Chasing payment, briefly
How do I ask a client to pay an overdue invoice?
Lead with the facts — invoice number, amount, and due date — keep it short and professional, and make paying a single click. Escalate tone over time: a friendly heads-up before the due date, a neutral nudge just after, then firmer notices that reference your terms and any late fee.
When should I send a payment reminder?
A pre-due reminder 3 days out catches most invoices before they're ever late. After that, nudge around day 2, follow up firmly at day 7, send a second notice naming the late fee near day 14, and reserve formal demand and final-notice language for day 30 and day 60.
Stop sending these by hand — InvoiceHound sends the whole sequence for you and calls it off the minute you're paid.
