The worst conversation on any job is the one that starts with "I never approved that." You know you built it. Your crew remembers building it. But it is month four, the guy who verbally okayed it has moved on, and the only record you have is a text thread you cannot scroll back far enough to find. That is why learning how to track change orders matters more than almost any other piece of paperwork on your job — because untracked work is unpaid work, and it is your money, not theirs.
Nobody sets out to lose track. It happens the way it always happens: three changes in one week, a busy Friday, a promise to "write it up Monday," and then Monday brings its own fire. Six weeks later you are staring at a budget that does not match the job you actually built, and you cannot prove why.
What untracked change orders actually cost you
Contractors tend to think of a lost change order as one missed invoice. It is rarely that clean. Here is what it really drags along with it.
- The work itself. You paid labor, you paid for material, you ate the equipment time. That money is already out the door whether or not you ever bill for it.
- The schedule you never got credit for. Extra work takes extra days. If those days are not documented against a change order, they get counted as your delay. Now you are defending yourself over a hold-up you did not cause.
- Your contract value drifts out of sync. If you do not track the revised contract total after every approved change, your billings, your percent complete, and your remaining balance are all wrong. Progress billing off a stale number is how you end up over-billed on paper and under-paid in the bank.
- Retention and closeout drag on. Disputed extras are the classic reason a final payment sits for months. Every unresolved change order is a reason for someone to hold your check.
- You lose your negotiating position. With clean records you are negotiating. Without them you are asking a favor. Homeowners and GCs both know the difference.
- The relationship sours. Presenting a homeowner with a surprise five-figure total at the end — work they genuinely do not remember agreeing to — is how a good client turns into a bad review.
None of that requires a bad client. It only requires a bad system, and "I will remember" is a bad system.
How to track change orders: the seven fields you actually need
A change order log does not need to be complicated. It needs to be complete and it needs to exist. Whatever tool you use, every change on the job should carry these seven pieces of information:
- Number. Sequential, per job. CO-001, CO-002, CO-003. Never reuse a number, never skip one. Gaps are the first thing a suspicious client will ask about.
- Date requested and date approved. Two separate dates. The gap between them tells you who is slow, and it is your evidence if the delay was not yours.
- Who asked for it. Homeowner, architect, GC, inspector, or you. This one field settles most arguments before they start.
- Plain-language scope. Two or three sentences a normal person can understand. "Relocate kitchen island 18 inches north, includes re-routing waste and supply and patching slab." Not "per plan revision B."
- Dollar amount. Labor, material, subs, markup, tax — and one clear total. If it is T&M, say so and cap it.
- Schedule impact. In days. Zero is a legitimate answer, but write the zero. Blank looks like you forgot.
- Status and signature. Pending, approved, rejected, or void — and where the signed copy lives. An approved change order with no signature attached is a story, not a record.
Add one running total at the bottom: original contract value, plus approved changes, equals current contract value. That single line is the most useful number on the whole log, and it is the one almost nobody keeps current.
Four tracking habits that quietly break down
1. Tracking in your head until "the paperwork day"
There is no paperwork day. There is always another job. Every hour between the verbal go-ahead and the written record is an hour where the details blur and the client's memory of the price starts drifting downward. Cost: the difference between what you quoted and what they now remember hearing.
2. One spreadsheet per job, saved on one laptop
It works right up until the laptop is at the office, the change is on site, and the guy on site is not you. What gets written down is whatever survives the drive home. Cost: the changes that never make it into the log at all — usually the small ones, which add up faster than anyone expects.
3. Text messages as the system of record
A text saying "yeah go ahead" is better than nothing, and it is still weak. It rarely contains a price, it almost never contains a schedule impact, and it lives in a thread with four hundred other messages. Cost: hours of scrolling, and an approval that covers the work but not the amount. See our breakdown of why verbal change orders cost you money for how fast this one unravels.
4. Tracking the change but never updating the contract total
This is the sneaky one. You write every change order properly, you get them all signed, and you still never roll them into the contract value. Then you bill 80% of a number that is $40,000 out of date. Cost: cash flow you are entitled to, sitting on the table for months. It is the same underlying problem we covered in why your change order process is costing you money.
Two free ways to track change orders — pick the one you will actually use
The best tracking system is the one that fits how you already work. There are two honest options, and both of ours are free.
If you think in spreadsheets: use a proper log file. Our free Excel change order template includes both a formatted change order sheet and a tracking log tab, so every change you write is captured on one page with its number, date, status and dollar amount, and the revised contract value calculates itself as you go. It works offline, it lives in your own folders, and you can email or print a clean PDF of any single change order straight from it. If your bookkeeper already lives in Excel, this is the path of least resistance — you can download the free change order spreadsheet and have a log running on your current job in about ten minutes.
Grab the free Excel change order template
A professional, auto-calculating change order spreadsheet — line items, markup, tax and your revised contract value all worked out for you, plus a log to track every change order on the job. Free to download and use on any project.
Download the free Excel template →If you want it handled from the truck: use the free digital tool. ChangeOrdersPro lets you write the change order on your phone while you are still standing in the room where the change happened, send it, and have the client sign it with their finger. Every change order on the job sits in one list with its status, so "how many are still pending?" takes three seconds to answer instead of an afternoon. Approved changes roll into the project contract value automatically, so the running total is never stale. Like the template, the digital version is completely free to use — if you are wondering where the catch is, we explain the whole thing on our pricing page.
Plenty of contractors run both: the spreadsheet for the office copy and the accountant, the app for capturing changes in the field. Whichever way you go, the rule is the same — one system, one place, every change in it, no exceptions for small ones.
The ten-minute Friday routine
Tracking fails because it is treated as a project instead of a habit. Block ten minutes at the end of every week and run this list on each active job:
- Walk the job in your head, day by day. Anything built that was not on the original scope? Write it up now, even if the price is still an estimate.
- Open the log. Every pending change order older than seven days gets a follow-up message today. Not next week.
- Check that every approved change has a signature attached. Chase the ones that do not.
- Update the running contract value and compare it to what you have billed to date.
- Flag anything a client has told you to "just do" without approving. Those are the ones that turn into fights.
Ten minutes. Five steps. It is the cheapest insurance in this business, and the contractors who do it are the ones who are not chasing money in November for work they finished in June.
A quick example of what good tracking looks like
Kitchen remodel, original contract $86,400. Over eleven weeks the job picks up six changes: relocating the island ($3,180), upgraded appliance circuit ($740), rot repair found behind the sink wall ($1,950 T&M, capped at $2,400), a homeowner-requested tile change ($2,610), a credit back for a cabinet the client sourced themselves (−$1,200), and an extra day of demo caused by the rot ($0, three days added to the schedule).
Tracked properly, that is a two-minute conversation at closeout: contract value is now $93,680, here are six signed change orders, here are the three added days and here is who caused them. Tracked badly, it is a $7,280 argument with a client who remembers agreeing to "a couple of small things," plus a delay claim you cannot defend. Same job. Same work. The only difference is the log — and the same logic applies whether you are running a remodel or a formal approval process on a commercial job.
If you want more background before you set yours up, the rest of our change order guides cover pricing, markup, and getting signatures fast.
Skip the Word doc. Send it in 30 seconds.
ChangeOrdersPro turns this into a 30-second job — fill in the change, hit send, and your client signs from their phone. The contract total updates itself. It’s 100% free.

How do I track change orders on a small residential job?
The same way you would on a big one, just lighter. Number every change sequentially, record the date, the requester, a plain-language scope, the dollar amount, the schedule impact and the signature. A single log file per job is enough. The free Excel change order template already has the log tab built, so you are not designing a system from scratch.
Is an Excel change order log good enough, or do I need software?
A spreadsheet log is genuinely good enough if you keep it current and it is accessible when changes actually happen. The usual failure is not the format, it is that the file lives on one laptop and the change happens on site. If that describes your week, a phone-based tool will capture more changes than a spreadsheet will. Both of ours are free, so it costs nothing to try one and switch if it does not fit.
Where can I get a free change order log template?
Download the free Excel change order template from our site. It includes a formatted change order sheet plus a tracking log that totals your approved changes and updates the revised contract value automatically. No cost, no trial period, and you can edit it however you like.
How often should I update my change order log?
Ideally the same day the change is agreed, and never less than once a week. Memory of a verbal agreement fades fast, and the price your client remembers tends to shrink over time. A standing ten-minute review at the end of each week catches almost everything before it becomes a dispute.
