We use Xero. Xero has very rigid GST rules that do not cater for invoices that contain many line items, some that include GST and some that don't. I cannot expect staff to do any manual calculations therefore I want a standard inclusive GST policy that allows GST amount override. The expenses app must then split the invoices into two lines for import into Xero: 1. tax free and 2. tax inclusive. Can Expensify do this?
