When selling goods:

Total revenue = Quantity of goods * Price per goods

When selling services:

Total revenue = Sales of services

Sales are part of revenue. It is the selling price of the goods or services traded. In accounting, total revenue excludes income tax, gain on sale of non-current assets, sales returns, and other transactions. On the other hand, total revenue has sales in the normal course of business, royalties, donations, and rent income.

In investments, high total revenue does not indicate that the company is doing well. Rather, investors and other users of financial statements should analyze the cost of goods or services to get how much is left of the revenue. The residual revenue is called net income or net profit.
