3 Days Before Due Date
Quick heads up: Invoice [#INV] due in 3 days
Hi [Client Name], Just a friendly heads up that invoice [#INV] for [AMOUNT] is coming due on [DUE DATE]. If you've already scheduled the payment, you can ignore this message. If you need the invoice resent or have any questions, just let me know. Thanks, [Your Name]
When to use: Send to all clients as a courtesy. This is a soft nudge, not a demand — it prevents the "I forgot" excuse before it happens.

Hi [Client Name], This is a reminder that invoice [#INV] for [AMOUNT] is due on [DUE DATE] — three days from now. Please ensure payment is submitted by the due date to avoid any late fees per our agreement. If you have any questions about the invoice, please reach out before the due date. Payment can be sent via [PAYMENT METHOD]. Best regards, [Your Name]
When to use: Use with clients who have a history of late payments, or for large invoices where you want to set a firm tone early.

Following up: Invoice [#INV] — 7 days past due
Hi [Client Name], I wanted to follow up on invoice [#INV] for [AMOUNT], which was due on [DUE DATE] — now seven days ago.

14 Days Overdue
Checking in: Invoice [#INV] — 2 weeks overdue
Hi [Client Name], I'm reaching out again about invoice [#INV] for [AMOUNT], originally due on [DUE DATE]. It's now been two weeks since the due date.

When to use: Use when previous emails have been ignored. The mention of pausing work and escalation signals you're serious.
30 Days Overdue
Invoice [#INV] — 30 days overdue, let's resolve this
Hi [Client Name], I've reached out several times about invoice [#INV] for [AMOUNT], which is now 30 days past the due date of [DUE DATE]. I value our working relationship and would like to resolve this amicably. If the full amount isn't possible right now, I'm happy to discuss a payment plan. But I do need to hear from you. Could you reply today with a payment date or to let me know what's going on? Thank you, [Your Name]
When to use: Use when you want to preserve the relationship but need to make clear that 30 days is a serious milestone. Offering a payment plan shows flexibility.
Final reminder before escalation: Invoice [#INV] — 30 days overdue
Dear [Client Name], Invoice [#INV] for [AMOUNT] has been overdue for 30 days. Multiple reminders have been sent without response or payment. This is a final reminder before I escalate this matter. If payment is not received within 7 calendar days, I will: 1. Suspend all current and future work. 2. Apply all accrued late fees to the balance. 3. Refer this matter to a collections agency or pursue legal remedies. To resolve this immediately, please remit payment via [PAYMENT METHOD] or contact me to arrange a payment plan. Sincerely, [Your Name]
When to use: Use when all previous attempts have failed. This is your last email before actual escalation — be prepared to follow through on the stated consequences.
60 Days Overdue
Invoice [#INV] — 60 days overdue, last attempt to resolve directly
Hi [Client Name], It's been 60 days since invoice [#INV] for [AMOUNT] was due, and I haven't been able to reach you. I would genuinely prefer to resolve this between us rather than involve a third party. If you can commit to a payment date — even a partial payment to start — I'm willing to work with you. This is my last attempt to resolve this directly. If I don't hear back within 5 business days, I'll need to take the next steps outlined in our agreement. [Your Name]
When to use: Use as a genuine last attempt before collections. The personal tone sometimes breaks through where formal emails haven't.
Formal notice: Invoice [#INV] referred for collection — [AMOUNT]
Dear [Client Name], This letter serves as formal notice that invoice [#INV] for [AMOUNT], originally due on [DUE DATE], is now 60 days past due. All previous attempts to resolve this matter have been unsuccessful. Effective immediately, this account is being referred to [collections agency / legal counsel] for recovery. The total amount due, including accrued late fees of [LATE FEE AMOUNT], is [TOTAL AMOUNT]. If you wish to resolve this matter before it proceeds further, full payment must be received within 5 business days of this notice. Contact [PHONE/EMAIL] to arrange payment. This is not a matter I take lightly, and I would prefer a resolution without further action. Sincerely, [Your Name]
When to use: Use when you have actually engaged a collections process or attorney. Never bluff about collections — only send this when you are prepared to follow through.
