“While you’re here, could you just…” is the most expensive sentence in the trades.
TL;DR Write exclusions into every quote. Price every change before doing it. Get approval in writing, and a text message counts. The habit is worth more than the paperwork.
Where the money actually goes
Scope creep is rarely one big thing. It is twenty small ones.
- The extra fitting while you have the wall open.
- The second outlet since you are already there.
- The “quick look” at something unrelated.
- The re-do because they changed their mind.
- The advice call three weeks later.
- The cleanup of somebody else’s mess.
Each feels too small to charge for. Together they are frequently 10 to 20% of a job, taken entirely from your margin.
Define scope by writing exclusions
Every quote lists what is included. Almost none list what is not, and that is where the disputes live.
Add this section to every quote
Included: removal of existing unit, supply and install of new unit, connection to existing supply, testing, and removal of old unit.
Not included: any repair to existing pipework found to be defective, drywall repair, painting, electrical work beyond the existing connection, or asbestos handling if present. Any of these will be quoted separately before proceeding.
Writing the exclusions is the actual work. It forces you to think about what you might find, and it converts a future argument into a paragraph they already read.
Spot creep early
The tells
- “While you’re here…”
- “It’s only a small thing.”
- “The last guy would have…”
- “I assumed that was included.”
- A request that arrives after the quote was accepted.
- Anything requiring a trip to the supplier.
The moment to act is at the request, not at the invoice. A charge that appears on the final bill without prior discussion produces disputes and bad reviews, even when you are entirely right.
The response, said kindly
Do not refuse. Price it.
Yes, we can do that. It is about $X and adds roughly an hour. Want me to add it on?
Three things this does. It says yes, which protects the relationship. It attaches a number, which makes it a decision. It asks for approval, which creates the record.
Most people say yes. The ones who say no were never going to pay for it anyway, and you just avoided doing it for free.
Never say “do not worry about it” for anything over a few minutes. That is the habit that costs you a fifth of your margin, and it also teaches that customer that scope is negotiable.
The change order itself
Keep it light or you will not use it.
Minimum viable change order
- What the change is, in one sentence.
- What it costs.
- What it does to the timeline.
- Their approval.
A text message is a valid record.
Found the shutoff valve is seized. Replacing it is $140 and adds about 45 minutes. Ok to proceed?
“Yes go ahead”
Screenshot it, attach it to the job. That is a change order.
For larger changes, use a proper document with a signature. Most field service software has this built in and it takes two minutes on a tablet.
The rule that makes it work
Get approval before doing the work. Every time. No exceptions.
The temptation is always to do it and mention it later, because stopping feels awkward and the job is right there.
Doing it first removes their choice, which is what turns a reasonable charge into a dispute. It also removes your leverage, because the work is already done.
Stopping for two minutes to send a text is the entire discipline.
Pricing changes
Do not discount them just because you are already on site.
You can price them slightly differently, and here is the honest logic. You save the travel and setup, so a small efficiency saving is fair and it feels generous. But the work still costs labour and materials, and it still displaces something else in your day.
A workable approach. Standard rate for the work, no travel charge, stated as such.
That is $140. Normally there would be a call-out on top but since we are already here, just the work.
That framing earns goodwill without costing margin.
Handling “I thought that was included”
This is the conversation the exclusions section exists to prevent.
I can see why you would think that. The quote covers [X] and lists [Y] as separate, here on page one. Happy to do it now for $Z, or leave it if you would rather.
Calm, reference the document, offer the choice. No argument about what was meant.
If your quote did not say, that is on you. Absorb it once, then fix your quote template that day.
The habit, not the paperwork
The system is three steps and it takes minutes.
- Exclusions in every quote. Write them once as a template per job type.
- Price every request at the moment it is made.
- Get a yes in writing before starting.
None of this requires software. It requires stopping for two minutes instead of doing the favour.
Add an exclusions section to your quote template today. Then track for one month how many change requests you price rather than absorb. Most people find the number surprising, and the revenue is money they were already earning and giving away.
