Suppose you allocate to your customers 3 of Activity A/month and 5 of Activity B/month. How do you keep track of what you've allocated and what they've used every month?
Something that is going to show me this on the first of the month:
Activity A Activity B Customer Lily 3 0 Customer Chuck 3 5 Customer Francis 3 5
and this in the middle of the month, etc:
Activity A Activity B Customer Lily 3 5 Customer Chuck 1 4 Customer Francis 1 2
So I know what they've used and how many are remaining.
What is the terminology used to describe this "activity tracking"? What best-practices are recommended for doing this efficiently?
