The short answer
Business Prime is bought from inside an existing Amazon Business account — there is no separate signup. Amazon bills annually, so the tier you pick commits a year. Run the four checks below before you buy, because most of what people upgrade for is already free.
| Plan | Price | Users | Best for |
|---|---|---|---|
| Duo | Free with a personal Amazon Prime membership | 1 user (sole proprietor) | A sole proprietor who already pays for personal Prime |
| Essentials | $179/year | Up to 5 users | A small office or team of two to five people |
| Small | $499/year | Up to 20 users | A growing team that has outgrown five seats |
| Medium | $1,299/year | Up to 200 users | A multi-department organization buying at scale |
| Enterprise | $10,099/year | Unlimited users | A large organization with formal procurement controls |

The six steps
- Confirm you need a paid tier at all. Business pricing, quantity discounts, multi-user access, approval workflows, purchasing reports and tax exemption are already free on the Amazon Business account. Business Prime adds free business delivery, Spend Visibility, Guided Buying, extended payment terms on higher tiers, and Prime Business Rewards. If what you want is on the free list, stop here.
- Check whether Duo applies to you. If you are a sole proprietor with a personal Amazon Prime membership, Amazon makes the Duo tier free. There is no argument against a free tier — take it and skip the rest of this decision.
- Count your buyers, then count them for next year. The seat caps are 5, 20 and 200 across Essentials, Small and Medium, and they are cliffs rather than a sliding scale. Because billing is annual, size the tier for where your headcount will be at renewal, not where it is today.
- Add up last year's Amazon shipping. Free business delivery is the main reason to buy. Open your order history for the last twelve months and total the delivery charges actually paid. If that number is near zero because your orders already qualify for free delivery, the case for upgrading has largely evaporated.
- Check whether you qualify for a trial. Amazon's plan page says 'see if you qualify for a 30-day free trial' on Essentials and 'an extended free trial' on Small and Medium. The wording is conditional and eligibility is Amazon's decision. If you do qualify, a trial answers the shipping question with real data instead of an estimate.
- Buy the tier from within your Business account. Business Prime is purchased from inside an existing Amazon Business account, not as a separate signup. Select the tier that matches your seat count and confirm. Amazon bills annually.
Step one deserves more space than it got
The most expensive mistake in this whole process is upgrading for a feature the free account already has. It happens constantly, and it happens because a lot of published guides list free-tier features under Business Prime.
Already free: business-only pricing, quantity discounts, multiple users with per-user permissions, approval workflows, purchasing reports, and tax-exempt purchasing.
What upgrading actually adds: free business delivery on eligible orders, Spend Visibility, Guided Buying, extended payment terms (45-day on Small, 60-day on Enterprise, both with a Business Credit Account upon approval), and Prime Business Rewards.
If none of those five is what you came for, close the tab and keep your $179/year. The full row-by-row is on Amazon Business vs Business Prime.
The seat-cap trap
The caps are cliffs. Crossing one forces the entire next tier, so a single hire at the wrong moment is expensive:
- User #6 — Essentials → Small: +$320 a year
- User #21 — Small → Medium: +$800 a year
- User #201 — Medium → Enterprise: +$8,800 a year
A five-person office fits Essentials exactly, with zero headroom. If a sixth hire is coming inside the year, you are choosing between buying Essentials now and re-buying at Small later, or sizing up from the start. Either is defensible; discovering it at renewal is not. Worked through on Essentials for a five-person office and offices and small teams.
The one case where you should skip a tier
If extended payment terms are a genuine cash-flow need, go straight to Small. There is no way to add 45-day terms to Essentials — buying Essentials first and upgrading later means paying twice for the same year. Note both of Amazon's qualifiers though: terms require a Business Credit Account and are granted upon approval, so the benefit is not guaranteed by the purchase. See Pay by Invoice and net terms before committing $499/year on that basis alone.
Use a trial if Amazon offers you one
The hardest input in this decision is what you currently pay for shipping, because Amazon publishes no per-order figure and it varies by order. A trial replaces that estimate with your own data.
Amazon's wording is conditional — "see if you qualify" — and we will not restate it as a guarantee. If you are offered one, buy exactly as you normally would during the window rather than placing orders you would not otherwise place, then annualize the delivery charges you did not pay and compare.

Know the exit first
Read how to cancel Business Prime before upgrading, not after. It takes two minutes and it covers the thing people most often get wrong: canceling the membership is not the same as closing the account. Drop Business Prime and the free tier underneath keeps business pricing, multi-user access, approvals, reporting and tax exemption.
