Credit note: what it is and how to issue it

A return, a discount after the sale or a wrong amount? An issued invoice is not deleted: it is corrected with a credit note. Here is what it is, when you need one and how to issue it in eFluper.

  • Credit documents
  • myDATA
  • On every plan

In short

A credit note (πιστωτικό τιμολόγιο) is the document a seller issues to reduce, fully or partly, the value of a sale that has already been invoiced, for example because goods were returned, a discount was given after the sale or the amount was wrong. In eFluper you issue credit documents on every plan, like any other document: they are transmitted to myDATA on issue and the credit shows on the customer's statement and balance.

What is a credit note?

It is the document with which a seller reduces, fully or partly, the value of a sale already invoiced, for example on returned goods or a discount given after the sale.

When is a credit note issued?

When the value of an issued invoice has to be reduced: on returns, on discounts given later, to correct a wrong amount or quantity, and when a sale is cancelled after invoicing.

Can I delete an invoice instead of issuing a credit note?

No. An invoice that has been issued and transmitted to myDATA is not deleted or edited; its value is reduced with a credit note. For special cases, such as a document issued by mistake, ask your accountant.

Is a credit note sent to myDATA?

Yes. A credit note is a tax document and is transmitted just like an invoice. eFluper sends it automatically on issue and it comes back with its MARK and QR code.

Which eFluper plan includes credit notes?

Sales credit documents are on every plan, Light included from 8 €/month. Recording purchase credit notes from suppliers is on Small, Medium and Large. See the plan comparison.

What is the difference between a credit note and a debit note?

A credit note reduces the value of an invoiced transaction, while a debit note increases it, for example for extra charges that arose after the invoice was issued.
