Appliance repair is a parts-on-the-truck business. Your technician needs to know the brand, model, and symptom before he leaves the shop — otherwise he shows up, diagnoses the problem, drives back to grab a $14 part, and burns a billable hour. The phone intake either captures that info or it doesn't.
Most independent appliance shops have a one-person dispatcher who answers between bookkeeping and parts orders. Calls during lunch and after hours roll to voicemail. The caller — already mad about a broken washer — calls the next shop on Google and books with whoever has next-day availability and picks up the phone.
A $400-600 a month answering service takes a message but doesn't capture brand and model. Your tech calls back the next morning, the customer doesn't remember the model number, and the truck rolls without the right parts.
OnCall captures what your tech needs in the call: appliance type (fridge, washer, dryer, dishwasher, oven, microwave), brand, model number (if the customer can read it), age, the symptom in the customer's own words, and warranty status. It books the visit on your calendar and texts the work order to the tech with all of it included. See pricing — most pilots run $60-100 a month in usage.
