Payment promise follow-up letter â€” when a customer promised to pay and didn't

When a customer makes a verbal or written promise to pay by a specific date and then misses it, a written follow-up letter documents the broken promise and escalates the seriousness of the situation without burning the relationship unnecessarily. This letter references the previous commitment, expresses disappointment without aggression, and sets a new firm deadline.

Use it for

Following up after a payment plan installment was missed.
Collecting after a customer said 'I'll pay by Friday' (or any specific date) and didn't.
Creating a written record of the broken commitment before escalating to legal or collections.
Any situation where you want to be firm without immediately jumping to a demand letter.

Do not use for

First contact on an overdue invoice â€” use a standard payment reminder first.
Active disputes where the customer contests the amount owed.

Re: Invoice #{{INVOICE_NUMBER}} â€” Missed Payment Commitment

Dear {{CLIENT_NAME}},

I am writing to follow up on Invoice #{{INVOICE_NUMBER}} for {{INVOICE_AMOUNT}}.

As you may recall, {{HOW_COMMITMENT_WAS_MADE}}, you indicated that payment would be made by {{PROMISED_DATE}}. That date has now passed without payment being received.

I understand that unexpected circumstances can interfere with payment plans, and I want to give you the opportunity to address this before taking further steps. However, this invoice has now been outstanding for an extended period, and I need to bring it to resolution.

Please arrange payment in full by {{NEW_DEADLINE}}.

You can pay online here: {{PAYMENT_LINK}}

Alternatively, please contact me at {{YOUR_PHONE}} or {{YOUR_EMAIL}} by {{NEW_DEADLINE}} to discuss an alternative arrangement if full payment is not possible at this time.

If I do not hear from you or receive payment by {{NEW_DEADLINE}}, I will have no choice but to proceed with further collection measures, which may include referral to a collections agency or filing a claim in small claims court.

I would prefer to resolve this directly with you. Please reach out.

Sincerely,
{{YOUR_NAME}}
{{YOUR_BUSINESS_NAME}}
{{YOUR_PHONE}}
{{YOUR_EMAIL}}
