These scripts are built for the exact scenario: net 30 overdue what to send. Keep each message short, include payment details, and ask for one clear next action.

Day 1 / 7 / 14 / 30 scripts

Day 1 (friendly)

"Hi [Name], quick reminder that invoice #[number] for [amount] is now past Net 30. Payment link: [link]. If already paid, thank you and please ignore this."

Day 7 (direct)

"Hi [Name], following up on invoice #[number], now 7 days overdue. Can you confirm the payment date today? Payment link: [link]."

Day 14 (firm)

"Hi [Name], invoice #[number] remains unpaid after prior reminders. Please process payment by [date]. If there is a blocker, reply today with details."

Day 30 (final-stage)

"Hi [Name], this is a final-stage reminder for invoice #[number], now 30 days overdue past Net 30. Please pay by [date/timezone] to avoid next-step escalation."

For expanded schedule guidance use unpaid invoice follow-up schedule.

The “talk to finance” script

"Thanks for the update. Please share the best AP/finance contact and I will send full details directly. I’ll include invoice #[number], amount, due date, and payment link so this can be processed quickly."

For AP-ready wording use email to accounts payable overdue invoice.

The “pause work” script

"To keep billing aligned, I will pause new work from [date] until invoice #[number] is settled. Once payment is received, I can resume immediately and confirm updated delivery timing."

This keeps boundaries professional without emotional language.
