How does pre-numbering receipts stop false receipts to be issued? -

I don t quite understand what false receipts are and how losses can occur for the business issuing the false receipts.And how does pre-numbering receipts help to solve this problem. Please help!

I used to work in a clothing shop that had pre-numbered receipts. We used to write up the various merchandise, tax, and total on the receipts. For instance, we d write something like Blouse, $60, slacks, 55, Subtotal $115 and then we d calculate the tax and add up the subtotal and tax to get the total. If we didn t have the pre-numbered receipts, we could easily write up a receipt, take the money from the customer, make change, and then take that sales money out of the register and put it in our pocket, and not submit the store copy of the receipt. The books will balance, until it s inventory time. Even when the inventory comes up short, the loss is blamed on shrinkage, which could mean that the employees are dishonest, or it could mean that some of the merchandise was shoplifted, or a combination of these two factors.When the receipts are pre-numbered, if an employee tries to take the cash for the merchandise, she can t just destroy or fail to submit the receipt, it will leave a gap in the numbering sequence. Her boss or the accounting department will wonder why the sequence goes from #289 to #291. They will insist on finding receipt #290. If the transaction on #290 was voided, then both the customer and store copy of the receipt will be submitted, to prove that a receipt wasn t falsified.
