Help with city ledger or guest ledger?

My family has a small buss. so i helped them by setting sambapos for the restaurant and the cashier asked me if there is an option of city ledger or guest ledger because some of my family member order stuff but doesnt pay at the moment so he needs to put them in the report like if i took something and press cash he presses something else like my name for example and it has another report for it … he called it cl too

Do you mean something like that?
