This is an account management business, not a marketing one
Liquor retail and wholesale operate under conditions that rule out most of what a consumer-facing CRM is normally used for. There are no promotional broadcasts to drinkers, no discount campaigns pushed to a customer list, no loyalty messaging. What remains is the part that actually determines whether a licensed business grows: the outlets you supply, the volume they take, the credit you extend, the dates you must not miss, and the coverage your field team achieves.
That is a demanding operational job and it is almost always run on memory and spreadsheets. This page is about doing it properly.
