B2B Collections Software: Credit and Collections Software for Overdue Business Invoices

B2B collections software is a platform that runs the accounts receivable collections process on business-to-business invoices: it sends the reminder and escalation sequence, tracks what has been promised and what has been paid, flags disputes, and keeps an auditable record of every contact. You stay the creditor. Nothing is placed with a third party and nobody takes a percentage.

The category goes by several names that mean roughly the same thing. Vendors sell it as accounts receivable collections software, AR collections software, credit and collections software, or collections automation software. The functional core is identical: take the open items on your aging report and apply a consistent, dated follow-up sequence to all of them rather than to whichever ones someone remembers.

What separates a real collections platform from a generic invoicing tool with a reminder checkbox is escalation and evidence. An invoicing tool sends the same polite nudge on a loop. A collections platform changes what it says as the balance ages, stops when a customer disputes, records the trail, and hands you a file you could actually give to a lawyer.

Four things change, and they change the product enough that consumer tools fit B2B badly.

Balance size and terms. A consumer account might be $400 due on receipt. A B2B invoice is often $5,000 to $250,000 on net 30, net 60 or net 90, sometimes against a master agreement with its own payment mechanics. The sequence has to be built around a contractual due date, not a statement cycle.

Why it is late. Consumer delinquency is usually about ability to pay. B2B lateness is usually about process: the invoice went to the wrong address, the PO number does not match, one line is disputed, or the approver is out. Software that only knows how to ask more firmly will never resolve any of those.

The relationship. Your overdue customer is often still an active customer who will order again next month. A tool that treats them like a defaulted account will cost you more in lost revenue than the invoice is worth.

The law. The FDCPA covers debt incurred primarily for personal, family or household purposes, so a genuine business-to-business invoice sits outside it. Consumer collections software is built around Regulation F call caps and disclosure requirements that do not apply to your commercial accounts, which makes it both heavier and worse-fitting than it needs to be.

Published US prices in August 2026 run from about $49 per month at the entry end to roughly $1,200 per month for a full mid-market platform, and there are three distinct pricing models underneath those numbers.

Per organization, flat. One subscription covers the company and adding people costs nothing. DebtAgent at $49, $149 and $499 per month and Paidnice at $69 per month work this way. This is the cheapest model for a team of more than three or four, and the only one where growing your AR headcount does not raise your software bill.

Per user, per month. BILL charges $49, $65 or $89 per seat. Fine at two seats, expensive at ten, and it quietly discourages you from giving read access to the salespeople who actually know why an account is disputed.

Volume or revenue tiered. Paidnice's Pro tier ladders from $99 per month at 300 invoices to $799 at 4,000. Gaviti is usage based and does not publish a rate. Upflow segments by company revenue and quotes.

Then there is the model that is not software at all. A collection agency charges 25% to 50% of what it recovers, usually with a minimum balance of $500 to $1,000 before it will take a file. On a single $20,000 invoice at a 25% rate that is $5,000, which is more than most of these platforms cost for a year.

Every software platform in the table above charges a fixed subscription rather than a contingency fee. DebtAgent, Chaser, BILL, Paidnice, Gaviti, Upflow and Simplicity Collect all bill on a subscription: flat per organization, per seat, or tiered by volume. None of them takes a percentage of what you collect. Contingency pricing is a collection agency model, not a software model.

That distinction is worth more than it sounds. Under contingency, the more successful your collections are, the more you pay, and your incentive to work an account early conflicts with the agency's incentive to work it at all. Under a subscription, the marginal cost of recovering the next invoice is zero, so there is no balance too small to chase and no reason to let a $1,200 item age out because it is under an agency's minimum.

The practical rule: use fixed-price software for everything under about six months past due and in your own name, and reserve contingency for the accounts that are genuinely old, disputed beyond repair, or where the debtor has disappeared and someone needs to go find them.

Mostly no, and vendors use the labels interchangeably. There are two real distinctions hiding under the names, and both matter when you shortlist.

Credit and collections tools sometimes include credit control on the front end. That means credit application workflows, credit limits, and holding new orders when an account goes past due. If you extend terms to new customers regularly, that front half is worth having. If your customer list is stable, it is a feature you will never open.

Collections automation sometimes means only reminders. Plenty of products marketed as collections automation software send scheduled emails and stop there. Ask specifically what happens at day 60 and day 90: whether the tone changes, whether a statement of account goes out, whether a formal notice is generated, and what record you are left with. If the answer is another reminder, it is an invoicing feature wearing a collections name.

The third label to watch out for is collection agency software. Products like Simplicity Collect and CogentCollect are built for agencies collecting on behalf of other people: client trust accounting, commission splits, placement queues, skip tracing. They are excellent at that and a poor fit if you are collecting your own receivables, because half the product exists to manage a client relationship you do not have.

If the phrase you actually searched was accounts receivable collections software, that is the same job described from the AR side, and it has its own page: accounts receivable collections software.

A working setup for overdue B2B contracts has four parts, and most companies already own two of them.

1. The system of record. QuickBooks, Xero, NetSuite or Sage holds the invoice, the terms and the payment. This is where the aging report lives and it stays the source of truth.
2. The collections layer. B2B collections software reads the open items and runs the escalation sequence, in your name, with a dated record of each touch.
3. A payment path in the message itself. Every reminder should carry a way to pay right then. Removing the step where the customer has to find your remit-to details closes more invoices than any wording change.
4. An escalation route. A demand letter template, a small claims threshold you have decided in advance, and a relationship with a commercial agency for the genuinely dead accounts.

What you generally do not need is a separate contract management platform bolted on. The obligation you are enforcing is the invoice and the terms behind it. Tracking contract renewal dates is a different job and mixing the two usually produces a system nobody updates.

Generally no. The FDCPA defines a debt as an obligation incurred primarily for personal, family or household purposes, so an invoice between two businesses is outside it. It also aims mainly at third-party collectors, which means a business collecting its own accounts in its own name is a first-party creditor and outside the statute even on consumer accounts.

Three caveats matter, and one of them catches people out.

Collecting under a fake agency name pulls you in. If you chase your own invoices under a name that implies an outside collection agency is involved, you can be treated as a third-party collector. Send in your own name.

State law is often broader than federal law. Texas defines a debt collector without the owed-to-another limit, so the Texas act binds original creditors directly on consumer accounts. New York's General Business Law article 29-H regulates the principal creditor, meaning a New York business collecting from an individual customer is covered. If any of your customers are sole proprietors or individuals, check the rules where they are.

The TCPA does not care that it is B2B. Call and text consent rules apply to the number you are dialing, not to the nature of the debt.

None of this is legal advice. It is the shape of the question you should take to your own counsel before you set an escalation ladder that includes calls or texts.

Three situations where you should not buy this.

You have fewer than about ten open invoices a month. One person with a calendar reminder can hold that cadence by hand. Buy the software when the number of accounts exceeds what anyone can actually track, which for most teams is somewhere between 40 and 80 open items.

Your debt is already old and cold. Balances past 180 days often recover below 15%, and if the debtor has moved, gone quiet or changed entities, what you need is skip tracing and legal leverage, not another email sequence. That is a contingency agency's job and paying 30% of something beats keeping 100% of nothing.

Your invoices are wrong. If a meaningful share of your receivables is disputed because of billing errors, wrong pricing or missing documentation, automating the follow-up just industrializes the argument. Fix the invoicing first. Collections software makes a correct invoice get paid faster; it cannot make an incorrect one defensible.
