Hi all im new to here. My name is sanjana and im implementing a software for an animal hospital. Do note that my accounting knowledge is just basic because my major is computer science. i need to know what are the standard things that should come inside the profit and loss sheet. currently i have added revenues,cost of sales,gross profit,other operating exp,marketing selling & distribution expenses and administrative expenses. what else should be there? i have attached a screenshot of the balance sheet and profit & loss.
