We also have a client experiencing this. When the Sales Order Invoice is printed, it displays the correct amount of sales tax. However, after updating the Sales Journal and Daily Transaction Register, the Sales Journal is not out of balance, but it is missing the sales tax and the Daily Transaction Register is out of balance missing the credit amount for the sales tax. The invoice when viewed in Customer Maintenance is missing the sales tax. This is happening sporadically with no apparent patern. We have a case open with Sage and have submitted our clients company data.
