Collections & dunning
Best dunning management software for B2B invoices, and the dunning software alternatives compared on channels, ERP fit and price
The best dunning management software for a B2B company is the one that keeps every overdue invoice moving through email, text and phone until it is paid, checks your ledger before each message, and connects to the accounting system you already run. For a small or mid-sized US business on QuickBooks, Xero or NetSuite, that usually means a flat-priced AR tool with SMS and calls. For a large enterprise on SAP or Oracle, it usually means a quote-only suite such as HighRadius, Esker or Billtrust.
Most lists that rank dunning software mix two different products. Subscription dunning tools such as Churn Buster, Chargebee Retention and Stripe's retry logic exist to recover a failed card charge on a monthly plan: they retry the card and email the customer a link to update it. B2B invoice dunning is a different job. Nobody's card failed. A customer's accounts payable team has an invoice, a due date and a queue, and your reminders have to reach the right person, survive their approval process and stop the moment the payment lands. If you bill on net 30 terms, the subscription tools will not help you, however high they rank.
The table below compares the B2B side only, thirteen rows, on four things that actually decide a shortlist. Which channels each tool uses to chase (email only, SMS, or live phone calls). Which accounting systems it names publicly, because a connector you cannot confirm is a connector you will pay a consultant to build. Whether it publishes a price you can budget from. And who it was built for, since a tool designed for a 2,000-person shared service center will bury a three-person finance team in configuration.
Two patterns show up once the vendors sit side by side. Almost nobody places live collection calls: Sidetrade's Aimie is the one major suite that phones customers, and every other enterprise tool leaves calls to your collectors. And very few publish a price. Chaser, Paidnice, Chargezoom and BILL do, the enterprise suites do not, and the third-party figures that circulate for them disagree with each other by wide margins. AccountsReceivable.ai publishes its plans on the pricing page: Starter at $299 a month with email and SMS dunning on QuickBooks or Xero, and Growth at $799 a month adding live AI phone calls and NetSuite.

Why it works
What your team gets with dunning management software for B2B invoices
Invoice dunning, not card retries
Subscription tools retry a declined card and email an update link. B2B dunning chases an invoice through a customer's AP queue, which needs the right contact, a firmer tone at each stage, and a stop the moment the payment posts. Compare tools built for that job, not the other one.
Channels decide results
Email-only dunning works on customers who were going to pay anyway. The balance that ages past 60 days usually needs a text to a named person and then a phone call. Check which channels a tool actually sends on, and whether calls are placed for you or created as a task for your team.
A price you can budget from
Most enterprise dunning suites publish nothing, so you learn the price after three demos. A handful of vendors publish a rate card. When two tools do the same job, the one you can price before the first call saves a month of procurement.
What it handles
Chased, collected and reconciled on autopilot
The agent syncs your invoices, chases each one across email, SMS and phone, applies incoming payments to the right invoice, reconciles your ledger, and predicts when every customer will pay.
- An escalating dunning sequence per customer: email, then SMS, then a firmer SMS, then a live AI phone call
- Every reminder checked against your ledger right before it sends, and cancelled if the invoice is paid
- Replies read and logged as a promise to pay, a request for a copy of the invoice, or a dispute, each with a next step
- Several overdue invoices for one customer rolled into one message with one payment link
- QuickBooks or Xero on Starter, NetSuite on Growth, or start from an A/R aging export from any ERP
- Flat monthly plans from $299, SMS included, no percentage of what you collect
- 01 Sync Reads the open invoice, its terms and the billing contact from your ledger.
- 02 Chase Escalates from email to SMS to a live AI call as the invoice ages.
- 03 Track Logs replies, disputes and promise-to-pay dates against the invoice.
- 04 Apply Matches the incoming payment, reconciles the ledger and closes the invoice.
