What it is

You spend time at a client's workshop or unit, seeing how things are made, timing jobs and tracing materials and waste. You then build costing models and regular reports that feed into pricing and purchasing decisions.

Your first three steps

  1. Choose one local industry, such as food production or engineering, and list ten firms nearby to approach
  2. Prepare a short sample costing report using a made-up product, to show what clients would receive
  3. Offer a discounted first study to one manufacturer in return for feedback and a written testimonial
Who pays

Small manufacturers, engineering shops, bakeries, furniture makers and print firms with several products and tight margins.

How it makes money

A project fee for the initial costing study, followed by a monthly retainer for updates, reports and pricing advice.
