Stop and Re-Quote or Finish at the Original Price: Decision Tree
Why this matters
Extra work has appeared mid-job and now you have a live choice: halt everything to renegotiate, or drive the job to completion at the price you quoted. Stop when you should have pushed through and you leave a customer with the water off and a half-open system while you talk money. Push through when you should have stopped and you either eat a scope you cannot afford or do unauthorized work you cannot bill. This is an operational call about interrupting the job, separate from the question of who ultimately pays. This tree tells you when to pull the cord.
Safety overrides the whole decision
Neither "finish" nor "stop" is allowed to leave a hazard live.
- If finishing would mean performing or certifying work you know is unsafe (undersized circuit, compromised gas connection, failing pressure boundary), you do not finish it to protect a quote. Stop.
- If stopping would leave a hazard exposed (open live conductors, gas off with a pilot to relight, water isolated in freezing conditions), make it safe before you pause, or stay until it is safe.
Once safety is handled, the choice below is about business and momentum, not risk.
The core question: what does interrupting cost right now
The job is often in a vulnerable state when the surprise hits. Weigh the cost of stopping before you default to it.
- Cheap to interrupt: the system is stable, you can restore to a no-worse condition, the customer is reachable. Stopping is easy.
- Expensive to interrupt: the water is off to an occupied home, the unit is fully open, there is no heat or no power, weather is closing in. Stopping does real harm.
A material surprise that is cheap to interrupt leans toward stop-and-re-quote. A modest surprise that is expensive to interrupt leans toward finishing and squaring up after.
Compare the two paths
| Factor | Stop and re-quote | Finish at original price |
|---|---|---|
| Size of the extra | Material, changes the ticket meaningfully | Small relative to the job |
| System state | Can be paused, restored to no-worse | Open, unsafe to leave, customer without service |
| Authorization | Customer must choose; it is their money | Trivial add, or clearly your miss to absorb |
| Trust risk | Low, if shown and documented | Low, and finishing quietly can build goodwill |
| Main danger | Leaving the customer stranded mid-job | Doing unbillable or unauthorized work |
When to stop and re-quote
- The extra is large enough that a reasonable customer would want to decide.
- It is a blocker requiring a real choice between paths.
- You can safely pause and put the site in a no-worse state while they think.
- The number is big enough that continuing without a yes exposes you to a refusal to pay.
Stopping here is not weakness, it is respecting that it is their money and their house.
When to finish at the original price
- The overage is small enough that stopping costs more in disruption and goodwill than it saves.
- The system cannot be safely or humanely left, and the extra is manageable.
- The gap is your own miss and minor - finishing quietly and eating it is cheaper than the trust hit of a re-quote on your error.
- You are nearly done and the remaining surprise is trivial.
Finishing does not mean silence. Tell the customer what you found and that you handled it inside the original price. Free work they never hear about earns nothing; the same work, mentioned once plainly, earns loyalty.
The hybrid: finish the safe minimum, then re-quote the rest
Often the right answer is both. Do the part that must not be left undone, restore the customer to a safe and functional state, and re-quote the larger discovered work as a separate, unhurried decision. This gets the house back in service without doing big unauthorized work, and it gives the customer a calm choice instead of a mid-job ultimatum.
Recap
- Safety first: never finish unsafe work, never leave a hazard to stop.
- Weigh what interrupting costs right now.
- Material and cheap to pause = stop and re-quote.
- Small or expensive to interrupt = finish, then tell them what you absorbed.
- When in doubt, finish the safe minimum and re-quote the rest.
