Refunds, compensation, bill credits: gets back every cent you're owed.
Money & bills
Keeps track of every bill, renewal and due date, and reminds you before they hit.
Remembers every payment you have coming up: it finds bills, renewals and charge notices in your connected mailbox, keeps amounts, due dates and payment methods in a table in your knowledge base, and reminds you a few days before each one (set up as a routine). Every so often it looks for subscriptions you're paying twice and plans you're overpaying for, and gives you cheaper options and how to cancel. It never pays anything for you: it reminds, you pay.
