For professional services firms, revenue is earned, but cash flow is collected. The gap between invoicing and payment, measured by Days Sales Outstanding (DSO), is a critical operational metric. Yet, managing this gap often relies on manual, inconsistent processes: spreadsheets, calendar reminders, and ad-hoc emails from finance staff or even firm partners.

This approach doesn't scale. It introduces human error, strains client relationships, and creates a drag on working capital. A firm with $10M in annual revenue and a 60-day DSO has over $1.6M tied up in receivables. Reducing that by just 10 days unlocks nearly $275,000 in cash.

This guide moves beyond generic feature lists. We will analyze the 12 best accounts receivable software solutions specifically through the lens of a finance operator at a professional services firm. We'll evaluate them on their ability to deliver measurable outcomes: reduced DSO, improved cash flow, and streamlined operations without alienating valuable clients.

We will focus on the practical application of accounts receivable automation, including AI AR automation and seamless integration with platforms like QuickBooks. For a deeper dive into the foundational concepts, this guide on what business process automation is and its benefits offers a comprehensive overview.

Each review includes screenshots, direct links, and a clear-eyed assessment of where each platform excels and where it falls short. You will gain the clarity needed to select a tool that provides control over your most critical asset: cash.

1. Resolut: AI-Powered Orchestration for End-to-End AR

Resolut stands out as a premier choice for professional services firms by moving beyond simple reminders into a full-cycle, AI-driven Accounts Receivable Operating System. It’s designed for leaders who view cash flow not just as a collections problem, but as an operational system to be optimized. The platform unifies the entire invoice-to-cash lifecycle, from proactive credit risk assessment and intelligent billing to automated, personalized collections and instant cash application.

This end-to-end orchestration provides a single source of truth, connecting finance, sales, and client management teams. For CFOs and controllers, this delivers unprecedented control and visibility over working capital, transforming AR from a reactive, manual function into a predictable, data-driven engine for cash flow.

Why Resolut is a Top-Tier AR Solution

Resolut's core strength is its AI-powered intelligence, which proactively identifies at-risk invoices based on payment patterns, client history, and communication engagement. This allows AR teams to intervene before an invoice becomes delinquent, preserving cash flow and client relationships simultaneously.

The platform's omnichannel outreach is a significant differentiator. It doesn't just send generic emails; it personalizes the tone, timing, and channel (email, SMS) for each client, dramatically improving engagement and payment rates.

Key Takeaway: Resolut’s orchestration model provides a strategic advantage by using AI to manage the entire AR process, not just isolated tasks. This leads to measurable reductions in Days Sales Outstanding (DSO) and frees up finance teams to focus on higher-value analysis.

Standout Features & Practical Applications

• Intelligent Legal Escalation: For persistently late accounts, Resolut deploys a unique "voice of a lawyer" communication sequence. This measured, firm approach has proven highly effective in recovering aged debt without immediately resorting to costly external collections agencies.

• Flexible Automation Modes: Users can choose between Autopilot for full, hands-off automation on lower-value invoices, and Co-pilot, which provides human-in-the-loop control for high-value or sensitive client accounts. This flexibility ensures automation enhances, rather than replaces, strategic human oversight.

• Automated Cash Application: The platform connects directly with its consumer-grade payment portal (accepting cards, bank transfers, and digital wallets) to instantly reconcile payments against open invoices. This eliminates manual cash posting, reduces errors, and provides a real-time view of cash positions.

• Deep ERP Integration: Resolut offers robust integrations with systems like QuickBooks, ensuring that all AR data is synchronized and accurate, which is critical for reliable financial forecasting.

Implementation and Governance

Implementing a full-cycle system like Resolut requires an initial setup period to integrate with your existing ERP and billing systems. The effectiveness of its AI also hinges on the quality of historical invoice and payment data. To maximize ROI, firms should establish clear governance protocols, particularly for escalation workflows, to ensure automated actions align with client relationship strategies. The platform is best suited for professional services firms managing a significant volume of invoices where manual follow-up becomes a major operational bottleneck.

2. BILL (formerly Bill.com)

BILL is an end-to-end financial operations platform known for its stronghold in the US small and mid-market business sector, particularly among accounting firms and their clients. Its AR module provides a straightforward, effective solution for invoice creation, automated reminders, and payment processing, making it a solid choice for companies needing a reliable, all-in-one system for both accounts payable and receivable. The platform's primary strength is its direct, two-way synchronization with major accounting systems like QuickBooks and Xero.

This deep integration ensures that invoice statuses and payment data flow seamlessly, reducing manual reconciliation and providing a single source of truth for cash flow. This functionality is a key reason why it is often considered one of the best accounts receivable software options for businesses already embedded in the QuickBooks ecosystem. The platform also offers a customer portal, allowing clients to view invoices and make payments directly via ACH or credit card.

Key Features and Considerations

• Best For: SMBs and mid-market firms, especially those using accounting partners who are part of the BILL ecosystem.

• Strengths: BILL's pricing is transparent, with clear monthly fees per user and published transaction costs for ACH and card payments. This predictability aids in total cost of ownership (TCO) analysis. The widespread adoption among accountants also simplifies collaboration.

• Limitations: While effective, its AR automation is more rules-based than the AI-driven dunning of specialized platforms. The per-user pricing model can become costly for larger AR teams, and standard credit card processing fees (2.9% + $0.30) apply. Exploring the broader benefits of accounts receivable automation can help determine if BILL's feature set meets your firm's specific needs for reducing DSO.

It is designed to foster better customer relationships through a branded, self-service online portal where clients can view invoices, ask questions, and make payments. This focus on collaborative AR makes it a compelling choice for mid-market and enterprise companies looking to reduce friction in the invoice-to-cash cycle.

The platform's strength lies in its comprehensive B2B payment capabilities, supporting ACH, virtual cards, and credit cards with a focus on Level III data processing to lower interchange rates. Its AI-powered cash application module automates the matching of payments to open invoices, a significant pain point for finance teams dealing with high transaction volumes.

Key Features and Considerations

• Best For: Mid-market to enterprise-level B2B companies with complex payment acceptance needs and a high volume of invoices.

• Strengths: Deep B2B payments functionality and the collaborative customer portal are significant differentiators. The platform's ability to scale and integrate with multiple ERP systems provides a solid foundation for growing businesses aiming to centralize their AR operations and improve cash flow.

• Limitations: Versapay does not publish its pricing, requiring direct engagement with their sales team for a quote, which complicates initial TCO assessment. The implementation effort can be substantial depending on the complexity of the existing ERP and financial tech stack.

• Strengths: The platform's deep focus on AR provides granular control over collections strategies and cash application rules. Its robust integration capabilities and strong implementation support help ensure a smooth transition from existing accounting or ERP systems.

• Limitations: Pricing is not publicly listed and requires a sales-led procurement process, which can lengthen the evaluation cycle. Some of the more advanced features and analytics modules may be add-ons that increase the total cost of ownership.

5. HighRadius

HighRadius offers an enterprise-grade, modular suite for managing the entire credit-to-cash cycle. It's a powerful solution designed for mid-market and large organizations facing complex AR challenges, such as high volumes of deductions, multi-ERP environments, and global operations. Unlike all-in-one platforms, HighRadius allows companies to deploy specific modules for Credit, Collections, Cash Application, and EIPP, or the full end-to-end system. This makes it a scalable choice for finance leaders looking to solve a specific pain point before committing to a full transformation.

The platform’s core strength lies in its use of predictive analytics to prioritize collection activities and automate cash application, significantly reducing manual effort for AR teams. Its robust EIPP portal provides a self-service hub for customers to view invoices, raise disputes, and make payments, improving the client experience while accelerating cash flow. For businesses with intricate deduction and reconciliation needs, HighRadius provides one of the best accounts receivable software solutions due to its specialized, AI-driven functionality.

Key Features and Considerations

Its enterprise-level functionality for handling deductions and applying cash is mature and highly effective.

• Limitations: Pricing is available only by quote and is tailored to enterprise budgets, making it less accessible for smaller firms. Implementation is a significant project that typically requires dedicated IT resources or a third-party implementation partner, unlike the plug-and-play setup of SMB-focused tools.

Quadient AR, formerly known as YayPay, is an accounts receivable automation platform designed for mid-market and enterprise B2B companies. It focuses heavily on enhancing the productivity of collections teams through a centralized workspace, automated communication workflows, and detailed performance analytics. The system integrates with major ERPs to provide a unified view of customer data, invoice status, and communication history, enabling collectors to manage their portfolios more efficiently.

Its core value lies in structuring the collections process with clear tasking, automated reminders, and promise-to-pay tracking. A key differentiator is its focus on demonstrating measurable outcomes, with customer case studies often highlighting significant reductions in days sales outstanding (DSO) and improved cash flow. The platform's customer portal also facilitates self-service, allowing clients to view invoices, make online payments via ACH or card, and manage disputes, which accelerates the payment cycle. This makes it a strong contender for the title of best accounts receivable software for firms prioritizing collector efficiency.

Key Features and Considerations

• Best For: Mid-market and enterprise finance teams aiming to structure and scale their collections activities and improve team productivity.

• Strengths: The platform provides documented ROI and customer proof points, giving finance leaders confidence in its potential impact. The user interface is designed for ease of use, specifically for collections teams managing large portfolios of accounts.

8. Chargebee Receivables

Chargebee Receivables is an accounts receivable automation platform specifically engineered for subscription and recurring-revenue business models. It extends the functionality of Chargebee Billing by adding sophisticated dunning management, collections workflows, and cash application tools tailored to the complexities of SaaS and usage-based companies. The platform excels at managing the nuanced AR challenges that arise from prorated billing, mid-cycle upgrades, and recurring invoices.

For companies already embedded in the Chargebee ecosystem, Receivables offers a seamless, native integration that provides a unified view of the entire customer revenue lifecycle, from billing to final payment collection. Its primary differentiator is this deep focus on subscription logic, which informs its automated reminders, payment retries, and customer portal functionalities. This specialization makes it a compelling choice for businesses where managing churn and customer lifetime value is directly tied to the payment experience.

Key Features and Considerations

• Best For: SaaS, subscription, and recurring-revenue businesses already utilizing Chargebee Billing for their core billing operations.

• Strengths: The platform's design is inherently aligned with the nuances of subscription finance, such as managing failed payments to prevent involuntary churn. It offers a natural, streamlined workflow for existing Chargebee users, minimizing the need for complex third-party integrations.

• Limitations: Its value is significantly diminished for companies with straightforward, non-recurring invoicing needs. Public pricing is not available for the Receivables module, requiring engagement with a sales team to determine cost, which can complicate initial TCO calculations. This focus on a specific niche means it may be less flexible than other, more generalized AR platforms.

The platform excels at core AR functions like creating professional invoices, setting up recurring billing cycles for retainers, and automating payment reminders, making it a strong contender for companies seeking an all-in-one financial system without a significant investment.

Its primary appeal lies in its accessibility and rapid time-to-value. Businesses can quickly get started, connect payment gateways, and give clients access to a self-service portal to view and pay invoices. This straightforward functionality, combined with multi-currency support, positions Zoho Books as one of the best accounts receivable software options for growing businesses managing their finances in-house and needing a system that can scale with them from the ground up.

Key Features and Considerations

10. Salesforce AppExchange

The Salesforce AppExchange is not a single AR software but an official marketplace where companies can discover, trial, and install hundreds of finance apps that are either native to or integrate with Salesforce CRM. For businesses where the AR and collections processes are deeply intertwined with sales and customer service teams operating within Salesforce, the AppExchange provides a centralized and vetted ecosystem. It allows finance leaders to find tools that can bridge the gap between sales data and financial data, providing a more holistic view of the customer lifecycle.

This approach is powerful for organizations that need AR workflows to trigger actions or be informed by activities in the CRM, like pausing collections outreach for a client with a critical open support ticket. By leveraging apps from this marketplace, you can find solutions ranging from simple invoice connectors to full-fledged accounts receivable automation platforms that live within your existing Salesforce environment, streamlining data flow and procurement through a single, familiar hub.

Key Features and Considerations

• Best For: Companies heavily invested in the Salesforce ecosystem where AR, sales, and service functions must be tightly aligned.

• Strengths: The platform offers a pre-vetted selection of tools with user ratings and reviews, which can simplify the initial research phase. Finding a solution that works natively within Salesforce can dramatically reduce integration complexities and create a single source of truth for customer financial health.

• Limitations: Quality and pricing vary dramatically between applications, and many listings still require direct vendor contact for a demo or quote. Without a clear strategy, there is a risk of "app sprawl," creating overlapping functionalities with your existing ERP or accounting software. Careful evaluation is needed to ensure a new app truly complements the existing finance stack rather than complicates it.

11. Microsoft AppSource

Microsoft AppSource is not a standalone AR software but the official marketplace for finding applications that integrate directly with Microsoft Dynamics 365 and Business Central. For CFOs and finance leaders operating within the Microsoft ecosystem, AppSource is the essential starting point for discovering vetted accounts receivable automation tools, connectors, and payment solutions. It provides a curated environment where users can confidently find and deploy apps directly into their existing ERP.

This direct integration model is a significant advantage, as it simplifies security and compliance vetting while ensuring that any chosen AR solution will function seamlessly with the company's core financial system. AppSource listings detail supported editions, available trials, and user reviews, offering a transparent way to compare different vendors. For any firm committed to Dynamics 365, using this marketplace to find the best accounts receivable software is a strategic first step to guarantee compatibility and streamline implementation.

Key Features and Considerations

• Best For: Companies of all sizes that use Microsoft Dynamics 365 Business Central or Finance as their primary ERP.

• Strengths: As the official marketplace, it ensures a high degree of integration reliability and simplifies the security review process. The ability to filter apps by certification, rating, and industry helps finance teams narrow down options efficiently, saving significant time in the procurement cycle.

• Limitations: It's a marketplace, not a product, so quality and features vary significantly between listings. Many vendors do not publish pricing directly on their AppSource page, requiring direct contact for a quote. This can complicate initial cost comparisons and TCO analysis.

12. G2 (Accounts Receivable category)

G2 is not an AR software itself, but a peer-review marketplace that has become an essential research tool for finance leaders. Its Accounts Receivable category provides continuously updated rankings, real-user reviews, and detailed comparison grids across the entire spectrum of AR tools, from simple invoicing apps to enterprise-grade automation suites. For CFOs and controllers, it serves as a critical first step to shortlist vendors and validate marketing claims against actual user experiences before committing to a purchase.

The platform allows users to filter solutions by company size, industry, and specific features, making it easier to identify the best accounts receivable software for a particular use case, like AR software for professional services firms. Its Leader and Momentum grids offer a visual snapshot of market presence and user satisfaction, helping you quickly identify established players and emerging innovators. This data-driven approach is invaluable for building a business case and comparing how different platforms perform in real-world scenarios.

Key Features and Considerations

Top 12 Accounts Receivable Software Comparison

Choosing the Right System: From Automation to Orchestration

The journey through the landscape of the best accounts receivable software reveals a clear evolution. The objective is no longer simple automation; it's about achieving intelligent orchestration of the entire invoice-to-cash cycle. Sending templated reminders is a solved problem. The real challenge, especially for professional services firms, is maintaining control, predictability, and client relationships while accelerating cash flow.

As we've analyzed platforms from dedicated AR solutions like Versapay and HighRadius to broader accounting systems like Zoho Books, a central theme emerges. The most effective systems provide not just tools, but a strategic framework. They offer visibility into payment behaviors, identify at-risk invoices before they become delinquent, and tailor communications to the client relationship.

Key Takeaways for Finance Leaders

For CFOs and Controllers, the decision-making process must be grounded in measurable outcomes. Before committing to a platform, model the financial impact. A 10-day reduction in DSO for a firm with $10 million in annual revenue unlocks over $270,000 in working capital. This is the level of analysis required.

Your evaluation should prioritize three core areas:

• Integration Depth: A superficial connection to your ERP or accounting system like QuickBooks is insufficient. True QuickBooks AR automation requires a two-way sync of invoice data, payments, and customer information to prevent manual reconciliation.

• Customization and Control: Can you define unique collection cadences for different client segments? Can you easily pause communications for a sensitive account? For professional services, this level of control is non-negotiable.

• Client Experience: The portal where your clients view invoices and make payments is an extension of your brand. A clunky, confusing, or unreliable payment experience reflects poorly on your firm and can create friction that delays payment.

Visual Idea 1: A flowchart titled "AR Orchestration vs. Automation." One side shows a linear, simple path (Invoice > Reminder > Payment). The other shows a dynamic, multi-branched path (Invoice > Risk Analysis > Segmented Outreach > Payment Portal > Automated Cash App > Performance Analytics).

From Evaluation to Implementation

Selecting the right accounts receivable software is only the first step. A successful implementation requires a clear strategy. Start by mapping your current AR process and identifying the primary bottlenecks. Is it invoice delivery, manual follow-up, or cash application? This diagnosis will clarify which features to prioritize during setup.

Engage your team early. The AR specialists and accountants who will use the system daily are your most valuable resource. Their feedback on usability and workflow integration is critical for adoption. A powerful tool that sits unused delivers zero ROI.

Finally, set clear success metrics before you go live. Target a specific DSO reduction, a percentage decrease in time spent on collections, or an improvement in your collection effectiveness index (CEI). Track these KPIs from day one to quantify the value of your investment and make data-driven adjustments.

Visual Idea 2: A cinematic-style image of a CFO at a large touchscreen, manipulating a dashboard that visualizes cash flow, DSO trends, and at-risk accounts, demonstrating control and foresight.

The ultimate goal is to transform accounts receivable from a reactive, administrative burden into a strategic, data-driven function. The right platform doesn't just chase late payments; it provides the intelligence to prevent them from happening in the first place. It builds a predictable cash flow engine, giving you the financial clarity and control needed to scale your firm with confidence.
