What it is
A web shop focused on one niche, such as period door and window furniture, cast iron fittings or gate and garden hardware. You can hold stock in a spare room or unit, or have suppliers send orders direct.
Your first three steps
- Pick a niche and shortlist suppliers who offer trade accounts or will dropship small orders
- Set up a simple online shop with accurate sizes, finishes and photos for around 50 products
- Test with a small stock of best sellers and list on a marketplace to learn what customers search for
Who pays
Home owners restoring or renovating, joiners, builders, landlords and interior designers who want items the high street does not stock.
How it makes money
Mark-up on each item sold. Clear photos, sizes and finish guides help justify the price and cut returns. Repeat trade customers can bring larger orders.
