Reverse a purchase order

Description

You may need to correct or delete a purchase order that was updated incorrectly. The steps depend on the status of the invoice created from the purchase order.

Cause

Resolution

Reversing incorrectly delivered order

If a purchase order is delivered in error or with incorrect values, you must reverse this manually.

You can amend the purchase order in one of the following ways:

Delete then re-enter the purchase order

Memorise the order before deleting it. You can then recall it and make any required changes.

Amend the purchase order to add the quantity of stock that needs to be delivered again

Add a new line, or amend the existing product line quantity.

Amending a completed purchase order or putting items back on order can create duplicate batch invoices when updated.
Edit the batch invoices to remove the duplicates.

Adjusting the relevant stock records

Sage 50 Accounts uses First In First Out (FIFO), so an Adjustment Out (AO) removes the oldest stock, not recently delivered stock.

Read about the exact method in our adjust stock records after deleting or reversing a purchase order article.

To correct the purchase invoice

If the order has been updated as well as delivered, the purchase invoice may also be incorrect. To correct this, delete the original invoice using the Corrections option then update the new or amended purchase order to re-post the invoice.
