The instinct when an invoice is wrong is to fix the invoice. That instinct creates a problem that only surfaces at audit, by which point it is everywhere.
A customer returns half an order. The price on the invoice was wrong. The quantity was keyed as twelve instead of two. Every business hits this weekly, and the natural response is to open the document and correct it. A correction does not replace the original document. It references it. That distinction sounds bureaucratic and is the whole of the thing: the record is supposed to show what happened, including the part where something was wrong and then was put right.
Why the trail matters more than the tidiness
An edited invoice is tidier. It says the right thing now. What it no longer says is that it ever said anything else, and that gap is exactly what an audit is looking at. A business that edits invoices generally does not discover the consequence for a year or more. The consequence is that its records cannot be reconciled against anything - not against the customer's copy, not against the payment, not against what the stock did. Each individual edit was reasonable. The accumulated effect is a set of books that quietly disagree with every other record of the same events.
The thing that catches businesses that changed channel
There is one specific rule worth knowing before you need it: a credit note is raised from the same solution that raised the original invoice. That is fine until a business moves - from a browser to installed software, or from one setup to another - and then needs to correct something issued under the old one. If access to the old channel is gone, the correction has nowhere to come from. It is a small piece of foresight that costs nothing in advance and a great deal afterwards: when you change channel, keep the ability to reach the old one.
The practical habit
Find the original before you attempt the correction, because the correction refers to it. Keep the reference. And resist re-issuing repeatedly when something fails to go through - a duplicate that does succeed becomes a second correction problem on top of the first. None of that is a statement of what the rules require; for that, check with KRA. It is what tends to go wrong in the order it tends to go wrong in.

KRA notes that a credit note can only be generated from the same solution that raised the original invoice.
