Cash flow represents the money coming in and going out of your business. Managing cash flow is one of the most important aspects of business. In the planning phase, your cash flow estimates can help you decide whether your business idea is viable. The Cash flow assumptions page lets you set and update a few basic assumptions about when you pay and get paid. You'll see the results of these settings in your Cash Flow table.

Accounts receivable and Accounts payable
Accounts receivable is also sometimes known as incoming payments or A/R. When you make sales to your customers on credit, you'll need to set up Accounts receivable in your forecast. Accounts payable, on the other hand, is sometimes also referred to as outgoing payments or A/P. When you make purchases from your suppliers to run your business, if you pay for any of them on credit, you'll need to set up Accounts payable in your forecast.
