Use these templates when the invoice is officially overdue and you need a clear payment date without escalating too fast.
Replace the placeholders, adjust the amount or date, and send only after the policy and invoice details are correct.

Insight
The main job of an overdue follow-up is to get a payment date or expose the real blocker. That is why these templates ask for a clear timing answer instead of only repeating that the invoice is late.
Keep the tone factual so the client can reply with the next step instead of getting defensive.
FAQ
Ask for the expected payment date. That creates a clearer commitment than a generic request to pay soon.
Yes. Reattaching the invoice removes one common excuse for delay and makes the next action easier for the client.
