Most unpaid extras were approved enthusiastically — verbally. The gap between “yes, do it” and a signature is where contractors lose money. Closing that gap on-site is a process, not luck.
1. Set the expectation at contract time
Put one sentence in your original contract: “Any change to the scope of work requires a signed change order before the work begins.” Now a change order isn’t you being difficult — it’s you following the process the customer already agreed to.
2. Stop when the scope changes
The moment you find hidden damage or the customer asks for more, pause that part of the work. Continuing “to be nice” destroys your leverage — once the work is done, the customer is deciding whether to pay for the past, not approving the future. Approving the future is psychologically much easier.
3. Show, then price — in front of them
Walk them to the problem or pull up the photo. Then build the price where they can see it: materials, labor, any credits. Transparent line items read as honesty; a single mystery number reads as a shakedown. If you use ScopeProof, this is the editor screen — quantity × price, auto-totaled, no calculator fumbling.
4. Make signing effortless
Don’t say “I’ll write this up tonight.” Every hour between the yes and the signature is decay. Hand them your phone: the change order is on screen, line items visible, and they sign with a finger. It takes less time than making the coffee they offered you.
5. Leave the paper trail immediately
Email or text the signed PDF before you leave the driveway. The customer having their own copy, instantly, does two things: it feels professional, and it eliminates “I never saw the final version” from the vocabulary of the dispute that now won’t happen.
What the signature should capture
A name scrawled on a paper margin is weak evidence. A proper capture records the drawn signature, printed name, date and time, and ties them to the exact line items approved. ScopeProof records all of that and locks the change order — signed documents can’t be edited, only amended by a new revision, which is exactly what a court or an insurance adjuster wants to see.
Hand them your phone, get the signature
ScopeProof was built for exactly this moment: price the change in front of the customer, hand over your iPhone, and they review and sign in seconds. Name, date, and time recorded — signed PDF sent before you drive off.
