1
Enter both parties' legal names and the account number
Use the seller's registered legal entity name and the customer's exact legal name as it appears in your accounting system. Include the customer's account number for unambiguous identification.
π‘ Cross-check the customer's legal name against their original credit application or the contract that established the account β mismatches create enforcement complications.
2
Document the prior credit terms
State the credit limit, payment period (e.g., Net 30), and the date the terms were originally established. This creates a clear baseline for the conversion.
π‘ Pull this information directly from your credit agreement or account setup records β paraphrasing from memory introduces errors that the customer may dispute.
3
State the reason for conversion factually
List specific unpaid invoices by number, date, and dollar amount, or reference the outstanding balance total. Avoid characterizations of intent β stick to amounts and dates.
π‘ A factual, dollar-specific reason is harder to dispute than a vague reference to 'unsatisfactory payment history.' Numbers close arguments.
4
Set a specific effective date
Choose a calendar date that gives the customer at least 3β5 business days' notice before COD takes effect. Record this date clearly in the body of the letter.
π‘ Do not backdate the effective date to a date before the notice is sent β this is unenforceable and creates bad faith exposure.
5
List the outstanding balance and a settlement deadline
Itemize open invoices by invoice number, date, and amount. Set a specific date by which the existing balance must be paid under the original terms.
π‘ Attaching a copy of the aging report or invoice list as an exhibit removes any ambiguity about what is owed and speeds up resolution.
6
Specify accepted COD payment methods
List every payment form you will accept on delivery β certified check, money order, ACH, or payment link β so your operations team and the customer's accounts payable team are aligned before the first COD shipment.
π‘ If you use a payment platform (e.g., Stripe, Bill.com), include the direct payment link so the customer can pay electronically before dispatch.
7
Have the customer's authorized representative sign
Send the notice with a signature block and request return of the signed copy within 5 business days. Keep the executed original in the customer's account file.
π‘ If the customer refuses to sign, send the notice by certified mail or tracked email and retain the delivery confirmation β this establishes receipt even without a signature.
8
Distribute to internal teams before the effective date
Send a copy of the executed notice to your order processing, warehouse, and AR teams so they can flag the account and enforce COD on the first order after the effective date.
π‘ Set a hard block in your order management system on the effective date so no COD-exempt order slips through by mistake.
