Who's your supplier?

In my cursory glance at the prime movers, I've yet to separate out the terms. When I go large I get app vendors and - circling back to where it begins, the manufacturer - auto suppliers. While I'm getting an education in the different types of distributor, what sets them apart from vendors and suppliers?

Vendors supply here. Now that we've found Wikipedia dozing in the corner and they came back with this

A vendor, or a supplier, is a supply chain management term that means anyone who provides goods or services to a company or individuals. 

So this means we've jumped the gun by mentioning vendors/suppliers as they include more than the wholesalers and manufacturers we've canvassed; indeed it is awfully broad. There are rooters and tooters and a pair of shooters. It was just that the official site explaining terms to fledgling Aus exporters and the like, spoke of the different types of distributors as sourcing from 'manufacturer/vendor' so I felt bound to introduce the term.

As you can deduce, if it is true that suppliers aren't always toppling the divide, it is the example they set that make it a reasonable proposition. The lot of the small supplier is less attractive.

Which is not to say you shouldn't deal with a smaller vendor.
