A foreman gets a call: “While you’re here, move those lines six feet.” The crew can do it. The work may only take a few hours. But without a documented change order, that small request can become labor, material, and equipment you never get paid for.
For subcontractors, change orders are not office paperwork. They are how you protect the margin on work that was not included in the original scope. The problem is not usually that a crew cannot identify extra work. The problem is getting that information from the field to the office, approved by the right person, and billed before the job closes.
Why Change Orders Get Missed
Most lost change order revenue starts with a fast-moving jobsite. A superintendent asks for a different layout. Existing conditions do not match the plans. Another trade causes damage or blocks access. The crew is told to keep moving, so they do.
That response can be good for the schedule and the customer relationship. It becomes expensive when nobody records what changed, who requested it, and what it cost. By Friday, the details are fuzzy. By the end of the month, the work may be buried in regular job costs.
Spreadsheets and paper tickets make this worse. The foreman may text photos to one person, hand a note to another, and mention the extra work during a call. The office then has to piece together labor hours, material receipts, equipment use, and approval status. That is not a process. It is a chase.
The goal is simple: make it easy for the field to flag extra work immediately and easy for the office to turn that information into a priced, documented request.
A Simple Change Order Process That Holds Up
The best process is the one your foremen will actually use at 6:30 a.m. on a busy site. It should take minutes, not a long form and a dozen emails.
1. Flag the extra work before the crew starts
When the scope changes, the foreman should create a quick record right away. That record needs the job name, location, date, a plain-language description of the requested work, and the name of the person making the request.
Photos matter. Take wide photos to show the area and close photos to show the condition, conflict, or revised layout. If a concrete crew finds unsuitable subgrade, for example, photos and a short note can show why additional excavation and stone are needed.
This is not about writing a legal brief in the field. It is about preserving the facts while they are fresh.
2. Separate authorization from approval
A superintendent may direct your crew to proceed. That does not always mean the owner or general contractor has formally approved the price. Your team needs to know the difference.
Documented direction to proceed can support your position, especially when stopping work would delay the job. Still, do not treat it as a blank check. Mark the work as pending approval and get written confirmation of the agreed pricing as soon as possible.
Your contract controls the required notice, timing, and approval path. Some contracts require written notice within a set number of days. Others require a signed change order before work begins, except in an emergency. Follow those requirements on every job, even when the request comes from someone you trust.
3. Capture real costs, not estimates from memory
A change order price should account for more than a few added labor hours. Track the actual labor, materials, equipment, trucking, disposal, subcontractors, supervision, and schedule impact tied to the change.
Schedule impact is where many subs leave money on the table. A small change can require a return trip, extra mobilization, overtime, remobilization, or crews waiting for another trade. If the change pushes your sequence, the cost may be much bigger than the task itself.
Use your normal estimating rates where they apply, but compare them with the job conditions. Tighter access, night work, occupied spaces, and phased work can change the price. A clear quote protects both sides because it sets expectations before the bill arrives.
4. Send a clean request that answers the obvious questions
The person reviewing a change order should not have to hunt for the reason, price, or backup. Keep the document clear. State what changed, why it changed, the added or deducted amount, and any effect on the schedule.
Attach the field notes, photos, sketches, time records, material tickets, and customer direction that support the request. If the scope is still being priced, send a notice first and follow with the final amount. Silence is not approval, but early notice prevents a surprise later.
5. Track the status until it reaches the invoice
Sending a request is not the finish line. Every change should have a visible status: identified, priced, submitted, approved, rejected, completed, or billed. Someone in the office needs ownership of follow-up.
A weekly review works well for most subcontractors. Look at every open item by job and ask: What is waiting on pricing? What is waiting on customer approval? What extra work has been completed but not invoiced? That last question often finds cash that would otherwise be lost.
What a Strong Change Order Record Includes
A good record makes it hard for anyone to say, “We never discussed that.” It should connect the jobsite event to the money request without creating a paperwork burden for your crew.
For each change, keep these core items:
- The original scope reference and a clear description of the added, deleted, or revised work
- The reason for the change, such as revised plans, concealed conditions, owner request, or trade conflict
- The person who requested or directed the work, plus dates and any written communication
- Supporting photos, daily logs, sketches, time entries, material tickets, and equipment records
- The price, schedule impact, approval status, and invoice reference once billed
The exact format can vary by trade. An electrical contractor may need revised panel schedules and conduit routing. A landscaping contractor may need site photos, plant substitutions, and delivery tickets. A roofing contractor may need photos of concealed deck damage and a record of weather conditions. The principle stays the same: show what happened, show what it cost, and show who knew about it.
Common Mistakes That Cut Into Profit
The first mistake is waiting until the end of the job. By then, people have moved on, photos are missing, and your customer may argue that the work was included. Raise the issue while the condition is still visible.
The second is accepting verbal approvals without confirming them. A quick email or system note that says, “Per our conversation, we will proceed with the added work at the quoted amount,” creates a much better record. If pricing is not approved, say so clearly.
The third is using vague descriptions. “Extra work” does not explain anything. “Remove and replace 80 linear feet of 4-inch conduit due to revised structural steel location” does. Specific language reduces back-and-forth and makes billing easier.
The fourth is forgetting deductions. If a revised plan removes part of your original scope, document the credit just as carefully as an added cost. Fair, transparent change management builds trust and makes your added requests more credible.
Finally, do not bury approved work in a later invoice with no backup. Bill approved change orders separately or identify them clearly. Your customer should be able to match the invoice line to the approved request in seconds.
Make the Field-to-Office Handoff Easy
Change order control breaks down when the field has one system and the office has another. Your foreman should not need to call in hours, text photos, save paper tickets, and remember details for a meeting days later.
A field-friendly construction platform can put job photos, daily logs, crew time, equipment use, materials, and documentation in one job record. With SimplySub, the office can see the information coming from the jobsite while the details are still current, then use it to price and follow up on added work.
The technology matters less than the habit. Build a clear rule: when the scope changes, document it before the crew moves on. Give foremen a fast way to do that, and make sure the office responds quickly. If the field thinks reporting extra work creates more hassle than it is worth, the details will stay in someone’s head.
A clean change order process does more than prevent disputes. It gives your crews confidence to respond to the job in front of them, while giving your business a fair chance to get paid for every legitimate change. The next time a customer says, “Can you just take care of that while you’re here?” your team should know exactly what to do. See how SimplySub can help by scheduling a demo.
