Chasing a late invoice without losing the client

Most late payments are not refusals. They are an invoice that never reached the right person, sat in an approval queue, or missed a payment run by a day. That is worth remembering before you write the first chase, because the tone that assumes a mistake gets paid faster than the tone that assumes bad faith.

Before it is late

A short note a few days before the due date is the single highest-return message you can send. It is not chasing, it is a reminder, and it catches everything stuck in somebody’s inbox while there is still time to fix it.

The sequence

• Day 1 past due. Short, friendly, assume an oversight. Re-attach the invoice. Ask them to confirm it has been received and approved.
• Day 7. Slightly firmer, still warm. Ask a specific question: has it been approved, and if so, which payment run is it in? Questions get replies; statements get ignored.
• Day 14. Pick up the phone. One call at this stage is worth six emails, because it finds the actual blockage.
• Day 30. Formal. State the amount, the days overdue, and what happens next: work paused, late fee applied, account on hold.
• Day 45 and beyond. Stop sending polite emails. Escalate to whoever signs off, or accept that you are now deciding whether to pursue it.

Chase the oldest first

When several invoices are late, work the oldest, not the largest. Debt gets harder to collect the longer it sits, and a ninety-day invoice is a materially worse position than a thirty-day one of twice the value.

Make it easy to say yes

Every chase should carry the invoice number, the amount, the due date and the payment details. If the reply has to be “can you resend it”, you have added another week for no reason.

Notice the pattern

A client who is always thirty days late is not late, they are on sixty-day terms and have not told you. Price it in, shorten the terms, or ask for a deposit. A client who goes quiet is a different problem, and the answer to that one is usually to stop working before the balance grows.
