SubjectInvoice #2026-041 — payment reminder
How to use it well
- →Send the first reminder within a week of the due date — waiting a month signals the deadline was soft.
- →Keep the good-faith framing on reminder one; save escalation (late fees, pausing work) for reminders two and three, each firmer than the last.
- →Always restate number, amount and due date — the goal is that paying requires zero archaeology on their side.
Part by part
- issued on {{issue_date}}, was due on {{due_date}}
- Both dates, which establish that the payment is genuinely late rather than merely outstanding. It is the factual basis for everything that follows.
- It may simply have been missed
- Gives an innocent explanation, which is usually the true one and which makes it easy to pay without anyone losing face.
- If payment is already on its way, please ignore this note
- Removes the awkwardness of a reminder crossing a payment in transit, which happens often enough to be worth pre-empting.
- Could you let me know when I can expect it?
- Asks for a date rather than for payment. A commitment to a date is easier to give and much easier to follow up on.
Common mistakes
Demanding immediate payment on the first reminder.Most late payments are administrative rather than deliberate, and an aggressive first note damages a relationship over something that was about to be resolved anyway.
Waiting a month before following up.Invoices age badly — the longer one sits, the more likely the person who approved it has moved on. A polite reminder a few days after the due date is normal and expected.
Not attaching the invoice again.The most common reason for non-payment is that the invoice is not in front of the person who can pay it. Attaching it removes the step that was blocking them.
Questions
How soon after the due date should this go?
Two or three days. Late enough to allow for processing, early enough that the invoice is still recent — and it establishes that you track payment dates, which affects the next one.
What if there is still no response?
Escalate in steps: a second reminder, then a phone call, then a formal notice referencing your terms. Each step should reference the previous, which is what builds the record if it goes further.
Should I mention late payment interest?
Not on the first reminder unless your terms state it clearly. Raising it early converts a routine chase into a dispute; referencing it later, once you have been patient, carries much more weight.
How do I avoid this happening?
Clear terms on the invoice, payment details on every copy, and knowing who actually processes payments rather than who commissioned the work. Most delays are a routing problem rather than a willingness one.
