This template reflects standard change order practice for high-ticket service businesses as of September 2026 and is due for review by September 2027.
A change order only protects a high-ticket service business if it captures four things before work continues: the exact change, the cost impact, the schedule impact, and a signature — and it needs to work whether that signature happens on a clipboard, in an email, or with a text reply. Below is a free two-page PDF (a one-page Change Order plus a one-page Change Order Log), a copy-paste email version, and a text/WhatsApp version — built to get signed in the field in under two minutes, not filed away and forgotten.
Change Order Template — 2 pages, print-ready
Page 1: Change Order · Page 2: Change Order Log
Download Free PDFPage one is the Change Order itself. Page two is a Change Order Log — one line per change, so nothing gets approved verbally and then forgotten by invoice time. Print it, keep a stack in the truck, and fill it out on-site before the next task starts.
Four fields carry the entire document. Everything else is context.
Description of the change — what's being added, removed, or changed from the original scope. Specific, not vague: “replace damaged subfloor, approx. 40 sq ft” — not “extra work in kitchen.”
Cost impact — labor, materials, and subcontractor cost, broken out, with a total change amount. A single lump number invites the same dispute a vague scope invites.
Schedule impact — days added, if any. Clients remember price changes. They forget timeline changes were ever discussed unless it's written down next to the number.
Signatures — contractor and client, both, before work on that item continues. This works even though the crew is standing in a half-demoed hallway with thirty seconds before the next task starts — because the two-minute version below is built for exactly that moment.
The line that matters most is the one most templates skip: work will not proceed on this item until both signatures are complete. Without it, a verbal “yeah, that's fine, keep going” gets treated as approval — and a verbal yes is exactly what turns into “we never agreed to that” at final billing.
Not every change gets signed on paper. Use whichever fits the moment — the goal is a clear, specific yes, not a specific format.
Email version — copy and send:
Subject: Change Order #[CO#] — [Project Name]
Hi [Client Name],
While working on [task], we found/were asked to [reason for change]. Here's what that means:
Change: [description]
Cost impact: $[amount] (Labor $[x], Materials $[x], Sub $[x])
Schedule impact: [X] days added
New contract total: $[new total]Work won't continue on this item until we have your sign-off. Reply “approved” to this email, or let us know if you'd like to discuss first.
[Your Name]
Text / WhatsApp version — copy and send:
Change order: [brief description] — adds $[amount] to the project (new total: $[new total]). Reply YES to approve. Work pauses on this item until we hear back.
A specific text reply to a specific number is a real acceptance, not an informal one — the same way a signature is. The format doesn't determine whether it holds up; the specificity does.
A single signed change order is easy to keep track of. Five of them across three active projects, over six weeks, are not — and the ones that get lost are never the big ones. They're the $400 electrical add and the $650 tile upgrade, approved in a hallway, never entered anywhere, gone by the time the final invoice gets built.
The log is one line per change order: number, date, description, amount, who approved it, whether it's signed, and its status. At closeout, the total on that log should match the difference between the original contract and the final invoice. When it doesn't, that gap is exactly the unbilled work — found before the invoice goes out, not after the client's already paid and moved on.
The reason to keep this on paper next to the signed change order, not just in a project file somewhere, is the same reason the change order itself needs to be filled out on-site: the record has to exist at the moment the decision gets made, or it competes with memory for accuracy — and memory loses.
A signed change order that never makes it into the log is a disconnected piece of data — accurate in the moment, invisible by the time it matters. The change needs to flow from the field, into the log, into the final invoice, without anyone having to reconstruct it from a stack of paper or a text thread three weeks later. That's the difference between a change order system and a change order that happened to get signed once.
TIM is Digital Labor — a business operating system for US service businesses with 1 to 15 employees running high-ticket projects. TIM handles lead follow-ups, professional quotes, project tracking, payment requests, and client communication — including the change orders that currently live on paper in a truck or buried in a text thread. The administrative cost of manually reconciling a change order log against a final invoice runs on top of the $4,000 to $5,500/month a business already pays for someone to do it by hand — before counting the ones that never made it onto the log at all.

Do I need a lawyer to write a change order?
No. A change order needs four things to hold up: a specific description, the cost impact, the schedule impact, and a clear signature or reply before work continues. The template above covers all four in a format built to be filled out on-site.
Is a text message change order legally valid?
A specific text reply to a specific offer — a clear description and a clear amount — can function as a real acceptance, the same way a signature does. What matters is the specificity of what was agreed to, not the format it arrived in.
What happens if a change order isn't signed before work starts?
The work proceeds on the strength of a verbal agreement, which is exactly the situation that turns into “we never agreed to that” at final billing. The fix is refusing to proceed on the changed item until the two-minute email or text version above gets a clear yes.
