What it is
An on-site service for commercial and industrial scales: fixing faults, adjusting and calibrating with test weights, and providing calibration records or certificates. You travel to deli counters, grocery stores, farms, warehouses, labs and factories.
Your first three steps
- Contact your state weights and measures office to ask what registration or licensing service technicians need for commercial scales
- Price out a set of calibrated test weights, basic tools and spare parts, and ask suppliers or manufacturers about technician training
- Visit local delis, grocers, farms and warehouses to offer a free scale check and ask who currently services their scales
Who pays
Grocery stores, delis, butchers, cannabis dispensaries, farms, packaging and shipping operations, small labs and light manufacturers.
How it makes money
A trip or call-out fee plus labor and parts for repairs, a fixed price per scale for calibration, and annual service contracts for businesses that need regular checks.
Skills that help
- Mechanical and basic electronic troubleshooting
- Careful, accurate measuring
- Record keeping and paperwork
- Customer service
Watch out for
- Many states require service companies or technicians who work on commercial (legal-for-trade) scales to be registered, check your state weights and measures office
- Test weights must be traceable and recertified regularly, so budget for that ongoing cost
- General liability insurance, and commercial auto cover for your vehicle
- Some customers, such as labs, may require accredited calibration, which is a separate and costly step, so check what your target clients need
- Check city or county business license rules and sales tax on parts
