Write Professional Follow-Up Emails for Overdue Invoices

**Subject:** Second Reminder – Invoice #2045 Overdue (Past Due by 12 Days)

Dear Brightline Marketing Team,

I hope you're doing well. I'm following up on my previous email from last week regarding Invoice #2045 for **$3,750**, which was due on **October 15th** and is now **12 days overdue** under our net 30 payment terms.

As we haven't yet received payment or a response to our earlier message, I wanted to reach out personally to ensure the invoice didn't get missed. We truly value our partnership over the past eight months and want to make settling this as easy as possible for you.

Could you kindly arrange payment by **November 3rd**? You can pay directly via the secure link in the original invoice, or reply to this email to confirm the expected payment date.

If there are any questions, discrepancies, or issues on your end that we can help resolve, please let me know — I'd be happy to jump on a quick call.

Thank you in advance for your prompt attention.

Best regards,
