How Much Does Odoo Implementation Cost in Belgium? (2026 Guide)

If you are researching Odoo implementation costs in Belgium, you have probably noticed that getting a straight answer is difficult. Most consultants and partners say 'it depends,' which is technically true but not very helpful when you are trying to build a budget.

This guide gives you real numbers based on the Belgian market in 2026. Every project is different, but these ranges will help you plan realistically and avoid unpleasant surprises.

The three cost components

Odoo implementation costs break down into three categories: software licenses, implementation services, and ongoing costs. Let us look at each one.

1. Odoo software licenses

Odoo comes in two versions. Odoo Community is open source and free. Odoo Enterprise requires a subscription. For most Belgian businesses, Enterprise is the right choice because it includes Belgian accounting features, official support, and modules like quality management and marketing automation that are not in Community.

Odoo Enterprise pricing in 2026 starts at around 24.90 euros per user per month for the standard plan, with custom pricing for larger deployments. For a typical Belgian SMB with 10 to 30 users, expect to pay between 3,000 and 15,000 euros per year in license fees depending on the plan and number of users.

Hosting is included in the Odoo Online (SaaS) plan. If you choose Odoo.sh or on-premise hosting, add hosting costs of roughly 50 to 500 euros per month depending on your server requirements.

2. Implementation services

This is the big one. Implementation services typically account for 60 to 80 percent of your total first-year cost. This includes configuration, customization, data migration, integrations, testing, training, and go-live support.

Consultant hourly rates in Belgium

Hourly rates for Odoo consultants in Belgium vary significantly depending on the engagement model.

• Official Odoo partners: 120 to 200 euros per hour. Large partners with significant overhead tend to be at the higher end.
• Independent freelance consultants: 70 to 140 euros per hour. Experienced specialists may charge more for niche expertise.
• Platforms like odoone: starting at 80 euros per hour for vetted senior consultants. This model cuts overhead while maintaining quality through screening.
• Offshore or nearshore options: 30 to 70 euros per hour. Savings on the rate can be offset by communication overhead and time zone differences.

Keep in mind that rate alone does not determine cost. A consultant at 80 euros per hour who has done 20 similar projects will work faster and make fewer mistakes than someone at 60 euros per hour who is learning as they go.

Typical project budgets by company size

These ranges represent the implementation services cost, excluding licenses. They assume standard Odoo modules with moderate customization.

Small business (1 to 10 users, 2 to 3 modules)

Typical budget: 5,000 to 20,000 euros. A basic implementation covering accounting, invoicing, and perhaps CRM or inventory can be done in 50 to 150 hours of consulting time. If your processes are straightforward and you are willing to adapt to Odoo's standard workflows, you can stay at the lower end.

Mid-size business (10 to 50 users, 4 to 6 modules)

Typical budget: 20,000 to 75,000 euros. This is where most Belgian SMBs land. You are implementing core business processes, need data migration from existing systems, require some custom reports, and have integration needs with banks, logistics providers, or e-commerce platforms. Expect 200 to 600 hours of consulting time.

Larger business (50+ users, 6+ modules)

Typical budget: 75,000 to 250,000 euros or more. Complex implementations with multi-company setups, manufacturing, advanced warehouse management, and extensive integrations. These projects require careful planning and a team of consultants. Duration is typically 6 to 18 months.

What drives costs up

Understanding what makes implementations expensive helps you control costs. These are the most common cost drivers.

1. Custom development. Every feature that Odoo does not provide out of the box requires coding. Before requesting a customization, always ask: can we adapt our process to the standard Odoo workflow instead?
2. Data migration complexity. Migrating from spreadsheets is straightforward. Migrating from a legacy ERP with years of history and inconsistent data is not. Data cleaning alone can take weeks.
3. Integration requirements. Connecting Odoo to external systems like payment providers, shipping APIs, or industry-specific platforms requires development and testing. Each integration can add 10 to 50 hours.
4. Scope creep. Starting with a clear scope and adding modules gradually is almost always cheaper than trying to do everything at once. The most expensive implementations are the ones where requirements keep expanding during the project.
5. Poor internal preparation. If your team is not available for workshops, testing, and feedback, the consultant spends more time waiting and revisiting decisions. Active participation from your side directly reduces costs.

What drives costs down

• Using Odoo standard workflows wherever possible instead of customizing to match your old way of working.
• Starting with a focused scope, perhaps two or three core modules, and expanding later.
• Having clean, well-structured data ready for migration.
• Assigning an engaged project manager on your side who can make decisions quickly.
• Choosing the right engagement model. Working with vetted independent consultants through a platform like odoone can reduce costs by 30 to 50 percent compared to large partner firms while maintaining quality.

3. Ongoing costs

Implementation is not the end. Budget for ongoing support, maintenance, and occasional enhancements. Most businesses spend between 10 and 20 percent of their initial implementation cost per year on ongoing Odoo work.

This includes bug fixes, small feature additions, user support, and eventually version upgrades. Odoo releases a new major version annually, and staying current is important for security and features. Upgrade costs vary, but expect 20 to 40 percent of the original implementation cost for a major version upgrade if you have custom modules.

How to protect your budget

A few practical strategies to avoid budget overruns.

• Get a detailed estimate with line items, not just a lump sum. You need to understand what each phase costs.
• Agree on a change management process before the project starts. How will scope changes be priced and approved?
• Insist on a phased approach. Deliver value in stages rather than waiting for a big-bang go-live.
• Start with a paid discovery or analysis phase of 20 to 40 hours. This gives both sides a clearer picture of the real scope before committing to a full project.
• Look for partners or consultants who offer satisfaction guarantees. At odoone, for example, there is a money-back guarantee and a free approval cycle, so you are not locked into something that is not working.

Bottom line

For a typical Belgian SMB implementing Odoo in 2026, plan for a first-year total cost of 15,000 to 80,000 euros including licenses and implementation. That is a wide range, but it narrows quickly once you define your scope and choose your engagement model.

The most important thing is not to find the cheapest option. It is to find the option that delivers a working system within a predictable budget. A well-implemented Odoo system pays for itself through efficiency gains, typically within 12 to 18 months. A badly implemented one just costs money forever.
