Question: is sales revenue and gross profit the same thing

Answer: No, In accounting, gross profit, gross margin, sales profit, or credit sales is the difference between revenue and the cost of making a product or providing a service, before deducting overheads, payroll, taxation, and interest payments. This is different from operating profit (earnings before interest and taxes). Gross margin is the term normally used in the U.S., while gross profit is the more common usage in the UK and Australia.
