I worked on a QBO file for a law firm, where they used the AR sub-ledger to keep track of client retainer accounts. Retainers received were posted using Receive Payments creating a credit which meant that most clients had negative AR balances, to which invoices were applied. This is not technically correct (negative AR), but it worked in terms of keeping separate ledger pages for each client. A reversing JE had to be done at year end, and reversed the next day, to temp move the total negative AR balance to the liability, so the b/sheet was accurate at year end.
