7 Invoice Follow-Up Email Templates That Get You Paid (Copy & Paste)
When a client hasn’t paid, the hardest part isn’t sending the follow-up — it’s deciding what to write. Say too little and they ignore it. Say too much and you damage the relationship.
Below are 7 invoice follow-up email templates you can copy, paste, and send today. Each is written for a specific scenario: from the first friendly nudge to the final notice before collections. Every one has been used by small businesses to actually recover money.
Replace the bracketed placeholders ([Name], [Invoice #], etc.) with your client’s info and you’re ready to send.
1. The friendly reminder (3–5 days past due)
Most late payments are genuinely forgotten. A short, warm email solves this 60–70% of the time.
Subject: Quick reminder — Invoice #[Invoice number]
Hi [Name],
Just a friendly reminder that Invoice #[Invoice number] for $[Amount] is a few days past due. If it’s already on the way, please disregard!
Otherwise, here’s the payment link: [link]
Thanks,
[Your name]
2. The 14-day follow-up
Two weeks in. At this point you want to be warm but clearly reference the specific invoice and a new payment date.
Subject: Following up on Invoice #[Invoice number]
Hi [Name],
I wanted to circle back on Invoice #[Invoice number] for $[Amount], which is now 14 days past due. Could you share an expected payment date?
If there’s anything blocking payment on your end — a question about the work, a missing PO, anything — I’m happy to help resolve it.

Thanks,
[Your name]
3. The 30-day follow-up (firmer tone)
30 days is when the tone shifts from reminder to expectation. State the overdue period clearly and add a deadline.
Subject: Invoice #[Invoice number] — 30 days overdue
Hi [Name],
Invoice #[Invoice number] for $[Amount] is now 30 days past due. I’d appreciate payment by [specific date 7 days out] to keep our account current.
If there’s an issue I should know about, please reach out so we can resolve it.
Payment link: [link]
Best,
[Your name]
4. The "checking in" (when you’ve heard nothing)
For clients who have gone silent. Soft but names the silence directly.
Subject: Haven’t heard back — Invoice #[Invoice number]
Hi [Name],
I haven’t heard back on my last two messages about Invoice #[Invoice number] ($[Amount], now [X] days overdue). Just want to make sure my emails are reaching you.
Could you confirm you’ve received this and let me know when we can expect payment?
Thanks,
[Your name]
5. The payment plan offer
If a client mentions cash flow issues, offering a payment plan often recovers more than pushing for the full amount.
Subject: Invoice #[Invoice number] — payment options
Hi [Name],
Thanks for letting me know about the cash flow situation. To keep the account moving, I’m happy to break Invoice #[Invoice number] ($[Amount]) into three payments of $[Amount/3] — due over the next 90 days.
Would that work on your end? If so, I’ll send the first installment link today.
Best,
[Your name]
6. The final notice (45–60 days)
This email signals the end of the friendly chase. Clear, professional, and not hostile — but firm about next steps.
Subject: Final notice — Invoice #[Invoice number]
Hi [Name],
Invoice #[Invoice number] ($[Amount]) is now [X] days overdue. Despite several follow-ups, I haven’t received payment or a response.
This is my final notice before escalating the matter. Please pay by [specific date 5 days out] to avoid additional steps.
If you’re experiencing a problem I can help with, please reply directly.
Payment link: [link]
[Your name]
7. The thank-you (after they pay)
Always close the loop. A thank-you email rebuilds the relationship after a tense collection and reinforces the expectation for future invoices.
Subject: Payment received — thanks!
Hi [Name],
Confirming I’ve received your payment for Invoice #[Invoice number]. Appreciate you getting it sorted.
Looking forward to the next project.

Tips for making every follow-up email work
- Always reference the invoice number and exact amount. Vague "just checking in" emails get ignored.
- Include a payment link — every click of friction loses some percentage of recoveries.
- Send from your own email address, not a generic billing one. Personal > transactional.
- Keep each email short. Under 80 words, whenever possible.
- Send on a Tuesday or Wednesday morning. Response rates drop significantly on Mondays and Fridays.
Pro tip: The best follow-up strategy isn’t about the perfect template — it’s about consistency. Businesses with automated follow-up sequences recover 2–3x more than those relying on memory. RecoverInvoice connects to QuickBooks and drafts personalized versions of these exact templates for every overdue invoice, then sends them from your Gmail or Outlook on approval.
When to stop following up and escalate
If you’ve sent three follow-ups over 60+ days with no response, it’s time to move on to:
- A phone call. Email is easy to ignore, a live call isn’t.
- Small claims court (for invoices under $10,000 in most US states).
- A collections agency for larger amounts. Expect them to take 20–50% of what they recover.
- Write-off and move on. Sometimes the cost of chasing exceeds the invoice. Track chronic late payers and avoid similar terms with them going forward.
The bottom line
Follow-up emails work. Most small businesses that switch from sporadic follow-ups to a consistent 3-email sequence recover significantly more money — often within days of the first send. Save these templates, adapt them to your voice, and send them at the right intervals.
Or, if you don’t want to remember to do it every week: connect RecoverInvoice to your QuickBooks and we’ll draft and send every follow-up for you. You approve each one before it sends.
