The verdict in three sentences
Redesigning a B2B site in phases lets you go live with an MVP from €6,000 to €12,000 (5 to 7 weeks) then add features through iterations. The smoothed total reaches €15,000 to €30,000 over 6 to 12 months, without tying up all your cash at once. The advantage is not only financial: each phase generates measurable results that fund the next one.
The three-phase roadmap
The principle: deliver first the foundation that pays (the MVP), then enrich it according to business priorities and available cash flow.
| Phase | Content | Budget (EUR) | Timeline |
|---|---|---|---|
| Phase 1 — MVP | Design, key pages, forms, mobile | 6,000 – 12,000 | 5 – 7 wks |
| Phase 2 — Content | Blog, multilingual, CRM integrations | 5,000 – 10,000 | +4 – 6 wks |
| Phase 3 — Optimisation | Personalisation, AI, advanced performance | 4,000 – 8,000 | +4 – 6 wks |
| Smoothed total | 15,000 – 30,000 | 6 – 12 months |
Go-live happens from phase 1: the site lives and converts while the following phases are prepared.
The cash-flow impact
For a finance director, the difference between a single payment and staged spending changes the cost profile and the risk.
| Approach | Cash outflow | Time-to-market | Risk | Adjustability |
|---|---|---|---|---|
| Big bang (all at once) | €15,000 – 30,000 immediate | 12 – 18 wks | High | Low |
| Phased | €6,000 – 12,000 upfront | 5 – 7 wks | Controlled | High (each phase) |
Spreading it allows trade-offs: if phase 1 underperforms, you adjust phases 2 and 3 rather than having spent everything.

Mini case study
Sarah, finance director of a B2B SME in Lille (industrial distribution), wants to redesign her site but refuses to tie up €24,000 in one quarter. Chosen split: phase 1 MVP €10,000 (live at 6 weeks), phase 2 €8,000 at month 4, phase 3 €6,000 at month 8. Total: €24,000 spread over 8 months, i.e. €3,000/month on average instead of a single outlay. From phase 1, the new site generates +30% quote requests, which partly funds the following phases and makes the investment nearly cash-neutral.
FAQ
Is the site really usable from phase 1? Yes: phase 1 delivers a complete, professional site (design, key pages, forms, mobile). Later phases add features, not fixes.
Does spreading cost more overall? Very little: the smoothed total (€15,000 to €30,000) is comparable to a single project, with a slight coordination overhead offset by faster go-live and the ability to adjust.
Over how long can you spread it? Generally 6 to 12 months in 2026. Beyond that, the risk of desynchronisation between phases rises and it is better to tighten the roadmap.
Can priorities change between two phases? Yes, that is the whole point: after phase 1 you reassess and re-order phases 2 and 3 based on real results and business needs.
Which phase delivers the best ROI? Almost always phase 1 (MVP): it restores the site's ability to convert. Later phases optimise an already profitable base.
