Invoice INV-0042: payment reminder
Send
Hi Northwind Studio,

Invoice INV-0042 for USD 2,400.00 was due on October 20, 2026. I don't have the payment on my side yet.

Probably an oversight, so here are the details again:

Amount: USD 2,400.00
Reference: INV-0042
Pay to: details on the invoice (attached again)

If it has already gone out, send me the transfer date and I'll match it on my end.

Thanks,
Alex Rivera

Still not paid after Day 30?

That is when another email stops working. The Late-Payment Rescue Pack has what I send when a client goes quiet:

  • A formal final notice letter in Word, ready to sign and send as a PDF.
  • Emails for charging a late fee and agreeing a payment plan, in English and Spanish.
  • Late payment clauses and a freelance contract so it does not happen again.
