I have a Business account, but without Prime. Yes, I save on certain supplies, but unless a lot is being bought, it doesn't add up to much. I mostly have it to keep my work orders separate from my personal orders. No one has bothered to call me about anything, and it's just like having a regular account. You would have to get Prime for the business account as well or have the company owner see if they can switch it from one account to another. It may be a good idea to wait until close to renewal for the owner to cancel on the old account and switch Prime to the business account. More on reddit.com

Amazon business is nice if you want a lot of people to have access to the account, but one person who can view/approve all of the purchases. I've never actually seen/used one of the exclusive deals, I've purchased like 20 computer mice but it wasn't enough for a bulk discount. In my experience it's in no way superior to prime, aside a purchasing person having access to multiple linked accounts/being able to approve purchases. It is free 2 day shipping with no subscription cost, though. More on reddit.com

It can be a little difficult to keep your personal orders and business orders separate, especially when searching for old orders that you don't remember under which umbrella you chose to place the order. The list of Departments is re-arranged in such a way that if you often purchase non-business related items like clothing or consumer-electronics, you now have to dig deep to find those. An extra step in the check-out process for PO Number (it's not required but does take up the whole screen and is one additional required click-through). It takes a little bit of setting up to get payment options and approval requirements all dialed in for account users and groups (even if you're the only one using the account, you will still have to manage your permissions etc the same as if you were 1 of 100 with access). It takes a while to get used to all of the new places to find account information and moving back and forth between managing yourself as a user from the business side and then actually doing stuff from within your user's. All of the cons are minor but kind of annoying/complicated when you're used to logging in as a single user. The pros are multi-user and group access, shared-payment/order approval settings, custom reporting, dedicated customer service tier and maybe the line of credit? More on reddit.com

I guess the point of it is so that you don't have to separate out your business expenses from your personal expenses on there? More on reddit.com
