The presenter shows a scenario with two shipping-enabled locations where, without Switchboard, shipping rates come from multiple fulfillment locations. They then go to Functions, add a fulfillment constraint labeled to prevent split shipments, and activate it so that entering a new zip code blocks fulfillment splitting. The discussion also notes optional front-end messaging and that checkout value validation functions have no inventory notice, while Switchboard supports other routing use cases like country and per-product fulfillment.
