Day 16 — Polite check-in

Hi {{Name}},

Just checking in on Invoice {{InvoiceNumber}} ({{Amount}}), which was due {{DueDate}}. Can you confirm when payment is scheduled?

If you need anything from my side to process it, I can send it today.

Thanks,
{{YourName}}

Day 20 — Firm (one clear ask)

Hi {{Name}},

Following up on Invoice {{InvoiceNumber}} ({{Amount}}), now overdue since {{DueDate}}.

Please reply with either:
(a) confirmation it’s been paid (and any reference), or
(b) the exact date you can commit to.

Best,
{{YourName}}

Day 30 — Escalation-ready

Hi {{Name}},

Invoice {{InvoiceNumber}} ({{Amount}}) is now 30+ days overdue.

To close this out, please confirm payment today or provide a firm payment date.

If we don’t have confirmation by {{DeadlineDate}}, we’ll need to move to our next step per our process.

Regards,
{{YourName}}

Make it work better (fast tips)

Ask for one thing: a confirmed payment date.
Keep the first line factual (invoice #, amount, due date).
Mirror their promised date in your reply to lock it in.
Escalate tone gradually: polite → firm → next step.
