Not-to-exceed (NTE)
A not-to-exceed (NTE) amount is a contractual maximum. The agency will pay for actual work performed, up to that number and no further. NTE appears on task orders, on time-and-materials contracts, on professional services agreements and as the ceiling on an indefinite-quantity vehicle.
It is not a fixed price. Under a fixed price you are paid the full amount whether the work costs more or less. Under an NTE you are paid actual cost or actual hours, capped, so the upside of efficiency belongs to the agency and the downside of overrun belongs to you.
The short version
- NTE caps payment, not effort. If you exceed it without a written increase, the excess is usually your loss.
- Efficiency does not pay under an NTE. Coming in under the ceiling simply means you are paid less.
- Most contracts require you to notify the agency when spend reaches a percentage of the ceiling, often 75 or 80 percent.
- Raising an NTE is a change order and may need approval well above the project manager.
Why it matters to a bidder
NTE structures allocate risk asymmetrically, and the response is administrative rather than legal:
- Track burn weekly against the ceiling. The moment you cross the notification threshold, notify in writing. Agencies rarely fund an overrun disclosed after it happened.
- Get scope assumptions into the order. An NTE with a vague scope is an invitation to be asked for more work within a fixed cap.
- Price the estimate honestly. Deliberately low-balling an NTE to win a task order and then seeking an increase is a well-known pattern, and agencies that see it stop issuing you orders.
- Understand the funding reality. A public NTE usually reflects an appropriated or encumbered amount. If the money is not appropriated, no one can authorize you to exceed it.
A real example
An environmental consultant receives a $75,000 NTE task order for site characterization under an on-call agreement. Field conditions require additional borings. At $61,000 of spend the consultant notifies the county and requests a $28,000 increase. The county's threshold for administrative approval is $25,000, so the increase goes to the board of supervisors, which meets in three weeks. The consultant stops work at the ceiling and remobilizes after approval. Had it kept working, the extra would have been unfunded, and the county could not lawfully have paid it.
How state and local differs from federal
Federally, the analogous concepts are the contract ceiling and the Limitation of Cost or Limitation of Funds clauses, which require notice at defined percentages and expressly relieve the contractor of an obligation to continue beyond the funded amount. The rules are uniform and well litigated.
At the state and local level the constraint is appropriation law rather than a standard clause. Public agencies generally cannot pay beyond an encumbered or appropriated amount, and many state constitutions or charters bar obligations exceeding current appropriations. That produces two practical realities. First, an over-ceiling invoice is not merely disputed, it may be unlawful for the agency to pay. Second, multi-year contracts frequently contain a non-appropriation or funding-out clause allowing termination if the legislature or council does not fund the next year, which is a risk to price into any long-term NTE arrangement. Where the ceiling sits on a master vehicle rather than a single order, see IDIQ and job order contracting.
Common questions
Is NTE the same as a fixed price?
No. Fixed price pays the full amount regardless of cost. NTE pays actual cost or hours up to a cap.
What happens if I exceed the ceiling?
Generally you are not paid for the excess, and the agency may lack legal authority to pay it. Notify before you get close.
Can an NTE be raised?
Yes, by written modification, subject to the agency's approval thresholds, which may require a governing-board vote.
What is a non-appropriation clause?
A clause allowing the agency to terminate if funds are not appropriated in a future budget cycle. It is standard in multi-year state and local contracts.
