Why Deletion Is Not Allowed and How to Create a Credit Invoice in Eemel.fi
In Eemel.fi, sales invoices cannot be deleted. Instead, you must issue a credit invoice (also known as a credit note). If the correction is internal and the credit invoice does not need to be sent to the customer, you can select “I will print and send it myself” during the invoicing process.
✅ Steps to Create a Credit Invoice
Go to Sales → Invoices
Find the invoice you want to credit
Click the three-bar icon next to the invoice
Select Credit this invoice
You can edit the credit invoice as needed
In the billing settings, choose the option “I will print and send it myself” if the credit is for internal purposes only
