Coupa is a business spend management suite used by larger organizations to manage procurement, suppliers, invoices and spend. Atta covers less ground and does the last step too: an agent that takes a request in chat, runs the approval rules, pays with a capped single-use card and tracks the order to its invoice.

## What Coupa does well

Coupa belongs to the business spend management suite category: procurement, supplier management, invoicing and spend analysis in one platform, built for organizations with many suppliers, entities and approval layers. If your company needs that breadth and a team to run it, a suite is built for it.

## 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 | Coupa |
| --- | --- | --- |
| Scope | Everyday and tail purchases, inventory, cards | Company-wide spend management |
| Request | Chat message or form | Requisition in the suite |
| Approval | Chain from amount and rules, checked in code | Configurable approval workflows |
| Order | Agent places it | Purchase order sent to the supplier |
| Invoices | Linked to the PO they name | Invoice processing is part of the suite |

## One order

Here's one request in Atta. Maya asks for a replacement badge printer at $780. The rules route it to her manager. After approval, the agent orders and pays with a card capped at $780, and the invoice links by its PO number. That covers the whole path for one small purchase, with nothing around it like supplier contracts or sourcing events.

## When to pick Coupa instead

Coupa is the better fit when:

- You have many entities, contracts and suppliers, and procurement is a function with its own team.
- You need supplier management, sourcing events and spend analysis across the company.
- Compliance and auditing requirements call for a platform with that depth of configuration.

## 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

### Is Atta an alternative to Coupa?

For the purchases that never reach a procurement team, yes. It doesn't replace a suite for supplier management, sourcing events or company-wide spend analysis.

### Can Atta sit next to a suite?

Yes. Use it for tail spend and let the suite handle contracted spend.

### Does Atta handle invoices?

It links received e-invoices to the purchase order they name and stores the payload as it travelled. See the e-invoicing page.
