Accounting programs ePošťák works with

Clients keep their accounting program. They upload issued invoices from it to ePošťák, which sends them over Peppol. You export received e-invoices back into the program you keep the books in.

◆ Frequently asked questions

Accountants' frequently asked questions about e-invoicing

Do I have to pay for the accounting workspace?

No, never. The workspace for accountants and accounting firms is completely free. Your clients choose a plan that fits their needs — you pay nothing for management and export.

How does a client connect to me?

The client first selects Kaja Solutions s.r.o. (ePošťák) in the Financial Administration's VPDS application. The company owner then invites you by email as an accountant and chooses View only, Accounting or Full accounting access. You accept the email link and the company appears in your accounting workspace. If you hold valid authorisation for that taxable person, you can make the VPDS selection on the client's behalf.

What can I do on behalf of a client?

It depends on the access selected by the company owner. View only cannot change the company. Accounting allows accounting operations and exports. Full accounting access also allows creating and sending invoices on behalf of the company under its approval rules.

Which accounting programs do you support?

Import from and export to the accounting software: POHODA (XML), KROS Omega (TXT), Money S3 (XML), MRP-K/S (XML), ABRA Flexi (XML), DUEL (XML) and PROLUC (import of ISDOC/UBL XML, export of received invoices as a .PRO file), plus ISDOC 6.0 and Peppol BIS 3 (UBL XML). Export to CSV for Excel as well. A bulk export downloads as one file with a separate export per client. If your program is missing, let us know.

Will you help me even if my client uses ePošťák for free?

Yes. We are of course available to accountants even when their client uses ePošťák on the Free plan. We help with imports, exports and client setup at info@epostak.sk.

I manage 200 companies. Is that a problem?

No. The number of clients is not limited. You see the documents of all companies in one list and switch between companies with one click.

What if a client changes their digital mailbox provider?

E-invoices already delivered through ePošťák remain accessible. New invoices will arrive through the Peppol network at the new provider. The archive is not lost.
