When you take a pool payment, it goes into a pool balance. This isn’t money earned- its a deposit set aside for future services, just like a lawyer might require a minimum retainer that they can bill against for services in the future. At the end of the day, another transaction is run against each active client for the daily rate amount. This second transaction is actually ‘income earned’: services have been rendered for the day and that money is deducted from the pool.
All of these transactions need to be accounted for- including the transaction of your organization ‘earning’ the money for services rendered. Hence why you see a bunch of daily rate ‘invoices’ (they are actually better classified as transactions) show up.
