This is a final notice regarding Invoice #{{invoice_number}} for {{amount}}, now 30 days overdue.

3. Apply maximum statutory late payment interest
To avoid these actions, please arrange payment immediately: {{invoice_link}}
If you believe there is an error in this invoice, contact me immediately.

{{your_name}}How to write an invoice email that gets paid
The best invoice emails are short, professional, and make it impossible to ignore the call to action. Here's what every invoice email should include:
Invoice number in the subject
Makes it easy to find in their inbox. Clients process dozens of invoices — be searchable.
Amount in the subject line
Studies show invoices with amounts in subject lines are opened faster and paid sooner.
Due date (always)
Never send an invoice email without the due date visible. Vague = delayed.
One-click payment link
Every additional step between email and payment reduces conversion rate. Chaser generates a direct payment link for every invoice.
PDF attachment
Even if you include an online link, always attach the PDF. Finance teams need it for their records.
The 4-touch follow-up sequence that works
Research shows that 80% of overdue invoices are collected within 4 reminders. The key is escalating tone — each email is slightly firmer than the last:
Friendly nudge
Assume it was forgotten. Polite, no pressure.
Polite but clear
Restate invoice details. Ask for confirmation.
Firm
Mention late payment fees. Set a new deadline.
Final demand
Collection agency or court mentioned. Non-negotiable.
Chaser automates this entire sequence. Create the invoice, send it, and Chaser monitors the due date. If unpaid, it fires all 4 emails automatically — you're cc'd but never need to write a word.
Tone guide: how firm is too firm?
Common mistake: freelancers either never follow up (too soft) or jump straight to threats (too hard). The right escalation looks like this:
| Timing | Appropriate tone |
|---|---|
| Invoice day | Warm, professional, brief |
| 3 days overdue | Friendly — assume it slipped through |
| 7 days overdue | Professional — ask for confirmation timeline |
| 14 days overdue | Firm — mention consequences, still professional |
| 30 days overdue | Formal, direct, action-oriented |
| 60+ days overdue | Legal/collection language appropriate |
Frequently asked questions
What should I write in an invoice email?+
Your invoice email should include: the invoice number, total amount due, due date, a PDF attachment, and a professional but friendly message. Keep it brief. Something like: 'Hi [Name], please find Invoice #[number] for [amount] attached, due [date]. Let me know if you have any questions.' Chaser generates this email automatically when you send an invoice.
How do I write a professional invoice email subject line?+
The best invoice email subject lines are clear and specific: 'Invoice #[number] for [project] — Due [date]' or 'Payment Request: [amount] Due [date]'. Avoid vague subjects like 'Invoice attached' as they can be missed. Including the amount in the subject line has been shown to increase open rates.
How do you politely follow up on an unpaid invoice?+
Send a polite reminder 3-5 days after the due date. Keep the tone professional and assume the oversight was accidental: 'Hi [Name], I wanted to follow up on Invoice #[number] for [amount], which was due on [date]. Could you confirm when payment will be processed?' Avoid accusatory language. After 2 reminders with no response, it's appropriate to firm up the tone.
How many invoice reminder emails should I send?+
Most successful collection sequences use 4 touch points: a 3-day polite nudge, a 7-day second reminder with the invoice details restated, a 14-day firmer notice mentioning late payment fees, and a 30-day final demand before escalating. Chaser's automated reminder sequence follows exactly this pattern — all 4 emails sent automatically when an invoice goes overdue.
Can I automate invoice reminder emails?+
Yes — and you should. Chaser sends automatic payment reminders at Day 3, 7, 14, and 30 after the due date. Each email escalates in firmness while staying professional. You don't have to write or send any of them. Just mark the invoice as sent, and Chaser takes over if payment doesn't arrive.
