A lump sum contract is a legal agreement where a contractor agrees to complete an entire project for a fixed, pre-agreed price. The key aspects are that the focus is on completing the whole project, not individual tasks, and the client knows the total cost upfront. The main advantages are minimal risk and costs for the client, and predictable cash flows and overhead costs. The main disadvantages are it is not suitable for complicated or changing projects, and the contractor faces high risk if costs are underestimated. It differs from a cost plus contract, where the client pays all costs plus fees, and from a unit price contract, which covers multiple lump sum contracts for a multi-stage project.
