Client Owes Money: What to Email (Free Script)

When a client owes you money, the first email should not be a fight. Restate the invoice, make paying one click, and ask for a date. Most late payments are process problems, not bad intent—your email should make the fix easy.

Hi [Client Name],

Please reply with the date payment will clear, or let me know if something on the invoice needs fixing. Happy to correct details the same day.

What to do before you hit send

• Confirm the invoice was sent to the right person (and CC accounts payable if you have them).
• Check your bank/processor for partial payments or failed card attempts.
• Pull the contract or SOW so you know due date, late fees, and pause-work rights.
• Decide your next step if they ignore this email (second reminder, 30-day firm note, or payment plan offer).

If they say they already paid

Thank them, ask for the payment method, confirmation number, and date. Offer to check your side the same day. See the payment promised but not received guide if nothing shows up.

When to escalate

• No reply after this email: send a second payment reminder a few business days later.
• 30+ days: use the 30 days overdue script and ask for a hard date.
• They need time: offer a short written payment plan instead of an open-ended extension.
