My reports in POS don't always match.  I have been checking the figures between my sales tax detail report and the X-out report for the corresponding period, and they will be the same for a few weeks, and then they are different.  I have additionally checked the transactions against the sales detail report, as well as the sales tax detail report.  There are methods that seem strange to me but are explainable but still have not found what is causing the discrepancy in the reports.  For example; The sales item detail report shows a payment to account (paid with credit card) but under sales activity on the Z-out report it is not listed.  My assumption?  Because it was paid by credit card Quickbooks is treating it differently.  Also, in the sales item, it does not show the full amount of a return and it's accompanying sales tax (if applicable) just the sales tax portion.  Again, assuming this is QB's treatment.  However, factoring these things in, the reports still don't match.  Should I not be able to reconcile my reports as a checkpoint and verification?  And why does it seem so hard to locate this kind of information about the product online?
