Fixed-Price Project
Best suited toDefined-scope builds where budget certainty and contractual milestones are non-negotiable
Appropriate for organisations that have completed discovery and can commit to a documented scope before development begins. Requirements, acceptance criteria, milestones, and total cost are contractually fixed, giving procurement, finance, and legal teams a predictable commercial baseline. Change requests are handled through a formal variation process, preserving budget integrity and preventing scope drift from eroding delivery timelines. Well matched to net-new platform builds, legacy modernisation, versioned product releases, and bounded migrations where stakeholder sign-off is required at defined stages. Less appropriate for exploratory or iterative work where requirements are expected to evolve materially during delivery, or where discovery and build are intended to run concurrently. Deliverables, acceptance criteria, and payment schedules are documented in the contract before a single line of code is written.
