The best accounting software for Luxembourg in 2026

Short answer

Two packages document their Luxembourg obligations in public. Odoo Accounting names PCN 2020, eCDF XML at all three filing frequencies, a FAIA export and Peppol BIS Billing 3.0, and charges 24.90 euros per user per month on annual billing. Exact WinBooks confirms the Luxembourg chart of accounts adapted from 1 January 2020, eCDF XML for the periodic return, the recapitulative statement and the official balance sheet, and a FAIA module, from 67 euros a month excluding VAT. If you are a small fiduciaire, Horus is the cheapest readable entry at 52.50 euros a month including fifteen client files.

How we tested accounting software against Luxembourg, not against features

A feature list is not compliance. Five questions decide whether a package works here, and they are the only things this ranking scores.

Does it export the VAT return as eCDF XML? Luxembourg has two tax administrations and they are not interchangeable. VAT belongs to the Administration de l'enregistrement, des domaines et de la TVA, and since 1 January 2020 every VAT return and recapitulative statement must be filed electronically through eCDF. Direct taxes belong to the Administration des contributions directes, which runs its own channels for the corporate income tax return, and none of the eight packages claims to file that one for you.

Can it produce a FAIA file, and in which schema? On request during an inspection you hand over an XML audit file, one per financial year. The schema matters: the AED assigns the full schema to an integrated accounting and commercial management system, reduced version A to accounting plus an invoicing module, reduced version B to accounting alone. See FAIA export, what it is and who needs it.

Does it carry the PCN 2020 chart of accounts? Most commercial companies must present their balance under the plan comptable normalisé, whose current content applies to financial years from 1 January 2020. Sole traders, SENC and SCS under 100 000 euros of turnover excluding VAT are outside it.

Does a Luxembourg fiduciaire actually work in it? The softest criterion and often the most expensive. If nobody local will open your file, you are paying for retyping.

Is it available in French and German? Three of the eight have no German interface and one has no French one. We also score disclosure: a vendor that publishes a price and names its Luxembourg outputs can be held to both.

The three mistakes that cost Luxembourg buyers money

Buying a VAT rate per sale instead of per article. The Luxembourg rate attaches to the goods or the service, not to the customer or the place of consumption, so one restaurant bill can carry 3, 14 and 17 percent at once. Which VAT rates apply in Luxembourg sets out the annexes. Worth knowing before you shop: not one vendor in this comparison prints the 17, 14, 8 and 3 percent set in its product documentation. The only place we found them written out was an Intuit tax reference page that makes no product claim at all.

Treating electronic invoicing as one thing. Luxembourg has required a compliant electronic invoice to public bodies through Peppol or MyGuichet.lu since 18 March 2023, for every operator regardless of size. A package that generates an XRechnung file has solved a format, not a delivery. Our invoicing comparison separates the three meanings vendors blur.

Paying today for a 2028 promise. Bill 8815, deposited on 30 July 2026, transposes article 1 of Council Directive (EU) 2025/516 and enters into force on 1 January 2028, with issuing obligations by 1 July 2028 for issuers exceeding at least two of 7 500 000 euros of balance sheet total, 15 000 000 euros of net turnover or 50 full time employees at their 2026 balance sheet date, and by 1 January 2029 for the rest. It is still a bill. Get the commitment into the contract, not into the price.

The ranking

1. Odoo Accounting, 24.90 euros per user per month

Odoo's documentation names the Luxembourg localisation modules, the PCN 2020 chart of accounts, the 17, 14, 8 and 3 percent tax set, XML exports of the monthly, quarterly and annual VAT returns for eCDF, FAIA generation from the general ledger report, and Peppol BIS Billing 3.0. No other vendor publishes that depth. The price is public too: a One App Free tier, Standard at 24.90 per user per month on annual billing and Custom at 44.90, with a 19.90 promotion visible on 11 November 2026. What is not on the pricing page is the implementation partner and the data discipline a clean FAIA export needs. Per user pricing is also the wrong shape for a practice with many client files.

2. Exact WinBooks, from 67 euros a month excluding VAT

The Belgian WinBooks ledger, Exact owned since December 2019 and sold into Belgium and Luxembourg through resellers. Its own help portal is where the Luxembourg substance lives, and it is specific: the Luxembourg chart of accounts adapted from 1 January 2020, XML generated for periodic VAT returns, recapitulative statements and the official balance sheet, and a separate FAIA module. Indicative prices are published, from 67 euros a month for a one person business, 121 for an SME and 180 for a fiduciaire with unlimited client files, all excluding VAT.

Three things to raise with the reseller. The help portal says only FAIA 2.01 reduced version B is available, which is the schema for accounting without integrated invoicing, so ask which schema applies if you also run the commercial management module. The same portal documents that CODA bank file import, XML VAT grouping and the lettre TVA do not work on a Luxembourg legislation file. And two vendor pages price the same entry card at 42 and at 67 euros a month, so get the number in writing. There is no German interface.

3. Horus, from 52.50 euros a month including fifteen client files

Built for Belgian and Luxembourg fiduciaires, cloud native, and the cheapest entry in this group that you can price without a phone call. The Luxembourg page is specific where it counts: FAIA, periodic and annual VAT returns, the recapitulative statement, and bank statement import by format with MT940 and CAMT.053 named rather than implied. A separate client facing app covers Peppol e-invoicing and document sharing. Two honest problems. Activation fees are excluded from the published price and never quantified, and the vendor's own Luxembourg page dates mandatory e-invoicing to January 2027, which does not match the bill now before parliament. The interface is French and Dutch, with no German evidenced.

4. Sage BOB, price on request

BOB, formerly Sage BOB 50 and sold to practices as Sage BOB Expert, is what a large share of Luxembourg fiduciaires run. Sage's product page claims compliance with Belgian and Luxembourg legislation and filing annual accounts with the eCDF, its own BOB 50 help portal documents a FAIA export, and House of Training teaches it in Luxembourg with PCN 2011 and PCN 2020 and XML balance sheet filing on the advanced syllabus.

What holds it to fourth is what Sage does not say. There is no commercial price anywhere; the only published figure is an indicative trainee rate, 821 euros a year for Luxembourg trainees, capped at 20 client files and basic accounting. There is no Sage Luxembourg site, the country is served from the Belgian one. Sage's own documentation refers to the 2011 standard chart of accounts, and no Sage page we have seen claims PCN 2020. And the eCDF evidence we found covers annual accounts, not the VAT return. If your fiduciaire runs BOB, the handover saving probably outweighs all of it, but ask for a FAIA file from a demo database and written confirmation that the current release carries PCN 2020.

5. Exact Online, from 49 euros a month excluding VAT

The clearest price list in this comparison: Essentials at 49 euros a month excluding VAT for one user, one ledger and 25 sales invoices, then 99, 159 and from 299, with a 30 day trial most packages in this class do not offer. It is here to answer a frequent question, and the answer is no. There is no Luxembourg division, the accounting pages mention neither Luxembourg nor FAIA nor eCDF, and Exact describes its own market as the Netherlands, Belgium and Germany. The Luxembourg capable product here is WinBooks.

6. Zoho Books, 10 euros per organisation per month

Real euro pricing, Standard at 10 euros per organisation per month on annual billing and 12 monthly, with a free plan below it and a 14 day trial. Priced per organisation rather than per user, which makes it the cheapest competent ledger here for a small team, and both French and German interfaces are supported. As Luxembourg software it does not exist: no Luxembourg edition, no FAIA, no SAF-T, no eCDF, no PCN, and tax rates are user defined so the four Luxembourg rates have to be built by hand. The telling detail is that Zoho ships country compliance when it chooses to, SKR 03 and SKR 04 charts with a DATEV export for Germany and Peppol for Belgium and Spain. Luxembourg simply was not worth it to them.

7. QuickBooks Online, from 23 euros a month

Genuinely sold in Luxembourg, which surprises people, and genuinely billed in euros through Intuit's Rest of Europe billing region: 23, 34, 52 and 83 euros a month across four tiers, with a 30 day trial that you have to choose instead of the promotional discount. There is no Luxembourg country site. More to the point, Intuit's own list of countries with prefilled tax rates runs to twenty two entries and contains no EU member state, so 17, 14, 8 and 3 percent are yours to enter, and no FAIA, eCDF or PCN 2020 function is documented. The global product also has no French interface, only German among the European languages. Intuit withdrew QuickBooks from France on 31 December 2023, which is worth weighing before you commit European books to it.

8. Pennylane, from 7 euros a month excluding VAT

A strong French platform built on the right idea, the company and its expert-comptable in one file, with published prices from 7 euros a month excluding VAT and a 15 day trial. It is last because the disqualification comes from the vendor: Pennylane's help centre states that the platform handles French accounting only and does not support the accounting or tax returns of a foreign entity, and its legal notice lists France, Germany and Spain as its markets. Excellent in France, unusable as a Luxembourg ledger.

What we left out, and why

Microsoft Dynamics 365 Business Central. Microsoft's own table lists Luxembourg as partner localised on the international W1 base app, Luxembourg is absent from the Microsoft led European localisations, and a search of Microsoft's documentation for FAIA returns nothing. Any Luxembourg capability comes from a third party app we could not verify, on top of 69.30 euros per user per month excluding VAT on the French price list.

Cegid Loop and Cegid Quadra. No Luxembourg site, no published price, and a site search returning nothing for FAIA, eCDF or plan comptable normalisé.

Luxembourg specialist complements. Tools that sit beside a ledger and produce annual accounts, eCDF filings and tax forms from a trial balance. A Luxembourg distributor we read sells one alongside Sage BOB. If your pain is the annual accounts rather than the daily postings, ask your fiduciaire which complement they already use.

Which one should you buy?

A company that wants one system for sales, stock and the ledger with a documented FAIA export should buy Odoo and budget the partner. For a Benelux package with Luxembourg support written down by the vendor, shortlist Exact WinBooks and settle the FAIA schema question first. A small fiduciaire should trial Horus, the only one that quotes from a web page. If your accountant already runs BOB, run BOB and spend the saved argument on written exit terms. Under the PCN threshold with a handful of transactions, Zoho Books is honest value.

Whatever the shortlist, read the five questions to ask your fiduciaire before the demo, not after. And if you publish one of these packages and we have a fact wrong, or you want to supply the price your own site does not show, the route is get listed.
