Cometly's calculation for Net Profit is based on Gross Revenue minus Amount Spent. Cometly does not keep track of the Cost of Goods Sold (COGS) for the products that you are selling. However, Cometly's 'Gross Revenue' is based on the final revenue of your order, so any discounts applied will be included on Cometly's revenue. For example, if someone applied a 100% off discount to your order and you receive an order with 0 dollars revenue, Cometly would track 1 purchase for $0 gross revenue.
