What does the EVERIFIN digital postman do?
Conversion, encryption, delivery via Peppol, reporting to the Financial Administration and archiving — we do it all in the background.
EVERIFIN always offers more
Extended archiving
Statutory retention is not a Peppol service — we handle it for you. Secure storage within the EU, accessible at any time.
Europe‑wide coverage
You send cross-border invoices just like domestic ones. You will be ready for the ViDA regime from 2030 with no further integration.
Invoice and payment in one
You can check a received invoice and pay it from any of your bank accounts directly in EVERIFIN.
Accounting AI agent
Every accounting case has a solution. The AI finds it and helps you handle accounting cases faster and with greater certainty for your company.
All your documents in one place
Receipts are processed too — with no needless paperwork and nothing getting lost.
Financial overviews
You get a better view of your company’s costs and revenue, which lets you plan your budget and manage company finances more effectively.
What the law says
An amendment to the VAT Act (Section 76a, Act No. 222/2004 Coll.) introduces mandatory e-invoicing through the European Peppol network.
Questions
Do I have to send e‑invoices even if I am not a VAT payer?
From 1 January 2027, VAT payers must issue e-invoices. Every taxable person, however, will have to receive them — including sole traders and self-employed people who are not VAT payers, landlords and farmers.
Is it enough to send invoices by e‑mail as a PDF?
No. Once the law takes effect, neither a PDF nor a scan counts as an e-invoice. The invoice must be in a structured format and delivered through the Peppol network by a certified postman.
My ERP sends invoices in a format other than Peppol BIS — what do I do?
We take care of the format for you. We accept your output and convert it to Peppol BIS before sending — you don’t have to change anything in your system.
A supplier claims they sent me an e‑invoice, but it never arrived in my ERP. What should I do?
In EVERIFIN you can see the delivery status of every invoice together with a timestamp. If delivery failed, you will see the reason and you can re-deliver or download the invoice.
What is archived, for how long and where?
We archive both the structured e-invoice and the delivery confirmations, in line with Slovak legislation, within the EU. You can access the documents at any time throughout the entire retention period.
How can I test the integration before going live?
You get a test environment and a test Peppol account. The voluntary phase from Q2 2026 exists precisely so that you can go through your processes without any risk.
What are the penalties for non‑compliance?
Failing to comply with mandatory e-invoicing is a breach of the VAT Act and the Financial Administration can impose a fine for it. The exact amount is set by the tax authority according to the severity.
- REST API — sending and receiving UBL documents
- Validation before sending
- Real-time delivery status
- Partner lookup in the Peppol network
