• Follow the steps in Option I if you want to reverse an invoice without affecting a prior period but keep the original invoice.
• Follow the steps in Option II if you want to delete the invoice without affecting a prior period.
• Follow the steps in Option III if you want to make any other change to the invoice without affecting a prior period.

Option I: Reverse the invoice without affecting a prior period but keep the original invoice

1. In Accounts Payable, from the Tasks menu, select Enter Invoices.
2. Enter an invoice exactly like the one you want to reverse with these differences:
   • Change the invoice number slightly - you cannot enter two invoices with the same invoice number.
   • Type a current accounting date. This effectively becomes the accounting date of your reversal.
   • Enter the amount as a negative number, so that this invoice and the original invoice net to zero
3. Click Accept invoice and then click Finish.
4. Using a check date in the current period, either print a zero dollar check or record a zero dollar manual check to pay the two invoices together.

Option II: Delete the invoice without affecting the prior period

Refer to How do I delete an invoice in Accounts Payable?

Option III: Change the accounting date on the invoice to a current period date, and then make changes to the invoice

1. In Accounts Payable, from the Tasks menu, select Change Invoices.
2. Enter the Vendor and Invoice information.
3. In the Accounting Date column, type a current accounting date. This is the accounting date Accounts Payable uses for your invoice changes.
   • Tip: If you do not have an Accounting Date column, change the date in the Invoice Date or Received date column, depending on your accounting date settings in AP Settings.
   • Note: If you are changing a paid invoice, refer to How do I change distribution information on a paid Accounts Payable invoice?
4. Click Accept invoice without making any other changes.
5. In the Reversal Accounting Date window, select Revised accounting date. This creates debit and credit entries in the current accounting period that net to zero. Click OK.
6. Click Finish.
7. Make the appropriate changes to the invoice as usual in Tasks, Change Invoices. Because you changed the accounting date for the invoice to a current period, the changes you make now do not affect prior accounting periods.
