The numbers

What verbal change-order approvals cost: the numbers

The best-sourced numbers on what an unwritten change costs come from one study: the 2026 Dodge Construction Network and Clearstory survey, published on Clearstory's site in June 2026 from a survey of nearly 200 US general contractors and specialty trade contractors. On the specialty-contractor side it reports that the average time from a signed time-and-materials tag in the field to a fully priced change order request submitted to the general contractor is 22 days, and from that request to a signed change order back in the contractor's hands is another 26 days. It reports that 77 percent have had to write off change-order work as bad debt, for work that was done, billed and never recovered. And it reports that 97 percent sometimes begin work before a change order is approved, with 42 percent doing so more than half the time.

Three caveats travel with those numbers and this page keeps them attached. The figures are hosted by a vendor of change-order software, on its own site, and the report itself sits behind a lead form, so the question wording and the sample were not checked at the source for this page. The sample is about 200 firms. And the firms surveyed are construction subcontractors and the general contractors they bill, measured by the paper that moves between them: a time-and-materials tag, a change order request, a signed change order back. It is not a survey of home-service shops.

For residential service work, heating, cooling, plumbing and electrical repair on homes, there is no reliable number. Every figure found for those trades came from a vendor marketing page with no sample, no method and no year, and none of them is used here. This page does not invent one.

Coming to the Jobber App Marketplace.

What the numbers measure, and what they do not

The survey is self-reported: contractors describing how their own change-order process performs. Clearstory's report page states the sample as "Nearly 200 contractors nationwide" and dates the release June 2026 (report landing page; press release). The headline in the press release is that "only about one-third of both general and specialty trade contractors report that their current change order management process functions very well".

Two of its figures are one measurement stated two ways. The 22 days from tag to priced request and the 26 days from request to signed change order add up to 48 days, which is the press release's "full cycle from work performed to authorized change order averaging nearly 7 weeks". They are not two findings, and this page does not count them twice.

Clearstory also published a 2025 specialty-contractor report from a different survey, with a sample of more than 100 firms, in which more than half of respondents said it took 8 to 14 days to turn a signed tag into a priced request (2025 report). Different survey, different year, different sample: the two are not comparable and are not a trend line.

Residential: the honest gap

No trade-association figure on change-order write-offs, disputes or delay was found at a reachable URL for this page, and no residential service figure with a sample and a method behind it exists in any public source read. The closest thing with a real sample is on the homeowner side. According to the 2026 U.S. Houzz and Home Study, a survey of 10,176 renovating US homeowners about their 2025 projects, 31 percent expanded the scope of their project mid-renovation and 37 percent went over their set budget (Houzz). That is renovation, reported by homeowners, not a service call reported by a contractor. It says mid-job changes are common; it does not say what they cost a shop.

Where the money goes

Three places, in the survey's own terms, all from the 2026 Dodge Construction Network and Clearstory survey and all carrying the caveats above.

In a home-service shop the same three leaks have plainer names, and no number from this page attaches to them: the part that went on the truck's tally and never on the invoice; the invoice that came in above the quote and was argued down at the kitchen table; and the office hour spent rebuilding a change from a text thread. The mechanism is the same at any size. Work was done on a yes, and the yes did not carry a price.

The three habits that remove it

  1. One line, one price, and the new total. The change is written as one line with one number, and the customer sees what the whole job now comes to. Two changes are two lines. A yes with no price and no new total is a conversation, not an approval.
  2. Signature before the work. On the customer's own phone or on paper, before the extra work starts. Not a nod, and not a text that says ok with no price in it. The e-signature page has what the federal and California statutes say a signature on a phone is. In California the statute itself puts the signature before the work and names the three things the order must state; the California page quotes it.
  3. On the job and the invoice the same day. The approved line goes on the job record before the invoice is built, so the invoice matches what the customer signed and nobody rebuilds it from memory.

Each habit closes one of the three leaks above. The first removes the argument about the price. The second removes the work done on a yes. The third removes the office hour.

The free template and the app

On paper, the free change order template is one page with the fields the habits need: the change, the reason, the price of this change, the new job total, the effect on the schedule, how it is paid, and both signatures. PDF, Word, or a page you fill in on a phone, with no email gate.

For shops on Jobber, Volta Change Orders is the same record as a phone flow, coming to the Jobber App Marketplace: the tech says or types the change and its price, the customer sees the line, the price and the new total on their own phone, signs with a finger or a typed name, and taps Approve, and only then is one line written to the job in Jobber. Free until your first approved change order. The help center has the steps, in English and in Spanish.

Questions

How long does it take to get a change order approved?

In the 2026 Dodge Construction Network and Clearstory survey of nearly 200 US contractors, hosted on Clearstory's site, specialty contractors reported an average of 22 days from a signed time-and-materials tag to a priced change order request, and 26 more days from that request to a signed change order, about 48 days in all. That is construction subcontractors billing a general contractor. No comparable figure exists for residential service work.

How much money do contractors lose on verbal change orders?

No reliable figure in dollars exists at any source read for this page. The survey above reports shares, not amounts: 77 percent of specialty contractors have written off change-order work as bad debt, and 83 percent say the process hurts their cash flow. For home-service shops there is no reliable number at all, and this page does not invent one.

Do these numbers apply to HVAC or plumbing shops?

No. They were measured on construction subcontractors and general contractors, on the paper that moves between them. Nothing with a sample and a method behind it was found for residential heating, plumbing or electrical service. The mechanism is the same, work done on a yes that carried no price, and the three habits apply at any size; the percentages do not transfer.

Is it common to start the extra work before it is approved?

In that survey, 97 percent of specialty contractors said they sometimes begin work before a change order is approved, and 42 percent said they do so more than half the time. Same caveats: vendor-hosted, about 200 firms, construction subcontractors.

Where do the numbers come from, and can I read the study?

From a 2026 joint study by Dodge Construction Network and Clearstory, published on Clearstory's site as a press release and two report pages, which are linked under Sources. The full reports sit behind a lead form and were not downloaded for this page, so the sample size and question wording rest on the pages as published.

What does a written approval have to contain?

The change in one line, the price of this change, the new job total, and a signature before the work. In California a change order on a home improvement contract must also state its effect on the progress payments or the completion date, and must be in writing and signed before the work it covers begins; the California page quotes the statute. What counts as a signature on a phone is on the e-signature page.
