Credit notes and corrective invoices

You cannot edit an issued invoice. Correct an error or subsequent change by issuing a new document that refers to the original invoice. You can change a draft you have not issued directly using Edit.

Which option to choose

Credit note

The amount is reduced: the customer returned goods, made a complaint, received a later discount, or you need to reverse an entire invoice they have already received.

Corrective invoice

The price, quantity or another detail changes, and the difference may also be in your favour, for example if you forgot to charge for delivery.

Cancellation

The invoice should never have been created and the customer has not received it yet. A cancelled invoice stays in the records with the Cancelled status. Only an owner or administrator can cancel it.

Credit note

1. On the invoice detail, click Credit note.
2. For each item, enter how much you are crediting. Enter zero for items that are not affected.
3. In Reason, explain why you are issuing the credit note, for example returned goods or a complaint.
4. Click Create credit note. This creates a draft for you to check and issue.

All credit notes against one invoice together cannot exceed its amount. Once credit notes cover the whole invoice, its status becomes Credited and it is no longer counted as unpaid.

Corrective invoice

1. On the invoice detail, click Corrective invoice. This creates a draft containing a copy of the original invoice items.
2. Edit the items to show what they should have been. Do not subtract the original amounts; Vystav does that.
3. Issue the corrective invoice. When issuing it, Vystav adds the original items with negative quantities, so the issued corrective invoice contains only the difference.

If you correct the same invoice a second time, the new corrective invoice starts from the latest corrective invoice, not the original. This avoids subtracting the original items twice.

VAT and e-invoices

Credit notes and corrective invoices appear in the invoice list. In the Slovak VAT control statement (kontrolný výkaz), they go into section C.1 as the difference from the original invoice. See VAT reports in XML.

If the original invoice was sent as an e-invoice, the corrective document must follow the same route (§ 85o(5) of the Slovak VAT Act). Vystav warns you about this when sending.
