Verbal change orders: why "he told me to go ahead" costs contractors money
A verbal go-ahead is not worthless — but valid and provable are two different things. The problem is almost never that the client didn't agree. It's that the argument happens at invoicing, weeks later, and there is nothing to point at.
This is general information, not legal advice. Whether a verbal change binds depends on your contract and where you work, and many construction contracts contain a clause requiring changes to be in writing. If real money is at stake, ask a lawyer in your state.
How the dispute actually happens
It rarely looks like a client lying. It looks like this:
- You open something up and find a problem. You call the client from the job.
- They say "yeah, just do what you need to do."
- You do the work. You're busy. The next job starts.
- Six weeks later the invoice arrives and it's $2,400 more than the quote.
- The client remembers agreeing to the work. They do not remember agreeing to that number — and they may be telling the truth, because the number was never said out loud.
That gap — approved the work, never approved the price — is where most of these end up. Nobody is lying and there's no way to settle it.
What actually counts as proof
The useful test: would a stranger reading it agree the client approved this work at this price?
| What you have | Holds up? | Why |
|---|---|---|
| A note in your own job records | No | You wrote it. It records your intention, not their agreement |
| "He said go ahead" from memory | No | Their memory is different and equally sincere |
| A text from the client saying "go ahead" | Partly | Shows agreement to the work — usually not to a price |
| An email from the client agreeing to a stated amount | Yes | Dated, in their words, with the number in it |
| A signed change order | Yes | The standard for a reason |
| A timestamped approval both sides can see | Yes | Neither party can edit it after the fact |
The pattern: proof is something the client created or agreed to, dated, with the work and the price in it. Anything you wrote yourself fails that test no matter how detailed it is.
The real reason contractors skip it
Not laziness. Getting written approval mid-job is genuinely awkward:
- It slows the job down. You're standing in the crawlspace; they're at work. Formal paperwork means waiting.
- It changes the tone. Producing a document after a friendly phone call can feel like you don't trust them.
- It happens five times on one job. Doing a formal change order for every $180 item is not realistic.
Those are fair objections, and any advice that ignores them gets ignored. The answer isn't more paperwork — it's making the record take seconds.
What to do instead, free, starting today
None of this needs software:
- Send a text or email before you do the work, with the number in it: "To replace the subfloor in the back bedroom it's an extra $2,400 — reply yes and I'll crack on." Their reply is your record. This takes twenty seconds and is the single highest-value habit here.
- Always put the price in the message. "Go ahead" on unstated money is the thing that fails later.
- Send it from the job, before starting, not from the office that evening. Approval after the fact is much weaker and feels worse to receive.
- Set a threshold with yourself. Under $150, absorb it or note it. Above, always get the reply. Deciding once stops you re-deciding on every job.
If you use field service software, check whether it records client approval on added work or only lets you edit the total. Jobber, for example, has no change order feature — its documented workaround is editing line items and adding an internal note, which fails the test above.
If you want the record without the friction
mossbench is built for exactly this. You raise the change order, your client approves it on a link with no login or app, and only after they approve does the work write itself into your Jobber job. Who approved it, when, and for how much is kept as the record.
$29/month flat, and the first three change orders are free with no card, so you can watch a client actually approve one before deciding.
Straight with you: it's new and has no other customers yet, and it only works if you run jobs in Jobber. The text-message habit above is free and solves most of this. This is faster and keeps the proof in one place.
Related questions
Is a verbal change order legally binding?
Sometimes, depending on your contract and jurisdiction — and many construction contracts specifically require changes in writing. But binding and provable are different problems, and it's the second one that costs you. Ask a lawyer in your state if the amount matters.
Can I invoice for work the client approved verbally?
You can invoice. Whether you get paid without a fight is the question, and with nothing in writing it comes down to the relationship.
What if the work is already done?
Ask for confirmation in writing now, referencing the conversation and the amount: "Just confirming the extra $2,400 for the subfloor we discussed on the 14th." A reply agreeing is far better than nothing, and people often confirm honestly when asked plainly.
