1
Enter both parties' details in the header
Add your company's full legal name, address, and the date at the top. Below, enter the customer's legal entity name, billing address, and the name of their accounts-payable contact if known.
π‘ Confirm the customer's legal entity name against the original supply agreement β using a trade name instead of the registered name can complicate enforcement.
2
Complete the subject line with account and invoice references
Fill in the account number (if your system assigns one) and list all relevant invoice numbers in the subject line so the letter can be matched to open items immediately.
π‘ If there are more than five invoices, list the oldest three and write 'and [X] additional invoices β see attached schedule' rather than cluttering the subject line.
3
State the suspension date clearly in the opening paragraph
Enter the effective date of the delivery hold β typically the date the letter is sent β and the total outstanding amount. Keep the opening to two sentences maximum.
π‘ Use the same date format throughout the entire letter to avoid any confusion about timelines.
4
List each overdue invoice with dates and amounts
Enter every overdue invoice number, its issue date, its original due date, the amount, and how many days past due it is. Add a clear total at the bottom of the list.
π‘ Pull this data directly from your accounts-receivable system and double-check every figure β a single arithmetic error gives the customer grounds to dispute the whole notice.
5
Document prior contact attempts
Note the dates and methods of previous reminders β email, phone, or written notice β and the name of any contact at the customer who was reached.
π‘ Keep copies of all prior reminders in a single file so they can be produced immediately if the matter escalates to collections or legal proceedings.
6
Set a firm reinstatement deadline and conditions
Specify the exact date by which full payment or a confirmed payment plan is required, and state clearly what qualifies as acceptable β wire transfer, cheque, or a signed installment agreement.
π‘ A 7β10 business day deadline is standard; shorter deadlines signal urgency without appearing unreasonable to a court or mediator.
7
Add the named contact and escalation consequence
Enter the name, direct phone, and email of the person the customer should contact, and state the consequence of non-response β typically referral to a collections agency or legal counsel.
π‘ The threat of collections referral prompts faster response than a vague mention of 'further action' β be specific.
8
Review, sign, and send via tracked method
Have the letter reviewed by the accounts-receivable manager or owner before sending. Send by email with read receipt and, for large balances, by registered mail as well.
π‘ Bcc your own file address and save the email send confirmation β delivery proof is critical if the customer later claims they never received the notice.
