Casual staking falls apart on exactly that question. The Backer Hub answers it on its first screen: owed to you, you owe, net position, then every open balance as a queue with the age on each row. The settle-up becomes arithmetic instead of a negotiation.

Every deal carries its percentage, markup and event. Cashes split themselves against the terms the moment a result lands, and both sides see the same number, which is the entire point.
