QuickBooks figures tax amounts differently than our Estimating Software.  This results in a penny to a two penny overage on the amount the customer owes in QuickBooks.  Since the customer pays from the Invoice created from the Estimating Software I have to create an Invoice in QuickBooks to match the Estimating Software so that my receivables will be correct.  I have been discounting this off to customer underpayments.  I noticed today that this discount is appearing on my sales tax liability report as a payment.  I didn't receive the money so it shouldn't be taxable.  The same issue arises when writing off bad debts, which should not be considered income on the tax reports.  I found the solution listed here on the community.  It is quite laborious for a one to two penny difference that occurs on at least 75 percent of our Invoices.  Is there a simpler fix for this?  Since I am not the only one dealing with this issue, would QuickBooks devise a fix that won't affect our tax reports?  It seems like you could make a change to the discount item to make it non taxable income or create an item that was for writing things off that were not collected that was not adding the discount amount as taxable income.  Thank you for your time and attention.  We love QuickBooks and are thankful to have such a user friendly bookkeeping software available.
