CBA Expenses sharing features allow users to create groups for shared expenses, enter new bills with details on who paid and how it should be split (e.g., by percentage or equally), track balances to see who owes whom, and "settle up" by recording cash or online payments to clear debts. The app supports multiple currencies, offline entry, adding pictures of bills, and provides detailed overviews of expenses within groups for various situations like group trips, household expenses, and shared activities.
