The short answer
An administrator invites you — by email, by shared invite link, or from a spreadsheet. You accept and create your own username and password, and Amazon associates that user account with the organization's. Amazon also states that if your organization already uses Amazon Business, you may see an option to request joining during registration.
There is no self-service way onto somebody else's Amazon Business account, and that is deliberate. The account carries the company's payment methods, addresses, tax exemptions and purchasing policies. Access is granted, not claimed.
Which makes the useful version of this page short on mechanics and long on the two decisions that are yours: which email address you join with, and what you agree to hand over by joining.
The routes an administrator has
Amazon publishes three, and they differ mainly in scale:
- By email. The administrator enters addresses, selects roles, and sends the invitation. This is the normal route for one person joining.
- By invite link. The same invitation, shared through a message rather than addressed individually.
- By spreadsheet. Amazon states administrators can use a spreadsheet to add up to 1,000 people to a business account, change roles, and add or remove people from groups. This is the onboarding-day route.
If you have been waiting on an invitation, Amazon sends a reminder email after 3 days without a response — so silence beyond that usually means the invitation went to an address you are not watching, or never got sent at all. The administrator's side of this is on adding users to Amazon Business.
The email address decision
This is the whole page, really. Amazon's guidance is explicit: use a business email address that is not already associated with an individual Amazon account, because doing so ensures individual and business order histories remain separate.
The alternative — joining on the address you already use for personal Amazon shopping, or converting that account outright — has a consequence Amazon states directly: your personal information becomes visible to administrators in the business account. Not future purchases only. Converting a personal Amazon account goes through exactly what that exposes.
There is also a hard constraint underneath: an email address can be associated with only one business account at a time. If yours is still attached to a previous employer's account, a new invitation to it will not work, and that is the first thing to check when an invitation appears to vanish. See logging in to Amazon Business for the rest of that diagnosis.
What the administrator can see
Amazon does not hedge on this, and neither will we. On its own description of business accounts, Amazon states that administrators can see members' account information — including order history, addresses, payment methods and personal information — and can manage or close business user accounts.
That is the correct design for a company purchasing account. It is also the reason the address you join with matters more than any other setting on this page. Join on a work address and what your employer can see is your work buying. Join on your personal one and the boundary is gone.
The policy side is worth reading once too: Amazon's acceptable use rules do not permit personal buying on a business account, whatever the visibility question. That is covered on personal use rules.
The role you get, and why things are missing
The administrator picks your role as part of the invitation, and it can be edited later in Business Settings. Amazon lists five:
- Administrator. Manages the business account: invites users, and manages shared payment methods, shipping addresses and delivery preferences.
- Buyer (Requisitioner). Places orders for the organization, after an administrator assigns the permissions.
- Punchout user. Places orders through a purchasing system rather than the Amazon Business storefront.
- Finance user. Accesses, customizes and schedules Amazon Business reports.
- Tech user. Manages domain names, authentication methods, API keys and IT system integrations including single sign-on.
A person can hold more than one. Most new joiners are buyers, which is why the first surprise is usually a missing report or an invoice you cannot download — those sit with the finance role. Ask for the role rather than for support; changing the account administrator covers who is allowed to grant what.
Groups, approvals and why your order stopped
Organizations of any size put people into groups, and a group carries its own payment methods, shipping addresses and — often — an approval requirement. So the second common surprise is an order that does not place itself but goes to somebody for sign-off.
That is your employer's policy working, not a fault. Multi-user accounts and approvals explains the mechanism, and shared payment methods explains why the company card appears at checkout for some people and not others.
What joining does not cost you
Nothing. The Amazon Business account itself is free, so being added is free. If your organization holds a Business Prime membership, your seat counts against its user allowance — which is the organization's cost, not yours, and the reason a growing team sometimes has to wait for a plan change before the next person can be added. Business Prime plans compared has the seat ceilings.
