The Client

A 3-bay independent repair shop with 2 full-time mechanics and a part-time receptionist. They were losing customers to dealerships with 24/7 booking systems and dealing with constant phone interruptions during busy repair work.

The Challenge

Lost Revenue from Missed Calls

The shop missed 30-40% of incoming calls during busy periods, typically 10am to 3pm. Each missed call was a potential $200-800 service booking.

An estimated $2,500-5,000 in lost monthly revenue from calls that never reached the receptionist.

No-Show Appointments

20-25% of booked appointments resulted in no-shows, wasting valuable bay time.

Each no-show cost roughly $150-250 in lost revenue plus staff time.

After-Hours Inquiries

Customers calling after 5pm or on weekends went straight to voicemail. Most booked with competitors who answered first.

An estimated 30% of potential customers lost to faster-responding competitors.

Manual Scheduling Conflicts

The part-time receptionist juggled phone calls, walk-ins, and paperwork. Double-bookings and frustrated customers were common.

Customer satisfaction issues and inefficient use of receptionist time.
