More information for e-shops before the start of EET

More information for e-shops before the start of EET

We are just days away from the launch of electronic sales records for retailers. We bring you more detailed, useful information.

EET and Heureka Cart

One of the issues related to EET that has been highlighted in recent days is the implementation of electronic records when using the Heureka Basket service. The Ministry of Finance has issued an opinion that e-shops must send data messages with sales data to the registry at the latest when they become aware of the payment.

Therefore, Heureka Košík now offers its clients a component on the basis of which the sales information is transferred to the EET by the provider itself. This is therefore an assumption of responsibility for the information and only applies to situations where customers will be using online card payments when making purchases through Heureka Basket.

Until 1 March, you need to tick in the EET tab in the Heureka administration whether you delegate the registration of card payments in the Heureka Basket to Heureka (YES); or whether you have implemented a payment gateway on your website and register the sales yourself (NO).

If you delegate the registration to Heureka, you will receive a pdf. file in your email which you have to sign and send back to Heureka. After receiving and checking the document, Heureka will send you an email to approve it and activate EET.

If you are not sure how to set up EET in Heureka Basket, please do not hesitate to contact us, we will help you. For more information, please visit the Heureka blog.

EET Receipt Opportunities

Another important issue with the introduction of EET is the methodology of how to get your receipts to look right from an EET perspective and not risk penalties. So let’s remind ourselves what such a receipt must contain.

1) FIK (fiscal identification code) – a unique 39-digit code generated by the EET system in the confirmation data message of receipt of the recorded sales.This does not apply to businesses recording sales in simplified mode, they only provide their signature code

2) TIN (tax identification number)

3) Operation identification of the establishment where the sales were made – the entrepreneur obtains this by filling in the details of the establishment in the EET web application

4) Designation of the cash register where the sales were made – the designation is created by the entrepreneur

5) Receipt serial number

6) Date and time of receipt of sales or issue of the receipt, if earlier, including seconds

7) The total amount of the sale including VAT

8)Payer’s security code – 44 digit PKP code fingerprint generated by the payer’s POS device

9)Indication whether the revenue is recorded in normal or simplified mode

10) Taxpayer identification number of the taxpayer who has authorised the taxpayer who records the sales to record the sales – of course, this is only provided if the taxpayer records the sales for another taxpayer

For more information, see the Treasury’s statement on online payments
