Two jobs that used to need two apps and a phone call now happen in one place: picking up work, and answering the customer about it.
A Pool of Available Work
Unassigned jobs appear in a pool that drivers accept from, so dispatch does not have to allocate every job by hand.
Answer the Customer Directly
WhatsApp conversations are handled in the same app, so the person doing the job can answer the question about it.
Complete or Report a Failure
Completing a job and reporting a failed attempt are both explicit actions, so an unsuccessful visit is recorded rather than left open.
