These are the only ways to increase revenue, but which one is the most important and why?
An article that explains why the following is the best order of importance in detail:
1. A stream of clients – without a steady flow the next two are redundant.
2. Higher transaction size – better get more money now than “maybe” later.
3. Repeat clients – now get them to return and concentrate on number 2 again.
It would be nice if such a reverse connection exists.
