3 days before due date
Subject: Invoice {{number}} due {{due_date}}
Hi {{first_name}},
Quick heads-up that invoice {{number}} for {{amount}} is due on {{due_date}}. I've attached a copy for convenience.
If anything needs changing — a PO number, a different billing contact — just let me know and I'll reissue it today.
Thanks,
{{your_name}}1–3 days overdue
Subject: Invoice {{number}} — now due
Hi {{first_name}},
Invoice {{number}} for {{amount}} was due on {{due_date}} and I don't have it marked as paid yet. It's very possible it's already in your payment run — if so, ignore this.
If it hasn't been scheduled, could you let me know roughly when to expect it?

Subject: Invoice {{number}} — 14 days overdue
Hi {{first_name}},
Invoice {{number}} for {{amount}} is now 14 days past its {{due_date}} due date and remains unpaid.
Could you confirm today either that payment has been scheduled, or what's holding it up? If it needs to go to someone else in accounts payable, send me their address and I'll deal with it directly.

Subject: Invoice {{number}} — 30 days overdue, work paused
Hi {{first_name}},
Invoice {{number}} for {{amount}} is now 30 days overdue.
Per our agreement, I'm pausing further work on {{project}} until the balance is settled, and a late fee of {{late_fee}} applies from {{late_fee_date}}.
I'd much rather keep things moving. If you can confirm a payment date this week, we'll carry on as normal.

Subject: Final notice before collection — invoice {{number}}
Hi {{first_name}},
Invoice {{number}} for {{amount}}, issued {{issue_date}} and due {{due_date}}, remains unpaid after several reminders sent on {{reminder_dates}}.
This is a final notice. If payment or an agreed payment plan isn't in place by {{deadline}}, I'll pass the invoice to a collections agency / file in small claims court, and any recovery costs will be added to the balance.
I'd still prefer to resolve this directly. Reply today and we can.

Subject: Should I close the file on invoice {{number}}?
Hi {{first_name}},
I haven't heard back on invoice {{number}} for {{amount}}. I'm going to assume one of three things is true:
1. It's scheduled and I just don't have visibility — reply "1" and I'll stop chasing.
2. There's a dispute with the work or the amount — reply "2" and I'll call you today.
3. Cash is tight right now — reply "3" and we'll agree a payment plan.
Any of those is fine. Silence is the only one I can't work with.
Thanks,
{{your_name}}Keep it short, state the invoice number, amount and original due date, give the client one specific action, and set a date for their reply. Escalate tone over time rather than opening with anger — most late payments are administrative, not malicious.
A workable cadence is a reminder three days before the due date, then on day one, day seven, day fourteen, day thirty, and a final notice around day forty-five. Automating the first three removes the emotional decision of whether to chase.
You can if your contract or invoice terms say so and the rate complies with your state's law on interest and finance charges. Common practice is 1–1.5% per month. Announce the fee in the contract before the work, not in the reminder email.
Options are a collections agency (typically taking a percentage), small claims court for amounts under your state's limit, or writing it off as a bad debt. Before any of those, one phone call resolves more invoices than five emails.
