The status calls were driving us crazy — 20+ per day. Since Mandu automated that, my mechanics can finally work uninterrupted. Best investment of the year.

Challenge

'Is my car ready?' — 20 times a day.

The most common question in any workshop. With 12 to 15 vehicles daily, 20 to 25 such calls came in. Each took 3 to 5 minutes — the mechanic had to check the order, explain to the customer. 20 calls times 4 minutes: over an hour per mechanic, per day.

Mechanics on the phone instead of in the workshop.

The 3 master mechanics spent a combined 4 hours daily on the phone — with status updates that don't require technical expertise. Meanwhile, vehicles waited for diagnosis, parts for ordering, and customers for callbacks.

Solution

Automatic status notifications

Customers receive automatic SMS updates whenever the order status changes: vehicle received, diagnosis complete, parts ordered, repair finished, ready for pickup. No calling needed.

AI phone for remaining questions

Those who still call get real-time status from the AI. Only technical questions ('Can the turbocharger be repaired?') are forwarded to a mechanic.

Results

Mechanics finally work uninterrupted

Frank D.: 'My mechanics are mechanics, not call center agents. Since automation, phone interruptions dropped from 20 to 2-3 per day. People just don't call anymore because they already know everything via SMS.'

Customers happier despite less contact

Paradoxically, customers are more satisfied despite fewer calls. They have visibility, stay informed, and don't have to wait on hold. Google reviews now regularly mention 'great communication.'
