3-step follow-up sequence

If the first note gets no reply, a calm escalation on day 3, 7, and 14 after the due date works for most clients. Stop as soon as they pay or reply with a date.

Step 1 · Friendly

Send day 3 after the due date

Subject

Quick reminder: invoice #[number] ([amount])

Body

Hi [Client name],

I hope you're well. This is a friendly reminder that invoice #[number] for [amount] was due on [due date], so it's now 3 days past due.

It may simply have slipped through the cracks. If payment is already on its way, please ignore this, and thank you!

If you need me to resend the invoice or the payment details, just reply and I'll send them straight over.

Thanks so much,
[Your name]

Step 2 · Firm

Send day 7 after the due date

Subject

Invoice #[number] is 7 days overdue

Body

Hi [Client name],

I'm following up on invoice #[number] for [amount], which was due on [due date] and is 7 days overdue. I haven't seen payment come through yet.

Could you let me know when I can expect it? If there's a problem with the invoice or something is holding it up on your side, tell me and I'll help sort it out.

If you need me to resend the invoice or the payment details, just reply and I'll send them straight over.

Thank you,
[Your name]

Step 3 · Final

Send day 14 after the due date

Subject

Final reminder: invoice #[number] ([amount]), 14 days overdue

Body

Hi [Client name],

This is my last reminder about invoice #[number] for [amount]. It was due on [due date] and is 14 days overdue, and I haven't heard back about my earlier messages.

I'd like to settle this simply. Please pay the balance, or reply by [a date a week after you send this] with a date I can expect it. If timing or cash flow is the issue, I'm open to splitting it into installments.

Until it's settled I'll need to pause any new work on the account. I'd much rather keep working together, so please let me know where things stand.

If you need me to resend the invoice or the payment details, just reply and I'll send them straight over.

Best,
[Your name]

Want Chaser to send these for you automatically?

Chaser is a tool we’re building. It will send this same sequence from your own email on the schedule you pick, and stop as soon as the invoice is paid. It’s pre-launch: join the waitlist and we’ll email you once when early access opens.

Tips for getting paid without the awkwardness

Make paying easy. Put the amount, the due date, and a payment link or bank details in every reminder.
Assume good faith first. Most late invoices are forgotten or stuck in someone’s inbox, not refused.
Ask for a date, not just money. “When can I expect it?” gets more replies than “Please pay.”
Escalate calmly. Days 3, 7, and 14 is a common rhythm. Offer installments before anything else.
Stop the moment they pay. A reminder that arrives after payment undoes all the goodwill.
