In 2012, Amazon.com entered the B2B wholesale marketplace with the launch of AmazonSupply. By 2014, Forbes reported that AmazonSupply was already offering 2.2 million products for sale in 17 categories, from tools and home improvement to janitorial supplies.

The quick growth worried industry experts. There was concern over whether America’s 35,000 distribution companies — almost all of which are regional and family-run — could compete with AmazonSupply’s infrastructure and deep cache of consumer data.

Now Amazon is taking its quest to win over the $7.2 trillion B2B sector a step further. On Tuesday, the Seattle-based web giant is launching Amazon Business, a new platform aiming to do for business customers what Amazon.com has done for everyday shoppers.

Forbes reports that on May 13, AmazonSupply will be subsumed into Amazon Business. At that time, companies that register for an Amazon Business account will have access to business-only products from IT and lab equipment to education and food service supplies, with bulk discounts and free 2-day shipping on orders over $49.

B2B account holders, who’ll be approved to shop based on their tax ID, will be able to compare product prices from multiple sellers on one page, just like they do when they browse Amazon.com from home.

Customers will be able to chat with experts based on-site at a manufacturer. Companies can also set up multi-user accounts, create approval workflows and integrate procurement systems.
