What is Amazon wholesale sourcing?

Buying in bulk from brands and distributors at trade prices to resell on Amazon.

Wholesale sourcing means opening accounts with brands and authorised distributors, buying their products in bulk at trade prices, and reselling on existing Amazon listings. Compared with arbitrage it trades higher entry effort - supplier relationships, minimum orders, invoices - for repeatable supply: the same profitable product, reordered monthly.

The daily grind of wholesale is the price list: suppliers send spreadsheets with thousands of lines, and each line has to be matched to Amazon and priced after fees. That matching is the part software does in minutes - upload the list, get profit per line, sort by what is worth stocking.
