Broken Promise Payment Follow-Up Email Template

Example email

Hi [Client],

When we spoke on [date], you mentioned payment for invoice #1042 would arrive by [agreed date]. That date has passed and I haven't seen it come through.

I know things come up, so I'm not worried — just checking whether the timeline has shifted. Can you give me an updated ETA?

Thanks,
[Your name]

How many times should I follow up on an unpaid invoice?

A standard escalation sequence has three steps: (1) a gentle reminder 1-3 days after the due date, (2) a firm follow-up 7-14 days later, and (3) a final notice at 21-30 days with clear consequences. After that, you may need to pause work or escalate to formal collections.
