Sometimes an error may have been made on an invoice and the easiest way to fix this is to reverse the invoice, create a new invoice based on the reversed invoice, fix the error and then accept the corrected invoice.

1. Open and Login to the POS Works System Menu.
2. Navigate to the Invoice Matching program.
3. Search and select the required invoice.

4. Select Reverse Invoice.
5. Enter User ID and Password.

6. A prompt message will appear. Are you sure that you want to kill invoice [Purchase Invoice ID]
7. Select Yes.

8. A prompt message will appear. Would you like to create a new invoice based on the one just killed?

9. Select Yes. Yes - the invoice needs to be reprocessed with different costs, quantities or some other reason. No - if invoice was a complete double up or needs to be removed.

On New Invoice, changes can be made manually to:
- Carton size
- Quantity
- Status
- Cost
Select Save and Accept to finalise Invoice.
