When entering invoices, the "Tax" at the bottom of the invoice may not match the vendor's sales tax amount. I have to create an additional entry to a suspense account to get it to calculate correctly. Some vendors appear to calculate the sales tax on an item by item basis while other subtotal the taxable items and then calculate the sales tax.

It would be nice to have an option that allows for an adjustment to the sales tax computation in the invoice to match the amount on the vendor's invoice without having to add another line to the invoice.
