How an appliance service network stopped missing calls and booked 42% more jobs

Forty service areas across West India, and the constraint was never technician capacity. It was a phone line that stopped answering at 7pm.
The network
The client operates an appliance installation and repair network covering 40 service areas across West India, dispatching several hundred field technicians through a scheduling app.
Demand is spiky and emotional. A customer whose refrigerator has failed on a Sunday evening is not going to wait until Monday to try a competitor.
The problem: the phone line was the bottleneck
A small central booking desk covered business hours. Outside those hours — evenings, Sundays, festival weeks and every demand peak — inbound calls rang out or went to voicemail that nobody returned quickly enough.
The network measured technician utilisation carefully and it was healthy. What it had never measured with the same rigour was how many jobs never entered the system at all, because the caller hung up and dialled someone else.
Even in hours, booking a job took a long call: confirming the appliance, the fault, the address, the service area and a slot the technician could actually make.
What changed with Quallix Assist
Quallix Assist answers the inbound line, in the caller's language, at any hour. It identifies the appliance and fault type, confirms the address, maps it to a service area, checks live technician availability and writes the booking straight into the scheduling app.
It is explicitly bounded. Warranty disputes, escalations, refund requests and anything the agent cannot confirm from the customer record get handed to a human with the full transcript attached rather than improvised.
Every promise made on the call — the slot, the visit charge, the callback — is logged against the job, so the technician arriving the next morning sees exactly what the customer was told.
Results
Missed inbound calls went to zero: every call is answered, including the ones that arrive at 9pm on a Sunday.
Booked jobs rose 42% against the same period the previous year, with no change in marketing spend and no additional booking-desk headcount. Average time to a confirmed booking settled at 11 minutes, including the calls that were handed to a human mid-conversation.
Outcome
The booking desk now handles exceptions and escalations rather than routine slot-filling, and the network's growth constraint has moved back to where it belongs: technician capacity.
As the operations head put it, the technicians were never the bottleneck — the phone line was.
