It's stupid that the program doesn't show a preview of all transactions that will be executed before it does them. My online banking has that, I don't get why

It's stupid that the program doesn't show a preview of all transactions that will be executed before it does them. My online banking has that, I don't get why software for managing 900m dollar loans doesn't have that. What good is it if you require three people to sign off on the transaction when noone actually looks at the transactions!!
