What belongs in a change order

Almost nobody loses money on change orders because the customer refused to pay. They lose it because nothing was written down, the job moved on, and six weeks later two people remember the conversation differently. By then you are not asking to be paid for work — you are asking someone to accept your memory over theirs, with the job already finished and your leverage gone.

What a change order has to contain

A change order is a small contract. It only works if it can be read months later by someone who was not there.

• What changed, in plain words — not "extra work" but "add a second coat to the north elevation".
• Why it changed. Customer request, unforeseen condition, design change, or an error. This is the line that decides who pays.
• What it costs, broken into labour and materials rather than one lump.
• What it does to the schedule. A three-day delay is part of the cost and is the part customers forget they agreed to.
• The date it was agreed, and who agreed to it.
• A signature. Typed, drawn on a phone, or an email reply that quotes the terms back — but something from them, not from you.

Raise it before the work, not after

This is the whole discipline, and it is the hard part. Before the work, a change order is a question with two acceptable answers — yes and no. After the work, it is an invoice for something the customer never agreed to buy, and their only options are to pay or to fall out with you.

It feels slower on the day. It is not. The five minutes on site is the cheapest version of that conversation you will ever have.

Small changes count

The big ones almost always get documented, because the number is frightening enough to make somebody careful. It is the small ones that leak — an hour here, a fitting there, a bit of extra prep. Individually they are not worth the paperwork. Added up across a year they are a meaningful part of what the business earned and did not bill.

The fix is not to care more. It is to make writing one down take less time than deciding whether it is worth writing down.

The trap in verbal approval

Most people do ask. They stand in the hallway, explain the problem, and the homeowner says "yes, just do it". That is a genuine agreement and it is worth very little. Nobody is lying six weeks later — they simply remember agreeing to something smaller, or they remember agreeing but not to that price, and neither of you has anything to check against.

A text message is better than nothing. A signed change order takes about the same time on a phone and cannot be remembered differently.

A short checklist

1. 1Stop before doing the work, not after.
2. 2Write what changed and why, in words the customer would use.
3. 3Price it out — labour and materials separately.
4. 4Say what it does to the finish date.
5. 5Get it signed there and then, on your phone if that is what is to hand.
6. 6Make sure it reaches the invoice. A signed change order that never gets billed is the same loss with more paperwork.

That last step is the one that quietly fails. The change gets agreed, gets signed, gets built — and then the invoice is raised from the original quote because that is the document sitting on the desk. If your change orders do not flow into the bill on their own, check the last few jobs. There is usually one.
