Subject: Payment Follow-Up – Invoice INV-1048 Now 30 Days Overdue
Hello Alex, I am writing about invoice INV-1048 for CAD 2,500.00, originally due on August 26, 2026. As of September 25, it is 30 days overdue. Please give this outstanding payment your immediate attention and arrange payment as soon as possible. Could you also confirm the date we can expect payment? If anything is delaying payment, please let us know what is needed from our side. If payment has already been processed, please share the payment date and reference so we can check our records. Thank you, Morgan Smith Consulting
Subject-line examples
- Payment Follow-Up – Invoice INV-1048 Now 30 Days Overdue
- Payment Status Requested – Invoice INV-1048
What to include
- The customer name, invoice number and outstanding amount in the correct currency.
- The original due date and actual number of days overdue.
- A direct payment request and a request for a specific expected payment date.
- An invitation to identify any invoice question or obstacle.
Check your records before sending. If part of the invoice has been paid, request only the remaining balance and acknowledge that payment.
Appropriate tone: Immediate Attention
Use short, factual sentences. “Please confirm the payment date” is clearer than “Please deal with this soon.” A date gives both sides something concrete to work with. If the reply only says the invoice is being processed, ask when processing is expected to finish.
Common mistakes
Avoid anger, accusations and unsupported threats. Do not write “as repeatedly requested” unless you can confirm that history. Do not add fees or consequences just because 30 days have passed. Use the agreed due date, not the invoice issue date, to calculate how late payment is.
Questions about this situation
How firm should a 30-day overdue invoice email be?
Be direct about the outstanding balance and ask for a payment date. Keep the language courteous and leave room for the customer to identify a genuine problem.
What should I ask the customer at 30 days overdue?
Ask whether the invoice has been received and approved, whether payment is scheduled, and on what date it will be made. Ask what is needed if payment is blocked.
Should I mention late fees?
This tool does not add late fees. Do not assume a charge applies based on elapsed time. Confirm your agreement and obtain appropriate advice before adding any charge yourself.
Related guidance
If the invoice has been outstanding longer, see the 60-day follow-up guidance for asking about approval and documentation delays.
