Receipts through eparagony.pl, without keying the whole day into the till every evening

The sale from an order in OpenLinker goes through eparagony.pl straight to your online fiscal printer. Your rules send orders with a tax ID (NIP) to an invoice, and you see the receipt number and the e-receipt link on the order.

In short. OpenLinker is open-source order management software with a 0 zł licence that passes the sale from your orders to eparagony.pl. Your online fiscal printer registers the receipt, and you see the receipt number and the e-receipt link on the order. OpenLinker won’t pass the same sale on twice.

Sound familiar?

An evening at the till with a list of orders

Item, price, rate, next order. At a hundred sales, one typo in an amount is enough, and the receipt no longer matches the order.

The company asked for an invoice and got a receipt

The tax ID was on the order, but in the evening rush it went through like all the others. You can no longer issue a company invoice for a receipt without a tax ID.

Was this receipt even created?

The receipt sits in the printer, the order in the system, and nothing links them. When a customer asks for proof of purchase, you search for it by amount and time.

Tuesday: 120 orders, 14 companies with a tax ID and a printer that loses its connection in the evening

  1. 09:12A marketplace order for 87,50 zł has just been paid, with no tax ID. A minute later the order shows the receipt number and the e-receipt link.
  2. 13:40A company buys and gives its tax ID, so a rule sends the order to an invoice. There won’t be a receipt.
  3. 21:30The printer loses its internet connection for the night. Three orders wait, and in the morning you click “Check” on each and see that the receipt is registered, once.

Who is responsible for what, and who you call

Your fiscal printer issues the receipt. Every part of the journey has someone looking after it, so for every question you know who to turn to.

You, as the seller

You issue the receipt and collect the buyer’s consent to an e-receipt. A clause in your shop terms is enough, and eparagony.pl provides the ready wording.

Your service technician

Prepares the online fiscal printer: turns on e-receipt mode and programs the VAT rates. For anything about the printer, you call them.

eparagony.pl

Receives the sale and controls the printer through its own program on the computer next to it. Support: pomoc@eparagony.pl, on working days 8-18.

OpenLinker

Takes the sale from the order, chooses the document by your rules, shows the status and link on the order, and checks an unconfirmed receipt instead of sending it again.

Issuing the receipt is always the seller’s duty, even when it’s printed by a printer controlled by eparagony.pl. Whether mail-order sales need a cash register depends on what you sell and how, so agree that with your accountant. Sources: eparagony.pl terms v1.29, §6; cash register exemptions: Dz.U. 2024 poz. 1902.

You don’t have to take our word for it

Questions about receipts through eparagony.pl

Does OpenLinker do the fiscal registration?

No. Your fiscal printer registers the receipt, and eparagony.pl controls the printer. OpenLinker provides the sale details from the order and shows what happened to them next.

Can a receipt register twice?

No. Issuing by hand and issuing automatically use the same key, so for eparagony.pl it’s still the same sale. When confirmation is late, OpenLinker asks for the status instead of sending the sale again.

Receipts through eparagony.pl and invoices through another program. Is that possible?

Yes. Rules send receipts to eparagony.pl and invoices to the program you connect to OpenLinker, for example inFakt, or through eparagony.pl to KSeF. Every order still gets one document.

How does the buyer get the e-receipt?

The link is on the order, and you pass it on like any other document, for example in a message on the marketplace. You need the buyer’s consent for an e-receipt, and a clause in your shop terms is enough for that. You’ll get the ready wording from eparagony.pl.

The printer was offline all night. What about the receipts?

They wait for confirmation. In the morning, once the printer is back online, you check each order with one click. No sale registers a second time along the way.

Start with one receipt, in one click

To begin with, you register each receipt by hand on the order. Once you see the number and link match, you turn on issuing after payment. We can go through the printer and eparagony.pl setup together on a call.
