Business expenses that you are later reimbursed for and the reimbursed deposit should be categorized as Reimbursements to ensure those transactions do not count against your spending or income. This category makes it easy to keep track of these expenses while not throwing off your budget.
Shared bills that you receive payments for should not count towards your earnings, as that transaction is used towards payment of your bills. To adjust the category, tap on the transaction and from there you will be able to update the transaction to Bills & Utilities. This will then ensure these transactions subtract from your overall bill expenses.
An example of a shared bill would be your roommates paying you for their share of the rent. Your rent payment is categorized as Bills & Utilities, you should then also set their payments to Bills & Utilities - this way, Rocket Money will automatically balance everything out and show you exactly how much you're truly spending on rent.
