When an invoice goes unpaid, a well-written collection letter can get you paid without damaging the client relationship. Here are templates for each stage.
"Hi [Client Name], I wanted to follow up on invoice [INV-XXX] dated [date]. It may have slipped through the cracks — no worries at all. Please let me know if you have any questions about the charges. You can pay here: [payment link]. Thank you!"
"Hi [Client Name], invoice [INV-XXX] for [$X] is now [X] days past due. As per our agreement, a late fee of [X%] will be applied starting [date]. I would really appreciate your attention to this. Please make payment at: [link]."
"This is the third and final notice regarding invoice [INV-XXX] for [$X], now [X] days past due. If payment is not received by [date], I will refer this to collections. You can still resolve this immediately by paying here: [link]."
