The verdict in three sentences
An industrial SaaS is not built in one block: it advances through phases with go/no-go milestones so you never commit the next budget without proof. In 2026, budget EUR 5,000-12,000 for scoping, an MVP at EUR 50,000-110,000 over 12-16 weeks, then a scale phase at EUR 40,000-90,000. The industry-specific challenge: integrating sensors and ERP without blowing up scope.
3-phase roadmap with deliverables and budgets
In London, industrial SMEs often digitize a production-tracking or maintenance process. Phasing lets you validate internally before investing in the commercial version.
| Phase | Objective | Duration | Budget | Key deliverable |
|---|---|---|---|---|
| 0. Scoping | Specs, feasibility, ROI | 2-3 wks | EUR 5,000-12,000 | Spec sheet + estimate |
| 1. Internal MVP | Core process digitized | 12-16 wks | EUR 50,000-110,000 | Internally usable SaaS |
| 2. Scale & commercialize | Multi-tenant, integrations | 10-14 wks | EUR 40,000-90,000 | Sellable product |
Post-launch maintenance runs EUR 1,000-2,200/month depending on integration load and target SLA. Each phase ends with a decision milestone.
Industrial MVP breakdown (phase 1)
The industrial specificity lies in two packages: sensor/IoT integration and ERP integration (SAP, Sage, Oracle). These are what swing the budget by a factor of two.
| Work package | Effort (days) | Budget |
|---|---|---|
| Detailed scoping + design | 12-16 | EUR 7,000-10,000 |
| Foundation (auth, accounts, roles) | 8-12 | EUR 4,500-7,000 |
| Core business process | 35-50 | EUR 20,000-30,000 |
| Sensor/IoT integration | 12-25 | EUR 7,000-15,000 |
| ERP integration | 12-22 | EUR 7,000-13,000 |
| Dashboard + reporting | 10-16 | EUR 6,000-9,500 |
| DevOps + QA | 10-16 | EUR 6,000-9,500 |
| MVP total | 99-157 | EUR 57,500-94,000 |
With contingency you land within the EUR 50,000-110,000 range. If sensor integration is not needed for the MVP, remove EUR 7,000-15,000 and 2-3 weeks.
Go/no-go decision milestones
| Milestone | Question | Go criterion |
|---|---|---|
| End of phase 0 | Does ROI justify the build? | Estimated gain > 2x budget/year |
| Mid-MVP (W8) | Does the core work? | Internal demo validated |
| End of phase 1 | Real internal adoption? | > 70% of teams using it |
| End of phase 2 | External market interest? | 3+ qualified prospects |

Daniel, industrial director of a 90-person SME in London, wants to digitize maintenance tracking for his production lines, today on Excel. Phase 0 at EUR 9,000: scoping estimates a saving of 1,200 hours/year of data entry and search, i.e. ~EUR 48,000/year in value. The internal MVP is quoted EUR 78,000 over 14 weeks, sensors included. With an annual gain of EUR 48,000, the MVP pays back in ~20 months. After 6 months of internal use (85% adoption), he triggers phase 2 to commercialize the tool to 4 other manufacturers in his cluster: the internal SaaS becomes a revenue center.
FAQ
Why pay for scoping before developing?
Because EUR 5,000-12,000 of scoping avoids EUR 50,000 of misdirected build. Scoping freezes the specs, quantifies ROI and enables a first rational go/no-go before any heavy commitment.
What funding for an industrial SaaS in 2026?
Innovation loans, R&D tax credits and regional grants can cover part of the build. Amounts depend on profile and are never guaranteed; investigate from phase 0.
Is ERP integration always needed for the MVP?
No. If the core process works standalone, ERP can wait for phase 2. Deferring that integration cuts the MVP by EUR 7,000-13,000 and speeds validation.
What happens if a milestone is "no-go"?
You stop or pivot without having committed the next phase. That is the whole point of phasing: the maximum budget exposed at any point in time is that of a single phase.
Can an internally built tool really be commercialized?
Yes, provided it was planned from scoping (multi-tenant architecture). Phase 2 turns the internal process into a sellable product, often for companies in the same sector.
