The verdict in three sentences
An IT roadmap for an industrial SME costs between 85,000 and 200,000 EUR over 2-3 years: ERP core, differentiating custom modules and IoT integration. The key isn't the total but prioritization by ROI: deploy first what pays back fastest. With grants (public innovation funding, tax credits) and good change management, productivity gains 15 to 25%.
The 2026 budget structure
A digitalization budget splits into three main masses, spread over several fiscal years.
| Item | Scope | 2026 range |
|---|---|---|
| ERP core | Management, purchasing, sales, accounting | 40,000-90,000 EUR |
| Custom modules | Where you are differentiating | 30,000-70,000 EUR |
| Integration / IoT | Machines, sensors, exchanges | 15,000-40,000 EUR |
| Change management | Training, support | 8,000-20,000 EUR |
| Annual maintenance | ~15-20% of build | 15,000-35,000 EUR/yr |
Stacking these items without prioritization leads to a tunnel project. Better to sequence in 4-to-6-month waves, each producing a measurable result.
Grants and ROI prioritization
2026 funding schemes significantly reduce the net cost of an Industry 4.0 project.
| Scheme | Nature | 2026 order of magnitude |
|---|---|---|
| Public innovation grants | Subsidy / loan | up to 40-50% of the base |
| National industry programs | Co-financing | per call for projects |
| Innovation tax credit | Tax reduction | 20-30% of eligible spend |
| Equipment accelerated depreciation | Tax deduction | per investment |
Combining a subsidy and a tax credit, the real net cost of a 120,000 EUR project can drop well below 80,000 EUR, to be validated with your accountant.
Mini case study
Claire, CFO of a 60-employee industrial SME in Lyon (14M EUR revenue), builds a 3-year roadmap. Wave 1: ERP core at 62,000 EUR. Wave 2: scheduling + stock modules at 45,000 EUR. Wave 3: machine IoT at 28,000 EUR, i.e. 135,000 EUR. With 45% of grants and tax credit combined, net cost falls to ~78,000 EUR. An 18% productivity gain on a 2.1M EUR productive payroll represents ~378,000 EUR/year of value created: the project pays back within the first full year.

FAQ
Where to start industrial digitalization?
With the ERP core and the item that pays back fastest (often stock or scheduling). Prioritize each wave by measurable ROI rather than usage comfort.
Which grants to tap in 2026?
Public innovation grants, national industry programs and the innovation tax credit. Combined, they often cover 30 to 50% of the eligible base, to confirm for your situation.
How much to budget for maintenance?
Expect 15 to 20% of development cost per year, i.e. 15,000 to 35,000 EUR/year for a full project. Budget it from the start.
Is change management really necessary?
Yes. Without training and support (8,000-20,000 EUR), adoption fails and the ROI never materializes, whatever the tool deployed.
Do I need a single vendor for everything?
Not necessarily, but a single integrator for core plus custom modules limits interface friction and clarifies responsibility when bugs arise.
