Dunning Software: Definition, 2025 Comparison & Best-in-class Solutions for US Finance Teams

For mid-market US finance leaders, optimizing accounts receivable has become a strategic necessity. The global accounts receivable automation market is expected to grow at a CAGR of nearly 13%—from $3.8 billion in 2023 to $8.8 billion by 2030—driven by the ongoing complexity of financial transactions and the increasing need for automation across all company sizes (Grand View Research, 2024). As transaction volumes grow and the number of entities increases, manual collections are no longer sustainable—delayed payments and lack of visibility directly impact working capital. Dunning software delivers automation, real-time analytics, and audit-ready controls, helping CFOs and AR managers accelerate cash collection, ensure compliance, and provide reliable group-level reporting.

This guide highlights advanced criteria for solution selection and benchmarks the top dunning platforms on the US market for mid-sized organizations.

What Is Dunning Software? Definition & Key Selection Criteria

Definition & Core Scope

Dunning software is a robust platform tailored to the needs of mid-market finance teams, enabling automated and scalable AR collections, centralized controls, and consolidated visibility across entities—essential for optimized cash and working capital management. Beyond routine reminders, it empowers CFOs and AR managers to accelerate cash inflows, enforce group-wide credit policies, streamline audit and compliance, and deliver real-time reporting on working capital.

Core scope of supplier dunning software

• •

• Automated payment reminders (multi-channel): Deliver systematic, personalized follow-ups by email, letter, phone, or SMS based on predefined or custom schedules.

• •

• Customer payment portal: Offer a secure platform where customers can review and pay open invoices instantly.

• •

• Dispute and escalation management: Enable pausing or adapting dunning workflows for disputed invoices, with documentation and automated escalation paths for exception handling.

• •

• AR analytics: Provide comprehensive AR aging analysis, DSO tracking, debtor segmentation, and dashboards for real-time, actionable insight at both entity and group level.

How Dunning Software Works & Key Features

Modern supplier dunning software is typically cloud-based and designed to fully automate the collections process, from first reminder to final recovery or hand-off to legal action.

Key features include:

• •

• Automated, multi-step collection workflows: Schedule tailored messaging and escalation by invoice age, customer segment, legal entity or credit risk—supporting both centralized/shared service and local AR teams.

• •

• Integrated payment and dispute management: Direct links to self-service payment, configurable rules for dispute pauses, full audit trail of all actions and communications.

• •

• Advanced analytics and AR dashboard: Group-level AR aging report, DSO by entity or portfolio, root cause tracking for disputes/non-payment, export-ready audit trails.

By centralizing and automating these processes, dunning software allows finance teams to shift focus from repetitive admin tasks towards strategic analysis, exception management, and optimizing stakeholder relationships.

Key Business Benefits of Dunning software

The impact of automated dunning on DSO and liquidity is not just theoretical. According to Agicap’s recent white paper “How to Reduce DSO and improve your cash conversion cycle”, mid-market companies that implement systematic and automated customer reminder processes can reduce average days delinquent by up to two weeks and triple the likelihood of collecting late invoices within 60 days of due date.

• •

• Productivity & scalability: Automate and standardize AR collections across multiple entities, freeing teams for exception handling and strategic cash management.

• •

• Accelerated cash flow & WCR optimization: Reduce DSO and support group liquidity.

• Strategic AR oversight: Consolidated, actionable insights at group, entity, business unit, or customer level for precise credit risk management, cash forecasting, and resource allocation.

• •

• Risk mitigation & credit policy enforcement: Automated escalations and real-time debtor scoring help anticipate bad debt and optimize provisioning.

How Does Agicap Stand Out Compared to Traditional Dunning Software?

Beyond Reminder Automation: Integration with Group Treasury Management

While most dunning software in the market provides robust payment reminder scheduling and escalation management—and some include specific reporting (DSO, outstanding balance, etc.) —these solutions often remain siloed within AR management. They typically do not support group-level treasury processes or integration with wider cash flow planning.

Agicap differentiates itself by delivering a unified platform that goes far beyond traditional dunning tools, connecting AR automation directly with cash management, liquidity planning, and full treasury workflows. This all-in-one approach is particularly well-suited for mid-market companies managing multiple entities and requiring group-level financial oversight.

This eliminates batch syncing, manual spreadsheet work, and the risk of outdated projections.

• •

• ERP and bank integrations: Automated data synchronization allows up-to-date AR, cash, and payment status across all systems.

• •

• Customizable controls and workflows: Approval pathways for dunning and dispute resolution can be tailored to match internal governance and risk management requirements, enhancing compliance and audit-readiness.

• •

“At Nutrisens, we needed to manage a significant amount of data and credits. Additionally, we had a very high DSO and aimed to reduce it, but with a rather small administrative structure. Therefore, we needed to automate and review our processes. At the same time, another fundamental aspect for us was treasury management, with the need to have immediate and quick visibility of the cash situation and to make reliable forecasts both in the short and long term. All of this led us to rely on Agicap, with which we achieved very satisfactory results in a very short time.” — Roberto de Bonis, CFO, Nutrisens
