More detail
Returns and corrections are normal in retail. The credit note exists so these are recorded transparently rather than handled off the books.
Because the credit note links to the original invoice, the net position stays accurate for both your records and KRA. Make sure staff know how to raise one so a refund or return is not left as an untracked cash adjustment.
