France’s e-invoicing mandate went live on September 1, 2026, after being announced back in 2020 and postponed three times. It’s a milestone worth pausing on, not just because France is done waiting, but because it marks the start of something bigger: a wave of e-invoicing and tax compliance mandates rolling across Europe and the Gulf that will reshape how global AP and AR teams operate through 2027 and 2028.
On a recent episode of Extropy on Air, Mike Jasper (VP at Extropy Advisors) and Akanksha Birjuka (Project Manager at Extropy) walked through what’s live now, what’s coming next, and the details that trip up multinational finance teams every time. Here’s the rundown, country by country.
A quick note before we dive in: this is public regulatory information, not tax advice. Every organization’s compliance position is its own, and should be confirmed with your own tax advisors.
Why This Wave Looks Different
E-invoicing compliance has a well-worn pattern. It started in South America as a way to fight tax fraud: every invoice sent to the government for validation before the tax could be assessed. Europe adopted the same idea for a different reason, mainly to collect tax faster and improve government cash positions, and that’s what drove the first wave of EU e-invoicing rules.
What’s happening now is the next layer: e-reporting. Beyond just sending or receiving an invoice electronically, e-reporting requires the lifecycle messages around it, confirmation the invoice was received, notice that it was rejected, and so on, to be reported back to the government automatically. France’s mandate is the clearest example of this today, and it’s a reasonable preview of where a wider EU regulation (like ViDA) may eventually head. Even organizations with no French operations should watch this trend, because it’s likely to spread.
France: Live, But Not Fully Tested
France’s mandate is more complex than most because it pairs e-invoicing with e-reporting. Every invoice’s lifecycle events (sent, received, rejected) has to be reported to the tax administration, which adds a layer of failure points beyond the invoice itself.
The rollout numbers are worth sitting with. As of September 1, roughly 170 Basware customers were live and able to receive invoices on the platform. On the regulatory side, France’s tax authority (the DGFIP) has accredited 150 platforms, with about 16 more awaiting approval, for a total of roughly 166 platforms once fully accredited. But as of June, only about 20 of those platforms had actually gone through the official pilot testing program. That means somewhere around 130 newly accredited platforms went live without going through the testing most would consider standard practice.
What that means in practice: expect hiccups. With a supplier, its platform, the buyer’s platform, and the buyer all in the chain, plus lifecycle messages moving in both directions, there are a lot of potential points of failure. AP and AR teams should expect some failed lifecycle messages that aren’t actually failed invoices, and will need a process to tell the difference rather than assuming every failure is a real one.
France has also confirmed a grace period: no financial penalties through the end of 2026, roughly a four-month window. But that grace period only protects organizations that can demonstrate genuine best effort, meaning a registered PA (a certified platform), active testing, and visible progress toward go-live. If nothing has been done, the grace period offers no protection. Expect invoice volume through the compliant channels to ramp up gradually over the coming weeks and months as more suppliers catch up, rather than a sudden full switch.
One more thing to watch: France’s tax administration has stood up a new cybersecurity unit, which will bring new security requirements for platforms. The details haven’t been published yet. This should be handled by your platform provider rather than requiring direct action from buyers or suppliers, but it’s worth confirming with your provider how they plan to respond.
Slovakia: The PEPPOL Model, With a Fun Exception
Slovakia’s mandate takes effect January 1, 2027. Under Slovak law, all B2B and B2G invoices must be electronic, with one interesting carve-out: invoices touching national security, including certain cross-border invoices, can still be issued as paper or PDF. The definition of “national security” here is broad and not yet fully clarified, so it’s worth watching how that gets interpreted.
Slovakia is implementing this through the PEPPOL network, using what it calls “digital postmen,” which is really just the standard four-corner model already used across the EU: the supplier sends to its service provider, that provider sends to the buyer’s provider, and the buyer’s provider delivers to the buyer. Slovakia adds a fifth corner for automatic government reporting, but that’s handled entirely by the PEPPOL service provider. There’s no separate integration or workflow for buyers or suppliers to build.
A few practical clarifications that came up in the episode:
- No government portal access. Unlike some countries, businesses cannot log in to a government system to view invoices. It’s purely a reporting interface between service providers and the government.
- Intercompany invoices are in scope. If two entities within the same company have different VAT numbers, those invoices fall under the mandate. This surprises more people than any other Slovakia question.
- Cross-border invoices are not in scope for reporting. A PDF invoice from a German supplier does not need to be reported in Slovakia, unlike France, Italy, or Malaysia, which do require cross-border reporting.
- No QR codes required. This is pure system-to-system exchange; there’s no human-scannable element required on the invoice image.
- Grace period: three months, financial penalties only, with the same best-efforts standard as France.
For organizations already doing e-invoicing elsewhere in the EU, this should be a lighter lift than France. Most existing e-invoice providers are already PEPPOL members, so the main task is securing a PEPPOL ID and sharing it with in-country suppliers. Existing channels for paper, EDI, or cross-border PDFs stay exactly as they are.
Norway: The Mandate Businesses Asked For
Norway’s story is genuinely unusual. Norway already has one of the highest voluntary e-invoicing adoption rates in Europe, without any mandate in place. The mandate was originally slated for 2028, but businesses, already comfortable with e-invoicing, asked the government to move it up. The government agreed.
The sequencing is also unusual compared to most of the rest of Europe. Where most mandates require receiving first and sending later, Norway is doing the opposite: as of January 1, 2027, every business must be able to send electronic invoices, and as of January 1, 2028, every business must be able to receive them. The apparent contradiction (how can sending be mandatory before receiving is) resolves this way: suppliers must send electronically once their buyer is registered in Elma, Norway’s long-standing e-invoice registry. If the buyer isn’t registered, the supplier continues sending however it does today.
One important caveat: this Elma-based mechanism is currently an informed assumption based on how the law is written, not confirmed guidance. Norway’s tax administration has been handed the job of publishing the technical details, and those guidelines haven’t been released yet, even with the mandate roughly three months out. There’s a real possibility the mechanics shift before go-live. Also worth knowing: Norway’s EHF format is simply its local branding for PEPPOL BIS, same standard, different name.
Germany: Flexible on Paper, Strict Underneath
Germany’s mandate looks deceptively simple. The law requires e-invoicing but doesn’t dictate a specific delivery method, which in theory means almost anything, even a USB stick, would technically satisfy the letter of the law. In practice, that flexibility has created real coordination challenges between trading partners who now have to separately agree on formats and transmission methods.
The timeline: buyers have already had to be able to receive e-invoices since 2025. Sending becomes mandatory January 1, 2027 for large suppliers (annual turnover over 800,000 euros), and January 1, 2028 for everyone else. Scope is domestic B2B and B2G only, with some carve-outs like transportation invoices, and B2C is explicitly out of scope, a mistake some German suppliers have already made by sending e-invoices to consumers unnecessarily.
The technical foundation is EN 16931, a semantic standard, meaning it defines what data an invoice must contain (for example, a positive-value invoice needs a due date and payment terms), not the file format itself. That semantic content then gets packaged into one of a few common formats: ZUGFeRD (a hybrid PDF with embedded XML, readable by both humans and machines, and the most widely used), XRechnung, and PEPPOL BIS.
Here’s the detail that catches AP teams off guard: in ZUGFeRD, the XML is always the legal invoice. If the PDF image and the embedded XML data disagree, the XML wins, full stop. That’s the reverse of how most AP departments are used to working, where OCR-extracted data gets corrected to match the invoice image. In Germany, it’s the other way around: the PDF is a convenient human-readable view, but the XML is the source of truth, and teams should build in a check for image-versus-data mismatches rather than assuming the visual document is authoritative.
Because there’s no single mandated delivery channel, most of the real work in Germany is upfront communication and agreement with trading partners on format and transmission, more than pure technology lift. Small suppliers should also note there’s no free government tool; some local ERPs have added basic e-invoice creation features, but it’s a cost every German business will need to plan for. Longer term, Germany is reportedly considering a reporting mandate similar to France’s, though that’s not expected before 2028 or 2029. Worth monitoring, not yet worth acting on.
Portugal: Certified Software and a Signature Requirement That Might Finally Stick
Portugal’s mandate takes effect January 1, 2027. Invoices must be issued from certified software, not just any ERP, and must carry an ATCUD code on the invoice itself.
Authenticity and integrity of invoice data must also be guaranteed, through one of three accepted routes: a qualified electronic signature (for individuals), a qualified electronic seal (for legal entities), or EDI transmission that meets specific EU regulatory requirements, not just any generic file exchange. Notably, this signature requirement has already been postponed eight times. This time is expected to be the one that sticks. In practice, suppliers will need to apply the signature, and buyers will need to be able to validate it to confirm the invoice hasn’t been altered in transit.
Spain: Three Systems, One Notice Period to Watch
Spain’s approach has three moving parts: SII (the existing tax ledger system with a portal for certain businesses), Verifactu (a certification requirement for the e-invoicing software itself, reporting to the AEAT), and the e-invoice mandate governing format and transmission.
Current planning has large businesses going live October 2027, with everyone else following in October 2028. The detail worth tracking: Spain has committed to giving at least 12 months’ notice from the final publication of the mandate. For an October 2027 go-live to hold, that publication needed to happen by around September 2026, and as of this recording, it hadn’t. There’s also discussion of unifying the three systems, which could push the timeline out further. For now, Spain belongs on the roadmap rather than the urgent list, as long as that 12-month commitment holds.
UAE: A Deadline Hiding in Plain Sight
UAE’s accreditation process was paused due to regional conflicts and has since resumed. The current expectation is a January 1, 2027 go-live for larger businesses (annual revenue around 50 million or more), with smaller businesses following in July 2027.
The detail most people miss: businesses have to formally notify the government of their chosen service provider months ahead of go-live. For larger businesses targeting the January 2027 date, that notification deadline lands at the end of October 2026, which is coming up fast. Smaller businesses have a notification deadline around the end of March 2027.
One structural requirement stands out: AP and AR must use the same service provider. Organizations can’t run one tool for sending and a separate one for receiving, which means AP and AR teams need to coordinate now on a single shared solution, especially if the October notification deadline applies to you.
UK: Early Days, But Worth Watching
The UK plans to use the PEPPOL network, which isn’t surprising given the UK’s role in helping create PEPPOL originally. A technical roadmap is expected around the end of October 2026, but the details are still being worked out. Given how central the UK is for global companies, it’s worth keeping on the radar even though there isn’t much to act on yet.
What Multinational AP and AR Teams Should Do Now
Across every country in this wave, the same three pieces of guidance hold up:
Build a list of every jurisdiction where your organization holds a registered tax ID, and track the mandate status and grace period for each one. Grace periods consistently reward organizations that can show real progress and just as consistently offer no protection to those that haven’t started. And if you already work with an e-invoice provider, lean on them; they’re tracking these mandates closely and are one of the best resources for staying ahead of what’s coming.
E-invoicing compliance has always moved in waves, from South America’s early anti-fraud mandates to the first EU adoption wave to what’s unfolding now. 2027 is simply the next one. The organizations that come out ahead are the ones treating this as an ongoing program to manage, not a single deadline to hit.
