Change Order Management Software for Subcontractors

Change order management software lets a subcontractor price and sign extra work on a phone before the work starts, so less of the job runs on a verbal OK. The foreman captures the change on site, the office prices it, the general contractor's super signs it, and the final copy lands in the job file.

This guide is for electrical, plumbing, mechanical, drywall and concrete subs, and for small GCs. It sits beside our guides to AI for small business and to AI for Kansas City construction companies, which covers the office side of change orders. For billing a signed change, read general contractor invoices.

What change order management software does in the field

Change order management software turns the moment a super asks for extra work into a signed record before anyone picks up a tool. The foreman records a voice note and photos, a draft comes back with the scope written up, the office prices it, and the general contractor's super signs on the phone.

Verbal OKs go unpaid for plain reasons. The super who asked moves to another job, and the scope gets remembered two ways. By billing time, nobody can say what was agreed. A signed change with photos, a time stamp and a price puts it on paper while everyone still remembers the wall.

Good change order software handles both kinds of change. A lump-sum change carries one agreed price for a defined scope, such as six added outlets. A time-and-material change is signed with your rates on it, and the crew logs hours and material against it. Options a client picks before signing are a different job, so see estimating software for remodeling.

Why do paper forms and generic apps leave gaps?

Paper forms and generic apps leave gaps because a form only helps if it gets signed before the work, and the tools rarely make that easy. A pad in the truck gets wet, a shared spreadsheet has no signature, and a general e-sign app knows nothing about the job, the price book or the next bill.

Even construction change order management software sold off the shelf falls short in four places. New shells often have no signal, so the app stalls. Edits leave no history, so nobody knows which price the GC saw. Fields such as days added and a reason code are missing. And the export rarely fits your billing tools.

What we build: a change order app, screen by screen

We build a change order app around your crews, your price book and the general contractors you work for. It is a full web application that foremen use on their phones and the office runs at a desk, with one screen for each step from the first voice note to the line on the next bill.

• Capture. The foreman picks the job, records a voice note, takes photos and marks the spot. The app stamps the time, and with no signal it all waits on the phone.
• The draft. AI writes the description and the labor and material lines, and leaves every price blank.
• Pricing. Your office prices each line from your price book or your time-and-material rates. People set those rates.
• Schedule impact. Days added, if any, and a reason code such as owner request or hidden condition.
• Signature. The GC's super signs on the foreman's phone or from a link, with name, date and time kept. Links go by email, or by text to supers who agreed to get texts, and anyone can opt out.
• The signed copy. A PDF goes to the GC, your office and the job file.
• The job log. Every change on the job: pending, approved, rejected or billed.
• Billing. Approved changes appear as their own lines on the next invoice or pay application.

We offer plans that give you either the right to use the software we build or full ownership of it. Your change orders, photos and logins stay with your company under both. The Admin Agent follows up on the paperwork. It reminds the GC's super about any change still waiting for a signature and keeps the job log current. Your project manager approves every price before a draft goes out, and the GC or owner signs before your crew starts.

How do we build and test a change order app?

We build it from a written spec of how your change orders work, then test it with one foreman on one real job before other crews use it. The spec covers the form's fields, who prices, who may sign and how an approved change reaches the bill, and you mark it up until it matches your shop.

Before your other foremen pick it up, five things must work on the pilot job.

1. Photos taken in a basement with no signal sync later with their original time stamp.
2. The draft leaves every price blank until a person fills it in.
3. A change cannot be marked approved without a signer's name, date and time.
4. An edited price shows who changed it, when, and what it said before.
5. An approved change lands once, and only once, on the next pay application draft.

We also connect the app to the accounting or job cost software you already run, so a signed change reaches job cost without being keyed in again.

This is an illustration, not a customer story. Esteban runs crews for a small electrical sub. On a tenant build-out, the GC's super asks for four extra floor boxes in a conference room. Esteban records a voice note and three photos. The office prices the draft, the super signs on Esteban's phone before lunch, and the change rides on that month's pay application as its own line.

What stays with your PM and office?

Pricing, signing and every call about money stay with people. Your office prices each change, the GC or owner signs it, and your project manager decides what happens when nobody will approve it. The app records and reminds, and it never sets a price, marks a change approved on its own or tells anyone what the contract means.

When the super says go ahead but will not sign, your contract sets the options. Some let you wait for a signature, and others require you to keep working under written notice. Your PM and attorney decide. The app can draft that notice, but sending it is your call, and often your attorney's. Liens and disputes go to your attorney too. A record of the request helps, but it does not make a verbal OK binding or promise that anyone pays.

Same team. Same jobs. More capacity.

Change orders on Kansas and Missouri jobs

Kansas City subs work under two states' payment laws, and both tie payment to the terms of the contract. That makes the signed change order, with its price, part of the paper trail behind every pay request. How a change must be made and signed comes from your contract, and your attorney can tell you what yours requires.

On the Kansas side, Kansas's private construction payment law (opens in a new tab) says the parties must make every payment under the contract's terms. Its payment deadline applies only to a timely, properly completed and undisputed request. An unsigned change is exactly the kind of line that gets disputed. Under the Kansas act's scope section (opens in a new tab), that law leaves out single-family homes, small multifamily buildings and public works. In Missouri, the state's private prompt pay statute (opens in a new tab) requires scheduled payments under the contract's terms and leaves out small owner-occupied homes. A person sets each job's state and type when it is created.

Frequently asked questions

What is change order management?

Change order management is the process of capturing, pricing, signing and tracking changes to a contract's scope after work begins. For a sub, every extra the GC asks for gets written up, priced by your office and signed before the crew starts, then logged until it is billed.

What is a change order in construction?

A change order in construction is a written agreement that alters a contract's scope, price or schedule after signing. It names the added or removed work, the price or how it will be set, any extra days, and who signed it and when.

What is a field change order?

A field change order is a change written up on site, usually when a super or inspector asks for something the drawings did not show. It captures the work, the location and photos right away, and it still needs a price and a signature before the crew starts.

How do you write a change order?

Describe the work in plain words, note where it is and why it changed, and list the labor and material lines. Then add the price or your time-and-material rates, any extra days and a signature line with the date. Get it signed before the work starts.

What is a change order log?

A change order log is a running list of every change on a job, with its description, price and status. It shows which changes are pending, approved, rejected or billed, so the office sees what still needs a signature and what is ready for the next invoice.
