How to Handle a Change Order Without Losing the Job (or the Margin)

The proposal was accepted, the crew is on site, and then the job changes. The wall comes open and the pipe behind it is done. The client, standing in the doorway, asks the question that decides whether change work makes you money or costs you money: 'While you're here, can you also…?' How you handle the next ten minutes matters more than the price you name.

Name it as a change, kindly and immediately

The mistake is not generosity — it is silence. Extra work absorbed without a word teaches the client that the scope is elastic, and the second change arrives larger than the first. The professional move is warm and plain: 'Happy to do it. That's outside the accepted scope, so I'll price it as a small change order and send it over for your approval before we start it.' Said in that tone, it reads as organization, not nickel-and-diming.

Price it from the same structure as the original proposal

A change order priced from structure — labor, materials, disposal, the building's access rules if it is a condo job — can be explained line by line. A change order priced as a round number from memory invites negotiation and, worse, invites the client to wonder whether the original price was built the same way. Small changes deserve the same arithmetic as big ones; that consistency is what makes a client stop auditing you.

Get the acceptance before the work, every time

• The change described in one or two plain sentences: what is added, what is not

• The price of the change itself, separate from the original total, and the new total

• Any schedule effect stated honestly: 'adds half a day' is information, not an apology

• The client's acceptance recorded before the changed work begins — typed name and timestamp, the same standard as the original proposal

Verbal approvals in a noisy kitchen are how contractors end up owning free work. 'You said it was fine' against 'I thought it was included' is a dispute with no document, and the document is the whole product.

The South Florida change-order traps

Condo buildings turn small changes into logistics: an added scope item can mean a new elevator reservation, another certificate for the association, or work pushed into a different day by the building's hours. Hidden-condition changes — the corroded pipe, the unpermitted prior work — should be photographed the moment they are found and sent with the change order, because a photo of the opened wall ends arguments that descriptions start. And in storm season, a change that extends a job can move its completion across weather nobody controls; say so in the change order's terms.

Built to take thirty seconds, not thirty minutes

QuoteMango proposals are versioned documents: duplicate the accepted proposal, add the change as its own clearly labeled group, and send it for a fresh acceptance — the original acceptance stays locked and untouched, and the change gets its own timestamped record. The contractor who documents changes this way finishes jobs with the paperwork already done, and the final invoice is a summary of acceptances, not an argument.
