In order to understand how to get where you are going, first you must set the destination. Mission Control will perform calculations on how to accomplish the set Objective based on the expenses and financial organization within your company.
If you don't know where to start, start at 0% for breakeven. You can always gradually increase from there to see the necessary outputs of your goal.
The Mission Control system will guide you on parameters that make sense for your business. For example, you might come across these error messages:
If your goal is too low
If your goal is too high
Mission Control will tell you what you need to do to accomplish this net margin goal like, reducing fixed expenses, or increasing prices, or increasing conversion rate, or increasing ad spend.
