Amazon Business is a marketplace where businesses buy from one catalog with business accounts. Atta is an agent that works across the stores you allow, gets approvals before it spends, pays with a capped single-use card, and keeps the budget, the order and the invoice on one request.

## What Amazon Business does well

Amazon Business is a marketplace: one catalog, one checkout and delivery network for business purchases. For a team buying common supplies and equipment, a single place to search and buy is simple, and the catalog is broad.

## Where Atta differs

Atta follows a purchase from the first message to the invoice. The sequence:

- Someone asks in Slack, WhatsApp, ChatGPT, Claude or the browser.
- The agent searches the stores the workspace allows and shows the item, price and delivery date.
- A policy function decides `auto`, `ask` or `deny` from the amount, the person's role, the budget left and the workspace's rules. Code makes that call, not the model.
- Over a limit, an approval chain is built and answered one approver at a time. The approval binds to the amount and the lines, and a changed cart fails the order with both figures.
- With a card program on, the agent pays with a single-use virtual card for that order, capped at the approved total on the issuer's side too. Without one, it hands over the checkout link.
- Checkout reserves the budget and payment settles it. A received invoice links to the PO it names.

The agent places the order. If placing it fails after approval, it waits for a person to press Try again, and a spend is never retried automatically.

## Side by side

| | Atta | Amazon Business |
| --- | --- | --- |
| Where it shops | Stores you allow: a connected Shopify store, UCP stores, the open web read-only | One marketplace's catalog |
| Who searches | The agent | The buyer |
| Approval | Chain from amount and rules, enforced in code before payment | Account-level approvals |
| Payment | Single-use card per order, capped at the approved total | Checkout in the marketplace |
| Budgets | Reserved at checkout, spent when payment settles | Per your account setup |

## One order

Here's one request in Atta. Jo asks for 20 USB-C cables. The agent searches the stores the workspace allows, shows the best price among them, say $9 each for $180, and Jo confirms. Atta only shops at stores you have configured, so a marketplace you haven't added isn't searched. Where a store isn't buyable from here, the agent gives you the link to open yourself.

## When to pick Amazon Business instead

Amazon Business is the better fit when:

- Most of what you buy is in one marketplace's catalog and one checkout is fine.
- You want to buy supplies yourself without an agent or request step.
- Your approvals are light and handled inside the marketplace account.

## Using both

Atta covers the purchases someone can ask for in a sentence. Other spend can stay where it is. Atta is in invite-only beta and free during the beta.

## Questions

### Can Atta buy from Amazon Business?

Atta shops at stores you configure: a connected Shopify store, stores that support the Universal Commerce Protocol, and the open web read-only, where it hands you the link to buy.

### Why use an agent over a marketplace?

The agent compares across the stores you allow and the approval policy runs in code before any money moves. A marketplace gives you one catalog.

### Does Atta suggest stores I haven't set up?

No. It only suggests the stores and brands your preferences allow, and a 'never' is a filter on the results.
