We just had (yet another)POS crash when trying to tender a sale. Normally we can make the adjustment for cash/credit/debit at closing but this time it was on a Gift Certificate and the system doesn't grok that and even though it shows the items as sold, it did not subtract the sale from the GC and now shows the GC balance as 164.54 higher than it should be.
Also I just realized that Gift Certificates seem to be double entering in Sales, as Sales includes the GC being sold initially AND then again when the GC is used. Meaning that our Total Sales Volume could be thousands of $$$ off.
Any help at all on this ?
