A tech who takes a repair job holds it until you both agree it's done.

When a tech accepts a repair job on a job-posting site for local service work, the clock stops. The job is his until you both coordinate and finish the work or one of you cancels. He doesn't have to race against the timer or watch the same job get offered to three other people while he's driving over.

This sounds simple, but it changes the whole flow. A tech can show up without panic. A homeowner isn't wondering if someone else is about to ring the doorbell instead. The job stays put because the system knows he's committed to it.
