Why Invoice Reminders Matter

SMEs lose an average of 12% of revenue to unpaid invoices every year. Not because customers refuse to pay — because they forget.

Manual reminder emails take 15 minutes per invoice. For a business sending 50 invoices/month, that's 12.5 hours spent chasing money you've already earned.

The Right Way to Automate

Most invoice reminder systems fail because they sound robotic. The automation that works:

Step-by-Step Setup

Step 1: Connect Your Invoicing System

n8n can connect to Stripe, e-conomic, Billy, or any system with an API.

Step 2: Build the Reminder Logic

IF invoice.status = 'unpaid' AND days_overdue = 7

THEN send reminder_email_1

Step 3: Write the Email Templates

Keep it human:

"Hi [name], just checking — invoice [number] for DKK [amount] was due last week. Everything okay? Here's the payment link: [link]"

Step 4: Test With Real Data

Send yourself a test. Does it sound like you? Does the link work?

Common Mistakes

1. Waiting too long to send first reminder (day 7 is optimal)

2. Too formal tone (sounds like a collections agency)

3. No payment link in email (adds friction)

Time Saved

For 50 invoices/month:
