What it is

An online shop focused on one hardware niche, such as period-style door and gate hardware, cast iron brackets, or fittings for restoration projects. You can hold a small stock at home or use suppliers who ship for you.

Your first three steps

  1. Choose a narrow niche and compare supplier prices and minimum orders for 20 to 30 products
  2. Set up a simple online store and photograph or collect approved images of your first products
  3. Order a small first batch, ship a few test orders to friends, then list on your store and a marketplace such as Etsy or eBay
Who pays

Homeowners doing renovations, restorers, small builders, designers and woodworkers who can't find the right piece locally.

How it makes money

You earn the margin between wholesale and retail price on each item. Bundles, matching sets and shipping-inclusive pricing can lift the average order.
