An invoice is a request for payment for ONE specific transaction or set of services. A statement is a summary of ALL activity (invoices issued, payments received, balance owed) over a period — usually monthly. Invoices are billing documents; statements are account summaries. This guide covers when to send each, what each should include, sample statement structures, and common confusions like treating a statement like a new bill.
Optional — some clients appreciate the year-end statement showing $0 balance for their records, but it's not required.
Late fees should be applied to the underlying invoice, not the statement. A statement summarises charges that already exist; it doesn't create new charges.
Monthly is standard, usually within the first few days of the new month covering the previous month's activity.
Not in the same way as invoices. Statements are usually labelled by period: 'April 2026 Statement' or 'Q1 2026 Statement'.
