Different audits have different requirements, so it depends on what company you are doing them for. Most require a purchase in the convenience store, and possibly a gas purchase, too. Some do not require a purchase. Usually, you must take photos. How many photos are required and what subjects differs depending on the gas station. If you want more detail, you might have to tell us which one you are interested in. Or, you could try one nearby and see for yourself what it's like before you schedule any others.
