Why migrate from Winbooks to Odoo in Luxembourg?
Three reasons drive a Winbooks to Odoo migration in Luxembourg in 2026: bringing accounting together with the other business flows in an integrated ERP (CRM, sales, purchasing, inventory, projects, payroll), cutting licence costs by 40 to 60% by moving to open-source Odoo.sh, and preparing ahead for the European Peppol B2B requirement for 2030. Winbooks is excellent accounting software, but it remains accounting software.
Winbooks (created in 1989) remains well established among Belgian and Luxembourg accounting firms thanks to its four versions (Classic, Connect, On Web and View), suited to different use cases. But in 2026, the need to unify tools, the Peppol B2B requirement and the arrival of native AI features in Odoo (OCR, bank reconciliation) shift the economics in Odoo's favour.

How does the migration from Winbooks → Odoo run, week by week?
A Winbooks to Odoo migration takes six weeks as standard, structured in six distinct operational stages: review and extraction (W1), Odoo configuration (W2), historical data import (W3), consistency testing (W4), team training and parallel run (W5), cutover and go-live (W6). Each week produces a deliverable signed off jointly.
Winbooks review and data extraction
Identification of your Winbooks version (Classic, Connect, On Web or View). Extraction of the n-1 trial balance, chart of accounts, legal journals, customer and supplier records, historical CODA files and fixed assets. For Winbooks Classic, access to the local SQL Server database. For the cloud versions, export via native API. Mapping to the Odoo l10n_lu PCN 2020.
Configuration of the target Odoo instance
Odoo.sh provisioning (hosted in Belgium, ISO 27001 certified), activation of the Luxembourg fiscal localization module, configuration of VAT rates 17 / 14 / 8 / 3%, purchase, sales, bank and payroll journals, fiscal positions for intra-EU reverse charge and OSS, sector modules according to business profile.
Import of historical data for 2 financial years
Import of the opening balance, 24-month general ledger, customers and suppliers with IBAN and payment terms, multi-axis analytic plan, Luxembourg bank accounts with PSD2 bank feed activation (BIL, BCEE, BGL BNP Paribas, ING, Banque Raiffeisen), fixed assets with net book values and current depreciation schedules.
Winbooks vs Odoo consistency testing
Reconciliation of totals between Winbooks and Odoo (trial balance, general ledger, sub-ledger balances, VAT balance). Test of Lux GAAP compliant invoice issuance, test of eCDF XML generation for the CTIE, test of FAIA export compliant with the AED FAIA specifications, test of bank feed and automatic matching, test of the supplier invoice approval workflow with native OCR.
Team training + start of parallel run
Three short sessions: accounting team (4h hands-on), sales and purchasing team (2h), management (1h dashboards). The parallel run starts on the last day of the week: simultaneous entry in Winbooks + Odoo, daily reconciliation by Financial Services Luxembourg. The cutover week overlaps both systems.
Final cutover and go-live
Official switch to Odoo after 30 days of stable parallel run (covering the previous week 5 and 3 pre-cutover weeks). Read-only archiving of Winbooks for the 10-year Luxembourg retention requirement. Delivery of the first monthly board pack by Financial Services Luxembourg. Official go-live signed off jointly.
How does Financial Services Luxembourg map the chart of accounts from Winbooks to Odoo (PCN 2020)?
Winbooks and Odoo both use the Luxembourg standardised chart of accounts PCN 2020 since January 2020, which makes the mapping direct for ~85% of accounts. The remaining 15% concern customised subsidiary accounts and analytic sub-accounts specific to your business, which Financial Services Luxembourg maps manually and then validates with your team before import. No account lost, no unreconciled balance.
Financial Services Luxembourg applies the official CNC 2020 correspondence tables of the Luxembourg Conseil national de la comptabilité. The Odoo Luxembourg PCN 2020 documentation serves as the technical reference. The final correspondence table is appended to the engagement letter and can be relied on with your auditors.
Which Winbooks data is carried over into Odoo, and how?
Financial Services Luxembourg carries over into Odoo all accounting and subsidiary data for the last two Winbooks financial years: opening balance, detailed general ledger, chart of accounts, customers and suppliers with bank details, fixed assets with current depreciation, VAT configuration, legal journals and historical CODA files.

What are the risks of a migration from Winbooks → Odoo, and how does Financial Services Luxembourg neutralise them?
Six typical risks of an accounting ERP migration in Luxembourg, each addressed by a contractual mitigation from Financial Services Luxembourg: lost entries (30-day parallel run), late VAT return (Winbooks remains the official system over the cutover month), team resistance (7h modular training), loss of sub-account analytics (Odoo analytic axes), budget overrun (firm fixed fee), loss of history (Winbooks read-only archive for 10 years).
Lost entries during cutover
Theoretical risk: an entry recorded during the transition is in neither Winbooks nor Odoo.
Late monthly VAT return
The eCDF return must be filed by the 15th of the following month. A delay exposes you to a minimum penalty of EUR 250.
Loss of analytic sub-accounts
Winbooks users often rely on hundreds of sub-accounts for their analytics (customer segments, product types, projects).
Winbooks team resistance
5 to 15 years of Winbooks habits (shortcuts, navigation, entry screen). An absent Champion can slow things down.
Migration budget overrun
ERP projects typically exceed their initial budget by 30 to 50% because of discoveries made along the way.
Loss of access to Winbooks history
Without access to the Winbooks history, your auditors may require a costly licence reactivation.
Our firm used Winbooks Connect for 35 client files. Financial Services Luxembourg migrated all of them to Odoo multi-company in 6 weeks. Our analytic sub-accounts became Odoo axes and our reporting became clearer.
