Fixed Price vs Time and Materials for MVP Development
Pricing model choice changes behavior. Fixed price can feel safer, while time-and-materials can feel flexible. The right model depends on scope certainty, risk tolerance, and decision speed.
1) When fixed price works
Fixed price works best when scope is narrow and stable. If major product questions are unresolved, the model often leads to strict change controls and relationship friction.
2) When time-and-materials works
Time-and-materials works well when you expect iterative discovery and changing priorities. It requires strong governance and clear milestone checkpoints.
3) Hybrid model for many startups
A common compromise is fixed scope discovery followed by milestone-based execution. This preserves flexibility while keeping budget visibility.
4) Contract terms that matter
Focus on acceptance criteria, change process, communication cadence, and exit rights. Contract clarity is usually more important than rate negotiation.
5) Decision framework
If scope is clear, fixed can work. If learning is still active, time-and-materials with strict reporting is safer. Choose based on uncertainty, not preference alone.
