Top line revenue is the total amount of revenue that your company generates from its customers.
Top line revenue is calculated by adding up all of the revenue that you have generated from your customers over a certain time period.
For example, if you had a total of $1,000,000 in revenue during the month of January, your top line revenue for January would be $1,000,000.
Top line revenue is a very important metric because it is the total amount of revenue that your company has generated from its customers. It is the first step in determining your company's revenue growth.
Top line revenue is also important because it is a good indicator of how much money your company has to work with in terms of new product development, marketing, and other expenses.
