Late fee applied: updated invoice wording

Wording for the updated invoice once an agreed late fee has been added, with itemised maths.

“The longer and softer you make it the more it reads like you think you're being unreasonable for wanting to get paid.” This one is short and direct, with no “sorry to bother you”.

Show the maths and refer to the agreed term. Offering a one-time waiver for fast payment often closes it.

Subject: Updated invoice [INV-123] — late fee added

Hi [Name],

As invoice [INV-123] remains unpaid [x] days after the due date, the agreed late fee (clause [x]) now applies:

  Original: [amount]
  Late fee ([rate] × [period]): [fee]
  Total due: [total]

Updated invoice attached. If the original [amount] is paid by [date], I'll waive the fee this once: [payment link].

Thanks,
[Your name]
