# How to fix an invoice that has been issued for goods at the wrong price

KB80

### Overview

Sometimes you may invoice a Customer for goods at the incorrect price. The following options are available to correct this, and the option you choose will depend on the result you are after and the effort you are prepared to put in. The option you choose may also depend on the paperwork that your customer wants to see.

Never edit the invoice price or change an invoice that has been issued

Option 1: IF THE INVOICE HAS NOT BEEN ISSUED: Delete and re-create the invoice

This option is the easiest and best option if you have not already issued the Sales invoice to the Customer.

1. Delete the invoice.
2. Adjust prices on the Sales order
3. Re-create the invoice

You do NOT have to delete the Dispatch.

Option 2: IF THE INVOICE HAS NOT BEEN ISSUED: Clear the invoice quantity and adjust the sales order

This option is similar to Option 1: IF THE INVOICE HAS NOT BEEN ISSUED: Delete and re-create the invoice, but instead of deleting the invoice, you clear the quantity of the lines you need to adjust.

1. Edit the invoice and clear the Quantity for the relevant lines.
2. Edit the Sales order and adjust the prices as necessary.
3. Edit the invoice and re-enter the quantities you originally removed.

You do NOT have to edit the Dispatch.

Option 3: FOR A QUICK ISSUE OF A CREDIT: Perform a POS / standalone invoice for a full item reversal and re-invoice/dispatch

This option is the preferred option as it allows your sales reporting to report correctly because the original item sale is effectively reversed.

1. Create a Sales invoice for the Customer (not from a Sales order)
   1. Add the actual Item code sold and the MINUS of its original quantity and original price
   2. Add the item on the next line and the positive quantity and NEW sale price
   3. Do this for every item whose price was incorrect
   4. Update and issue to the customer

If you are doing this in a normal invoice, not a POS Receipt, then you need to have the System Preferences A / R option enabled (consider the wider impact of this option).

Option 4: COMPLETE REVERSAL – BEST FOR REPORTING: Return all goods in full, credit, re-deliver and re-invoice

You would use this option if you want to represent the margin that you have made on sale of the goods correctly . This will ensure that all your sales reports show the correct sale vs cost on an item by item basis.

1. Create a Dispatch return for the incorrect goods
   1. Invoice to produce a full credit and issue to the Customer
   2. Edit the original Sales order and add notes indicating that returned in full due to incorrect price.
2. Duplicate the Sales Order to create a new order, and amend the prices
   1. Dispatch the order. Make plenty of notes on the dispatch that the goods have not physically been moved – reference the original Dispatch #
   2. Invoice the order and issue the new invoice to the customer

Option 5: Issue a sundry invoice for the difference in price

This option allows you to issue an additional invoice for the difference in price of the incorrect invoice. It is much simpler, very quick, but has the following disadvantages:

- Your Sales order and sales analysis reports will still show an incorrect profit margin for the incorrect Sales invoice
- You need to manually calculate the difference in price

1. Create a Sales Invoice for the Customer (not from a sales order)
   1. Add a line to the invoice using a non-stock item code such as SUNDRY, G / L Account, CREDIT or any other code that you have created for this purpose
   2. Enter the amount representing the difference in price
   3. Update and issue to the customer

Option 6: Issue a sundry invoice for a full reversal and re-invoice of price

This option allows you to reverse the full price and issue a new price on the same invoice. It gives you greater freedom to express the original and the new pricing. The disadvantage is that your sales analysis reports for the original invoice will still show an incorrect profit margin.

1. Create a Sales invoice for the Customer (not from a Sales order)
   1. Add a line to the invoice using a non-stock item code such as SUNDRY, G / L Account, CREDIT or any other code that you have created for this purpose
   2. Enter the amount representing a MINUS or the original price
   3. Enter another line representing the NEW price
   4. You can also enter a line per item sold, but DO NOT use the actual item code as this will transact the item in and out of stock (see below option for this)
   5. Update and issue to the customer

With all options, consider the timing aspects on your reporting. Even using a full dispatch and return will create reporting anomalies if it occurs in a different month
