Build a procurement agent that coordinates with vendors

e2a helps developers build procurement agents that receive vendor email, connect messages to purchase-order context, send follow-ups, and require human approval before sensitive commitments leave the organization.

THE WORKFLOW

What the agent does

  1. 01A vendor sends a quote, shipping update, invoice, or question.
  2. 02e2a delivers the message with sender-authentication evidence.
  3. 03The agent matches it to a purchase order or vendor record.
  4. 04It extracts the update and requests missing information when needed.
  5. 05Pricing, purchase, and contractual commitments wait for human approval.
  6. 06The agent follows up with the vendor and updates the procurement system.

WHY E2A

  • ✓Dedicated inboxes for procurement or vendor workflows
  • ✓Inbound authentication evidence and signed webhooks
  • ✓Threaded vendor replies and conversation correlation
  • ✓MCP, SDK, webhook, WebSocket, or REST integration
  • ✓Approval controls for commitments and unfamiliar recipients

START BUILDING

The integration stays small

E-commerce and vendor workflow ↗
event = await client.inbound.next("[email protected]")
po = await procurement.lookup_purchase_order(
    event.data["text"]
)
reply = await procurement_agent.follow_up(
    message=event.data["text"],
    purchase_order=po,
)
await client.messages.reply(
    event.data["delivered_to"],
    event.data["message_id"],
    {"text": reply},
)

The agent owns the business logic. e2a handles the email identity, delivery, authentication evidence, and reply routing.

FAQ

What can a procurement agent do with email?

A procurement agent can request quotes, extract vendor updates, chase purchase orders, ask for missing information, and keep supplier conversations connected to the procurement system.

Can a procurement agent read purchase-order context?

Yes. The agent can connect inbound email to the purchase-order, vendor-management, and inventory systems that contain the organization's business context.

Can humans approve vendor commitments?

Yes. e2a can hold messages for human review before sending pricing, contractual, purchasing, or other sensitive commitments.

Can procurement agents work with vendors that do not use e2a?

Yes. e2a sends and receives ordinary email over SMTP, so vendors can use Gmail, Outlook, or any other normal mail client.
