If it's customer pay, require prepayment on s/o parts if the vehicle is not staying in the shop, PERIOD
Internal? pre-bill all internal on an RO or parts invoice.
Warranty-no choice here. You have to order. It is the service advisor's responsibility to connect with the customer and get them back in. If I were an advisor, I guarantee you I'd do all I could to get them back in. After all, it's my money too. In too many dealerships you see departments passing the buck on this issue. Service says its parts' job, parts says it's services' job. Stop the BS. Be accountable. If you are an advisor, you need to be the one on the front line for the customer's sake and the stores'.
Forget mailing cards, that's so 80's. I've read recently where texting is the preferred mode of contact for a customer. Makes sense. Everybody is walking around with their heads down staring at the screen anyways.
