Fixed Price vs Time and Material: Which Software Contract Is Right for You?
Fixed price vs time and material vs dedicated team: budget certainty, flexibility and risk compared, plus a practical hybrid approach.

Quick answer
Choose a fixed-price contract when the scope is small, clear and unlikely to change, for example a defined MVP feature set or a website. Choose time and material (T&M) when requirements will evolve, as they do in most product development, so you pay for actual work and can reprioritise each sprint. A dedicated team model suits long-term products that need continuous development.
The Three Common Engagement Models#
- Fixed price. Agreed scope, timeline and price up front.
- Time and material. You pay for hours or days worked; scope can change sprint by sprint.
- Dedicated team. A team works on your product full-time for a monthly fee.
Fixed Price vs Time and Material#
- Budget certainty. Fixed: high. T&M: managed through sprint planning and caps.
- Flexibility. Fixed: low, changes need change requests. T&M: high.
- Upfront effort. Fixed: detailed specification needed first. T&M: start sooner with a backlog.
- Risk. Fixed: vendor prices in risk; scope disputes possible. T&M: client carries more budget risk but gets transparency.
- Best for. Fixed: small, well-defined projects. T&M: evolving products and MVPs.
The Practical Middle Ground#
Many teams start with a fixed-price discovery or proof of concept, then move to time and material with a monthly budget cap and fortnightly demos. You keep control of spend while still adapting to what users teach you.
Tips for Either Model#
- Agree on what 'done' means for each feature.
- Insist on regular demos of working software.
- Keep a prioritised backlog you can see and change.
- Make sure you own the code and accounts from day one.
