An ERP structures the entire management of an SME: accounting, sales, inventory, production, HR. Choosing it commits the company for 7 to 10 years and determines its ability to grow.
Key points
- Four criteria dominate the selection: functional coverage, total cost, compatibility, scalability.
- The average budget for an SME ERP ranges from 15,000 to 80,000 euros for the initial deployment.
- Odoo, Sage, Dynamics 365 Business Central and SAP Business One dominate the SME market.
- A well-implemented ERP typically delivers a positive ROI within 18 to 36 months.
Selection criteria
Functional coverage must match business processes (trading, industry, services). Integration with existing tools (CRM, CAD, e-commerce) avoids duplicate data entry. The pricing model (perpetual licence, SaaS subscription) directly impacts cash flow.
