What Is the Best AR Software to Generate Cash Flow?

B2B payments is a $98 trillion market growing 12% a year, but 67% of finance leaders say their customers are paying slower. That’s a problem: payment volume is growing, but suppliers often don’t know when the cash they’ve earned will actually show up in the bank. Buyers aren’t paying as fast. Plus, inefficient accounts receivable (AR) processes can trap cash. The solution isn’t just AR software that sends more payment reminders. It’s faster cash flow generation – turning earned revenue into usable cash as quickly as possible.

AR Software: 6 Capabilities for Cash Flow Generation

These are the six capabilities that define AR software built to generate cash flow:

1. One platform connecting invoices, payments, credit, collections, and cash application so you can see how cash actively moves across the entire order-to-cash cycle.
2. Forecasting built on buyer behavior data, so you know the number you’re seeing is dependable and defensible. 
3. Credit decisions that adjust as buyer risk changes, so exposure stays with cash-healthy accounts you can count on.
4. Collections prioritization strategy, so you’re focusing on the greatest area of risk and recovery and not just the invoices that have been aging longest.
5. AI that runs behind the scenes, continuously monitoring payment trends and invoice engagement behavior as well as flagging risk as soon as it happens so you can prevent it from turning into bad debt.
6. AI that plugs into your AR data, so you can ask questions in plain language about your cash flow and get instant insights without having to toggle between systems or pull manual reports and aggregate data.   

The best AR software doesn’t just automate payment processes. It works across every AR function to convert receivables into working capital that your business can deploy for growth. In a Billtrust study, 100% of finance leaders who invested in AR software reported measurable gains including faster payments, lower costs, and accelerated cash flows.

What’s the Best AR Software for Seeing How Cash Moves Across the O2C Cycle?

Most AR automation only covers part of the order-to-cash (O2C) cycle. Invoicing, collections, and credit tools work. But all too often, someone on your finance team still has to stitch together siloed data to answer a simple question.

That’s especially problematic for cash generation, because the earliest sign that cash is at risk rarely shows up in the function you’d expect. Let’s say you have a buyer heading toward a collections problem. The first signal might show up somewhere else entirely – like a payment method change or a rising trend in credit utilization. Those signals appear weeks before an overdue invoice reaches an aging report. Point solutions can’t triage the information to catch the trend, because each solution is only watching its own piece of the larger puzzle.

The best AR software runs invoicing, payments, credit, collections, and cash application on a single platform, built on one shared set of data. The result is cash flow forecasting, credit decisioning, and collections procedures which all draw from the same live picture of every buyer instead of separate systems that guess at different parts of the story.

What’s the Best AR Software for Cash Flow Forecasting?

Almost any AR software can produce a cash flow forecast.  But how much work goes into it? And, is it even accurate? Research shows only 28% of cash forecasts land within 10% of accuracy.

It doesn’t help to know about a problem after it’s already done damage. You need to know what’s about to happen – that’s what the best AR software should do. Billtrust’s Cash Flow Forecasting makes that happen with a self-updating 13-week AR cash forecast. This forecast is refreshed daily and built from a live open AR balance file that captures buyer behavior across every AR function and every payment channel – not just transactions that run through our platform. The forecast also comes with a confidence range, so you see not just a number but how much to trust it.

AR Software Should Flag these Cash Flow Threats

Underneath the forecast sit five agentic agents monitoring buyer payment behaviors that can slow the flow of working capital:

1. Days-to-pay drift
2. Rising delinquency
3. Autopay unenrollment
4. Shifts in how a buyer pays
5. Shifts in what payment method a buyer uses

The cash flow forecast automatically updates as these signals move. There’s also a Top Buyer Impact Dashboard that shows the top 5% of accounts moving your forecast most, and by how much.

This is what we mean when we say not all AR software is designed to generate cash flow. Look beyond surface-level claims. Does the system tell you what happened last month, or can it tell you which accounts are about to change next quarter’s number and why?

What’s the Best AR Software for Credit Risk Management to Free Up Capital Sooner?

Traditional credit risk management assumes nothing will change once a limit is set. But time doesn’t freeze. In fact, financial conditions can shift fast enough that a cash-healthy company becomes risky without you even knowing it. If you’re not keeping a watchful eye, exposure will build and liquidity will stall. 

Agentic AI changes the game with dynamic risk decisioning, and it’s something the best AR software should offer. Billtrust’s Agentic Credit Lines continuously analyzes dozens of data points – payment history, credit utilization, overdue balances, dispute trends, and external credit bureau data – to sharpen credit allocation recommendations and risk scores for every buyer in your portfolio.

This has a direct impact on cash flow generation.

What’s the Best AR Software for Collections So Receivables Don’t Turn into Bad Debt?

Collections is where the rubber meets the road. Cash either gets freed or lost for good. The best AR software isn’t limited to a one-size-fits-all dunning schedule because all that does is delay the moment you realize the payment will never come.

• Collections strategies need to adjust as buyer behavior changes because that’s the earliest indicator of risk. 
• Your most skilled collectors should concentrate on where the most dollars and risk are, instead of low-risk accounts where payment reminders can be automated.
• Outreach should run based on data-backed best practices, so you’re reaching the right person, at the right time, on the right channel, with the right level of assertiveness.  

Billtrust’s Agentic Procedures replaces the static dunning schedule with behavior-based segmentation that drives collections prioritization. Agentic agents group buyers into different risk categories based on monthly payment volume and days delinquent per month and then recommends targeted outreach strategies for each, prioritizing those categorized as highest risk. Recommendations shifts with buyer behavior. That way, the strategy doesn’t go stale the way a fixed dunning schedule does.

As always, a person still runs the process. Every recommendation can be accepted, rejected, or customized before it goes out. Essentially, the model sharpens the strategy without taking control away from the collector. The result shows up directly in recovered cash.

What’s the Best AR Software that Uses AI for Cash Flow Generation?

We’ve explored a lot of AI capabilities already. Here’s one we haven’t covered yet, and the best AR software should absolutely have it: MCP servers.

AI has gotten remarkably good at answering questions, but only about the data it can see. For an AI tool like Claude or Copilot to give you insights about your cash flow, you’d need to feed it your AR data. That means spending the next few days exporting reports, copying numbers over, and re-explaining context because the AI has no ongoing memory and no access to what’s happening as it happens. That creates a bottleneck: the wall between the AI and the data it needs to be more helpful.

To break this wall, Billtrust recently launched the first Model Context Protocol (MCP) server in AR automation. Claude and Copilot get a live, secure connection straight to AR data so a CFO asking about this quarter’s DSO trend gets a plain-language answer instantly instead of waiting days for a manual report to be compiled. An AR manager doesn’t need five logins and five tabs open to see which accounts are trending late. The AI isn’t guessing or working from exports that might need data reconciliation, because it’s looking at what’s happening right now across all AR functions.

Whatever you need to know, you can — all without having to bring the AI up to speed or hop back and forth between your AR software and other financial applications.

Here are some important things to know:

• Every question you ask gets logged so there’s a full record of who asked what.
• Billtrust runs the MCP server itself, so your data never leaves our own secure environment. Just as importantly, it stays walled off from other customers’ data.
• Your raw financial data is never exposed to Copilot or Claude. They work with a clean summary instead.

Where AI and MCP is Headed Next

The next phase of innovation moves from answering questions to executing tasks. Soon, finance teams will be able to use their AI tools to send payment reminders, apply payments, flag discrepancies, and escalate disputes directly from Claude or Copilot.

A one-time AI question or request can even become a standing rule to monitor and consistently act on. For example, you tell Claude or Copilot, “Whenever an account hits 45 days past due, send a reminder.” From then on, Billtrust’s platform monitors for that condition continuously and acts on it every time it occurs, logging each instance for audit.

Once again, we see a substantial difference between AI that merely assists and next-gen AI that generates cash flow.

What Should You Compare When Evaluating AR Software?

Here’s a short list of questions to consider.

• Does it run one platform for all AR functions or does it stitch tools together? If invoicing, payments, credit, collections, and cash application live in separate systems, the platform can’t see the nuance or patterns that matter for generating cash.
• Does it forecast cash flow from live behavior? A forecast built on static DSO models is already out of date by the time it reaches the board.
• Does it manage credit proactively? By the time a late payment triggers a manual review, the exposure has been building to a breaking point.
• Can you defend AI’s numbers? Transparency and explainability are paramount. Here are 4 more things you need to trust AI.
• Does it meet your team where they already work? The last thing you need is one more login. Your AR software should work with the AI tools your team already has open all day.
• Does it start smart? This is a big one. A platform built on a large network of buyer payment behavior starts smarter on day one than one built from scratch.

Any AR software can answer “yes” to one or two of these. The ones worth shortlisting answer “yes” to them all.

Which AR Software Best Generates Cash Flow?

Billtrust scores “yes” across the board because it was built differently than most AR software – not just to automate AR tasks, but to make every dollar a business earns cash it can use to grow.

Our platform runs the full order-to-cash cycle on a single system, built on the largest buyer data network of 13 million buyers and more than $1 trillion invoiced annually. Cash flow forecasting is based on vast real-time data and delivers a dynamic 13-week view. Agentic Credit Lines catches risk before it reaches the forecast. And with our MCP server, that entire picture is just a question away – available inside the AI tools your team already uses.

It’s an entirely different approach to cash flow generation, with entirely different results – an average 384% ROI, our customers report.
