Bellamy
If the Report Web Module is available in Bellamy then there should be a report called "Paid Invoice GST & PST Analysis". This report comes in Excel.
Invoice Data From: Format is: DayMonthYear
For clients who dont have the Report Web Module we have had success with two reports called Paid Invoices & Paid Invoice Tax Analysis. The first one contains the invoice amount where the second one has the tax amounts and we are able to join both reports based on the common fields in both files.
The files for both reports are using ReportBook as their filename.
