There's a particular frustration that every specialty trade contractor knows but rarely sees quantified. You scope the work. You mobilize the crew. You do the work (often before change order paperwork has caught up) and then you wait. You submit the Change Order Request (COR) and you wait some more. Weeks go by. The GC has questions. There are revision requests. More waiting. And every day that passes is another day cash flow is under pressure.
New research from Clearstory and Dodge Construction Network, Optimizing the Change Order Process for Specialty Trade Contractors, puts hard numbers on what that process actually costs. Commissioned by Clearstory and based on a survey of US GCs and specialty contractors, the findings are a detailed accounting of where trades are losing time, losing money, and in some cases losing GC relationships they spent years building.
The story the data tells has two parts, and both have real implications for future business, team morale, and the bottom line.
Part One: The Internal Gap
Before a COR ever lands in a GC's inbox, there's a process that happens inside the specialty contractor's own operation. Field crews do the work. Someone captures it on a T&M tag (usually on paper), and then that tag travels from the field to the office. Someone prices it, organizes and assembles the backup documentation, and submits it to the GC.
According to the Dodge research, the average time from a signed T&M tag in the field to a fully priced COR submitted to the GC is 22 days. Over a third of trade contractors say it takes three weeks or more. That's three weeks where the billing clock hasn't started yet. Three weeks where you've already funded the labor and materials, and the payment cycle is still sitting at zero.
The reasons aren't hard to understand. Two-thirds of specialty contractors still use paper T&M tags. Pricing happens manually, often in spreadsheets. The COR gets assembled from separate documents, attached to an email, and sent off with no way to know if the GC actually opened it. Nearly all of these internal steps create delay, and the delays compound.
The result is that by the time a specialty contractor submits a COR to a GC, significant time has already passed, and the work communicated in that COR is now weeks old.
Part Two: The External Gap
Once the COR reaches the GC, a second clock starts. And it doesn't move fast.
The research found that the average time from COR submission to a signed change order back in the specialty contractor's hands is 26 days. 43% of trade contractors say it takes three weeks or more to get that authorization. Pricing disputes, scope disagreements, revision requests, and approval delays all add friction. More than half of all CORs require two or more revision cycles before reaching approval, each cycle adding time and extending the gap between work performed and payment received.
Put those two numbers together and the picture comes into focus. In a typical scenario, a specialty contractor does T&M work on a Monday, gets it fully priced and submitted to the GC roughly three weeks later, and receives authorization three to four weeks after that. From the day the work happened to the day the change order is officially approved, nearly two months may have passed. And that's before payment terms kick in.
For specialty contractors operating on tight working capital, that timeline is a cash flow problem that compounds across every active project.
The Documentation Problem Underneath It All
What makes the approval gap worse is that a significant share of the delay is process-driven and preventable. The most common reason GCs withhold or reduce change order payments is disputed pricing, cited by 66% of GCs. Insufficient backup documentation is second, at 53%. Disputed root cause, lack of agreement that the work was in scope, and disputed quantities follow.
These are documentation problems. They're also largely avoidable with better processes.
The research found that 97% of specialty trade contractors sometimes begin work before a change order is officially approved. In fact, 42% do it more than half the time. But it means that when the COR eventually gets submitted, it's describing work that already happened, often documented after the fact, on paper, without the kind of real-time backup that makes approval straightforward.
The cycle that results is predictable: late submission, insufficient documentation, GC questions, revision request, delay, negotiated-down settlement. More than half of GCs say they don't pay the full requested amount on more than 20% of the change orders they manage. For trade contractors starting work before approval and then submitting CORs weeks later, that math shows up directly in their margins.
What It Costs Beyond the Invoice
The financial impact is measurable. 83% of specialty contractors say the change order process has a negative impact on their cash flow, including 77% who have had to write off change order work as bad debt for work that was done, billed, and ultimately unrecoverable.
But the research also documents a set of costs that don't show up on a P&L.
94% of specialty contractors report that change order issues have strained their relationships with GCs. 48% have had disputes escalate to arbitration or a legal process. And 27% (more than one in four) have made the decision to stop working with a specific GC entirely because of change order issues.
That last number is worth sitting with. GC relationships are how specialty contractors grow. Repeat work, referrals, and preferred sub lists are business growth levers built over time and lost faster than they're earned. When a change order dispute poisons a relationship badly enough that a trade contractor walks away from a GC customer, the cost of that decision extends well beyond the disputed invoice.
The human toll is consistent with that. 98% of trade contractors report that the change order process is increasing stress levels for their staff, and 96% say it's decreasing job satisfaction. It’s a workflow problem significant enough to affect culture and retention.
What the Top-Performing Firms Are Doing Differently
The research also segments specialty contractors by how systematically they manage their change order process, and the performance differences between the top tier and everyone else are significant.
Top-performing trade contractors are far more likely to track change order KPIs consistently: things like outstanding exposure as a percentage of contract value, average days from submission to approval, and the percentage of change order value written off. The gap is striking: 55% of top-tier trade contractors track these metrics versus just 26% of their peers.They're more likely to use digital T&M tags rather than paper. They're more likely to have standardized COR templates and shared logs that their GC can access in real time.
The practical effect of those practices is faster internal processing, better documentation, fewer revision cycles, and stronger relationships with GC partners. The internal 22-day gap shrinks. The external 26-day gap shrinks. The write-offs disappear.
The research found that 54% of trade contractors agree that better visibility into their change order revenue exposure would help them proactively address financial risk before it becomes a problem. The tools and practices exist. The gap is in whether firms are using them consistently.
The Bigger Picture
The Dodge research covers a wide range of change order process findings, including the causes of disputes, the role of standardization, the appetite for digital adoption, and what both GCs and trades believe would improve the process most. 78% of contractors say a standardized, efficient, and transparent digital change order process would have a meaningful, positive impact on their business. One in three says the impact would be high or transformative.
For specialty contractors, the case for improving the process is more urgent than it might be for GCs. Trades fund the work first and wait to get paid. Every inefficiency in the process, whether internal or external,- is time that capital is tied up in completed work that hasn't yet been billed, approved, or paid.
Every specialty contractor knows the change order process is frustrating. What most don't know is exactly where their operation stands relative to the firms that have figured it out. The full report gives you that benchmark: where the top performers are, what they're doing differently, and how big the gap is between current state and what's possible.
