Partial payment acceptance letter — accept what was paid while protecting the balance

Cashing a check marked 'payment in full' when you are owed more can legally extinguish the remaining balance under the UCC's accord and satisfaction doctrine. This letter documents that you accepted the partial payment without waiving your right to the remainder.

Use it for

  • Service businesses that received a payment less than the full invoice amount
  • Situations where the customer sent a check marked 'paid in full' or 'final payment'
  • Any partial payment scenario where you want to preserve your right to collect the balance
  • Formalizing a partial payment while setting a deadline for the remainder

Do not use for

  • Situations where you and the client have agreed that the partial payment settles the full balance — use a settlement agreement instead
  • Partial payments made under a prior written payment plan agreement — that agreement already governs

Re: Acknowledgment of Partial Payment — Invoice(s) {{INVOICE_NUMBERS}}

Dear {{CLIENT_NAME}},

This letter acknowledges receipt of ${{PARTIAL_PAYMENT_AMOUNT}} on {{PAYMENT_DATE}} toward Invoice(s) {{INVOICE_NUMBERS}}, which reflect services totaling ${{ORIGINAL_INVOICE_AMOUNT}}.

IMPORTANT NOTICE: This payment is accepted as a partial payment only. It does not constitute full satisfaction or settlement of the amounts owed under the referenced invoice(s). {{YOUR_BUSINESS_NAME}} expressly reserves its right to collect the remaining balance.

[If the check or payment was marked "payment in full," "paid in full," "final payment," or similar: The above payment was received notwithstanding any notation on the check or accompanying communication suggesting it constitutes full and final payment. {{YOUR_BUSINESS_NAME}} does not accept such a designation. The partial payment has been applied to reduce the outstanding balance; the remaining amount is still due and payable in full.]

REMAINING BALANCE

  Original invoice total:    ${{ORIGINAL_INVOICE_AMOUNT}}
  Payment received:         (${{PARTIAL_PAYMENT_AMOUNT}})
  Remaining balance due:     ${{REMAINING_BALANCE}}
  Due date for remainder:    {{BALANCE_DUE_DATE}}

Please arrange payment of the remaining balance of ${{REMAINING_BALANCE}} by {{BALANCE_DUE_DATE}}. If you anticipate difficulty paying by that date, please contact us immediately to discuss a payment arrangement before that deadline.

Sincerely,

{{YOUR_NAME_TITLE}}
{{YOUR_BUSINESS_NAME}}
{{CONTACT_EMAIL_PHONE}}
