Buying custom packaging has always involved a long, manual discovery phase. You describe a box to a supplier, wait for a reply, ask what it costs at 500 units instead of 250, ask again about a different board, and repeat that across three or four vendors before you have anything comparable. Most of that work is retrieval, not judgment.
Agentic commerce moves the retrieval to software. You ask an assistant for rigid boxes at 500 units with a soft-touch finish, and the assistant queries suppliers directly, pulls back real prices and real minimums, and puts a comparison in front of you. The judgment stays with you. The fetching does not.
For that to work, a supplier has to publish machine-readable answers. A PDF line card and a contact form are invisible to an agent. Teal publishes the catalog, the prices, the minimums, and the quote path as endpoints an agent can call, which is why an agent can answer a question about Teal without guessing.
