labor and materials (time and materials)
n. what some builders or repair people contract to provide and be paid for, rather than a fixed price or a percentage of the costs. In many states, if the person performing the work is not a licensed contractor, he/she is limited to labor and materials in any lawsuit for contract payment, and may not receive a profit above that amount. Consumers who believe they will get a better deal from someone working for labor or time and materials should beware and watch receipts and keep track of actual labor hours worked.
