A plumbing dispatcher makes the same decision several times a day: an emergency has arrived, somebody has to take it, and taking it means a customer who was promised an afternoon slot is going to be moved. Software helps with that decision or it does not, and almost everything else in a plumbing dispatch product is secondary to how well it supports that one moment.
Who is nearest is the least interesting question
The useful questions are who is qualified, who can leave their current job cleanly, and whose remaining customers are least damaged by the disruption. The last of those needs the board to remember which customers have already been moved this week, which is exactly the fact a calendar does not hold.
The second time is what causes complaints
Moving a customer once is usually forgiven, particularly if they are told early. Moving the same customer twice is what turns into a review. A board that shows a move count against each job makes this visible at the moment of the decision rather than in a complaint a week later.
What each emergency displaces
On the worked example this site publishes, a job invoices $285 and a technician completes 5.2 a day. An emergency that consumes two slots displaces roughly $570 of planned work, which may well be worth doing and is worth knowing. Businesses that hold two slots a day open pay for them in exactly this arithmetic.
Tell the displaced customer before they ring
The cost of a moved appointment is much lower when the customer hears it from you at ten in the morning than when they ring at three. Automated messages make that routine, and they are regulated: calls and texts to customers sit under the Federal Communications Commission rules, so consent and an opt out are part of setting it up.
Questions people ask about plumber dispatch software
How many emergency slots should we hold?
Look at how many arrived each day last month rather than guessing. Most businesses find the honest number is one or two and they were holding none.
Should the newest technician take emergencies?
That is a commercial and a safety judgement. What the board can do is make the qualification constraint visible so it is a decision rather than an accident.
Does the software rank who should go?
It shortlists. Which customer to disappoint is a judgement about your business, and dispatchers make it better than rules do.
