The first step is getting to know your customer, and that comes from data. So I would start with mining the data, putting together relevant offers, and test them repeatedly. This is not something that can be done very easily with manual processes, throwing around Excel spreadsheets and trying to get HQ to communicate out to the field. Build a tech stack to first dig into the data and help you get to know your customers. The right tech stack will also help so you’re not manually trying to administer personal promotions.
