Frequently Asked Questions about Sample Letter to Client Requesting Payment

How do I politely ask a client for payment?

Always greet the client first, reference the exact invoice, and avoid accusatory language. Assume the payment was forgotten rather than ignored. Offer to help resolve any issues preventing payment.

When should I send the first payment reminder?

Send the first friendly reminder on the exact due date of the invoice. This is not confrontational, and serves as a helpful nudge for busy clients. Most clients appreciate this gentle prompt.

Should I call or email to request payment?

Always send a written request first via email. This creates a paper trail for your records. Only call if you receive no reply after two written follow ups.

What information must every payment request include?

Every request must state the invoice number, total amount, due date, and accepted payment methods. Attach a copy of the original invoice every time you follow up.
