Part of our guide to Running an Independent Garage
Busy is not the same as successful
Many independents repeat the same mistakes for years because the workshop stays full. These patterns show up on the garage growth score long before the accountant sends the year-end figures.
Pricing and margin mistakes
- Copying a competitor's labour rate without knowing your costs
- Absorbing diagnostic time instead of charging fairly
- Discount MOTs with no plan to convert advisories to paid work
- Parts sold at thin margin to 'keep the customer happy' on every job
Fix the fundamentals in labour rate calculator guide and garage profitability guide.
Operations and customer mistakes
- Diary packed with no buffer — jobs slip and customers complain
- No MOT or service reminders — silent customer churn
- Missed calls treated as normal — each one is a booking lost
- Chasing new customers while ignoring retention
Owner mistakes
Doing every role — master tech, receptionist, buyer, marketer — works until it does not. Burnout shows as missed calls, snappy handovers and no time to review garage KPIs. Delegate, automate admin and invest in systems like AskMike AskMike Pro that handle repeatable customer work. Read running an independent garage for the full operating picture.
Frequently asked questions
- What is the most expensive mistake garage owners make?
- Undercharging for labour while overheads rise. Busy ramps mask the problem until a quiet month exposes cash flow. Fixing the labour rate often matters more than finding more customers.
- Should I offer free collection and delivery?
- Only if you cost it in or use it selectively for high-value jobs. Free miles add up quickly in fuel and driver time.
