How to change the value of a sales invoice after it has been receipted

KB72

Once you have applied a Receipt to a Sales invoice, you are no longer able to change the value of that invoice (because the value of the invoice and its allocation is stored in the receipt data).

You should never change an Invoice that has already been issued. If you have already issues the Invoice, please see How to fix an invoice that has been issued for goods at the wrong price for more options.

If you need to change the value of a sales invoice, the following process can be used:

  1. Locate the receipt on which the invoice has been allocated
  2. Edit the receipt and remove the invoice allocation. Do not just make it zero, delete the entire entry
  3. Update the receipt. This will create an over-allocation credit – don’t worry about this, it will be removed in the next steps
  4. Modify the Sales Invoice to the value that you need
  5. Go back to the Receipt and add the invoice allocation back on. Update
    • This will remove the over-allocation invoice that was created

Additional notes

  • If the invoice or the receipt are dated in a period that has been locked, you will need to unlock that period
  • If the original receipt on which the invoice was allocated was not fully allocated, it will have created an over-allocation invoice. If this invoice has also been receipted (taken up), then you will not be able to modify the receipt record
