Fixed Price vs Time and Materials for Software Projects in Amsterdam in 2026

The verdict in three sentences

Two incomparable quotes for the same application almost always hide two different contract models: fixed price sells a firm price with a 15 to 30% risk margin, time and materials sells time at a day rate of 600 to 950 EUR in Amsterdam in 2026 (450 to 700 EUR in a French regional city such as Montpellier). For a project whose scope is not yet frozen, the best risk/price balance is the hybrid model: a fixed-price discovery phase of 4,000 to 10,000 EUR, then capped time-and-materials sprints. Whatever the model, three clauses protect your investment: code ownership, delay penalties and reversibility.

Why your quotes do not compare

A CFO at a Dutch SME typically receives three proposals: a systems integrator at 110,000 EUR fixed price, an agency at 80,000 EUR estimated in time and materials, a freelancer at 50,000 EUR. The first priced the worst case, the second the median case with no cap, the third the optimistic case. Without detailed specifications, none of the three prices means the same thing.

The 2026 numbers in Amsterdam

The Amsterdam market is one of the most expensive in continental Europe, close to Paris and above most French regional cities.

A two-week sprint with a senior developer, a half-time project manager and a quarter-time designer costs about 12,500 to 16,000 EUR. A mid-sized business application needs 6 to 10 sprints.

The clauses that really matter

Code ownership: require assignment of intellectual property rights on bespoke code upon payment of each invoice, and access to the Git repository from day one. Without this clause, copyright stays with the vendor.

Penalties: on fixed price, 0.5 to 1% of the amount per week of delay, capped at 10%, is a reasonable standard. In time and materials, penalties focus on team availability.

Reversibility: technical documentation, transfer of access (hosting, domains, store accounts) and 5 to 10 days of handover support for a new vendor. Budget 3 to 5% of the project for this lot.

Warranty: 3 to 6 months of free bug fixing after acceptance, whatever the model.

Mini case study

Sarah, CFO of a 60-employee distribution company in Amsterdam, needs an ordering portal for her resellers. She received a fixed-price offer of 100,000 EUR. She chooses instead a 8,000 EUR discovery phase that defines 42 priority user stories, then 6 sprints capped at 14,000 EUR, 84,000 EUR of sprints. After 5 sprints, the portal is live and the sixth sprint funds improvements requested by resellers. Total cost: 92,000 EUR, 8,000 EUR saved, with scope changes absorbed without change requests (on fixed price, two 6,500 EUR change requests would have pushed the bill to 113,000 EUR).

FAQ

Is fixed price always more expensive?

Not always: on a very stable and well-specified scope, the risk margin drops to 10 to 15% and fixed price is comfortable. It becomes costly when needs change during the project.

How do you keep time and materials under control?

Set a cap per sprint and an overall budget, require weekly tracking of days used and a demo every 2 weeks. A gap above 15% should trigger a decision.

What should a 4,000 to 10,000 EUR discovery phase include?

Business workshops, prioritised user stories, mock-ups of key screens, architecture and estimate per lot. The deliverable should let you consult another vendor if needed.

Who should own the code?

You, for all bespoke code, with a usage licence on the vendor's reusable components. Put it in writing in the contract.

Can we mix a local team with an offshore team?

Yes, with a local tech lead and developers at 200 to 380 EUR per day, sprint cost drops by 35 to 50%, provided governance is clear.
