Overdue Invoice

An overdue invoice has passed its due date without full payment.

  • —Verify the invoice is complete before chasing payment.
  • —First reminder should be polite and specific.
  • —Escalate gradually and document each touchpoint.

Check the invoice first

Before chasing payment, confirm the due date, amount, client contact, and whether a PO or approval was required. Many overdue invoices are stuck in AP because of a missing field, not because the client refuses to pay.

  • Confirm due date and amount
  • Check PO requirements
  • Verify client contact and inbox

Send a polite reminder

Reference invoice number, amount, original due date, and days overdue. Ask if anything is blocking payment and offer to resend documentation or split payment if appropriate.

  • Invoice number and balance
  • Days overdue
  • Offer to fix blockers

Escalate gradually

If reminders fail, escalate tone, involve the project sponsor, or pause new work per your contract. Document each follow-up. Late fees should only be mentioned if they were agreed upfront.

  • Pause new work if contract allows
  • Involve project sponsor if needed
  • Only cite late fees if pre-agreed
