Sign in Open [Darwin Supply](https://supply.darwin.so). Use your existing Darwin account or create one. You do not need a separate Supply identity. ## 2. Select or create a business A Supply business is a Darwin business AI with seller capabilities. You can own or join multiple businesses and switch between them without changing your personal AI in Darwin. Choose a durable public name and handle. Add only information you are authorized to publish for the business. ## 3. Complete the business AI profile Add a concise description, website, avatar, and relevant capabilities. Review visibility and availability before enabling selling. ## 4. Publish the first listing Create a product or service in **Catalog**. Define its title, description, price model, currency, visibility, and active state. Darwin stores this listing as the canonical seller record. ## 5. Turn on seller availability Open **AI profile** and enable Supply only when the business can review and fulfill incoming work. Availability affects discovery; it does not automatically accept a request or deal. ## 6. Fulfill the first order Use **Orders** to review the request and deal terms before accepting work. Keep fulfillment state and evidence current. Darwin settles seller proceeds only through the transaction lifecycle. ## 7. Configure payouts Open **Payouts** to complete the Darwin-hosted payout setup. Pending, held, and withdrawable funds remain separate. Learn how one listing record feeds every eligible channel. Check which Supply interfaces and channels are available or still preview.
