WHAT CHANGES
The way you send and receive an invoice changes
Bookkeeping stays the same. The invoice format and the route it travels change.
Peppol network
The invoice does not travel by e-mail but through a network of digital postmen. Delivery can be proven.
Reporting to the tax authority
The digital postman reports the invoice data. You do not have to send it separately.
Receiving invoices too
You must be able to receive an e-invoice, not just issue one.
WHO IT AFFECTS
It affects VAT payers and non-payers
VAT payers
You must issue and receive e-invoices for domestic supplies between businesses (B2B) and to the public sector (B2G). This covers limited companies, joint-stock companies and sole traders who are VAT payers.
VAT non-payers
You must be able to receive an e-invoice. Issuing is voluntary for them. Check exceptions and details with a tax adviser or in the tax authority's guidance.
The information is indicative and is not legal or tax advice. The binding sources are Act No. 385/2025 Coll. and the guidance of the Slovak Financial Administration.

WHAT YOU GET
What Innovanet does for you with e-invoices
Issuing an e-invoice
You create the invoice in a form and Innovanet builds it as XML in UBL 2.1 (Peppol BIS 3.0). The payment QR code stays.
Sending with tracking
You send an e-invoice with one button. You see the status of every invoice and, if it fails, the reason.
Receiving incoming e-invoices
Supplier invoices download automatically, with the PDF rendering if there is one.
Matching by IČO
Supplier, IBAN and order are matched automatically and you turn the invoice into a record with one click.
Export to accounting
You export the data to POHODA, Money S3 and OMEGA, so the accountant retypes nothing.
AI for PDF invoices and receipts
AI reads documents that are not e-invoices and fills in the supplier, IČO, dates, amounts and VAT.
