Conceptually, the biggest difference between the Sales and Finance Reports in your dashboard is this:

• Sales Reports highlight the value of all products and/or services sold during a specific time period, regardless of how much money was actually collected at the time of sale.
• Finance Reports highlight the actual transactions or exchanges of money that took place during the time period selected, whether in the form of a payment or refund.

The video below provides a more detailed walkthrough of each report.
