Contractor Change-Order Benchmarks
Scope always changes. The only question is whether you price it before you build it. The approval, capture, and unpriced-scope ranges below are Level field observations, practitioner ranges from our work with contractors rather than a measured survey distribution. The field-rework cost figure is cited from a peer-reviewed ASCE study.
Key Finding
Best-in-class contractors approve 95%+ of change orders before doing the work. Laggards approve under 60%.
This is a Level field observation from client work, not a survey distribution. Disciplined contractors treat every scope change as a priced, signed change order before the crew touches it. Undisciplined contractors do the extra work first, then try to bill for it later, or never bill for it at all. Unpriced scope creep is invisible on the P&L. There is no line item for work you did but never charged for. It shows up only as a job that came in under the margin you bid.
That gap is pure margin, because the labor and materials were already spent. Systematizing change-order capture is one of the highest-return operating fixes a contractor can make.
Change-Order Field Observations
The ranges below are Level field observations, drawn from our work with contractors rather than a measured benchmark distribution. No public dataset publishes change-order approval or capture rates, and these figures are not part of the Level Index dataset. The one externally sourced row, field-rework cost, is cited from the ASCE Journal of Construction Engineering & Management (2026).

What the data tells us
Approve before you build, or you will not get paid
In Level's field experience, top contractors approve 95%-plus of change orders, and the discipline is the timing: price it, sign it, then do it. Once the crew has already completed the work, the customer has little reason to pay for a change they have already received. The gap between a 95% shop and a sub-60% shop is almost entirely process, not customer type.
The more custom the work, the wider the gap
Standardized service and replacement work picks up a change order on relatively few jobs. Custom and commercial work sees far more. More scope changes means more opportunity, and more risk. The disciplined shops turn that volume into billed revenue; the undisciplined ones turn it into unbilled labor. This is a pattern we observe in the field, not a surveyed rate.
Rework and uncaptured scope are pure margin
Field rework runs about 0.38% of contract value precompletion, rising to ~0.76% once postcompletion corrections are included, in peer-reviewed ASCE work, with older Construction Industry Institute estimates above 5%. On top of documented rework, every uncaptured change-order dollar is margin, not revenue, because the cost was already incurred. Recovering that share does not require winning new work, it requires a signature and a process that fires before the crew does the extra scope.
Unpriced scope is the reason good jobs come in under margin
When a job you bid well finishes below target margin, the usual suspects are labor overruns or a bad estimate. Often the real cause is scope that grew after the contract and never got a change order. This is why change-order discipline lives inside job costing: without it, you cannot tell a labor problem from an unbilled-scope problem.
The CLEAR Framework for Contractors
Learn moreEvery contractor runs on five financial pillars. Change-order capture sits at the center of the E pillar, where scope turns into billed margin.
DSO, invoice speed, retainage, progress billing. The gap between completing work and collecting payment is where most contractors bleed cash.
Hours vs budget, technician utilization, billable capture, callbacks. Unpriced scope shows up here first, as labor spent on work no one billed.
Job-level margins, change-order capture, service agreement profitability. Unpriced scope creep is the most common reason a well-bid job finishes under margin.
Quote conversion rate, pull-through revenue, customer retention. The best contractors generate 2-4x more repair revenue from SA customers than non-SA (Level pull-through analysis).
Customer concentration, warranty exposure, bonding capacity. A single customer above 20% of revenue is one lost contract away from a cash crisis.
Frequently Asked Questions
What share of change orders should a contractor get approved?
In Level's field work with contractors, best-in-class shops approve 95% or more of the change orders they identify, and they price and approve them before the extra work is done. The laggards approve under 60%, which means more than four in ten scope changes get built without a signed, priced change order. That unbilled work is done at zero revenue and full cost, so it lands straight against margin. These are practitioner ranges from client work, not a measured benchmark distribution.
Why does unpriced scope creep never show up on the P&L?
Because there is no line item for work you did but never billed. A change order that never gets priced does not appear as a loss, it appears as nothing. The only signature it leaves is a job that came in under the margin you bid. Owners then blame labor overruns or bad estimating, when the real cause is scope that grew after the contract was signed and never got captured. It is the most invisible margin lever in contracting precisely because it hides inside otherwise normal-looking jobs.
How much does rework and unpriced scope actually cost?
A peer-reviewed study in the ASCE Journal of Construction Engineering & Management puts precompletion field rework at about 0.38% of contract value on average, rising to about 0.76% once postcompletion corrections are included. Older estimates from the Construction Industry Institute run higher, above 5%, so treat the ASCE figures as a rigorous low-end anchor. On top of documented rework, unpriced change-order scope adds cost that never gets a line item at all, which is why the total drag on a job can be far larger than the rework number alone.
How quickly should a change order be approved?
The discipline that matters is approving before the work is done, not the raw number of days. In Level's experience, top performers turn a change order around in a couple of days because they have a standard process: identify the scope change, price it, get a signature, then build. The laggards take a week or more, by which point the crew has usually already done the work, which makes the customer far less willing to pay for something they have already received.
From clients
What contractors say after working with us.
“Thought we were running 22% net. Real number was 11 once Sam allocated overhead correctly across labor and materials. Painful conversation but I needed it. We've been repricing every job since.”
“We had 40 service contracts and no idea which ones actually made money once you included drive time and callbacks. Sam ran the analysis, three of our biggest were underwater. Repriced or dropped them, net margin went from 8% to 14% in one quarter.”
“My CPA is great at taxes but nobody was looking at the actual business. Sam found $140K in overhead we were eating on service calls because our flat rates were 3 years out of date. Repriced the menu in 30 days. The pricing fix alone covers his fee for years.”
