Each rooftop records the brands and categories it carries, and the Sales Agent answers from that. A buyer asking about a brand you do not sell gets a straight answer and a route to what you do sell.
A buyer almost never opens with a model number. They open with a brand, or a category, or a use case.
Until now the agent answered those questions in general terms. It now answers them from what the rooftop in front of the buyer actually carries.
What each rooftop sells is now something you record
Every rooftop holds its own list of the brands and categories it sells and services. A group with different franchises at different stores describes each one once, and each store's agent answers accordingly.
A straight answer beats a hopeful one
Asked about a brand a store does not carry, the agent says so and points the buyer at the closest thing it does carry. That is a better conversation than an enthusiastic non-answer, and it is a far better one than a buyer arriving to find the thing they asked about was never on the floor.
