New: E-invoicing is coming to the EU. Get early access to compliant invoicing
EU e-invoicing mandate · ViDA

E-invoicing is becoming mandatory. Are your invoices ready?

Mandatory e-invoicing is rolling out across the EU, country by country, through 2030 — and Germany already requires every business to be able to receive one. Here is what it means for freelancers and small businesses, in plain language.

The core idea

A PDF is not an e-invoice

This one distinction is what the whole transition is about. It is simpler than it sounds.

Comparison of a PDF invoice and an e-invoice On the left, today's PDF invoice is a picture that a person must retype and is being phased out by law. On the right, an e-invoice is labelled data that software reads automatically and is becoming mandatory country by country. TODAY · PDF INVOICE A picture for humans INVOICE #2026-014 Consulting · 10 days 1,000.00 VAT 20% 200.00 TOTAL 1,200.00 A person retypes every field Slow, and easy to get wrong Being phased out by law ≠ THE E-INVOICE Labelled data for software seller_vat ATU12345678 net 1000.00 vat_20 200.00 total 1200.00 due 2026-07-10 Software reads it instantly No retyping, no errors Mandatory, country by country

A PDF is a picture of an invoice, made for a person to read. An e-invoice is the same information as labelled data that software can read on its own — the seller's VAT ID, the net amount, the tax, the due date. The new rules require the second kind, which is why simply emailing a PDF will not be enough.

The timeline

When does it become mandatory?

There is no single EU switch-on date. Each country sets its own timeline, leading up to EU-wide rules for cross-border trade in 2030.

DE
Germany
–

Every business has had to be able to receive e-invoices since January 2025. The duty to send them phases in from 2027 to 2028, depending on company size.

Receiving already in force
BE
Belgium

Structured e-invoicing for domestic B2B transactions became mandatory from January 2026, making Belgium one of the first movers.

In force
FR
France
–

All businesses must be able to receive e-invoices from September 2026, with sending obligations phasing in for smaller businesses through 2027.

Rolling out
PL
Poland

The national KSeF e-invoicing system becomes mandatory for businesses during 2026, phased in by company size.

Rolling out
AT
Austria

E-invoicing to the federal government is already required. A broader B2B mandate is expected within the ViDA window — voluntary today, but worth preparing for now.

EU-wide · ViDA

Structured e-invoicing and digital reporting become the standard for cross-border B2B trade between EU member states from July 2030.

The horizon

Am I affected?

Find yourself below

Short, plain answers for the people who ask us most often.

Yes — to receive

Freelancer in Austria with German clients

If you invoice German businesses, they may already expect to send and receive e-invoices. You should be able to accept one today, and be ready to issue one as Austria moves.

Yes — being exempt doesn't exempt you

Kleinunternehmer (VAT-exempt)

Not charging VAT does not exempt you from the format rules. In Germany, even small businesses must be able to receive e-invoices — the exemption is about VAT, not about the file format.

Yes — sooner than you'd think

Small GmbH or limited company

Registered companies are first in line for sending obligations. Depending on turnover and country, your duty to issue e-invoices may begin in 2027 — plan for it now, not later.

Yes — cross-border is the 2030 target

Agency invoicing clients abroad

If you bill clients in other EU countries, the ViDA cross-border rules from 2030 are aimed squarely at you. Each client's home country may also have its own earlier deadline.

FAQ

The questions everyone asks

Straight answers, no jargon — and where a term is unavoidable, it is explained in the same breath.

Is a PDF invoice sent by email an e-invoice?
No — and this is the misconception the whole transition exists to correct. A PDF is a picture made for a human to read. A true e-invoice is structured data that software reads automatically, in a format like XRechnung or ZUGFeRD. Emailing a PDF will not meet the e-invoicing obligation.
What is the difference between a PDF and an e-invoice?
A PDF is built for the eye: a layout that only makes sense once a person looks at it. An e-invoice is built for software: every value — the seller's VAT ID, the net amount, the tax rate, the due date — is a labelled field another system can import without anyone retyping it. The law increasingly requires the second kind.
When does the e-invoicing obligation begin?
It depends on your country. Germany has required every business to be able to receive e-invoices since January 2025, with sending obligations phasing in from 2027 to 2028 by size. Belgium's B2B mandate began in 2026, France and Poland are rolling out in 2026 and beyond, and EU-wide cross-border rules apply from July 2030 under ViDA.
Does the obligation apply to Kleinunternehmer and small businesses?
In most cases yes, at least for receiving. In Germany the duty to receive e-invoices applies to all businesses, including small businesses and Kleinunternehmer under the §19 VAT scheme. Being exempt from charging VAT does not exempt you from the format rules. Sending timelines are more generous for smaller businesses, but you should be able to receive an e-invoice today.
What is ViDA?
ViDA stands for VAT in the Digital Age — a package of EU reforms that modernises how VAT is reported. One of its core pillars makes structured e-invoicing and near-real-time digital reporting the standard for intra-EU B2B trade, with the cross-border rules applying from July 2030. Many member states are already moving ahead with their own national mandates.
What are XRechnung and ZUGFeRD?
Both are German e-invoice formats that follow the European standard EN 16931. XRechnung is pure structured data (XML), used heavily for the public sector. ZUGFeRD is a hybrid: a normal-looking PDF with the structured data embedded inside, so a person and a machine can both read the same file. Either satisfies the format requirement where it applies.
What is Peppol, and do freelancers need it?
Peppol is a secure network for sending e-invoices between businesses across borders — standardised plumbing, so your invoice arrives in your client's system in a format it understands. You don't manage Peppol yourself; your invoicing tool connects to it for you. The practical question for a freelancer is simply whether your software can deliver a compliant e-invoice.
Does PayFlowAI already create compliant e-invoices?
Not yet. EU-compliant formats (ZUGFeRD and XRechnung) and Peppol delivery are in active development, and early access is open now. Today PayFlowAI already helps you get paid faster with Natural Language Invoice Creation, automated multi-language reminders, and multi-currency tracking.
