Margin is the difference between a product's (or service's) selling price and the cost.
Margin shows how much profit is left after the cost has been calculated from the selling price. The purchase price of the product can be set in the product database.
If the selling price is added to the product card, the margin field is automatically filled when you are making a quote or an invoice. This makes it easy to see how much profit you're going to make.
In order to view the margin report, go to Reports > Margin report and make a selection from the user, client, project and date range filters.
You can also choose whether the list is filtered by creation date or receipt.
