Odoo configuration for Luxembourg:
what blocks it, and how we unblock it.

Odoo installs in a few minutes. What takes time is making it correct under Luxembourg law: PCN 2020 standard chart of accounts, VAT fiscal positions, statutory journals, bank connection, analytic plan, eCDF and FAIA reports. This page details what to configure, in what order, and what that means in actual hours.

Question 01

What needs to be configured in Odoo for a Luxembourg company?

Six blocks make accounting usable: the PCN 2020 standard chart of accounts, the four VAT rates with their fiscal positions, statutory journals, the PSD2 bank connection, the analytic plan, and the eCDF and FAIA filing reports. An incomplete configuration produces entries that look correct on screen but become unusable at year-end closing or in an inspection.

Chart of accounts PCN 2020

01

Activation of the Luxembourg localisation module, loading of the standard chart, creation of sub-accounts specific to your business and definition of the default counterpart accounts for each product and expense family.

  • l10n_lu module
  • Standard chart
  • Sub-accounts
  • Default accounts
  • Counterparts
  • Financial year

VAT and fiscal positions

02

Four Luxembourg rates, plus automatic substitution rules based on the customer profile: taxable person in another Member State, private individual in the EU, customer outside the EU. This is the block where the costliest errors concentrate.

  • 17, 14, 8 and 3%
  • Reverse charge
  • Export exemption
  • OSS scheme
  • Fiscal positions
  • VAT accounts

Statutory journals

03

Sales, purchase, bank, cash, miscellaneous operations and payroll journals, each correctly typed and linked to its numbering sequences. A wrongly typed journal produces incorrect financial statements without any error message.

  • Sales and purchases
  • Bank and cash
  • Miscellaneous operations
  • Payroll
  • Sequences
  • Period locking

PSD2 bank connection

04

Automatic synchronisation with the banks of the Luxembourg market, then configuration of reconciliation rules so that recurring payments match on their own. Availability per institution is checked at configuration time.

  • BIL
  • BCEE
  • BGL BNP Paribas
  • ING Luxembourg
  • Raiffeisen
  • Reconciliation rules

Analytic plan

05

Tracking axes by activity, project, site or product line. To be configured before go-live: an analytic axis created after six months of operation leaves six months of entries without allocation, which nobody ever goes back to fix.

  • Multiple axes
  • Auto distribution
  • By project
  • By site
  • By activity
  • Cross reports

eCDF and FAIA reports

06

Generation of the VAT return in the format expected by the eCDF platform, and of the FAIA export compliant with the AED FAIA specifications. This block is dry-run tested before the first real deadline, never the day before filing.

  • VAT return
  • eCDF format
  • FAIA export
  • Auditors' balance
  • General ledger
  • Dry runs
Question 02

The 6 configuration errors we correct most often.

These six errors share one characteristic: they trigger no warning message and are not visible in daily use. They surface at the time of the VAT return, the annual closing or an inspection, that is, at the worst moment and at the highest cost of retroactive correction.

Missing or wrongly assigned fiscal positions

A German taxable customer receives an invoice at 17% instead of reverse charge. The error goes unnoticed until the return, then credit notes must be issued and the invoices reissued.

FixCreation of fiscal positions by zone, automatic assignment on the customer record, check on a sample of existing invoices.

Default counterpart accounts not defined

All sales land on a generic account and the income statement becomes unreadable. The analytic restatement at closing then takes several days.

FixDefinition of accounts by product and expense category, restatement of the current financial year's entries.

Wrongly typed journals

A miscellaneous operations journal used as a bank journal distorts the bank reconciliation and the cash flow presentation, without any error message.

FixRetyping of journals, restoration of sequences, consistency check on the period concerned.

Analytic plan created after the fact

The axes are set up after six months of operation. Earlier entries remain unallocated and the first analytic report covers an incomplete half-year.

FixRetroactive allocation through distribution rules, where volumes allow. Otherwise, a clean restart on a fixed date.

eCDF and FAIA reports never tested

Generation is discovered the day before the deadline. A missing field on the third-party records blocks the export and the return is filed late, with the corresponding penalty.

FixDry-run test from the configuration stage, check of mandatory fields across all third-party records before the first deadline.

Accounting periods not locked

An entry is posted to a financial year that has already been filed. The trial balance no longer matches the published annual accounts and the difference must be justified to the auditors.

FixLocking of closed periods, definition of unlocking rights, documented correction procedure.
Question 03

How many hours does a full Odoo configuration take?

Between nineteen and thirty-one hours for a standard SME, data migration included. That is precisely why we offer a fixed fee of €3,900 excl. VAT in the Business pack rather than hourly billing: at €150 per hour, the low end would already come to €2,850 and the high end to €4,650. The fixed fee protects you against overruns, not us.

QUESTION 04

Already have an Odoo instance and something is wrong?

We take over instances configured by others, and it is a significant part of our business. The method is constant: read access to the database, a findings report listing anomalies by order of severity, costing of the fix. The findings report is not charged when it leads to an engagement. We do not sign a quote without having seen the database: technical debt is not something to discover after signing.

Question 06

Odoo configuration FAQ in Luxembourg

Eight questions marked up with FAQPage Schema.org, focused on the configuration points that have a direct accounting effect.

What needs to be configured in Odoo for a Luxembourg company?+
For a Luxembourg company, six blocks must be configured in Odoo: the PCN 2020 standard chart of accounts, the four VAT rates with their fiscal positions, statutory journals, the PSD2 bank connection, the analytic plan, and the eCDF and FAIA reports. An incomplete configuration produces entries that are correct on screen but unusable at closing or in an inspection.
How much does Odoo configuration cost in Luxembourg?+
Odoo configuration in Luxembourg costs €150 excl. VAT per hour at FSL, in blocks of two hours minimum and with no commitment. Since a full configuration with data migration represents nineteen to thirty-one hours, the fixed fee of €3,900 excl. VAT is more advantageous beyond twenty-six hours. A full configuration with migration represents 19 to 31 hours, which justifies the fixed fee of the Business pack at €3,900 excl. VAT rather than hourly billing. Hourly sessions suit targeted corrections on an instance already in service.
Can you configure Odoo yourself?+
Configuring Odoo yourself is realistic for the visible part, products, customers, document templates and users, much less so for the accounting part. The costliest errors concern fiscal positions, counterpart accounts and journal typing. Much less so for the accounting part. The errors we correct most often concern wrongly assigned fiscal positions, default counterpart accounts, wrongly typed journals and analytic axes created after the fact. They are not visible in daily use.
How long does a full Odoo configuration take?+
A full Odoo configuration takes nineteen to thirty-one hours for a standard SME: four to six hours for the chart of accounts, VAT and journals, six to ten hours for the migration of the trial balance and general ledger, then customers and suppliers, fixed assets, banking and training.
What is a fiscal position in Odoo?+
A fiscal position in Odoo is a rule that automatically substitutes a VAT rate and account according to the customer profile: Luxembourg company, taxable person in another Member State, private individual in the EU or customer outside the EU. It triggers reverse charge or exemption without intervention. Correctly configured, it applies reverse charge or exemption without intervention. Incorrectly configured, it charges 17% to an intra-EU customer and distorts your entire return.
Does Odoo connect to Luxembourg banks?+
Odoo connects to Luxembourg banks through PSD2 bank synchronisation, which covers the main institutions in the market. It removes manual file imports and enables automatic reconciliation of recurring payments. The main institutions in the market are covered, including BIL, BCEE, BGL BNP Paribas, ING Luxembourg and Banque Raiffeisen. Synchronisation removes manual file imports and enables automatic reconciliation. Availability per institution may vary and is checked at configuration.
Does the configuration have to be redone at every version upgrade?+
Redoing the configuration at every version upgrade is not necessary: it is kept during standard updates. However, a new version may make some earlier workarounds obsolete, and third-party modules must be checked. The configuration is kept during standard version upgrades. However, a new version may make some earlier workarounds obsolete, and third-party modules must be checked. FSL performs a consistency check after each major version upgrade on the instances it follows.
Can you correct a configuration done by someone else?+
Correcting an Odoo configuration done by someone else is a significant part of our business: read access to the database, a findings report ranking anomalies by severity, then costing of the fix. The findings are not charged if they lead to an engagement. Read access to the database, findings report listing anomalies by severity, then costing of the fix. The report is not charged when it leads to an engagement. The most frequent corrections concern intra-EU VAT and default counterpart accounts.

Configuration is not enough if nobody knows how to use it.

A perfectly configured instance that is poorly mastered produces the same errors as a poorly configured one. Our training page details the content by role, the actual duration needed and what makes a session effective.
