Changing the Customer on an Invoice without Losing Audit Trail in Microsoft Dynamics GP

A common question that has come up recently is ‘How do I change the customer on an invoice?’

Well, in short, it’s not possible without significant unsupported updates to SQL data which compromises the audit trail that is part of a GAAP compliant accounting system such as Microsoft Dynamics GP.

The good news is that there are some tools available in Dynamics GP that can assist you in crediting the original invoice and a new invoice.

Below is a step-by- step example of how to handle the following scenario:

  • a sales order is processed for a customer, and an invoice is sent to that customer.
  • the customer subsequently advises that the order should be paid for by a different company.

The general steps are:

  1. Post the original customer invoice even though it may have the wrong customer listed.
  2. Create a return based on the original customer invoice – verify the correct lot number and/or serial numbers if applicable on the return document.
  3. Review your company policy as to whether commission should be included on the return to reverse the original invoice.
  4. Post the return.
  5. Apply the return to the original invoice.
  6. Create a new invoice for the correct customer but only fill out the header details. Be sure to consult the salesperson and comply with the company policy as to which invoice will track the commission.
  7. Copy the lines from the original customer invoice to the new invoice created for the correct new company.
  8. Allocate line items as needed (you may need to click the yellow triangle) – this might include selecting the lot numbers and/or serial numbers if applicable.
  9. Review and post the invoice per normal procedures.

Invoice INV0000041 for customer ID TIV001 is credited by generating a return and then the same line items are sold on a new invoice to customer ID 2WI001.
