The 3 Golden Rules of Reminder Emails

1
Always reference invoice number and amount

Clients get a lot of emails. If you don't say 'invoice #123 for €1,500' they'll claim they never knew which invoice you meant.

2
Include a payment link in every email

Every extra step between 'read email' and 'paid' costs you. A direct payment link removes all friction. Clients who have to log in to a portal or find bank details often don't.

3
Escalate tone progressively

Don't start with threats. Start warm, get firmer, go formal. Jumping to 'legal action' on day 2 damages relationships. Reserve strong language for 30+ days overdue.

Frequently Asked Questions

When should you send an invoice reminder?

Send the first reminder 7 days before the due date. Then on the due date if it's a large invoice. Follow up 1 day, 7 days, 14 days, and 30 days after due if unpaid.

How do you politely remind a client about an invoice?

Reference the invoice number and amount clearly, use a friendly tone, include a direct payment link, and keep it short. Avoid apologising for chasing — you're owed this money.

How many reminder emails should you send before escalating?

4–5 email reminders over 30 days is standard before escalating to a formal letter or collection. Chaser's 4-stage sequence is built around this framework.

Is it unprofessional to send invoice reminders?

Absolutely not. Sending reminders is normal business practice. 87% of freelancers get paid late — following up is expected. The key is to stay professional in tone.

What subject line works best for invoice reminders?

Include the invoice number and amount in the subject. Clear beats clever: 'Invoice #123 — £850 — due 15 May' performs better than 'Just checking in!'
