Hi! Im trying to improve my current loyalty program, I basically classify my customers manually each month, depending on their sales. Im looking for a tool where I just attach my excel sales numbers, providing insights and possible tiers. Thirdshelf is kind of what im looking for, however I can't use it because this data is in excel. However, when I analyze my 2025 I find myself doubting if what I've been doing is good enough, plus my system has some limitations such as not being able to identify missing customers, which means Maybe a customer didn't come back this month, which doesn't affect its status. My main goal is to reward my customer's total sales and frequency, however I've found that differences between some customers are minimal making segmentation a PITA, I can't decide where to make the cut.
