A buyer messages at 8 PM saying they want the white Camry but can't come in until Saturday, and asks if the dealership can hold it.
Without a deposit, holding the car means turning away other buyers on a handshake. Asking the customer to drive in just to pay a hold fee usually ends the conversation.
The rep creates a deposit payment link with the hold amount directly from the chat and sends it in the same thread. The customer pays on the secure hosted page from their couch.
The Paid status appears in the conversation, the car is marked held with real money behind it, and the buyer shows up Saturday to a vehicle that waited for them.
