The verdict in three sentences
A complete business platform ships in 6 to 11 months in 2026, a functional MVP in 3 to 5 months. The number one delay factor is not the code but integration with your information system (+20 to 40 %) and the availability of business experts on the client side. A signed plan with payment milestones tied to concrete deliverables cuts timeline overruns in half.
The typical business platform timeline in 2026
Every project is unique, but the major phases are stable. Here are 2026 orders of magnitude for a medium-complexity business platform (10 to 20 screens, 2 to 3 user roles, 1 to 2 integrations).
| Phase | Duration | Deliverables | Payment milestone |
|---|---|---|---|
| Scoping & specs | 2-4 weeks | Prioritised backlog, wireframes, technical architecture | 15 % |
| UX/UI design | 3-5 weeks | High-fidelity mockups, design system | 15 % |
| MVP development | 8-14 weeks | Core features delivered in sprints | 40 % |
| QA & acceptance | 2-4 weeks | Testing, fixes, acceptance report | 20 % |
| Deployment & training | 1-2 weeks | Go-live, documentation, training | 10 % |
Cumulatively that is 16 to 29 weeks, i.e. 4 to 7 months for a controlled scope. A rich platform (multi-module, complex workflows) pushes the total toward 11 months.
What actually lengthens (or shortens) the timeline
Delays rarely come from developer typing speed. Here are the real levers.
| Factor | Impact on timeline | How to control it |
|---|---|---|
| Existing ERP/CRM integration | +20 to 40 % | Document APIs from scoping |
| Compliance (GDPR, regulated sector) | +2 to 6 weeks | Dedicated parallel workstream |
| Business stakeholder availability | +10 to 30 % | A named sponsor and product owner |
| Unfrozen scope (scope creep) | +30 to 100 % | Backlog frozen per sprint |
| Legacy data migration | +3 to 8 weeks | Data quality audit in phase 1 |
| MVP-then-iterate approach | -30 to 50 % | Deliver core value first |
The 2026 lesson: shipping an MVP in 3-5 months then iterating almost always beats the 11-month "big bang", because you capture real feedback and spread the investment.

Mini case study
Marc, IT director of an industrial SME in Grenoble, wants to replace three Excel spreadsheets with a production-tracking platform. Scope: 14 screens, 2 integrations (ERP + time clock). Without scoping, his vendor quoted "4 months". After scoping, the realistic plan comes out at 7 months (including +5 weeks for the ERP integration). Marc chooses a 4-month MVP covering production tracking without the time clock, goes live, then adds the time-clock integration in iteration 2. Result: value delivered 3 months earlier, budget spread out, and 2 overruns avoided thanks to payment milestones tied to acceptance.
FAQ
Can a business platform ship in under 3 months? Yes for a very tight MVP (5-8 screens, 1 role, zero integration), typically 8 to 10 weeks. Below that, it is a prototype, not production.
Why does scoping take 2 to 4 weeks? Because a poorly prioritised backlog costs 5 to 10 times more in development. Scoping is the most profitable investment in the project.
Are IT integrations really the main risk? Yes. A poorly documented ERP API or a late security access can add 3 to 6 weeks. We tackle them first in phase 1.
How do we secure timelines contractually? With payment milestones tied to deliverables (backlog, mockups, acceptance) rather than to dates. Each payment validates a measurable step.
Do we need to specify everything before starting? No. We freeze the foundation and the first 2 sprints, then refine. Over-specifying locks in choices that will change anyway.
