How to get a VAT invoice from an IKI receipt

IKI issues a VAT invoice through its self-service using the receipt serial, the three part code printed above the total, the date and the total. How to do it yourself and how kvitas.app does it for you.

Why the receipt is not enough

A cash receipt is not a VAT invoice. Without one the input VAT stays unclaimed. The one exception is a fuel receipt up to 150 EUR that carries the buyer’s details, which Lithuanian VAT law treats as a VAT invoice in its own right.

Which numbers on the receipt matter

An IKI receipt prints two things on one line above the final total: a four digit serial number and a three part code in the form XXXX/XXXX/XXX. The self-service needs both, plus the purchase date and the final total. The total must be written with a comma.

How to do it yourself

  1. Find the serial number and the three part code above the total.
  2. In the IKI invoice self-service enter the date, the serial number, the three part code and the total with a comma.
  3. Choose legal entity and enter your company code. The name, VAT code and address are filled in from the register.
  4. Download the generated PDF.

Deadline and limits

If an invoice already exists for the receipt, the self-service shows the existing one immediately instead of creating another. The deadline for issuing an invoice is being confirmed and this page will be updated.

How kvitas.app does it

You send a photo. We read the serial number, the three part code, the date and the total, and request the invoice from IKI’s self-service on your behalf under your company code. IKI itself issues the invoice. If one already existed, we simply retrieve it. The PDF comes back within a minute. We use only the public self-service and never circumvent security measures.

Common problems

Total rejected: a dot was entered instead of a comma. Receipt not found: usually the serial number and the three part code were swapped, or one part of the code is missing. Details not filled: check the company code, the system takes the data from the register.

Frequently asked questions

Where is the three part code on the receipt?

Directly above the final total, on the same line as the four digit serial number. It looks like 7885/0594/0029.

How do I enter the total?

With a comma, for example 37,63. The IKI self-service does not accept a dot.

What if an invoice already exists for this receipt?

The self-service recognises that and shows the existing invoice straight away. kvitas.app then only retrieves it.

Does it work for fuel receipts?

Fuel receipts do not need an invoice. Under Lithuanian VAT law a fuel receipt up to 150 EUR that identifies the buyer already counts as a VAT invoice.
