Estimates for a small start in Australia, not guarantees.

What it is

A small web shop focused on replacement cartridges and filters for popular fridge, jug, benchtop and under-sink brands, with clear fit guides.

Your first three steps

  1. Pick a niche, such as fridge filters or one or two brands, and check wholesale prices and minimum orders
  2. Register an ABN, then set up a simple online store with fit-checker guides and clear returns information
  3. Order a small first batch of stock, photograph it and test the shop with local social media groups and search ads
Who pays

Households and small offices that want to reorder the right cartridge without searching for it each time.

How it makes money

Margin on each product sold, plus repeat orders from subscriptions or reminder emails. Bundles and multi-packs can lift order value.
