We have invoiced a customer and overcharged an item in the invoice. The customer requests a credit note for overcharging him.
The goods are not to be returned but a credit note has to be passed for the difference. We cannot issue him with an invoice as the previous one already sent to him is already allocated some reference with the government authority.
How can we best tackle this business scenario, which will adjust the inventory value(hence give the correct gross profit for the item), sales and customer account?
