The retail pipeline problem is capture, and everything else is downstream
In most considered-purchase retail businesses, the majority of people who walk in leave without buying and without leaving a trace. The store knows its sales figure and has no idea of its conversion figure, because the denominator was never recorded. Every subsequent question, whether the second outlet is underperforming, whether the new display worked, whether a particular staff member converts better, is unanswerable for the same reason.
So the first and hardest piece of the routine is not follow-up automation. It is getting four fields recorded for a person standing in front of you who did not come in expecting to give their number. Everything below assumes that problem is solved first, because a store with excellent quotation follow-up and poor capture is carefully working a small and unrepresentative slice of its own traffic.
