How to reply to a late payment reminder you received

Updated November 12, 2026

Reply the same day, even if you cannot pay yet. Say which invoice it is, then do one of three things: confirm payment with a date, ask for a short extension with a firm date, or point to proof that you already paid. Silence makes a late bill worse. A short honest reply keeps the relationship safe.

Reply

Same day. A reminder means they are already waiting. Replying quickly, with a date, usually stops the next, firmer notice.

What your reply should say

1. Name the invoice number and amount, so there is no confusion about what you mean.
2. Say plainly whether you are paying, need more time, or already paid.
3. Give a specific date for payment, or attach proof of the payment you made.
4. Ask them to confirm receipt, and say how to reach you if anything is wrong.

Hi [Name],

Thank you for the reminder about invoice [number] for [amount]. I am sorry it is late.

I cannot pay it in full today. I can pay [amount] on [date] and the rest by [date]. I will keep to those dates.

If that is not workable, please tell me what would be, and I will do my best.

Hi [Name],

Thank you for your message. I paid invoice [number] for [amount] on [date] by [method]. The reference is [reference], and I have attached the confirmation.

Could you check your account and confirm that it has arrived? If it has not, tell me which details you see and I will trace it with my bank.

Thank you.

Already late? Send this instead

For when you are a week or more after a second notice late or more. Own the delay in one line, then do the job.

Hi [Name],

I am sorry that invoice [number] for [amount] is overdue, and I should have replied to your earlier reminders.

I can pay [amount] on [date]. [If partial: and the rest by date]. I will send confirmation each time.

Please tell me if you need anything else, including any late fee you apply under our agreement.

Mistakes to avoid

• Ignoring the reminder and hoping it goes away. The next notice is usually firmer.
• Promising a payment date you cannot meet. A second miss does more harm than the first.
• Saying "I already paid" without a date, method, or reference to check.
• Blaming their invoicing system before you have checked your own records.

Questions people ask

Do I have to pay a late fee?

Only if your contract or the invoice terms said so. Check them. If you think the fee is unfair, you can ask politely whether they will waive it, especially when you pay promptly. Do not assume it will be waived, and ask a professional if the amount is large.

What if I disagree with the invoice?

Say so right away in writing, and be specific about which line or amount you dispute. Offer to pay the part you agree with. Do not stay silent while the invoice ages. Check your contract for how disputes are handled.
