Case Study 01
How Sydney Auto Centre cut admin time in half and grew RO value by 19%
Sydney Auto Centre · Parramatta, NSW
Workshop size
7 bays · 6 technicians
The challenge
The invoicing process at Metro Motors was fragmented — technicians wrote job notes on paper, an admin staff member transcribed them into a spreadsheet, and invoices were manually generated each afternoon. Errors and omissions were costing 2–3 hours of rework per week.
The solution
Workshop Wrench replaced the paper workflow end-to-end. Technicians complete digital repair orders on a tablet; approved estimate lines flow directly into the invoice with correct GST treatment. The afternoon invoicing batch now takes under 20 minutes.

“Invoicing used to ruin our afternoons. Now it is done before lunch and the numbers are right the first time. The time we saved paid for the software in the first month.”
