Sample engagement
The independent garage that reclaimed 9 hours of admin a week.
Three bays. Two technicians. Paper job cards and Sage.
An independent garage ran on paper job cards and Sage. Admin hours per week: ~14 between owner and admin staff. Customer authorisation took 30+ minutes per job, often holding up bays. We shipped a workshop app integrated with Euro Car Parts and Xero. Three months in: admin time 14 → 5 hrs/week, customer auth time 30 mins → 4 mins, parts margin up 2 points from rate-shopping.
How we measure: Admin time tracked via self-report and timesheet audit, auth time measured from extra-work-found to auth-signed (n = 240 jobs pre/post), parts margin measured against ledger pre/post.
