"Checking account" to keep track of future buys/sells (Little Upsilon)

I realize if you have been playing this game for 5+ years, you are probably used to every quirk of the interface. However, please try to look at this from a new user's perspective:

Let's say I make 12 corporations for my new country. Every one of those corps is absolutely, 100% free in $SC. The only visible cost is workers, which you don't need at first anyway.

Then suddenly, a few months later, I have no money! What happened??!

What happened is that corps DO cost money. But the game doesn't tell you how much, and it doesn't subtract it from your balance.

In real life, this is how people overdraw their checking accounts. It's why they created something called a "checkbook" where you write down FUTURE purchases that you *know* are going to happen.

Since 99% of the transactions in this game take place at least 1 month in the future, wouldn't it make sense to h

Example: Let's say I have 3000 jeeps and $1bn.

I offer to sell 500 of them. Market price at the time is $1m each, so I will profit $500m.

This sale could take months to happen. In the meantime, it should say how much I have, and (how much I will have)

Jeeps: 3000 (2500)

and

Cash on Hand: $1bn ($1.5bn)
