The verdict in three sentences
If 80 % of your processes match your sector, an off-the-shelf vertical ERP saves months and de-risks the project. If your competitive edge rests on atypical flows the standard cannot model, custom protects your differentiation. The real trade-off is not price alone, it is standardisation versus flexibility, and speed versus control.
Two models, two cost structures
A vertical ERP delivers 70 to 90 % of a sector's needs immediately, with recurring licences. Custom starts from your real process, with no licence but a longer timeline. 2026 orders of magnitude for an Amsterdam industrial SME:
| Item | Vertical ERP | Custom development |
|---|---|---|
| Licence / user / month | EUR 50 to 150 | EUR 0 |
| Implementation | EUR 30,000 to 120,000 | included in the build |
| Build | — | EUR 100,000 to 300,000 |
| Deployment time | 4 to 6 months | 8 to 14 months |
| Native sector coverage | 70 to 90 % | 100 % targeted |
| Evolution flexibility | medium | total |
| Vendor lock-in | high | none |
Costed decision grid
Compare a vertical ERP at EUR 90/user/month (EUR 80,000 implementation) for 30 users, against custom at EUR 180,000, EUR 30,000/year maintenance, over five years.
| Year | Vertical ERP (cumulative) | Custom (cumulative) |
|---|---|---|
| Year 1 | EUR 112,400 | EUR 210,000 |
| Year 2 | EUR 144,800 | EUR 240,000 |
| Year 3 | EUR 177,200 | EUR 270,000 |
| Year 4 | EUR 209,600 | EUR 300,000 |
| Year 5 | EUR 242,000 | EUR 330,000 |
At 30 users, vertical stays cheaper over five years. But two factors flip it: user count (at 60 users vertical passes EUR 400,000) and the cost of non-standard customisations, often billed EUR 800 to 1,500/day by the vendor.

Mini case study
Helene, industrial director of a food plant in Amsterdam, equips 42 people. A vertical food ERP at EUR 100/user/month costs her EUR 50,400/year, so EUR 252,000 over five years plus EUR 90,000 implementation: EUR 342,000. But her batch traceability and bespoke scheduling need 45 days of customisation at EUR 1,200, another EUR 54,000. A custom ERP built exactly to her constraints is priced at EUR 240,000 plus EUR 35,000/year, so EUR 415,000 over five years. Vertical wins overall, but the gap shrinks to EUR 58,000 once customisations are factored in, and custom guarantees evolution without surcharges.
FAQ
What does a vertical ERP implementation cost in 2026 ? Between EUR 30,000 and 120,000 depending on scope and site count, on top of licences of EUR 50 to 150/user/month.
Why does custom take 8 to 14 months ? Because it models your real processes from scratch; count discovery, iterative development, testing and data migration, versus 4 to 6 months for a preconfigured vertical.
When should you pick a vertical ERP ? When 80 % of your needs match the sector standard and fast go-live outweighs differentiation.
Are vertical customisations expensive ? Yes: often EUR 800 to 1,500/day, and they must be retested at each version upgrade, creating a hidden recurring cost.
Does custom remove vendor lock-in ? Yes, you own the code and data; you fund maintenance (15 to 20 % of build/year) but no imposed licence.
