As electronic invoicing gains momentum across Europe, Peppol is increasingly emerging as the backbone of structured invoice exchange. In Luxembourg, where cross-border activity and multilingual entrepreneurship are the norm, the transition raises specific questions around readiness, accessibility and timing.
Since March 2023, electronic invoicing has been mandatory for all economic operators issuing invoices to Luxembourg public authorities. These invoices must comply with the European e-invoicing standard and are typically exchanged via the Peppol network. Outside the public sector, however, Peppol adoption remains voluntary, and no official roadmap has yet been published for a broader business-to-business mandate.
This limited scope should not be mistaken for a lack of urgency. In practice, many Luxembourg companies are still far from Peppol-ready. SMEs in particular continue to rely on PDFs and email-based invoicing workflows that are incompatible with structured e-invoicing requirements.
“The biggest obstacles are lack of awareness and a structural information gap in the market,” says Marysia Dabrowska, co-founder of eFaktura, a multilingual e-administration platform that connects directly to Peppol. “We see a remarkable level of unawareness — not only among entrepreneurs, but also among their accountants. Many receive little to no concrete guidance about Peppol, timelines or practical steps.”
According to Dabrowska, these blind spots mirror Belgium’s experience, where communication campaigns started too late and preparation became “rushed and reactive instead of planned.”
Information gaps and fear of complexity
While the technical side of Peppol is often manageable, the perception of complexity remains a major deterrent. “A surprising number of companies still create invoices in Word or Excel and assume Peppol will be extremely complex or expensive for them,” Dabrowska notes. “In reality, it does not have to be — but without clear explanations and accessible tools, it feels overwhelming.”
The result is a cycle of hesitation: entrepreneurs delay preparation, expecting postponements, and eventually face last-minute panic once deadlines approach. In Poland, where a similar structured invoicing system (KSeF) becomes mandatory this year, Dabrowska reports that many SMEs are still “hoping it will be postponed,” despite months of official communication. “During the final days before the new year, our customer support effectively functioned as a hotline — continuous onboarding requests, urgent questions and last-minute stress. This situation was entirely avoidable.”
Lessons from Belgium — and beyond
Developments in neighbouring countries continue to offer a mirror for Luxembourg. Belgium’s phased rollout of mandatory B2B e-invoicing via Peppol revealed how critical early preparation is — and how much confusion can result from limited communication between accountants and clients.
“Many accountants in Belgium created Peppol connections on behalf of their clients without properly informing them,” Dabrowska recalls. “Entrepreneurs were often unaware that their Peppol inbox was effectively hosted by their accountant, that they were now technically bound to that setup, and that switching to another software solution was no longer straightforward.”
Such experiences underline a key lesson: creating a Peppol connection is not enough. Structured e-invoicing changes the entire invoicing process, not just the delivery channel. “Without proper education, entrepreneurs don’t fully understand what Peppol means in practice. Readiness is not just about software — it’s about ownership, transparency and informed choice,” she stresses.
Belgium’s pragmatic enforcement approach — gradual rather than punitive — helped limit disruption, but it also exposed the need for clarity. For Luxembourg companies, the main takeaway is that Peppol should empower entrepreneurs, not lock them into opaque setups they do not understand.
Language: the missing layer of compliance
Luxembourg’s highly international business environment adds another layer of complexity. Entrepreneurs operate in a wide range of languages, reflecting the country’s diverse workforce and cross-border economic ties. Yet most invoicing and accounting platforms remain available only in one or two languages, increasing the risk of misinterpretation and non-compliance for foreign-language users.
“Language determines trust,” Dabrowska says. “When communication, tools and legal explanations are available only in one language, entrepreneurs become hesitant — not because they are unwilling to comply, but because they are unsure whether they truly understand what is expected of them.”
This linguistic gap can also distort relationships between entrepreneurs and their accountants. “In some cases, accountants do not proactively share information with non-native clients because of language barriers, or they set up a Peppol connection without proper explanation. Entrepreneurs then find themselves using a system they don’t understand, which creates frustration and resistance. It’s not unwillingness — it’s exclusion.”
The lesson, she insists, is simple: multilingual communication is not a luxury but a compliance necessity. “Legal changes must be explained repeatedly, clearly and in the right language to build understanding and confidence.”
eFaktura and the rise of multilingual compliance platforms
It is precisely this multilingual challenge that gave rise to eFaktura. Originally launched in the Netherlands for international entrepreneurs, the platform now supports Peppol-compliant invoicing in ten languages, including English, French and German. It automates the entire e-invoicing flow — from VAT validation to secure transmission via a certified access point — and integrates broader administrative functions such as expense management and customer billing.
“eFaktura was created for entrepreneurs who operate beyond one country and one language,” Dabrowska explains. “From the beginning, the goal was to remove administrative friction for international SMEs by offering legally compliant invoicing per country, clear guidance in the user’s own language, and one platform that evolves with regulatory changes across Europe. Multilingualism was not an add-on — it was the foundation.”
The company’s ecosystem also links to BUKKI, a platform that helps self-employed professionals collaborate and find assignments in their own language. Together, these services reflect a broader trend: digital tools are no longer standalone utilities but part of integrated compliance ecosystems combining regulatory alignment with day-to-day usability.
The timing question
For now, Luxembourg has adopted a cautious, phased approach to Peppol implementation, focusing primarily on public procurement. Yet with several EU member states — including France, Germany, and Poland — moving toward mandatory B2B e-invoicing, a broader European alignment is inevitable.
At EU level, Peppol is increasingly seen as a cornerstone of future tax and reporting frameworks. The European Commission’s “VAT in the Digital Age” (ViDA) initiative aims to harmonize e-invoicing and real-time reporting across member states, potentially accelerating adoption even in markets that have so far remained voluntary.
In this evolving context, waiting may prove costly. “In practice, companies often start preparing only one or two months before an obligation begins — far too late,” Dabrowska warns. “Early preparation allows time to test, train staff, and choose the right setup without pressure. That calm phase is what makes implementation successful.”
Readiness as strategy
The experience across Europe suggests that readiness is not just about compliance, but competitiveness. Firms that adopt structured invoicing early benefit from cleaner data, faster payments, and smoother accounting integrations. Those that delay risk administrative disruption once mandates expand.
In Luxembourg’s multilingual and highly international economy, these dynamics are amplified. Accessibility and usability may prove just as critical as regulatory alignment — especially for small and medium-sized enterprises that lack in-house compliance resources.
As Dabrowska concludes: “Start now, choose software you truly understand, and treat Peppol as a business change — not a last-minute IT obligation.”
