Every dollar lives in an envelope. Every transaction is assigned to an envelope.
Money in your accounts is divided into envelopes, one for each thing it is for. Your envelopes and your Inbox always add up to the cash you actually have.
A new transaction waits in your Inbox until you assign it. Nothing is assigned for you unless you set a rule, and nothing quietly disappears.
Set your income dates and a budget for each envelope, then fund them from the plan when the money arrives.
