The sales team a small seller never had

Seller Desk answers customers from your catalog, asks you only what it cannot know, and closes the sale with a PayPal payment the server has checked.

Spoke Street Cycles is a fictional shop. Payments run in the PayPal sandbox, so no real money moves.

One sale, start to finish

One sale, start to finish. An illustration of the flow you can try in the demo shop.

Try it in two minutes

  1. Ask the shop

    Ask for a gift under $100 or a brake cable repair. It answers from the catalog and asks the owner the rest.

  2. Pay in the PayPal sandbox

    Add disc brake pads and press Pay with PayPal. The server checks the payment before any order exists.

  3. See it on the owner's desk

    Sign in to the desk. The order is there with its next step, beside the customer waiting for a price.

Judging this entry?

The shop needs no login. The owner’s desk does: its email and password are in the testing instructions of the submission, with a PayPal sandbox buyer.

What is different

  • The model never decides money

    Prices, totals and payment status are server records checked against PayPal. Paying twice makes one order.

  • It learns only what you approve

    Each answer is split into a fact for every customer and a favour for one. Only approved facts are used again.

  • The owner can test it first

    Simulated customers talk to the real assistant in a throwaway copy of the shop. Every quote is checked.

Agentic commerce, with limits

Your own AI can work the desk

Paste one line into Claude Code, Codex or Cursor, or add the connector in ChatGPT or Claude. It reads who is waiting, orders and offers, and drafts answers.

It can never message customers, change prices or move money.

The owner's desk: orders with the next step each one needs

One desk for what is owed

Paid is not done. Every order shows its next step: confirm a time, hand over at pickup, finish the work. Questions the assistant could not answer wait in the same place.

A WordPress plugin or one script tag puts the assistant on the website a seller already has.

Open the shop and ask it something
