The short answer
Sole proprietorships are explicitly eligible — Amazon names them in its account terms. The account is free, and Duo costs nothing extra if you already hold personal Prime and the account has one user. The real trade-off: you cannot use the business account for personal shopping, so you will run two.
This is the segment where the decision is genuinely close, and where most guides are least useful — they describe features designed for organizations of fifty people and leave a freelancer wondering what any of it has to do with them.
So: three things that actually apply to a one-person business, and one reason to walk away.
1. You are eligible, whatever you were told
The account terms define Eligible Entities to include all types of businesses (for example, LLCs, LLPs, corporations, partnerships, sole proprietorships, and PLLCs).
Sole proprietorships, by name. There is no registered-company requirement, no revenue floor, and no employee minimum. The persistent belief that you "need a real business" comes from people reading Amazon Seller requirements, which is a different product entirely — see Amazon Business versus a Seller account.
On the tax ID field, Amazon asks for a tax identification number rather than specifically an EIN. If you have one, use it. If you do not, that is a decision about how much you want to hand your SSN to vendors generally, not an Amazon-specific hurdle. Detail on sole proprietorship or LLC.
2. Duo is the cheapest membership on the platform, conditionally
Duo is built for exactly this reader. Amazon states it is free for business accounts with one user, where the account uses the same email as your personal account or you link a personal account holding an Amazon Prime membership.
Two honest qualifications:
- "Free" means no incremental cost. If you were buying personal Prime anyway, Duo is a free upgrade. If you would be buying personal Prime in order to get Duo, price it as what it is — a personal subscription with a business feature attached.
- It ends the moment you are not a one-person business. Amazon states adding more users makes the account ineligible for Duo at the time of renewal.
Duo carries the full Prime Business delivery set and 2% Prime Business Rewards, but Amazon states it does not include Spend Visibility or Guided Buying — which for a one-person business is no loss at all. All eight published Duo conditions are on Business Prime Duo explained.
3. The features that survive at n = 1
Most of the Amazon Business feature set assumes an organization. Here is what is left when the organization is one person:
- Business-only pricing and quantity discounts. Amazon says quantity discounts start from as low as two units — which is exactly the scale a freelancer buys at.
- Clean separation for bookkeeping. One account, one payment method, one export. At tax time this is the feature you will actually thank yourself for.
- Business Analytics reporting, free, exportable as CSV — see QuickBooks and accounting integration.
- Tax exemption, if you hold a certificate — a resale certificate is common for freelancers who buy materials that go into client work.
- Subscribe & Save at 5% on eligible products, with a tiered uplift at five subscriptions arriving the same day to the same address. A home-office freelancer can reach five without stretching.
What does not apply: approval workflows with nobody to approve, Guided Buying with nobody to guide, Spend Visibility dashboards with one department, punchout with no procurement system, and shared addresses with one address.
The reason to walk away
Amazon's Acceptable Use Policy states you must use Amazon Business exclusively for business purposes, and may not purchase products through it for personal or household use.
For a company with staff, that rule is invisible — people already have their own accounts. For a one-person business it is the whole decision. Today you probably buy printer paper and a birthday present in the same basket. That has to stop: two accounts, two email addresses, two payment methods, permanently.
If you buy from Amazon three times a year and hold no exemption certificate, that friction is not worth a few percent on stationery. Say no, and spend the hour on something else. The full picture is on personal use rules and the drawbacks.
Do not convert your existing account
The signup flow makes converting your current Amazon login look like the easy path. It is the one decision on this page that is hard to undo.
Amazon's Acceptable Use Policy states that where a personal consumer account has been converted to a User Account, the people who control the Business Account have access to all personal information on that account before it was converted. For a solo business you are that person, so the privacy risk is nil today — but it becomes real the moment you take on a partner, sell the business, or bring in a bookkeeper as an administrator.
There is a second, more immediate reason: Amazon states that if you use the same credentials for your personal and business account, you must have Prime on the personal account, and accounts set up that way cannot link a different Prime account later. Start clean. See converting a personal account.
When you outgrow this page
The transition is sharper than for any other segment, because Duo has a hard one-user rule. The day you add a second person:
- Duo ends at the next renewal.
- Essentials at $179/year covers up to 5 users.
- Amazon's terms state your fee increases automatically if your user count moves you into a higher plan.
