B2B debt collection software: B2B collection software that works unpaid invoices without a collection agency

No, as a general rule. The Fair Debt Collection Practices Act defines a "debt" as an obligation of a consumer arising out of a transaction that is primarily for personal, family, or household purposes (15 U.S.C. 1692a(5)). An invoice one company owes another for goods or services does not meet that definition, so the FDCPA, and the CFPB's Regulation F rules built on top of it, generally do not govern a pure business-to-business collection.

The FDIC's Consumer Compliance Examination Manual states it about as plainly as a regulator ever states anything:

"The FDCPA and Regulation F apply only to the collection of debt incurred by a consumer primarily for personal, family or household purposes. They do not apply to the collection of corporate debt or to debt owed for business or agricultural purposes."

That surprises people, so be precise about what it does and does not mean. It does not mean commercial collections is a free-for-all. Several things still bind you:

• The TCPA governs how you may call and text, and its restriction on autodialed and prerecorded calls to cell numbers (47 U.S.C. 227(b)(1)(A)(iii)) contains no personal-or-household limitation. Dialing a business contact's mobile with an autodialer is a TCPA question whoever owes the money.
• State law. Several states regulate collection conduct more broadly than the FDCPA does, and most require a license or bond to collect on someone else's behalf. Collecting your own debt, which is what DebtAgent does, sits in a much simpler position than third-party collection.
• California changed the map on July 1, 2025. Senate Bill 1286 extended the state's Rosenthal Act to certain "covered commercial debt." Read the text carefully before you panic or relax: it reaches debt owed by a natural person to a lender, commercial financing provider, or debt buyer, where the debtor's total commercial credit with that party is $500,000 or less, on transactions entered into, renewed, sold, or assigned on or after July 1, 2025. On its face that targets commercial lending and debt buying, not an ordinary supplier chasing its own trade invoices, and California has since confirmed it: AB 1521 amended Civil Code 1788.2 effective January 1, 2026 to define trade credit and exclude it from covered commercial debt. If you finance your customers rather than supply them, get advice. The wider federal and state picture is set out in our guide to commercial debt collection laws.
• Fraud, defamation, and unfair-practices law apply to everyone. You cannot threaten what you will not do, misstate the amount, or report the debt in a way you cannot support.
• A personal guarantee changes the analysis. If an owner personally guaranteed the debt and you pursue them as an individual, you can walk straight back into consumer-debt territory. This is the most common way a B2B collection quietly becomes an FDCPA problem.

DebtAgent applies the strict standard everywhere by default: no threats, no harassment, contact windows respected, frequency capped, disputes honored. Not because a B2B invoice always requires it, but because the cheap version of collections, the version that yells, is exactly the version that loses you the customer and creates the legal risk. This page is information, not legal advice; if a specific account is heading toward litigation, ask a lawyer.

Late payment is not an edge case in American B2B trade, it is the median experience. The figures below come from published 2025 research and are worth knowing before you decide how much process this deserves.

Read the first and third rows together and the strategy writes itself. Nearly half your overdue value is sitting with customers who intend to pay and are managing their own cash, which means the vendor who follows up consistently gets paid first. Not the one who follows up loudest.

Companies come to collections software convinced they have a deadbeat problem. Usually they have a process problem. In our reading of how these accounts play out, an overdue commercial invoice tends to fall into one of four buckets, and only one of them is a genuine refusal to pay:

The invoice never reached the right person

It went to the person who signed the contract, not to accounts payable. Nobody is refusing anything, the invoice is sitting in an inbox that does not process invoices. The fix is a follow-up that asks a specific question: who should this go to in AP?

It is stuck in an approval queue

Your invoice needs a PO number it does not have, or a manager's signature, and the AP clerk has silently parked it. The fix is a message that asks what is blocking approval, not one that asks for payment again.

They are managing their own cash

They can pay, and they are paying the vendors who chase them. This is common and it is not personal. The only defense is being one of the vendors who chases, consistently and unemotionally, which is precisely the thing a busy AR person stops doing in month two.

They dispute the work

They are unhappy with what you delivered and the invoice is the only lever they have. A collections sequence is the wrong tool here, and DebtAgent will stop the cadence the moment a dispute comes back, so you can go have a conversation instead of firing another demand into it.

Three of those four are solved by disciplined, polite, relentless follow-up. That is the entire thesis of this product. For the escalation ladder that handles the fourth, our playbook on how to collect a debt from a business that won't pay works through it rung by rung.

An agency is a real tool with a real place, and it would be dishonest to pretend software replaces it in every case. Hand the account to a commercial collection agency when:

• The debt is old, past roughly six months of silence, and your own follow-up has produced nothing.
• The debtor has gone dark: no reply on any channel, mail returned, phone disconnected. Finding people is skip tracing, and that is an agency skill, not a software feature.
• You have written off the relationship and are optimizing purely for recovery.
• The amount justifies the fee. Handing over a $900 invoice to lose a third of it rarely makes sense; a $90,000 one is a different calculation.

What you should not do is send the account to an agency at day 45 because nobody in-house had time to send the third reminder. That is paying a contingency fee for a task that costs you nothing but consistency, on an invoice that had not even stopped being collectible yet. Use software for the first 90 days, when most of the money is still recoverable and the relationship is still intact, and reserve the agency for what is genuinely left.

If it does come to that, the export matters. Every touch DebtAgent sends is logged with a timestamp, so you hand the agency or your attorney a dated contact history instead of a shrug and a folder of forwarded emails.

Nobody wakes up wanting to chase invoices. In a company under about 50 people, collections is a side duty bolted onto a controller, an office manager, or the founder, and it competes with work that feels more urgent and much less uncomfortable. Three failures follow, and they are the same three every time:

It stops at reminder two. The first nudge is easy, the second is fine, and the third one, the one with an edge in it, requires a decision about how firm to be with a customer. So it does not get sent. Most of what an agency recovers, it recovers at steps three through six.

The wording gets worse under pressure. The email written by an annoyed founder at 11pm on day 75 is the one that costs the relationship, and occasionally the one that creates a legal problem. A pre-drafted escalation ladder never writes that email.

Nothing is written down. When the account eventually needs a decision, nobody can say what was sent, when, or what the debtor promised. The file has to be reconstructed from three inboxes.

Automation fixes all three by removing the moment of hesitation. The step is scheduled, the copy is already written, the send is logged. Your AR person's job stops being "find the courage to chase" and becomes "handle the replies," which is the part a human is actually good at.

A cadence is just a schedule of what you say and when. The shape below is a reasonable default for a 30-day-net commercial invoice, and it is roughly what DebtAgent generates if you accept the defaults. Adjust the spacing for your industry: construction and staffing run longer, agencies and SaaS run shorter.

• Day 3 before due: a courtesy heads-up. Not a chase. It confirms the invoice arrived and gives AP a chance to flag a missing PO before it is late.
• Day 1 overdue: short, friendly, assumes an oversight. Restate the invoice number, amount, and payment link.
• Day 7: ask a question rather than repeat a demand. "Is this invoice waiting on an approval, or is there something I need to fix?" Replies to this are what unblock most accounts.
• Day 15: escalate the recipient, not the volume. Copy in the AP manager or the person who signed the contract.
• Day 30: firm. State the amount, the days outstanding, and the consequence you are actually willing to follow through on, such as pausing further work or applying the late fee in your terms.
• Day 45 to 60: a final notice, plainly worded, stating what happens next and when. Only threaten what you will genuinely do.

Two rules make the difference between a cadence that collects and one that annoys. Every message must contain the invoice number, the amount, and a way to pay in one click, because the friction you are usually fighting is not refusal, it is effort. And every message must stop the moment they pay, dispute, or ask you to stop. Chasing a debtor who has already paid is the fastest way to turn an administrative problem into an angry one.

It is set by state law and usually runs three to ten years from the date payment was due, with four to six years being the most common range for a written contract. If you sold goods rather than services, Article 2 of the Uniform Commercial Code sets a four-year period in almost every state, and it generally overrides the longer general contract limit.

The number that should actually drive your process is much smaller. A B2B invoice is economically dead long before it is legally dead: recovery odds fall sharply as an account ages, which is exactly why collection agencies quote a higher contingency rate on older paper. By the time a limitation date is in play, the person who signed off on the work has usually left and the paper trail has gone cold.

Two rules are worth knowing because they change the date. The clock normally starts the day after payment was due, not the invoice date, and on an open account many states run it from the last transaction or last payment instead. And in most states a partial payment or a signed payment agreement restarts the full period, which is a genuine reason to always paper a payment plan. The full state-by-state breakdown is in our guide to the statute of limitations on unpaid invoices. This is information, not legal advice.

Open with your name, the invoice number, the amount and the days past due, ask one closed question, then stop talking. The silence after you name the number is where you learn the real reason the invoice has not been paid, and it is always one of three things: a process problem, a dispute, or a cash problem. Each one needs a different second half of the call.

Close by getting a specific dollar amount on a specific date, never "next week", and send a confirmation email inside the hour with the invoice attached. A commitment you did not write down is a commitment you cannot follow up on, and "when we spoke on the 12th you confirmed" is the most useful sentence in B2B collections.

One call per stage is enough: around day 20, day 35, day 60 and day 95, with the email sequence carrying the work in between. Calling the same AP contact three times in a week does not move an invoice stuck in an approval queue, it just makes you easy to screen. We have the word-for-word wording for all of it, including the broken promise, the disputed invoice and the last call before placement, in our collection call script examples.

Most of that ladder now runs unattended through AI debt collection software, so the calls you personally make are the ones that actually need a human.

Yes, and it is a distinct middle option most B2B sellers never price. Between doing the chasing yourself and placing an account with a contingency agency sits accounts receivable outsourcing: an outside firm works your whole book from the invoice date, writes to your customers in your company's name, and bills a flat monthly retainer rather than a share of what it recovers. US providers commonly quote $500 to $7,000 a month, set by how many customers carry an open balance.

Because those communications go out as you, the arrangement stays first-party, which matters for the same reason the FDCPA analysis above matters. Nothing is assigned, you remain the creditor of record, and the customer relationship stays yours. The catch is that almost no AR outsourcing firm is a licensed collection agency, and almost none will litigate, so genuinely delinquent commercial accounts still come back to you at around day 120 with a recommendation attached.

Treat it as a capacity purchase, not a recovery purchase. It is the right buy when the volume of follow-up genuinely exceeds what your team can work, and the wrong buy when the follow-up simply is not scheduled. The second problem costs a great deal less to fix.

B2B collection software should do the work an agency would charge you 20% to 25% for, during the window when the invoice is still cheap to collect. That means a scheduled escalation across email, SMS and voice from day 3 past due through day 60, a contact log that stands up if the claim goes further, and a hard stop the moment payment posts.

The test is coverage of the late window rather than features at the front. Almost every tool sends a polite day-3 email; the useful ones are still working the account at day 45, which is where automated B2B debt collection software earns its cost. If your accounting package is doing the chasing today, note that QuickBooks stops after three reminders and Xero after five, and that dedicated payment reminder software exists specifically to cover what comes after. On pricing, the shapes to compare are flat monthly, per open invoice and per seat, which is worked through in the B2B payment reminder software comparison.
