Reverse Sourcing on B2B Supplier Hub: One Product, Start to Finish

Somewhere in your catalog right now, there is a product doing well through exactly one supplier. You know the one. It sells steadily, the margin works, and every reorder quietly depends on a single company staying stocked, keeping its price reasonable, and staying in business.

Finding a second source for that product is the job this post walks through, on a real product and screen by screen. The workflow is called reverse sourcing, which means working backward from a product to the suppliers who carry it. If the concept is new to you, the 5-step reverse sourcing workflow explains it properly. This post is where we actually do it: one processor, one session on B2B Supplier Hub, and a supplier shortlist a few minutes after the first search.

Start From a Proven Product (Our Example: an Intel Core i7 Processor) 

Our example is an Intel Core i7-14700 processor. A recognizable product with steady demand, the kind of item a reseller might already be selling through one source and quietly worrying about, because processors are exactly the category where a single supplier's stockout or price move hurts. If you're still building your first list of sources, start with our guide to finding wholesale suppliers for Amazon FBA — this walkthrough assumes you already have a product that sells.

The starting point is the identifier. From your own listing, a marketplace page, or the box itself, you take the UPC, the MPN, or simply the product name, and you search it. If you're already looking at the product on Amazon, the Chrome extension brings the same answer to you right on that page, but for this walkthrough we'll stay on the platform.

Check the Supplier Count Before Anything Else 

The product page opens with the picture that matters before any detail does: how many suppliers in our network carry this exact product, and what the average stock situation looks like.
