What it is

A trade-focused parts supplier. You list common garage door parts and accessories online, take orders from installers and builders, and ship from a wholesale distributor or from a small stock kept at home.

Your first three steps

  1. Contact a few garage door manufacturers and wholesale distributors to ask about trade accounts, minimum orders and drop-ship terms
  2. Get a resale certificate or seller's permit if your state requires one, and set up a simple online store with a trade price list
  3. Visit local installers and builders with a short parts catalog and offer a first-order discount or free local delivery
Who pays

Independent garage door installers, handymen, builders, property managers and remodeling contractors who need parts fast.

How it makes money

You buy at wholesale or trade prices and sell at a markup, with extra margin on bundles, same-day local delivery and repeat trade accounts.

Skills that help
  • Knowing garage door parts and how they fit
  • Order handling and organizing stock
  • Building relationships with trade customers
Watch out for
  • Check your state's rules on sales tax registration and resale certificates
  • Product liability and general liability insurance, especially for springs and openers that can cause injury if installed wrongly
  • Consider selling high-tension parts to trade customers only, and check what your suppliers allow
  • Home business rules: check your city or county, HOA or lease before storing stock at home
  • Returns and wrong-part orders can eat margin, so confirm part numbers and sizes before shipping
