Gross Revenue is:
number of units sold * sales order price before discounts
Gross Revenue does not subtract returns and is same as Gross Sales metric in Shopify.
gross revenue - discounts - returns
Returns use the sales order return date, not original order date. This is the same as Net Sales metric in Shopify
Total Revenue is:
Gross Revenue - Discounts - Returns + Taxes + Shipping
Total revenue will be a positive number for a sale on the date that an order was placed, and a negative number for a return on the date that an order was returned. This is the same as Total Sales metric in Shopify.
