A Notice of Payment 60 Days Past Due is a formal collections letter sent by a creditor to a customer whose invoice has gone unpaid for two full billing cycles past the original due date. It escalates beyond the initial 30-day reminder by restating the outstanding balance with all accrued late fees, setting a firm final payment deadline, and explicitly warning of next-step consequences β including referral to a collections agency, service suspension, or credit reporting. Unlike a casual follow-up email, this letter creates a documented paper trail that supports further legal or collections action if the customer continues to ignore the debt.
An unpaid invoice at 60 days is no longer a billing oversight β it is a collections problem, and treating it as anything less costs you money twice: once in the lost cash flow and again when recovery becomes harder the longer you wait. Collection rates drop sharply after 90 days, and without a documented escalation sequence β 30-day notice, 60-day formal letter, 90-day final demand β collections agencies and small claims courts both expect to see evidence that you made systematic, written attempts to collect before escalating. Sending this letter by email and certified mail creates exactly that record. It also signals to the customer that your payment terms are enforced, which deters repeat delinquency across your entire client base. This template gives you a professional, specific letter ready to send in under 10 minutes β with every clause your collections sequence requires already in place.

Why it matters: Phrases like 'we understand you may have overlooked this' signal low urgency and invite further delay at a stage where the account is already two months delinquent.
Fix: Open directly with the account status: the invoice number, the amount, and the number of days past due. State clearly that this is a second and final notice.
Why it matters: Collecting only the original invoice amount forfeits fees you are contractually owed and signals that your late-fee policy is not enforced.
Fix: Calculate fees at the rate stated in your contract or original invoice and display the itemized breakdown β original amount, fee month 1, fee month 2, total due.
Why it matters: Without a fixed calendar date, the customer has no actionable trigger, and you have no clean basis for escalating to collections or filing a claim.
Fix: State a deadline of 7 to 10 business days from the letter date and repeat it in both the deadline clause and the consequences clause.
Why it matters: If you threaten collections referral at 60 days and then send another letter at 90 days without acting, the customer learns your warnings are empty and stops responding.
Fix: Only include consequences you will actually execute. If you plan to refer to collections at 90 days, say so β and follow through on schedule.
In plain language: Identifies your business and the customer's billing contact with full names, addresses, and the date the letter is sent.
[YOUR COMPANY NAME] | [ADDRESS] | [CITY, STATE ZIP] | [DATE] To: [CUSTOMER NAME / COMPANY] | Attn: [ACCOUNTS PAYABLE CONTACT] | [CUSTOMER ADDRESS]
Common mistake: Sending the letter to a general company email rather than the specific accounts-payable contact β it sits unread while the clock runs.
In plain language: States the purpose of the letter and cites the specific invoice number and original due date so there is no ambiguity about which debt is overdue.
Re: SECOND NOTICE β Invoice #[INVOICE NUMBER] Dated [INVOICE DATE] β Payment 60 Days Past Due
Common mistake: Omitting the invoice number in the subject line, forcing the recipient to search their records and creating an excuse for further delay.
In plain language: Clearly states that the account is now 60 days past due and that this is a formal second notice, distinguishing it from routine reminders.
Despite our previous notice dated [DATE OF 30-DAY NOTICE], we have not received payment for the above-referenced invoice. As of [CURRENT DATE], this balance is now 60 days past due.
Common mistake: Opening with an apology or overly soft language β phrases like 'we understand you may have overlooked' undercut urgency at a critical escalation point.
In plain language: Restates the original invoice amount, shows the late fees that have accrued, and gives the total amount now owed.
Original Invoice Amount: $[ORIGINAL AMOUNT] Late Fee (30 days): $[FEE MONTH 1] Late Fee (60 days): $[FEE MONTH 2] Total Amount Now Due: $[TOTAL]
Common mistake: Stating only the original invoice amount and ignoring accrued fees β this understates what is owed and may require a corrected letter later.
In plain language: Sets a specific calendar date by which full payment must be received to avoid the stated consequences.
Full payment of $[TOTAL AMOUNT DUE] must be received by [DEADLINE DATE β e.g., 10 business days from letter date]. Payment after this date will not prevent the actions described below.
Common mistake: Setting a vague deadline like 'within a reasonable time' or 'as soon as possible' β a specific date is essential for any subsequent legal or collections action.
In plain language: Explicitly states what actions the sender will take if payment is not received by the deadline β collections referral, service suspension, credit reporting, or legal proceedings.
If full payment is not received by [DEADLINE DATE], we reserve the right to (a) refer this account to a third-party collections agency, (b) suspend all services to your account, and (c) report this delinquency to commercial credit bureaus.
Common mistake: Threatening consequences you are not actually prepared to follow through on β empty threats undermine credibility and future enforcement.
In plain language: Provides clear, complete instructions for how the customer can pay immediately β bank transfer details, online payment link, check payable-to, or phone number for card payment.
To resolve this balance immediately, please remit payment via: Bank Transfer: [BANK NAME] | Account: [ACCOUNT NUMBER] | Routing: [ROUTING NUMBER] Online: [PAYMENT PORTAL URL] Check payable to: [COMPANY NAME] β please note Invoice #[INVOICE NUMBER] on the check.
Common mistake: Omitting payment instructions entirely and expecting the customer to look up prior correspondence β every friction point adds days to your collection time.
In plain language: Gives the customer a named point of contact to call or email if they wish to dispute the charge or negotiate a payment plan, keeping the door open while maintaining firmness.
If you believe this notice has been sent in error, or if you wish to discuss a payment arrangement, please contact [CONTACT NAME] at [PHONE NUMBER] or [EMAIL ADDRESS] before [DEADLINE DATE].
Common mistake: Providing no contact option β customers with legitimate disputes or cash-flow issues will simply ignore the letter rather than proactively reach out.
In plain language: Closes the letter formally, states the sender's name and title, and includes a signature line to give the letter authority.
We value our relationship with your business and hope to resolve this matter promptly. Sincerely, [SENDER NAME] [TITLE] [COMPANY NAME] [PHONE] | [EMAIL]
Common mistake: Closing with overly conciliatory language that contradicts the urgency of the notice β keep the tone professional and firm, not apologetic.
Fill in your full legal business name, address, phone, and email in the sender header block. Enter today's date as the letter date.
π‘ Use the same company name that appears on the original invoice to avoid any confusion about the sending entity.
Enter the customer's legal entity name, billing address, and the name of their accounts-payable contact. If you have a PO number or account number on file, include it in the subject line.
π‘ Call ahead to confirm the current AP contact before sending β personnel changes are a common reason overdue letters go unanswered.
Insert the invoice number, original invoice date, original due date, and the date your 30-day notice was sent. This creates a clear paper trail showing escalation.
π‘ Attach a copy of the original invoice and the prior 30-day notice to the letter so the recipient has everything in one communication.
Start with the original invoice amount, add the late fee for the first 30-day period, add the fee for the second 30-day period, and display the running total clearly.
π‘ Reference your original contract or invoice for the agreed late-fee rate β typically 1.5% per month. If no rate was agreed, check the statutory rate in your jurisdiction.
Pick a concrete calendar date β typically 7 to 10 business days from the letter date β and enter it in both the deadline clause and the consequences clause.
π‘ Send the letter by both email and certified mail with return receipt. The certified mail timestamp is evidence of delivery if you later need it in court or collections.
Check each consequence listed β collections referral, service suspension, credit reporting β and remove any you are not actually prepared to act on. Only include credible threats.
π‘ If you intend to suspend services, verify your contract gives you that right at 60 days and that doing so does not expose you to a breach-of-contract claim.
Have the letter signed by the owner, controller, or AR manager β not a junior staff member. Send on the same day you set as the letter date.
π‘ Log the send date, method, and recipient in your AR aging report so you have a documented timeline if the account proceeds to collections or litigation.
A 60-day past due notice is a formal collections letter sent to a customer whose invoice remains unpaid 60 days after the original due date. It escalates from the initial 30-day reminder by restating the balance with accrued late fees, setting a firm final payment deadline, and warning of specific consequences β such as collections referral or service suspension β if payment is not received.
Send it on or shortly after the 60th calendar day past the invoice due date, provided a 30-day notice was already sent and went unanswered. Waiting longer reduces the chance of recovery β collection rates drop significantly after 90 days of non-payment. Prompt escalation also demonstrates that your terms are enforced, which discourages repeat delinquency.
Yes, provided your original invoice or contract stated a late-fee rate. A common rate is 1.5% per month on the outstanding balance. If no rate was agreed in advance, you may be limited to the statutory interest rate in your jurisdiction. Always display the fee calculation as a clear itemized breakdown in the letter rather than adding a lump sum without explanation.
Include only consequences you are prepared and contractually permitted to enforce. Common options are: referral to a third-party collections agency, suspension of services or credit terms, reporting the delinquency to commercial credit bureaus, and initiation of legal proceedings. Threatening all four when you plan to act on only one undermines your credibility if the matter reaches court.
Send it by both. Email creates an immediate timestamped record; certified mail with return receipt creates proof of delivery that is accepted as evidence in court and by collections agencies. If the account proceeds to a small claims filing or commercial collections, documented delivery at each stage β 30 days, 60 days, final demand β significantly strengthens your position.
A 60-day past due notice is a collections escalation letter that still invites the customer to pay or contact you to resolve the matter. A demand letter is a final formal ultimatum β typically sent at 90 days or later β that states legal action will be filed by a specific date if payment is not received. The 60-day notice is the second step in a structured collections sequence; the demand letter is the last step before you file.
Most businesses follow a three-notice sequence: a 30-day reminder, a 60-day formal notice, and a 90-day final demand letter. After the final demand goes unanswered, referral to a collections agency or filing in small claims court is appropriate. Sending more than three notices without escalating signals that your terms are not enforced and encourages delinquent customers to delay indefinitely.
Yes, though the tone and legal considerations differ slightly. For consumer debtors (B2C), the Fair Debt Collection Practices Act (FDCPA) in the United States restricts certain collection practices β the FDCPA applies primarily to third-party collectors, but some states extend similar rules to original creditors. For commercial debtors (B2B), fewer consumer-protection restrictions apply and the letter can be more direct. When in doubt about B2C compliance, have the letter reviewed by a local attorney before sending.
The 30-day notice is the first formal reminder β it restates the original invoice and requests payment with a polite but firm tone. The 60-day notice is a direct escalation that adds accrued late fees and introduces specific consequences. Use the 30-day version first; switch to this template only after it goes unanswered.
The 90-day notice is a final demand that typically states legal action or collections filing is imminent. The 60-day notice still leaves the door open for the customer to resolve the matter directly. Sending a 90-day notice without the 60-day escalation in between weakens your documented collections sequence.
A demand letter is the last step before legal proceedings β it sets a hard deadline and states a specific legal remedy. The 60-day past due notice is a collections-sequence document that still invites resolution; the demand letter is a formal ultimatum. Use the demand letter only after the 60-day notice has been ignored.
If a customer responds to the 60-day notice but cannot pay in full, a payment plan agreement formalizes an installment schedule. The 60-day notice triggers the conversation; the payment plan agreement documents the resolution. Both documents together create a complete paper trail from delinquency to settlement.
Consulting and agency firms use 60-day notices to enforce Net 30 retainer terms before pausing active client engagements.
Contractors reference the overdue balance alongside potential mechanic's lien filing rights, which adds legal weight to the escalation.
Subscription businesses tie the notice directly to a service-suspension date, making the consequence immediate and operationally tangible for the customer.
Distributors include a credit-hold notice alongside the past due letter, cutting off future orders until the balance is cleared.
