still occurs); but not having it consistent/not knowing why it changed is making me nervous that it might change back suddenly.
