Shawn, Recently we've had a tax change here in Canada effective 01-Jul-06. We've updated the sales tax table along with each customers settings. When we credit back an invoices that has the previous tax rates, it changes the historical invoice to the new tax rate. Is their a settting I can set to avoid this? Thanks,
To be honest, I can't think of a way to do that... the tax rate is per customer, not per invoice. So you might have to do those manually (reversals on a different tax rate).
