Time and Materials (T&M)
Also known as: T&M
Time and materials (T&M) is a contract structure where the supplier is paid for the actual labour hours worked and materials used, at agreed rates.
Under a T&M contract the buyer pays an agreed hourly or daily rate for labour plus the cost of materials, often with a markup. It is well suited to work where the full extent cannot be predicted, such as maintenance, repairs or evolving projects, because payment tracks the effort actually expended.
The flexibility of T&M comes with the need for tight oversight: timesheets, material records and often a not-to-exceed ceiling keep spending controlled. It contrasts with a fixed-price contract, where the supplier commits to a set figure, and buyers frequently move from T&M to fixed price once the scope becomes clear enough to specify.
Frequently asked questions
- What is a time and materials contract?
- A time and materials (T&M) contract pays the supplier for actual labour hours and materials used at agreed rates, suiting work whose full scope cannot be predicted in advance.
- How is time and materials different from fixed price?
- T&M pays for the effort and materials actually used, so the final cost varies, while a fixed-price contract sets a single agreed figure regardless of the supplier's actual costs.
