Collections & Dunning Management for B2B Credit Teams

Dunning management is the structured sequence of reminders, letters, and escalating contact a company uses to collect payment on overdue B2B invoices before an account converts to bad debt.

What Is Dunning Management, and How Is It Different From Collections?

Dunning is the specific mechanism: the scheduled letters, emails, and calls that move an invoice from "just past due" to "seriously overdue" in a predictable sequence. Collections is the broader function that dunning sits inside, covering credit holds, payment plans, write-off decisions, and the relationship calls a credit team makes outside the automated cadence. Every collections program runs a dunning process. Not every dunning process is backed by a collections team that knows when to deviate from it.

The Standard Dunning Cadence

Most B2B dunning sequences follow a similar shape: a friendly reminder a few days before the due date, a due-date notice, then escalating letters at 15, 30, 60, and 90 days past due, with tone and consequences (late fees, credit holds, collections agency referral) hardening at each stage. The exact cadence varies by industry and average invoice size, but the structure is consistent enough that most teams template it once and reuse it. Our dunning process guide walks through the full sequence stage by stage, and our dunning letter guide and collection letter templates cover what each stage should actually say.

Some accounts need a sharper tone earlier. Our demand letter guide covers the point where a dunning letter stops being a reminder and becomes a formal pre-legal notice, and our collection email templates cover the lighter-touch version most teams send before it gets there.

Why Escalating by Aging Bucket Alone Misses the Real Risk

A templated cadence treats every 60-day-past-due account the same way, regardless of why it's 60 days past due. That's the gap. An account that's always paid in 45 days and is now at 60 because of a slow internal approval process is a different risk than an account that paid in 30 days for two years and just slipped to 60 after a UCC lien filing or a sharp drop in its payment behavior across other vendors. Letters and cadences are necessary. They are not sufficient on their own, because the trigger for escalating harder, pulling the account into a credit hold conversation, or looping in a collections specialist should be the customer's financial trajectory, not which aging bucket the invoice happens to sit in this week.

Collections Software Runs the Cadence. It Doesn't Decide When to Change It.

Platforms like HighRadius and Bectran are built to execute a dunning schedule well: templated letters, automated reminders, payment portals, and workflow routing that takes manual follow-up off a collector's plate. That's real, useful automation. What it isn't is a decision engine. These platforms schedule and send; they don't reprioritize an account's position in the queue because a customer's underlying financial position changed. A collector using either tool still has to notice, on their own, that an account's risk profile shifted before the next scheduled step fires.

Building an Escalation Path Around Financial Trajectory Instead of Days Overdue

An escalation path built around trajectory starts with the same cadence most teams already run, then adds a trigger layer on top of it. If continuous monitoring on an account surfaces a new UCC lien, a payment pattern across other vendors stretching from 20 days to 50, or a credit score drop, that account should jump ahead in the cadence regardless of what day-count bucket it's currently sitting in. The point isn't to abandon the standard letter sequence. It's to stop treating every account in the same bucket as an identical risk when the underlying signal says otherwise.

Metrics That Actually Show Whether Dunning Is Working

Letter volume and open rates measure activity, not outcomes. The number that matters is how long it actually takes to collect once an invoice goes overdue, tracked as a trend rather than a single snapshot. See our average collection period guide for the calculation and what a worsening trend usually means before it shows up anywhere else in the financials.

Where Credit Pulse Fits

Credit Pulse doesn't replace a dunning cadence or a collections team, and it isn't a scheduler competing with the platforms built for that job. Its research agents run continuous monitoring on an account between review cycles, so a deteriorating signal surfaces as a trigger to escalate ahead of schedule instead of waiting for the next quarterly review or the next aging-bucket threshold to hit. That pairs with the broader workflow automation covered in our AR automation guide, and with the account-level view in our AR collections guide.

Frequently Asked Questions

What is a dunning letter?

A dunning letter is a written notice sent to a customer about an overdue invoice. Dunning letters typically escalate in tone and consequence across a sequence, from a friendly reminder to a formal notice of credit hold or collections referral.

How many dunning letters should a B2B collections cadence include?

Most B2B cadences run four to six touchpoints: a pre-due reminder, a due-date notice, and escalating letters at roughly 15, 30, 60, and 90 days past due. The right number depends on invoice size and industry norms, not a fixed standard.

What's the difference between dunning and collections?

Dunning is the scheduled sequence of reminders and letters. Collections is the broader function, including credit holds, payment plans, write-off decisions, and the judgment calls a credit team makes outside the automated sequence.

Should every overdue account follow the same escalation schedule?

Not necessarily. An account whose financial position is deteriorating, shown through a new lien filing, a slowing payment pattern with other vendors, or a credit score drop, is a different risk than an account that's simply a few days later than usual, even if both sit in the same aging bucket.

Does dunning management software replace a collections team?

No. Platforms like HighRadius and Bectran automate the sending and scheduling of the dunning cadence, which removes manual follow-up work. They don't make the judgment calls about when an account's risk has changed enough to warrant stepping outside the standard schedule; that still requires a person or a monitoring layer watching for the signal.
