Change Orders: How to Stop Working for Free
Every small jobsite favor burns through your profit margin if it is not documented and billed. Here is how to handle change orders so you get paid for every hour worked.
The Verbal Agreement Trap
You are running conduit, framing a wall, or hanging drywall when the customer walks over and asks for an extra outlet, another recessed can, or moving a framed doorway three inches to the left. You want to be helpful and keep the job moving, so you say yes, nod, and get right back to work. At final billing, they act surprised by the charge or claim they assumed small adjustments were included in the base proposal.
Every trade contractor has absorbed real money this way. You tell yourself it is just twenty minutes of labor or thirty dollars in fittings from the truck. By the time final punch lists arrive, five small favors have burned through several days of unbilled crew labor, wasted materials, and schedule delays you absorbed for nothing.
The minute work diverges from your original signed scope, you are performing extra work. If you do not pause to document those changes on paper immediately, you are essentially volunteering your crew's labor and donating materials straight out of your operating margin.
Put Down Tools Until It Is Signed
A change order is not an awkward confrontation; it is a routine, professional amendment to your contract. When a customer asks for alterations or additions, let them know immediately that you can handle the request, but that it requires an adjustment to the contract price and the timeline. Do not start work on that modification until the agreement is clear and written.
Avoid relying on casual text messages, thumbs-up emojis, or verbal approvals shouted across a busy jobsite. Send a concise change order document that specifies the exact work to be performed, the total cost, and the schedule adjustment. Keep tools off that specific task until the property owner signs.
If a client hesitates or refuses to sign a written agreement for added work before you do it, that tells you they never intended to pay for it once completed. A fair, honest customer has no objection to signing for additional work and value they asked for.
Price the Time, Not Just the Materials
Contractors regularly undercharge on change orders because they only tally the direct material receipts. They forget the supply run across town, the time spent revising project layouts, the permit revisions, and the disruption to the trade scheduled to come in behind them.
Every change order must reflect materials, fully burdened labor hours, your overhead and profit margin, and a firm schedule adjustment. If rerouting plumbing or moving an HVAC duct delays the drywall crew by two days, state those two extra days plainly in writing so the customer cannot hold you to the original completion deadline.
When you encounter concealed jobsite conditions—such as rotted subfloor under an old shower pan or ungrounded wiring hidden behind plaster—stop and photograph the issue thoroughly before disturbing it. Clear photos prove the condition was unforeseen, not caused by your crew, and justify the change order to fix it.
Establish the Rules Before Demo Day
You win or lose the change order battle before work ever begins. Your standard contract should contain a clear change order clause stating that no altered, additional, or non-scope work will be performed without a written agreement signed by both parties that details the cost and schedule impact.
Statutory rules and licensing regulations governing written home improvement contracts and change orders vary widely across states and municipalities. Certain jurisdictions require specific statutory wording, mandated font sizes, or strictly prohibit verbal change orders. Confirm your contract terms with local legal counsel to ensure compliance in your area.
Review this clause with the property owner during the pre-construction walkthrough. Tell them plainly: when changes come up during construction, we are happy to make them, but we always price them and put them on paper first. Setting that ground rule early prevents disputes when changes inevitably happen.
Collect Payment Before the Final Draw
Waiting until the final draw to bill change orders ruins your cash flow and gives away your leverage. Once the work is finished and the customer is using the space, they have much less incentive to pay quickly. They are far more likely to nitpick punch list items or dispute charges when looking at a large final invoice.
For smaller adjustments, collect payment upfront or bill the amount directly into the very next progress milestone. For major scope additions, treat the change order like a mini-contract: require a deposit to cover materials and mobilization before dispatching crew members to execute the work.
Keep your change order balance sheet current throughout the job. Never allow unbilled work to stack up until the end of a project, or you will find yourself financing the client's design changes out of your own profit margin.
