Disclosure: Abivo is our product. Facts about other tools come from their own websites as of October 2026.
The short answer: The right B2B collections management software depends on who does the chasing. A solo bookkeeper or controller needs follow-up that runs without them, which is where Abivo's AI agent (calling, texting and emailing customers in your company's name) or Chaser's automated reminders fit. A team of 2 to 5 collectors needs shared worklists, task assignment and a common inbox, which Upflow, Kolleno, Anytime Collect and Tesorio describe. An enterprise shared services center needs prioritization at scale across entities and regions, which is the focus of HighRadius, Sidetrade and Growfin. This page covers commercial, invoice-based collections between businesses, not consumer debt collection agency software.

Match the tool to your team setup
Solo bookkeeper, controller or office manager
When one person handles AR alongside payroll, payables and the close, collections is the job that slips. The test is simple: does follow-up still happen during month-end? Look for software that sends or makes contact without being prompted, logs what customers say and pulls you in for disputes or a customer who wants a person. Abivo and Chaser fit here. Many solo operators start with the collections software for small business checklist.
Two to five collectors
Small teams fail at hand-offs: two people calling one customer, unchecked promises to pay, or a dispute stuck in one inbox. You need account ownership, task assignment, a shared view of every touch and promise tracking. Upflow, Kolleno, Anytime Collect and Tesorio are built around these. Our collections team structure guide covers how to split portfolios.
Enterprise shared services
Shared services centers handle many entities, currencies and languages with standardized processes. The needs shift to scoring thousands of accounts, routing work by availability, manager oversight by collector and consistent rules across regions. HighRadius, Sidetrade and Growfin describe these capabilities.
Abivo
Abivo is AI collections software for B2B finance teams. Its AI agent, Kate, calls, texts and emails customers about overdue invoices in your company's name, records promises to pay, disputes and next steps, and hands disputes and requests to speak with a person to your AR team with the full history.
For a solo operator, follow-up keeps running during the close; for a small team, Kate covers the long tail while collectors handle accounts that need judgment. You set the cadence per account or segment, pause any single invoice and flag key accounts so a named owner handles them. Reminders name invoice details such as job, site, PO or billing period, and one message can cover every open invoice on an account.
Multi-entity teams keep each subsidiary separate, and Abivo works with customers in over 50 countries and in any currency. It connects with QuickBooks, Xero, NetSuite, Sage Intacct, Microsoft Dynamics 365 Business Central, SAP and Chargebee, or an aging report export, and does not replace your accounting system, invoicing, payment processing or cash application. "OFS Group, a fire protection contractor, collected $842,518 in its first four months with Abivo" (case study). Read how AI collections calls work.
Choose it when: you do not have collectors to spare, or your collectors spend their day on routine follow-up instead of disputes and key accounts.
Chaser
Chaser markets credit control software with reminders by email, SMS, automated phone calls and letters, plus in-app calling and an AI email generator. You can build multiple reminder schedules, including one per customer, and reminders stop once an invoice is paid. It integrates with Xero, QuickBooks, Sage, NetSuite, Business Central and SAP. Chaser also sells outsourced credit control through Chaser Care. See our Chaser alternative page.
Choose it when: you are a small business that wants templated reminders now and the option to outsource credit control later.
Anytime Collect
Anytime Collect says its product "tells you who to call, what to email" through rule-based, prioritized action lists for each user. The Standard Edition adds dispute tracking with reason codes, expected payment records, daily automated past-due emails, an optional bill pay portal and cash forecasts based on each customer's payment history. It can run in the cloud on Microsoft Azure or, in its Enterprise Edition, on-premise. Its site targets growing companies managing AR, credit and collections.
Choose it when: your collectors want a structured daily call and email list and you prefer a choice of hosting.
Upflow
Upflow uses Smart Rules to assign customers to workflows, with outreach by email, SMS, calls and letters. It offers a centralized AR inbox shared across teams, @mentions in-app, by email and in Slack, role-based permissions and unlimited users. Its collection agents can run "from fully autonomous to suggestions only," set skill by skill, and sensitive cases escalate to a collector.
Choose it when: you have a few collectors who want one shared inbox and control over how much AI does.
Kolleno
Kolleno's team and task management lets you assign tasks to users, auto-assign them by segment, account size or workload, and limit each user to a client portfolio. Collectors get a prioritized daily to-do list, reminders for missed promise-to-pay dates and a single activity feed of emails, calls, SMS and notes. Access levels are admin, member and viewer. It lists NetSuite, QuickBooks, MS Dynamics, Xero and Sage integrations.
Choose it when: you need clear ownership and permissions across a small team.
Tesorio
Tesorio describes a Collections Agent that scores open invoices on payment history, risk and aging, reads and classifies incoming AR emails, and drafts replies for one-click sending or review. Worklists update in real time, and dashboards show contact rates and promise-to-pay conversion by collector. It lists NetSuite and Sage Intacct integrations.
Choose it when: your team collects by email and wants AI to sort the inbox and build the worklist.
Growfin
Growfin positions itself as "autonomous collections for high-velocity AR." It assigns customer health scores from live factors such as broken promises to pay, segments accounts into low-touch and high-touch strategies, and runs workflows that trigger follow-ups, escalations and assignments. An AI-led inbox drafts replies. It lists a NetSuite app and Salesforce, HubSpot and Slack integrations.
Choose it when: you manage high invoice volume and want risk-based segmentation across collectors.
Sidetrade
Sidetrade calls Augmented Collection an "AI-guided collections automation app." Its AI, Aimie, chooses the action, timing and channel for each invoice, collectors get daily prioritized agendas, and disputed invoices leave the dunning flow for the right team. Business rules and escalation policies apply across regions and entities.
Choose it when: you run collections across several regions or entities and need consistent rules with local flexibility.
HighRadius
HighRadius gives each account a collections score from ML models, stack-ranks customers for collectors, tracks promises to pay and predicts payment dates. It describes AI agents for worklists, dunning emails, in-app outbound calling and dispute prevention, plus smart account assignment by availability and manager review by collector. It lists SAP, Oracle, NetSuite, Microsoft Dynamics 365 and QuickBooks Online.
Choose it when: you run a shared services center or large AR team that needs scoring, routing and oversight at scale.

How to choose collections management software
Count the hours, not the invoices. Ask who will actually work the tool each day. A platform built for 20 collectors can sit unused by one controller.
Map your hand-offs. Write down who handles disputes, who approves payment plans and who owns key accounts. The software should route to those people by name.
Check promise follow-through. A promise to pay is worth little unless the tool chases it the day after it is missed. See our guide to promise to pay tracking.
Decide who makes the calls. Some tools give collectors a call list and a dialer; others place the calls. If your team cannot add phone time, that decides a lot.
Test on real accounts. Bring your aging report and a handful of difficult customers to every demo. For more comparisons, see collections software for AR teams and our accounts receivable software guide by business type.
