There are only three ways to increase sales revenue. More clients, more spent per client, more frequency of the client buying. The power is in multiplying them.
Let's start with a baseline: you have 100 clients spending $100 each time they buy and they buy once per month. That gives us $10,000 per month.
If you increase any one of these by 30%:
30 more clients
$30 more spent each time
30% increase in buying frequency
You will see a 30% increase in revenue - $13,000. That's nice, right?
Here's where it helps to have paid attention in math class:
Increase any two and you don't get 60% increase, you get 69%.
Increase all three and you get 120% increase.
That takes you from $10,000 to $16,900 or $21,970 respectively - double your revenue.
It may take you a month to increase all three, it may take you a year. As fast as you can grow these, your company will grow exponentially.
Fun with figures.
