Start with the evidence
Preserve the original reference and identify the field being corrected. Gather the request and approval for the change instead of replacing the original file with a new document of the same name.
Work through the example
The source customer reference is PO-00428, while a draft showed PO-00482. This is a reference correction. It does not justify changing the service description, amount or payment status at the same time.
Make the next step clear
Follow the correction procedure appropriate to your business and document type. Link the resulting record to the original and explain the reason briefly. A clear trail is more useful than hiding the first version to make the folder look tidy.
Keep the source context
An invoice record and a customer conversation provide different evidence. Keep original document references stable while adding dated notes about replies and related payments. These guides concern clear administration, not collection tactics or promises of automated money movement.
