Dispatch, supervisors and accounts on one number
A Kuwait home services company usually runs on a dispatcher's phone, a WhatsApp group with the technicians and a spreadsheet. A customer in Jahra asks for an AC service while the dispatcher is on another call, and a competitor answers first. Booked customers ring again and again to ask where the technician is, a team drives to Mangaf to find nobody home, and the payment is chased by phone a week later. In summer, when every AC is running flat out, all of it breaks at once.
Today the job details sit in a technicians' WhatsApp group and the customer chats sit on the dispatcher's phone. In a shared inbox the dispatcher owns new requests and assigns each job, the supervisor for each area sees the chats for their jobs, and accounts picks up anything about payment. Internal notes carry the address, access instructions and what was fixed last time, so customers don't have to repeat themselves and technicians don't hand out personal numbers.
