How to chase overdue invoices without losing the customer

Updated 3 August 2026 · By the Badger team

Most overdue invoices aren't a payment dispute — they're a priority dispute. Your invoice is at the bottom of someone's pile, and the business that follows up consistently gets paid first. Here's the escalation ladder that gets you there without burning the relationship.

The golden rules

• Chase every overdue invoice, every time. Consistency beats charisma. Customers learn fast which suppliers follow up and which let it slide.
• Start polite, escalate slowly. The first reminder should read like a favour ("in case it slipped through"), not an accusation.
• One message at a time. Never send a second reminder before the first has had a few business days to land.
• Stop the moment they pay. A reminder that crosses a payment is the fastest way to look incompetent. Check before you send, every time.
• Keep every chase in writing. If it ever goes to a collections agency or a tribunal, the paper trail is your case.

The ladder: what to send and when

Timings below assume standard 14–30 day terms; shift them to suit your industry. The full wording for each stage is in our payment reminder email templates.

1. Due date (optional courtesy). "Just a note that invoice #1024 falls due today." Catches the organised-but-busy payer.
2. 3–5 days overdue — the friendly nudge. Assume good faith: the invoice went to spam, the approver was on leave. Attach the invoice again; make paying effortless.
3. 10–14 days overdue — the firm follow-up. Still courteous, now direct: state the amount, the days overdue, and ask for a payment date. Asking for a date matters — a promise creates a commitment you can hold them to.
4. 21–30 days overdue — the warning. Plain language about next steps: suspending further work, charging late payment interest if your terms allow it, or referring the debt on. Send this one from a human, and consider ringing first.
5. 45+ days — final notice, then act. A final notice is only credible if you follow through: collections agency, ASIC-registered debt collector, or for smaller amounts, your state's tribunal (NCAT, VCAT, QCAT and equivalents handle debt claims cheaply).

Handling the classic replies

• "I've already paid." Thank them, ask for the payment date and a remittance or bank receipt, and pause chasing briefly while you check. Verify against your bank — never mark an invoice paid on someone's say-so.
• "Can I pay it off?" A payment plan beats a bad debt. Set your bounds before you answer: minimum upfront, maximum months. Get the schedule in writing and resume chasing the moment an instalment is missed.
• "There's a problem with the work." Split the invoice mentally: resolve the dispute on its merits, and keep the undisputed portion on its payment schedule.
• Silence. Silence is a stage, not a stop. Keep climbing the ladder — most payers respond somewhere on the second or third rung.

Why businesses stop chasing (and the fix)

Nobody starts a plumbing business or a design studio because they love sending awkward emails. The follow-ups feel confrontational, so they get deferred, and the invoice quietly ages past 60 days — where every week off schedule measurably reduces the odds of full payment. The fix isn't more discipline; it's taking the task off a human's plate entirely. That's the job accounts receivable software exists to do: the ladder above, run automatically, politely, and without fail — with you approving what goes out.
