The ArbiSource FBA Handbook (UK)

Welcome. This handbook is for anyone who wants to buy products from UK retailers and resell them on Amazon.co.uk using Fulfilment by Amazon (FBA), and who wants to use ArbiSource to find those products faster.

You don't need any experience. We start at the very beginning (what FBA is, what a seller account is, how the money flows) and build up, one step at a time, to finding, checking and buying your first products.

Who this handbook is for​

  • Complete beginners who are curious about online arbitrage and want an honest, practical picture before spending money.
  • New ArbiSource users who have just started their 7-day free trial and want to get set up properly on day one.
  • Existing Amazon sellers who are new to sourcing tools and want a clear method for checking deals.

This is the UK edition. Everything in it (prices, tax, fees, box rules and retailer examples) is written for selling on Amazon.co.uk. If you sell on Amazon.com, use the US edition of the handbook instead. The two marketplaces work quite differently.

🧭 Choose your path

You can mix these. Many people follow the Quick Start on day one and then come back to the chapters as questions come up. Each chapter explains the why as well as the how, with videos, screenshots and checklists.

The in-app welcome guide​

When you join ArbiSource, you're taken to its in-app welcome guide: a tour of every feature with short video guides. You can go back to it at any time once you've signed up, at app.arbisource.com/welcome. This handbook goes alongside it, adding the Amazon knowledge and the step-by-step method for deciding what to buy.
