The Payouts page only shows money Storedoor collected for you and now owes you. A sale rung up at your register is paid to you directly, in cash or on your own card machine, and the same is true of an order paid in cash at the door. In both cases the money is already in your hand.
So those orders are left out of your payouts on purpose. Adding them would show you a balance to withdraw for money you already have.
They are still full orders in every other way: they show in Orders, they count in your reports, and your stock moves for them. If your payout balance looks lower than your sales, open Orders and check the Source and Payment Method columns first. That is usually the whole answer.
