Somebody's already put money down
A plan moves nobody's balance — with one exception. A deposit is real money that's already gone, so it goes into the balances the day it goes down.
Somebody paid in February. Half the house, on their own card, to hold it. It is now July, and they have brought it up four times, each time a little more precisely, and each time everyone has said absolutely, we’ll sort that out.
Nobody has sorted that out.
Here’s the thing a plan normally does, which is nothing. It sits there with a date and a price and a guest list, and it moves no balances, enters no settlement, and is in nobody’s total. Nothing is owed on a plan. That’s the whole point of it being a plan.
A deposit is the exception, because a deposit isn’t a plan. It’s money that has already left somebody’s account and, depending on the somebody, is currently accruing interest at a rate nobody wants to say out loud.
So on the planned path, after you’ve put a price in, there’s a step asking whether anyone’s paid toward it yet. Put the deposit in there and it stops being hypothetical: it becomes a real, confirmed expense right then, attached to the plan, and it lands in everyone’s balances that day. The rest of the plan stays an estimate, because the rest of it is still a guess.
It also comes out of the committed figure — the amount your budget holds back for things you’ve promised. Money you’ve already handed over isn’t money you still have to find, so it isn’t held twice.
And when the thing finally happens and you confirm the plan, it knows what’s already down. It subtracts it, asks who covered the remainder, and shows you exactly where each party lands — owed, owes, or square — before you save anything.
I was in the hall in February when that card came out, and I was in the hall again in July when it came up for the fourth time. I remember both perfectly. Nobody has ever asked me.
