What it is

A small online shop selling electronic components such as resistors, capacitors, connectors, sensors and development boards. You can start with a narrow range, such as parts for Arduino or Raspberry Pi projects, and stock it from wholesale suppliers and distributors.

Your first three steps

  1. Pick a narrow niche, such as hobby kits or repair parts, and compare prices from a few UK and overseas wholesalers
  2. Order a small trial stock and list it on your own simple shop and one marketplace
  3. Set up clear labelling, packaging and a postage price list, then ask early buyers for reviews
Who pays

Hobbyists, students, makers, repairers and small workshops who want small quantities quickly without trade accounts.

How it makes money

You buy in bulk and sell in smaller packs or kits at a mark-up. Profit comes from the gap between buying and selling price, minus postage and marketplace fees. Bundles and project kits can raise the order value.
