Missing Sales Tax Payment
I have a tax-exempt customer who believes she was charged sales tax on her last payment to me. The invoice, sales tax report, and payment details all show she was not charged sales tax, nor did I receive any sales tax. However, she has provided me with a transaction detail showing that sales tax was charged to her credit card for payment of this particular invoice. She has requested a refund. Where did that sales tax money go? And how do I get it back for her?
