What it is

A small supply business run from home. You quote and sell listed sprinkler heads, pipe fittings, valves and suppression parts to installers and contractors. Most orders ship direct from the manufacturer or a larger distributor, or come from a small stock of fast-moving items.

Your first three steps

  1. Learn the product basics through manufacturer training and by talking to local installers about what parts they struggle to get quickly
  2. Apply for dealer or reseller accounts with a few manufacturers and distributors, and register for a resale certificate with your state
  3. Form an LLC, get an EIN, and visit five local installers with a short price list and a promise of fast quotes
Who pays

Fire sprinkler installers, mechanical and building contractors, facility maintenance teams and fire protection service companies.

How it makes money

You earn the margin between your wholesale price and your selling price on each order. Repeat accounts with installers who reorder parts for ongoing jobs are the core of the business.

Skills that help
  • Reading parts lists and spec sheets
  • Sales and relationship building with contractors
  • Careful order and invoice tracking
Watch out for
  • Check that every product you sell is listed or approved for its use (for example UL or FM), since installers and inspectors will ask
  • General liability and product liability insurance, as a wrong or faulty part can be costly
  • Some states and cities license fire protection contractors; check whether your plans (such as extinguisher sales or service) trigger a license
  • Thin margins and manufacturers' minimum order or dealer requirements
  • Sales tax resale certificates and home occupation or HOA rules
