Is fixed-price cheaper than time-and-materials?

Not necessarily. Fixed-price quotes include a risk premium (typically 15–30%) to cover underestimation. If the project goes smoothly, T&M would have been cheaper. If it goes over estimate, fixed-price saves you money.

What happens if scope changes in a fixed-price project?

Scope changes require a change order with updated pricing. This is where fixed-price contracts get messy — which is why milestone-based pricing is often the better approach.

Fixed-Price Development Explained

Budget certainty for software projects — when it works, when it does not, and a better alternative.

Fixed-Price Development

A pricing model where the total cost of a project is agreed upon upfront based on a defined scope, and the development team delivers within that budget regardless of actual hours spent.

Explanation

Fixed-price contracts give clients budget certainty but require well-defined requirements upfront. The risk shifts to the development team: if they underestimate, they absorb the cost. This creates tension — developers may cut corners to stay within budget, or scope disagreements arise when requirements evolve. Fixed-price works best for small, well-defined projects. For larger projects, milestone-based pricing (fixed price per milestone with scope flexibility between milestones) offers a better balance.

Bookuvai Implementation

Bookuvai uses milestone-based fixed pricing — each milestone has a fixed price, but future milestones can be re-scoped based on learnings. This gives clients budget predictability per phase while maintaining the flexibility to adapt as the project evolves. Full project fixed-price quotes are available for well-defined projects under 500 hours.
