The verdict in three sentences
A custom MES for a manufacturing SME costs between 50,000 and 140,000 EUR in 2026, versus market solutions at 500 to 3,000 EUR/month depending on stations and modules. Custom is the right call when shop-floor tracking, traceability and performance indicators (OEE) must fit your routings and connect your machines. Budget 6 to 9 months of development, with ROI driven by 10-20% productivity gains.
What an MES manages
An MES handles work orders, real-time shop-floor tracking, time and quantity reporting, lot/serial traceability and performance indicators (OEE). In 2026, direct machine connectivity (PLCs, sensors) collects data without manual entry.
| Module | Custom | Market solution |
|---|---|---|
| Work orders | Your routings | Standard |
| Real-time shop-floor | Tailored | Varies |
| Lot/serial traceability | Complete | Standard |
| OEE indicators | Your formulas | Predefined |
| Machine connectivity | Native | Often an add-on |
| Code ownership | 100% yours | None |
Build vs buy: 3-year cost
A market MES starts faster but imposes its models; custom becomes relevant when your production processes are specific and machine connectivity matters.
| Scenario (10 stations) | Custom | Market MES 1,800 EUR/month |
|---|---|---|
| Upfront investment | 95,000 EUR | 0 EUR (+ integration) |
| Monthly cost | ~900 EUR (hosting + maintenance) | 1,800 EUR |
| Recurring annual cost | ~10,800 EUR | 21,600 EUR |
| 3-year total | ~127,400 EUR | ~64,800 EUR + integration |
| Machine connectivity | Native | Often extra |
| Ownership + extensibility | Full | None |
The market MES wins on raw 3-year cost; custom wins when your routings, traceability and indicators are specific, and machine data must flow in automatically.
Mini case study
Marc, director of a manufacturing SME in Berlin (10 stations, 8M EUR revenue, 62% OEE), ran production on spreadsheets. With a custom MES at 95,000 EUR, machine connectivity and real-time tracking raise OEE to 74% (+12 points), i.e. additional capacity worth ~640,000 EUR/year, while removing ~12 hours/week of data entry and reporting. Payback in under 6 months.

How much does a custom MES cost in 2026?
Between 50,000 and 140,000 EUR depending on modules (work orders, shop-floor tracking, traceability, OEE, machine connectivity). A useful base starts around 60,000 to 80,000 EUR.
Can it connect to our existing machines?
Yes: a custom MES can connect to PLCs and sensors (OPC UA, Modbus, etc.) to collect times, quantities and stoppages without manual entry.
How is OEE calculated?
Per your formulas and stoppage rules: availability, performance and quality are combined, with indicators per station, shift or product tailored to your shop floor.
What is the implementation timeline?
Between 6 and 9 months, with a first version (work orders + shop-floor tracking) usable in 12 to 16 weeks.
Does an MES really improve productivity?
Yes: by making stoppages and bottlenecks visible, it delivers typical OEE gains of 10 to 20%, often the line item where the investment pays for itself fastest.
