ByD is using the posting date of the supplier invoice to calculate sales and use tax. I know at one time ByD calculated the sales tax based on the supplier invoice document date, which is how it needs to be for audit purposes. Now we had a rate increase effective 10/01/16 but I have about $500,000.00 of payables to enter dated before October when sales tax was lower. I don't have time to go line item by line item to adjust the tax date. Two part question why can't ByD get it right and any suggestions to have sales tax calculated based on the document date not the posting date?
