How to handle extra work requests without end-of-job arguments

How 'while you're here' eats your margin

You are mid-renovation and the customer says 'while you're here, could you add an outlet in the garage?' You say sure, because it is twenty minutes and you like them. Then it is the outlet, plus moving a switch, plus a look at the flickering light in the hall. By handover you have done $600 of extra work on a $4,000 job.

Now the invoice arrives and the customer is genuinely surprised. In their memory, those were small favors. In yours, they were billable work. Nobody is lying. There was just never a number said out loud, and unsaid numbers always land lower in the customer's head than in yours.

The two-minute change order

When the request comes, do three things. Say yes to considering it. Give a price before you start: 'Happy to, that outlet is $180 on top of the quote.' Then put it in writing, which can be as light as a text: 'Confirming the garage outlet at $180, added to the final invoice.' Their thumbs-up reply is your record.

This takes two minutes and changes the entire end of the job. The invoice matches what they agreed to in writing, line by line. There is nothing left to argue about, because every number was agreed before the work happened.

Price extras like small jobs, because they are

The trap with extras is quoting them from your gut while standing on a ladder, which is how a $180 outlet becomes 'ah, call it eighty'. Treat each extra as a small job with real labor and materials in it.

This is where a written estimate helps even at small scale. DeimLead can build you an estimate builder from one sentence, something like 'an estimate builder where I pick line items and it totals labor and materials'. It lives at a link, so you fill it in on your phone at the job, show the customer the total on screen, and get the yes right there. Your line items come from your own prices, so the garage outlet costs the same whether you quote it Monday morning or Friday at 5pm.

Saying it without the awkwardness

Owners skip the written step because it feels like distrust toward a nice customer. Flip the framing: paperwork protects them too. Try 'I always put extras in writing so my invoice never surprises anyone.' Customers hear that as professionalism.

The one situation to hold firm on is 'just add it to the bill'. That sentence feels like agreement but contains no number. Answer with the number: 'Will do, it will be $180, that work for you?' Ten seconds now, or twenty minutes of invoice argument later.

Adopt one rule this week

No extra work without a number said out loud and a one-line text confirming it. Hold that rule for a month and end-of-job arguments mostly disappear.
