Every unpaid change on a job started life as a change order request that never got made, got made too late, or got made so badly the owner could ignore it. That is the uncomfortable truth behind most “we did the work but they won’t pay for it” stories. The extra work was real. The cost was real. The request that should have locked the money in was a text message, a hallway conversation, or a number scribbled on the back of a plan sheet.
A change order request (some contracts call it a COR, a change order proposal, or a PCO) is the document you send before the extra work happens. It says what changed, what it will cost, how it affects the schedule, and asks for approval. Get that piece right and the change order that follows is a formality. Get it wrong and you are negotiating from the losing side of the table, after the drywall is already up.
This post walks through what a bad change order request actually costs, the five mistakes that cause the most damage, and two free ways to fix the process for good: a free Excel change order template if you live in spreadsheets, and a free digital change order tool if you would rather send it from your phone and get it signed on site.
What a sloppy change order request really costs
Contractors tend to think of the downside as “we might not get paid for that one item.” The real damage runs wider than that.
- Unpaid work. The obvious one. If the request is vague, late, or missing, the owner has every reason to argue the work was included in the original scope. On a $6,000 electrical change, losing that argument means you just funded the owner’s upgrade out of your margin.
- Schedule you cannot recover. A request with no time impact stated is read as “no time impact.” When the extra work pushes the finish date, you are now late on a job where you did more than you were paid for, and liquidated damages or an angry homeowner are on the table.
- Cash flow holes. Even when you eventually get paid, a disputed request sits outside the pay application for weeks or months. You have already paid the sub and bought the material. The owner has not paid you.
- Trust that does not come back. Owners remember the surprise invoice, not the extra work. A change order request that shows up after the fact reads as a shakedown even when it is completely fair.
- A weak position if it goes legal. Most construction contracts require changes to be requested and approved in writing. An undocumented request is the first thing the other side’s attorney will point at.
None of that is dramatic. It is just the slow, steady way small jobs lose money. Now the mistakes that cause it.
Mistake 1: Sending the change order request after the work is done
This is the big one. The crew hits an unexpected condition, the super makes a call to keep things moving, and the paperwork gets pushed to Friday. By Friday the work is complete and the request has turned into an invoice for something the owner never agreed to.
The real-world cost: you have thrown away all of your leverage. Before the work, the owner needs your approval to get what they want. After the work, you need their approval to get paid. Those are not the same negotiation. On a remodel where a homeowner asked for the shower to be moved “while you’re in there,” a $2,800 plumbing reroute done first and requested later is a $2,800 argument you will probably split down the middle just to close the job.
The fix: the request goes out the same day the change is identified, even if the pricing is preliminary. A one-line request that says “this is a change, rough estimate $2,500–$3,200, firm number tomorrow, work is on hold until you approve” beats a perfect request three days late every single time.
Mistake 2: Describing the change so vaguely it can mean anything
“Additional electrical work per owner request — $1,850.” That is not a change order request. That is an invitation to argue about what “additional” means six weeks from now.
The real-world cost: vague scope cuts both ways. The owner will read it as narrowly as possible when it comes time to pay and as broadly as possible when it comes time to ask for more. You end up doing the four extra outlets and the under-cabinet lighting and the dedicated microwave circuit for the price you quoted for the outlets alone.
The fix: write the scope so a stranger could build it. Reference the drawing or the room, list the quantities, and say what is excluded. A good change order request line looks like: “Add (4) 20A duplex receptacles on kitchen east wall per owner markup dated 9/2; includes rough-in, device, cover plate, and patch. Excludes paint.” Five extra seconds of typing, one fewer dispute.
Mistake 3: Pricing it from memory instead of a breakdown
A change order request with a single lump sum and no backup invites two bad outcomes. The owner either rejects the number because it “seems high,” or accepts it and later challenges it when a friend tells them they overpaid.
The real-world cost: pricing from memory almost always leaves money on the table. Contractors forget the dumpster pull, the second trip, the supervision hours, the overhead and profit they are entitled to under the contract, and the sales tax on material. Ten forgotten items at $80 each is $800 on a $4,000 change, and that is before you get talked down.
The fix: every change order request shows labor, material, equipment, sub cost, and markup as separate lines, with the revised contract total at the bottom. If you are working out of a spreadsheet, the free change order spreadsheet does the math for you: line items, markup, tax, and revised contract value calculate automatically, and it includes a log so every request on the job is tracked in one place. Spreadsheet people, that is your fix, and it costs nothing.

Most change order requests talk about money and say nothing about time. Then the extra work adds four working days, the substantial completion date slides, and the owner asks why you are late.
The real-world cost: on commercial work, silence on time impact can be treated as a waiver of your right to an extension. On residential work it turns into a soured relationship and, on occasion, a withheld final payment. Either way you did extra work and got punished for the time it took.
The fix: every request states the time impact in calendar days, even when it is zero. “Schedule impact: +3 working days to substantial completion” is one line. It protects you and it tells the owner the honest cost of what they are asking for, which is exactly what a professional is supposed to do. Our guide on change order time extensions covers how to word it.
Mistake 5: Requesting it verbally and calling that approval
“I talked to the owner, she said go ahead.” Everybody on the job has heard that sentence. Nobody on the job can produce it in writing when it matters.
The real-world cost: a verbal change order request is not a request, it is a memory, and memories differ. The owner remembers agreeing to “look at it.” The super remembers a yes. Without a signed document, the contract’s written-change clause controls, and that clause is not on your side. We wrote a whole post on why verbal change orders end badly.
The fix: the request is not done until it is sent in writing and approved in writing. That does not require a formal AIA G701 for a $600 change. It requires a document the owner can open, read, and sign. Which brings us to the second free fix.
The right way: two free fixes, pick the one that matches how you work
There is no trick here. A good change order request has six parts: a clear description, a priced breakdown, the time impact, a revised contract total, a place for the owner to sign, and a date. The only real question is whether you want to build it in a spreadsheet or send it from a phone.
Option A: the free Excel change order template
If your office runs on Excel and your PM wants a file on the server, the free Excel change order template is the fastest route. It is a professional, auto-calculating spreadsheet: enter your line items, set your markup and tax, and the revised contract value works itself out. It comes with a change order log tab so you can see every request on the job, its status, and the running contract total. Download it once, save a copy per project, and you are done. Best for people who want a document they control and print.
Option B: the free digital change order tool
If you are the one standing in the kitchen when the homeowner says “can we also...”, the free digital change order tool is built for that moment. Fill in the change on your phone, hit send, and the owner gets a clean, professional change order they can sign from their own phone in about 30 seconds. The signed copy is timestamped, the contract total updates automatically, and there is a record of exactly when it was sent and approved. Best for people who want the request out and signed before they leave the site. It is 100% free, no plan tiers, no catch.
Both do the same job. The spreadsheet gives you control; the tool gives you speed and a signature. Plenty of contractors use both: the tool on site, the spreadsheet log in the office.
A change order request checklist you can use tomorrow
- Identify the change the day it happens. Not Friday. Today.
- Stop the affected work (or note that you are proceeding at risk and why) until approval.
- Describe the scope so a stranger could build it. Reference drawings, rooms, quantities, exclusions.
- Break out the price: labor, material, equipment, subs, markup, tax. Show the revised contract total.
- State the time impact in days, even if zero.
- Send it in writing and get a signature before the work starts. A digital signature from a phone counts.
- Log it. Number it, track its status, and reconcile the log against your pay application.

Create a free change order →One last thing about the owner who “never signs anything”
Some owners drag their feet on every change order request as a negotiating tactic. The answer is not to skip the request. It is to make the request so easy to approve that dragging their feet looks unreasonable: clear scope, honest number, one tap to sign. When they still stall, you have a written record that you asked, priced it fairly, and waited. That record is worth more than the change itself if the job ever ends up in a dispute. We cover the hard cases in what to do when a client won’t sign a change order.
Frequently asked questions
What is a change order request?
A change order request (COR) is the written document a contractor sends to an owner or GC before performing extra or changed work. It describes the change, prices it, states the schedule impact, and asks for approval. Once approved and signed, it becomes a change order that formally amends the contract.
What should a change order request include?
A clear scope description with quantities and exclusions, a priced breakdown (labor, material, equipment, subs, markup, tax), the revised contract total, the schedule impact in days, a reference number, the date, and a signature line for the owner. Leaving any of these out is where disputes start.
Is there a free change order request template in Excel?
Yes. The free Excel change order template on this site is an auto-calculating spreadsheet with line items, markup, tax, revised contract value, and a change order log tab for tracking every request on the job. It is free to download and use on any project.
Can I send a change order request from my phone?
Yes. The free ChangeOrdersPro tool lets you fill in the change on site, send it, and have the owner sign from their phone in about 30 seconds. The contract total updates automatically and the signed, timestamped copy is kept on record.
