Choosing between Time & Materials and Fixed Price isn’t really about cost, it’s about risk, change, and how much clarity your project actually has at the start.
Most teams pick a contract model too early, without evaluating how often scope shifts, how predictable the work really is, and whether the supplier has delivered something similar before.
The result?
Projects get locked into a structure that doesn’t match reality.
A better approach is to choose the contract type based on expected volatility:
-If scope will evolve, you need flexibility.
-If scope is stable, you need predictability.
The model must fit the behaviour of the project, not the other way around.
At Found, we help teams align contracts with real-world delivery conditions so budgets, schedules and expectations stay grounded instead of optimistic.
Which contract type does your organisation default to and does it actually match how your projects run? 👇
