Short message

Hi Alex, quick reminder that invoice INV-2026-0001 for $2,370.00 is 7 days overdue. Please let me know when payment is scheduled.

Follow-up schedule

  • 3 days before due date: friendly reminder
  • 1-3 days overdue: polite follow-up
  • 7-14 days overdue: firm payment request
  • 30+ days overdue: final notice

Draft a specific payment reminder

Use the generator when an invoice is almost due, recently overdue, or needs a firmer follow-up. Add the invoice number, amount, due date, client name, and payment instructions, then choose a tone that fits the relationship.

How to follow up on unpaid invoices

Start with a calm message that includes the invoice number, amount, due date, and payment instructions. Escalate gradually if the invoice remains unpaid, and make every message easy to forward to a finance team.

When to send each overdue account reminder

This is an example cadence, not a universal rule. Adjust it to the payment terms, relationship, amount, and any client approval process.

Due date or the next business day

Verify the invoice was delivered and that the due date, amount, and payment instructions are correct. For a reliable client, a short receipt check may be more useful than an escalation.

Day 3 to 7

Send the first overdue account reminder. Assume a routing or approval problem, attach the invoice again, name the amount and due date, and ask whether the client needs anything from you.

Around day 14

Send a shorter second reminder. Reference the earlier message, restate the balance, and ask for a specific payment date.

Around day 30

Ask for the accounts-payable contact if you have only been speaking with the project contact, and restate the payment terms shown on the invoice.

Day 45 and beyond

State only the next step the agreement actually supports, such as pausing new work or applying an agreed late fee. Keep the wording factual and avoid threats.

Match the reminder to the timing

Before the due date, keep the message helpful. After the due date, name the outstanding balance. In later follow-ups, include the date of the previous reminder and the next practical step.

A short overdue account reminder example

Subject: Invoice #1042 — $2,370, due 12 September

Hi Dana,

Invoice #1042 for $2,370 was due on 12 September, and I have not seen the payment come through yet. It may be sitting with your accounts team, so I have attached it again.

Could you confirm that it is approved for payment and let me know the date it will go out? If anything is needed from my side, I can send it today.

Thanks,
Alex

The subject identifies the invoice, the first sentence gives the amount and due date, the message leaves room for an approval delay, and the final question asks for one concrete next step. Replace every example detail before sending.

What to avoid

Avoid vague messages such as “just checking in.” Do not use alarming wording or claim a fee unless it was agreed in advance and you have confirmed it is appropriate. Use the late fee calculator only as an arithmetic worksheet, and see the payment reminder email guide for more wording examples.
