for this one it keeps track on how much you spend/buy or earn because ... idk for reasons i guess this should work for towny and nations and not only it keeps track if your online but offline (by gaining money from shops while you were offline) and it shows you with a command i think its useful for knowing how much you spend and earn plus i think some people find thsi useful for reasons like to keep track on how much they sell every day (and maybe check if there out of stonks(shorter version: to see if the are bankrupt) ) and also keep track if they are out of stock
