What does an ERP cost for a Belgian SME in 2026? Pricing per segment of 10 to 50 employees

One of the first questions a Belgian SME owner asks at the start of an ERP project: what is this going to cost me? The answer they get rarely holds up. Vendors say "it depends", consultants send brochures and the numbers floating around on LinkedIn are either cherry-picked success stories or horror stories without context.

This article breaks that vagueness open and shares concrete price points per segment:

• 10 employees
• 25 employees
• 50 employees.

For each segment you get license costs, implementation costs, the 5-year Total Cost of Ownership and a typical vendor shortlist we keep seeing for Belgian SMEs in 2024, 2025 and 2026.

The numbers come from ERP projects we guided in the Benelux over recent years, supplemented with public price lists and RFP results. They are indicative, not absolute: a 25-employee services firm with one site pays less than a manufacturer with BOMs, inventory and EDI.

Why ERP prices are not transparent

Before diving into the numbers: one short explanation of why ERP pricing looks different from, say, an accounting package. Three reasons.

One: vendors sell solutions, not hours. Their revenue model is tied to licenses and to your growth over the coming years. A low entry point with strong growth afterwards is more interesting to them than a correct upfront price.

Two: price depends heavily on scope and on your processes. Two companies of the same size can differ threefold in implementation hours, depending on how well their processes are documented, how many exceptions exist and how many satellite systems need to be integrated.

Three: the Belgian market is fragmented. Between Odoo (Belgian), Exact (Dutch), SAP (German), Microsoft (American) and a dozen smaller players, the pricing logic varies. Some price per user, some per module, some per turnover or per transaction volume. This does not make comparing any easier.

With that context in mind: the three segments.

The three segments and their price zones

The table below shows the order of magnitude. The ranges are deliberately wide: a company at the bottom of the range has a simple package with little customisation and few integrations, a company at the top has the opposite.

Important nuance: the 5-year TCO is much higher than licenses plus implementation. That is operations, support, training, internal time and upgrades. Our article on ERP TCO dissects those eight categories in detail. The short version: multiply the vendor quote by 2 to 5 and you land at a realistic 5-year expectation.

Segment 1: SME of 10 employees (€2-5M turnover)

This segment buys cloud-first. Mostly SaaS packages on a monthly basis, little hardware investment, limited customisation. The typical company here has one site, one or two sales channels and a simple product range.

Licenses: €50 to €150 per user per month. The low end is a light SaaS suite like Teamleader plus Yuki or a basic Odoo. The high end is a broader package such as Exact Online or Odoo Enterprise with multiple modules.

Implementation: €15,000 to €50,000 one-off. That covers parameterisation, master data migration, basic training and at most one or two integrations (typically with a web shop or payroll). Many SMEs underestimate that a low-end implementation runs through in 6 to 10 weeks with a good vendor partner, while a messy project easily drags on for 4 to 6 months.

5-year TCO: €80,000 to €180,000. That is licenses (years 1 to 5 with indexation), implementation, roughly 5 to 8 percent of implementation in annual maintenance and a budget for 1 modern upgrade or version jump along the way.

Typical vendor shortlist for Belgium 2026:

• Odoo Community / Enterprise: strong price-quality, Belgian roots, broad module range. Watch-out: scope creep, since every module invites you to do more.
• Teamleader + Yuki: CRM-first package coupled to a strong accounting SaaS. Excellent for services and light trade, limited for manufacturing.
• Exact Online: strong in accounting plus stock management, Dutch roots but excellent BE tax integration.
• Octopus: SME accounting with a growth path. Often chosen by companies that do not really need an ERP yet but do want to move away from Excel.

Risk in this segment: you outgrow the package within 2 to 3 years and have to migrate. A low-end package costs little now but a migration to a larger system at 50-employee scale costs another €150,000-plus. Choose your entry point with your 3-year plan in mind, not your today situation.

Segment 2: SME of 25 employees (€5-15M turnover)

This segment has outgrown a first package, processes are becoming complex, and there are typically 3 to 5 satellite systems that need to be integrated such as: CRM, web shop, warehouse, planning, accounting connection. Change management becomes a real workstream.

Licenses: €80 to €200 per user per month. The difference is in modules: inventory, manufacturing BOM, project invoicing, multi-site, multi-currency. Every extra module pulls the price up by €15 to €40 per user per month.

Implementation: €50,000 to €150,000 one-off. Extra work becomes significant here. A blueprint phase of 3 to 6 weeks, configuration and customisation of 6 to 12 weeks, integrations of 4 to 8 weeks per connection, user training and data migration. Expect a lead time of 6 to 12 months.

5-year TCO: €250,000 to €600,000. This segment shows the widest spread: a services firm with simple project invoicing sits at the bottom, a manufacturer with BOM, warehouse and EDI sits at the top.

Typical vendor shortlist for Belgium 2026:

• Odoo Enterprise: strong in this segment, especially if you know you want to build integrations yourself (or via an Odoo partner).
• Exact Globe+ or Exact Online Premium: strong manufacturing and accounting functionality, Belgian tax modules baked in.
• Microsoft Dynamics 365 Business Central: a good choice if you work a lot with Office and Power Platform, strong Power BI integration out of the box.
• MKG: Belgian player focused on manufacturing and distribution, strong in BOM and planning.
• Mercator: historically strong Belgian player, especially in retail and distribution.

Risk in this segment: over-customisation. Vendors billing by the hour have little incentive to push back when you ask to code every exception in your sales process into the system. An over-customised ERP is hard to upgrade and expensive to maintain. Strong scope guarding is the most important part of your project management here.

Segment 3: SME of 50 employees (€15-40M turnover)

This segment is almost mid-market: often multi-site, sometimes international. Five to ten integrations with satellite systems. In-house IT staff or an intensive partner relationship. The difference with segment 2 lies less in package choice and more in rollout complexity.

Licenses: €100 to €250 per user per month. At the top sits a full Dynamics 365 Finance & Operations or a SAP B1 Professional. At the bottom sits a well-built-out Odoo Enterprise.

Implementation: €150,000 to €400,000 one-off for a project of 12 to 24 months, with a strong methodology (Sure Step, Activate, Odoo Implementation Methodology). Internal IT or business analysis team works alongside external integration builders for connections to existing systems.

5-year TCO: €600,000 to €1,500,000. The top of this range touches multi-site projects with international rollout. In that case expect local partners and compliance work per country.

Typical vendor shortlist for Belgium 2026:

• SAP Business One: mid-market classic, strong in multi-site and multi-currency, good industry templates for manufacturing and wholesale.
• Microsoft Dynamics 365 (BC or F&O): strong integration capabilities, Azure-native, good scalability.
• Odoo Enterprise+ with implementation partner: cost-effective for this segment, requires a strong partner relationship to keep scope in check.
• Sage X3: strong in manufacturing and distribution, especially for companies with complex supply chains.
• Infor: niche choice for specific industries like food, automotive or fashion.

Risk in this segment: duration and internal team load. A 24-month ERP rollout demands 500 to 1,000 person-days from your own team. That is a shadow budget that is rarely budgeted explicitly. And in the first 3 to 6 months post go-live most companies see a productivity dip of 15 to 30 percent.

What is not in a vendor quote?

The numbers above cover licenses, implementation and a reasonable estimate of operational 5-year costs. What a typical vendor quote does not state explicitly, and what causes budget overruns:

1. Integrations that "come later". During scoping, 2 or 3 integrations are often parked as "phase 2". In year 2 they turn out to be critical. Suddenly they are back on the roadmap with urgency and no negotiating position.
2. Customisation stacks up. Every deviation from the standard costs money at build time and again at every upgrade. An over-customised ERP slowly becomes unaffordable.
3. Internal time and change management. Project managers, key users, management and end users together spend significant time. Apply an average day rate and you find the third large amount on top of the vendor quote.

How do you select without vendor bias?

The biggest lever on your price is not the negotiation with the vendor. It is the quality of your preparation. Three actions that make the difference for our clients:

Document your processes before you request quotes. A process map with exceptions, an integration map and acceptance criteria. Only then does a vendor quote become verifiable: every line must match a documented requirement.

Request quotes from at least 3 vendors on the same scope. Not 3 quotes on 3 different visions. Three quotes on exactly the same requirements document: the difference between those quotes tells you more than any sales meeting on its own.

Add a 25 to 40 percent margin in your TCO. Even with good preparation, an ERP remains a complex project. Margin is not insurance against bad planning, it is acknowledgement that you do not fully know the future.

For those who would like these three actions guided: SEMANU works as an independent partner for the selection and blueprint phase. We have no partner relationship with any specific vendor and do not bill on overrun hours during implementation.
