Upload Past Service Invoices
Export your past customer invoices - name, phone number, vehicle model, and date of last service. That's all you need.
Hundreds of vehicles you serviced last year are due for repairs, brakes, or maintenance right now. If you don't message them, they pull into the first workshop they drive past. VoiceOffice wakes them up on WhatsApp and books them into your workshop automatically.
My job is to fill your hoists and put money into your account. Every morning numbers are shuffled into a fresh batch of 10 for lunch and 10 for commute. Skipping a batch leaves empty bays on the table.

You KNOW your database has hundreds of past vehicles
You KNOW those cars are due for oil, brakes, or cambelts right now
You KNOW following up would fill your hoists every single morning
Your mechanics are under cars, and your front desk is busy with walk-ins. Past customers go quiet — and they take their service to whatever workshop messages them first.
VoiceOffice becomes your dedicated 24/7 service advisor bringing every overdue car back to your workshop.

VoiceOffice scans for vehicles serviced 6 to 18 months ago, shuffles a daily batch of 10 for lunch and 10 for commute, and finds who needs maintenance.
VoiceOffice sends a friendly, polite WhatsApp check-in. When the owner says their car is due for service, brakes, or an oil change, your workshop gets an instant alert to slot them in.

VoiceOffice sends exactly 10 friendly messages at 12:00 lunch and 10 messages at 17:00 commute. No spam. Just genuine, polite check-ins that drivers appreciate.

"An empty hoist was costing us R3,500 every day. VoiceOffice booked 27 extra services in our first month from customers we hadn't seen in over a year."
"VoiceOffice delivered 38 service-ready vehicle owners in 30 days. Our diary finally stayed full every week without buying flyer drops or ads."
"It's like having a relentless service advisor who calls past customers every day so no job slips away to competitors."
Everything you need to know before filling your workshop diary.
Most vehicle owners forget when their car was last serviced. If you don't remind them, they wait until a breakdown or pull into the first quick-lube they drive past. An empty hoist costs R2,500 to R5,000 every single day.
No. VoiceOffice strictly follows POPIA and CPA. It sends 20 personal messages per day (10 lunch, 10 commute; 20 Saturday). If someone says 'sorted', they are instantly removed forever.
No. VoiceOffice never quotes prices. It simply asks: 'Hi Mark, your Ranger was last in with us around this time last year. Are you due for a service check-up, or are you all sorted?' Once they reply, your service team books them.
Works with any system that can export an Excel or CSV file: Auto Data, Kerridge, workshop spreadsheets, or manual lists.
Vehicle owners reply within hours. Most workshops see their first booked service within 24 hours of their first shift.
Upload a list of 20 past customers, launch a test wave, and watch overdue vehicle owners reply asking for a booking before lunch tomorrow. Zero contracts. Zero risk.
