When to Send an Invoice to Collections: A Timeline for Businesses

Every business that extends terms to other businesses eventually runs into an invoice that stops moving. Across the U.S., a past-due account can sit in accounts receivable for months while a company keeps sending statements and hoping. The hard part is knowing the point where "past due" turns into "not going to pay," and deciding when to send an invoice to collections instead of chasing it yourself. This guide lays out the warning signs and a stage-by-stage timeline built for commercial, business-to-business accounts.

What "Sending an Invoice to Collections" Means for B2B

Sending an invoice to collections means handing a past-due account to a third-party commercial collection agency that recovers the balance on your behalf. For business-to-business debt, this is a different world from consumer collections. Commercial collections deal with one company recovering money owed by another company, which runs on contract law, credit terms, and the leverage that exists between businesses. Consumer collections, by contrast, involve personal or household bills and a separate set of rules. The tools, timelines, and pressure points on a commercial account are not the same as the ones used on a personal debt, so if your business is owed money by another business, commercial collections is the lane you are in.

The Cost of Waiting to Send an Invoice to Collections

The longer an invoice sits unpaid, the harder it usually is to collect. Money gets reallocated, contacts leave, and businesses that are struggling tend to pay whoever applies the most pressure first. That is why aging is the single most useful signal for deciding when to send a past-due invoice to collections. Most companies track this through an accounts receivable aging report, grouping balances into current, 1 to 30 days late, 31 to 60, 61 to 90, and 90-plus. A high days sales outstanding number, or a growing pile in the net 90 column, is a sign your internal process has run its course. Waiting also chips away at your legal options, because statutes of limitations on unpaid debt vary by state and by the type of agreement, and once that window closes the ability to enforce the debt narrows sharply.

Warning Signs an Account Will Not Pay on Its Own

Some accounts self-correct with a reminder. Others send clear signals that a friendly follow-up will not work. Watch for these:

• Broken payment promises. The debtor keeps committing to a date and then missing it. One slip can be a cash-flow hiccup, but a pattern is a decision.
• Sudden silence. Calls, emails, and statements that used to get answered now go nowhere. When a paying relationship goes quiet, it usually means the money is being steered somewhere else.
• Disputes that surface only after the due date. If a customer never raises an issue until you ask to be paid, the "dispute" may be a stall tactic rather than a real problem with the work.
• Signs of financial trouble. Layoffs, closed locations, bounced payments, or new liens against the business all suggest the account is competing with a shrinking pool of cash.
• Partial payments that stall. A small "good faith" payment followed by nothing is often designed to keep you waiting rather than to settle the balance.
• Changed hands. The contact who owed you is gone, and no one new will take ownership of the balance.

When two or more of these show up on the same account, you are past the point where patience helps. That is usually the moment to send the invoice to collections.

Your Decision Timeline: From Past Due to Placement

There is no single legal deadline that tells you when to send an invoice to collections, but the aging of the account gives you a practical one. Here is a stage-by-stage view of what to do as a commercial invoice moves past due.

By the time an account crosses 90 days with no credible plan to pay, chasing it in-house tends to cost more in staff time than it recovers. For most B2B creditors, the 60 to 90 day window is when the decision to send the invoice to collections should be on the table, and 90-plus is when waiting starts working against you.

What to Have Ready Before You Place an Account

A collection agency works faster when the file is complete. Before you send an invoice to collections, pull together the documentation that proves the debt and supports enforcement:

• The signed contract, credit application, or purchase order
• Every unpaid invoice and a current statement of the balance
• Any personal guarantee on file
• The date of the most recent sale or payment
• Notes on your collection attempts and any promises the debtor made
• Whether the business is still operating

Having this ready does two things. It lets the agency validate the balance quickly, and it strengthens the case if the account eventually moves toward litigation. A clean, well-documented file is one of the biggest factors in how fast and how fully an account gets recovered.

How a Commercial Collection Agency Takes It From Here

Once an account is placed, the process is built to move. At Tucker Albin, recovery starts with a formal demand, followed by skip tracing and asset tracking to locate the debtor and confirm the ability to pay. Many accounts resolve through direct, professional negotiation, and where a valued relationship is worth protecting, a diplomatic mediation approach works to recover the balance while keeping the door open with the customer. When voluntary resolution fails and the balance justifies it, the account can be escalated to a nationwide network of collection attorneys for litigation.

Commercial recovery runs on a contingency basis, which means no fee unless the debt is collected, so the risk of placing an aged account is low. If you have an invoice that has stopped moving, our Commercial Debt Recovery team can tell you whether it is worth pursuing and how we would approach it.
