I'm not quite clear on what you mean by "do not match".

If you mean that you computed the sales tax for each taxable item, added
your computed tax amount, and found that the sales tax charged was
different, that's because in many (?most) states with sales tax, the tax
is computed, by law, on the total of the taxable items, not on the
individual items.

Like you (if that's what you're doing), I include sales tax as part of
the cost of each taxable item, and then I do sometimes find that my
total tax is a penny more or less than the tax on the receipt. It's not
a "vendor software problem", but the mathematical issue that Michael
Novack alludes to.

If that's not what you're doing, what exactly is not matching to what?
