The verdict in three sentences
A usable MVP ships in 6 to 12 weeks, a full v1 in 4 to 8 months depending on business complexity. The main enemy of the schedule is not the technology but scope changes, which add an average of +20 to +40 % to the timeline. Securing a launch date means a frozen scope, two-week sprints and continuous QA rather than a final big-bang test.
The typical 2026 schedule
A structured application project always follows the same major phases. Here are the orders of magnitude seen on Berlin SME and scale-up projects in 2026.
| Phase | 2026 duration | Deliverable | Sign-off by |
|---|---|---|---|
| Discovery & workshops | 1 to 2 wk | Prioritised backlog, low-fi wireframes | Client product owner |
| UX/UI design | 2 to 3 wk | Hi-fi mockups, design system | Business + management |
| Dev sprints (MVP) | 6 to 10 wk | Core features tested | PO + QA |
| QA & fixes | 1 to 2 wk | Stabilised app, blockers cleared | Pilot users |
| Go-live | 3 to 5 days | Deployment, monitoring, training | COO / IT |
| Post-launch hardening | 2 to 4 wk | Adjustments, hypercare | Support team |
MVP does not mean "low-end": it means one value promise delivered cleanly. Anything not essential to launch moves to v1.1 or v2.
The measured impact of scope changes
Scope creep is the number one cause of delays. Each unplanned addition costs more than its dev time: it pushes back QA, re-triages the backlog and reopens closed topics.
| Type of change | Timeline impact | Budget impact | How to avoid it |
|---|---|---|---|
| New field / minor screen | +2 to +5 d | +1,500 to 4,000 EUR | v2 backlog |
| New user role | +1 to 2 wk | +6,000 to 12,000 EUR | Scope roles up front |
| Unplanned third-party integration | +2 to 4 wk | +8,000 to 20,000 EUR | List APIs during discovery |
| Rework of an approved flow | +2 to 3 wk | +7,000 to 15,000 EUR | Formally sign off mockups |
| Mid-project tech change | +4 to 8 wk | +20,000 EUR and up | Freeze the stack at discovery |
In agile, these changes are not forbidden: they enter the backlog and push other items out. Under fixed price they become change orders, which are slower to contract.
Mini case study
Julien, operations director at a logistics SME in Berlin, wants a route-tracking app for 40 drivers. MVP scope: mobile entry, dispatcher dashboard, exports. Quote: 58,000 EUR, quoted timeline 11 weeks.
In week 5 he asks to add customer signature and real-time geolocation. These two additions represent +3 weeks and +14,000 EUR. By moving them to v1.1 (launched 6 weeks after the MVP), Julien holds his original go-live date, trains his teams on the core, and spreads his cash flow. Result: on-time launch and gradual adoption instead of a full project delay.

FAQ
Can a web app be delivered in 4 weeks?
Only for a very small scope (one flow, no integrations). Below 6 weeks it is a prototype rather than a production MVP. A real business MVP needs 6 to 12 weeks in 2026.
Why does design take 2 to 3 weeks before dev?
Approved mockups prevent coding twice. Each flow redesigned mid-dev costs +2 to +3 weeks: investing up front halves the risk of drift.
Agile or fixed price to hold a date?
For a firm date with variable scope, capped-budget agile is safest: you ship what is ready by the date, prioritised by value. Fixed price freezes everything but makes each change slow.
How much QA time should I plan?
Budget 15 to 20 % of dev time for QA and stabilisation. On a 10-week MVP, plan 2 weeks of QA before go-live.
How do I truly secure the launch date?
Freeze the MVP scope, split into two-week sprints with demos, and refuse any non-critical addition until launch. Everything else goes to the v1.1 backlog.
