To send an unpaid bill to collections responsibly, verify the balance and supporting records, give the customer a clear chance to resolve an error or dispute, and make a documented placement with an appropriate collection agency. The timing and wording should follow the agreement, the type of account, applicable law, and a process that treats the customer fairly; a generic day-count is not a substitute for that review.

Start by identifying the account and the proposed action

A past-due invoice is not automatically ready for a third-party referral. First, distinguish between a business invoice and an obligation incurred primarily for personal, family, or household purposes. Under the Fair Debt Collection Practices Act (FDCPA) definitions, the federal term debt is limited to the latter type of consumer obligation. The same statute defines a creditor and a debt collector separately, with stated exclusions. Those definitions matter when deciding which protections, disclosures, and vendor controls may apply.

Also identify whether the intended arrangement is a collection placement or a sale or assignment of the receivable. A placement agreement should state who owns the account, who may communicate with the customer, how funds are remitted, what fees apply, and when the account may be returned. Do not assume that a referral automatically changes ownership or that a third party may take any step the original creditor could take.

Confirm the receivable before escalating it

Review the account as though someone unfamiliar with it will need to understand the file. Escalation should pause if the balance cannot be substantiated, the customer has raised a credible dispute, or account notes indicate a promised correction, credit, payment plan, bankruptcy issue, or other unresolved question.

  • Confirm the customer identity, billing address, account number, invoice number, invoice date, due date, and current balance.
  • Compare the amount with the contract, purchase order, service record, delivery confirmation, credit memo, returns, and payments received.
  • Review the payment terms, any contractual notice or dispute procedure, and whether interest, late fees, collection costs, or attorney fees are actually authorized.
  • Record the issue date, each reminder, the customer's response, and the internal decision to escalate.

For a broader view of how overdue invoices fit into receivables operations, see the related article on the accounts receivable collection period. A measured process is more useful than treating every late invoice as the same kind of problem.

Use a clear internal escalation record

Before using an outside agency, establish a repeatable process for reminders and account review. The exact cadence should reflect the business relationship, the written terms, the nature of the invoice, and any applicable requirements. The goal is not to create pressure for its own sake; it is to make the amount, the path to resolution, and the consequences of continued nonpayment understandable.

  1. Send a routine reminder. State the invoice reference, amount due, due date, and payment options. Give the customer an easy way to report a billing error.
  2. Investigate before repeating a demand. Check whether a payment, return, service complaint, or address problem explains the delinquency. Correct the record when warranted.
  3. Issue a final written notice when appropriate. Identify the amount being requested, the invoice or agreement, a reasonable response date consistent with the account terms, and a contact for questions or disputes. Keep a copy and record how it was delivered.
  4. Make an intentional referral decision. Confirm that a manager or authorized owner has reviewed the file and approved the agency placement.

Certified mail is not a universal federal prerequisite to referring an invoice, and a final notice should not make threats that are inaccurate or not authorized by the agreement and applicable law. In particular, do not state that litigation, credit reporting, fees, or other action will occur unless the statement is truthful, permitted, and appropriate for the account.

Prepare a focused placement file

A collection agency can work more accurately when it receives a coherent file rather than fragments of correspondence. Transfer information through the security method agreed with the agency and limit the file to what is needed for the assignment. Maintain the original records and a copy of what was sent.

  • The governing agreement, purchase order, or other basis for the charge, if applicable.
  • The invoice or statement, plus a clear calculation of the current balance.
  • Relevant proof of delivery, performance, acceptance, returns, credits, and payment history.
  • Current contact details and a factual log of prior communications and reported disputes.
  • Instructions about account status, settlement authority, documents that must not be shared, and the contact person for questions.

Good documentation also supports internal control. The related article on receivables reconciliation and revenue assurance discusses why records should be reconciled before they are relied on for a collection decision.

Select and supervise the collection agency

Choose an agency whose experience fits the account type and jurisdiction. As part of vendor due diligence, ask how the agency handles licensing or registration where relevant, complaints, disputes, communications, information security, reporting, remittances, and account return or closure. Review the referral agreement carefully; it should allocate responsibilities rather than assume that compliance is someone else's responsibility.

Consumer accounts require particular care. Regulation F implements federal rules for FDCPA debt collectors. For a covered debt collector, the CFPB's current validation-notice rule generally requires specified validation information either in the initial communication, within five days after that initial communication, or orally in that communication, subject to the regulation's terms and exceptions. The rule specifies required information and related disclosures; it is not a template for a creditor to apply indiscriminately to every commercial invoice.

Federal rules do not eliminate all state requirements. The Regulation F provision on state laws explains that state protections are not displaced unless inconsistent, and greater consumer protections are not treated as inconsistent. State licensing, notice, limitation-period, interest, fee, privacy, and collection-practice questions can therefore require jurisdiction-specific review.

After placement, keep roles and records clear

Once the file is placed, coordinate with the agency so the customer is not given conflicting information. Update internal notes, route account-specific inquiries to the appropriate contact, and establish how the agency will report payments, disputes, recalls, and closure. Reconcile receipts to the agency's reporting and preserve the placement agreement, reports, and remittance records.

Continue to review the account. A new dispute, a payment made directly to the creditor, an insolvency notice, or new information about the balance should be communicated promptly through the established process. If the circumstances change, reassess the placement rather than allowing an outdated file to drive further contact.

When legal or compliance review is appropriate

Obtain advice from qualified counsel or a compliance professional before escalating a file that involves a consumer account, a disputed balance, a deceased customer, bankruptcy or insolvency, a possible lawsuit, credit reporting, a cross-border party, government or healthcare-related obligations, or uncertain state-law requirements. This article is general operational information, not legal advice, and it does not determine whether a particular balance is collectible.

Frequently asked questions

What does accounts receivable collection mean?

Accounts receivable collection is the work of tracking amounts customers owe, following up on overdue invoices, resolving valid billing issues, and receiving payment. Referring an account to a collection agency is one possible later-stage step, not the entire accounts receivable process.

Is collections part of accounts receivable?

Yes. Collections is commonly part of accounts receivable management because it addresses invoices that remain unpaid after normal billing and follow-up. It should remain connected to accurate billing records, dispute handling, payment posting, and fair customer communication.
