Odoo has published its 2025 financial results: €619 million in billed sales and €480 million in ARR (Annual Recurring Revenue), maintaining a 57% annual growth rate sustained over the past decade. In Europe, Q1 2026 figures reveal particularly strong momentum in the Benelux region, with Belgium leading at +70% growth (Much Consulting, April 10, 2026).
Belgium Leads European Growth
Q1 2026 regional data reveals a contrasted landscape of Odoo adoption across Europe:
- Belgium: +70% — Odoo’s home market significantly outperforms
- Baltic States: +68% — an emerging corridor for open-source ERP
- Germany and Austria: +66% — significant breakthrough in the Germanic industrial market
- Netherlands: +49%, Nordics: +48% — solid growth in highly digitized markets
- France: +29%, Italy: +25% — more modest progress in Latin markets
- UK/Ireland: +7% — near-stagnation, reflecting the maturity of the Anglo-Saxon market
The contrast is striking: Benelux and DACH regions are pulling the locomotive, while Southern Europe shows decline (-11% in Southern Europe) (Much Consulting).
Why Belgium is Taking Off
Three factors explain this Belgian outperformance.
The Partena Professional effect. The partnership announced in early April 2026 between Odoo and Partena Professional — Belgium’s second-largest social secretariat handling 920,000 payslips monthly — is the largest contract in Odoo’s history. The launch is scheduled for January 1, 2027. This signal has mechanically strengthened Odoo’s credibility among large Belgian enterprises.
The cloud shift. 79.9% of Odoo customers now use a cloud offering (47.9% on Odoo Online, 32% on Odoo.sh). The highly digitized Belgian market naturally accelerates this trend, especially as electronic invoicing becomes widespread across Europe.
The local ecosystem. Odoo, based in Louvain-la-Neuve, benefits from a dense network of implementation partners in its domestic market. With 6,800 employees and a target of 3,000 new hires in 2026 — one-third in Belgium — the publisher is strengthening its local deployment capacity.
What This Changes for European CIOs and CFOs
For Benelux companies, these results confirm that Odoo is no longer a niche ERP for SMEs. The traction in the payroll/HR segment with Partena and double-digit growth in mature markets (Germany, Nordics) repositions the Belgian publisher against SAP Business Central, Microsoft Dynamics 365, and Unit4 in the mid-market competition.
For international companies, the opening of a new office in Lyon on June 1, 2026 with 80 planned hires by year-end is a concrete signal. Odoo anticipates mandatory electronic invoicing regulations across Europe and strengthens its field presence beyond major capitals (Much Consulting).
What to Watch
The challenge for Odoo in 2026 will be converting this commercial growth into long-term retention. With 14% of customers still on unsupported versions and a growth rate that significantly weakens in Southern Europe and the UK, the next step will be proving that hypergrowth in Belgian and Germanic markets translates to retention — not just acquisition.
