Software for SMEs in Luxembourg: the 2026 selection grid

Search for “best SME accounting software” and you will find polished comparisons, full of figures and reasoning. None of them will help you.

Those rankings are written for markets where accounting is organised differently. In Luxembourg, four regulatory requirements immediately rule out a good share of the solutions they recommend. A tool can be excellent and strictly unusable here.

So this article offers no ranking. It sets out the compliance grid any software has to pass before anyone looks at its price or its interface.

Key takeaways

Luxembourg commercial companies must keep their accounts under the standardised chart of accounts.

Annual accounts are prepared and validated on the eCDF platform, in XBRL format, for electronic filing with the trade register.

The FAIA audit file may be requested by the authorities: the software has to be able to produce it.

Electronic invoicing runs over the Peppol network for public sector transactions.

Software that misses any of these four points will cost you the difference in manual work or accountancy fees.

The four requirements that do the filtering

The standardised chart of accounts

Luxembourg commercial companies, including SARLs, SAs and SEs, must present their accounts under the standardised chart of accounts, structured across seven account classes (Guichet.lu).

Some structures are exempt: sole traders, general and limited partnerships whose annual turnover excluding VAT stays under €100,000, and companies applying IFRS.

The direct consequence for software selection: a tool that imposes its own chart of accounts, or offers only French or Belgian ones, will have you reworking every financial year.

eCDF filing in XBRL format

Companies subject to the standardised chart must prepare and validate their accounts on the financial data collection platform before filing electronically with the trade and companies register.

The expected format is XBRL. Software that exports directly to eCDF saves you a complete re-keying of the annual accounts. Without that export, someone will re-enter the data by hand, and that someone will invoice you.

The FAIA audit file

The authorities may request a FAIA computerised audit file, Luxembourg’s equivalent of standardised audit formats. It is the point most often overlooked at selection time, and the most unpleasant to discover late: if the software cannot generate it, a routine request turns into a project.

Electronic invoicing and Peppol

Electronic invoicing is mandatory for transactions with the public sector, and travels over the Peppol network. A company working with public administrations, municipalities or public bodies has to be able to issue in the right format.

Even with no public contracts today, Peppol capability is worth checking: it is the direction of European travel, and switching invoicing software midstream costs more than choosing correctly at the outset.

What we are not doing: a ranking

It would be easy to line up five names and score them. We will not, for a simple reason: we have not tested these tools in real conditions inside a Luxembourg SME, and a ranking built from marketing pages is worth nothing.

What we can say honestly is which solutions publicly document their Luxembourg compliance. Established vendors such as Sage, BOB, SAP and Exact offer export modules compatible with eCDF, and several local solutions claim support for the standardised chart of accounts, FAIA and Peppol.

That is a starting point, not a recommendation. Compliance advertised on a sales page gets verified in a demonstration, using your own entries.

We intend to test these solutions and publish assessments based on real use. In the meantime, an honest selection grid beats an invented ranking.

The six-question selection grid

Put these to the salesperson, and ask for a demonstration rather than a verbal answer.

Question	Why it decides the matter
Is the Luxembourg standardised chart of accounts built in natively?	Otherwise, reprocessing every financial year
Is the export to eCDF in XBRL format direct?	Otherwise, full re-keying of the annual accounts
Can the FAIA file be generated?	Otherwise, a project on your hands during an inspection
Is Peppol invoicing supported?	Required for the public sector, and for what comes next
Are Luxembourg VAT rates handled, including reduced rates?	Otherwise, permanent manual corrections
Does the interface exist in your teams’ languages?	Multilingualism is not a nicety in Luxembourg

A seventh question, less technical but often decisive: does your accountant or fiduciary already work with this tool? A perfect system your fiduciary cannot handle will cost you more in fees than an adequate one they know well.

The costliest selection mistakes

Choosing on monthly price. The gap between two subscriptions runs to tens of euros. The gap between a compliant tool and one needing reprocessing runs to hours of fiduciary time, so hundreds of euros per financial year.

Trusting a “Luxembourg compatible” label. That phrase can mean nothing more than currency and VAT rate handling. Ask explicitly about the standardised chart of accounts, eCDF export and FAIA.

Migrating mid-year. An accounting software change is prepared around a year-end. Mid-year, you run two systems and two sets of entries.

Forgetting historical data. Accounting records must be kept for ten years. Check how the old system will remain consultable after migration.

And funding the change

If this choice sits within a broader modernisation effort, the Fit 4 Digital assessment covers precisely infrastructure, security and software, and its cost is fully covered by public funding.

Running the assessment before choosing avoids the classic mistake: buying a tool, then discovering it does not fit the rest of your information system.

Frequently asked questions

Can French or Belgian software work?

Sometimes, provided it explicitly includes the Luxembourg chart of accounts and eCDF export. Several Belgian vendors cover both markets. A purely French solution will generally cause problems.

Does the standardised chart of accounts apply to my small structure?

Not necessarily. Sole traders and partnerships under €100,000 in turnover are exempt. Check your situation before imposing a constraint that does not apply to you.

What is the filing deadline for annual accounts?

Filing takes place within the months following year-end, under the arrangements set out in the regulations. Have the deadline applicable to your financial year confirmed by your fiduciary, as public sources are not always current.

Do I need separate payroll software?

It depends on your headcount and the complexity of your contracts. Luxembourg payroll has its own rules, particularly around social declarations: it is an area where outsourcing remains common, including in companies otherwise well equipped.

In short

The best software for a Luxembourg SME is not the top-rated one in international comparisons. It is the one that natively handles the standardised chart of accounts, exports to eCDF, produces a FAIA file and invoices through Peppol.

Those four points get verified in a demonstration, not on a sales page. And once compliance is settled, the question that usually decides it is the most mundane one: can your fiduciary actually use it.
