Get started
TL;DR: Legacy, software-first platforms organize the work for the AR team to execute, providing structure and visibility while collectors still chase every invoice. Full-stack AI platforms like Stuut execute the work autonomously, contacting customers across email, SMS, and voice, matching payments, and resolving deductions, escalating to human collectors only when complexity demands it. Stuut onboards in days rather than months, requires no ERP modification or middleware development, and customers report an average 37% DSO reduction across live implementations. The result is 70% fewer manual tasks and collections coverage that scales without adding headcount.
For mid-market manufacturers and distributors, the gap between revenue earned and cash in the bank often comes down to how effectively the AR team can collect. Aging invoices, unapplied payments, manual portal logins, and under-resourced long-tail accounts all compound into DSO figures that trap working capital for weeks longer than necessary.
This guide breaks down how modern AR collections software addresses those specific challenges, what separates legacy platforms from full-stack AI, and how to evaluate, implement, and build team buy-in for a platform that actually executes the work.
How AR Automation Platforms Support the Workflow
What AR Software Does
Accounts receivable collections software reads invoice data from the ERP, tracks aging buckets (0 to 30, 31 to 60, 61 to 90, and 90+ days), and centralizes customer communication history in one system. Without dedicated AR software, collections teams export aging reports to Excel, manually sort accounts by priority, and maintain contact notes in personal spreadsheets that lack centralized visibility.
A centralized system of record changes that dynamic, giving the AR Director a single dashboard showing every open invoice, every communication sent, and every promise-to-pay date logged. The operational question isn't whether to use software for AR management: It's which type of software does the work.
Beyond Basic AR Automation
Basic AR automation handles scheduled email sequences and aging report generation, but collectors still execute every other step manually. When a payment arrives with no remittance, a human researches it. When an invoice needs uploading to Ariba, a human logs in. As Stuut's collections email automation analysis describes, collections teams spend enormous time as "email detectives," piecing together whether messages were received and what follow-up is needed. Full-stack AI handles that investigation automatically and executes the outreach without waiting for a human to queue each task.
Why B2B Collections Require Custom Tools
Generic CRM or billing platforms are not built for B2B complexity because B2B transactions carry complexity consumer billing software never encounters. A single manufacturer may invoice the same customer across multiple purchase orders, ship-to addresses, billing entities, and payment terms within one billing cycle.
Corporate structures where subsidiaries pay on behalf of parents create matching problems generic tools cannot handle reliably. B2B also involves customer-managed portals like Ariba, Coupa, and Tungsten, plus deduction practices where customers routinely pay less than the invoice total due to early-pay discounts, damaged goods claims, or trade promotions. For manufacturing and distribution companies, these are standard operating conditions.
Beyond Spreadsheets: Automating AR Collections
Overcoming Industry-Specific AR Hurdles
Manufacturing companies carry an average DSO of 52 days with a typical range of 40 to 65 days, according to CreditPulse's 2025 benchmark data. Wholesale and distribution firms average 38 days with a typical range of 28 to 50 days. Every additional day of DSO represents cash trapped in receivables that could fund inventory, cover payroll, or support growth.
For example, a company generating $100 million in annual credit sales and carrying 55 days DSO has roughly $15 million tied up in receivables. Reducing DSO to 35 days, achievable through full-stack AI automation based on live customer results, frees approximately $5.5 million in working capital, enough to fund an entire production run for margin-constrained manufacturers.
The Collection Effectiveness Index (CEI) measures what percentage of receivables a company collects in a given period relative to what was collectible. Stuut's DSO improvement framework places 80% or above as a strong CEI score, with best-in-class organizations reaching 90% or above.
Navigating Supply Chain Payment Hurdles
Manufacturing and distribution supply chains generate disputes at every stage: shipping delays, damaged goods, short-pays tied to freight charges, and proof-of-delivery disagreements. Each dispute freezes the related invoice while both teams investigate manually, often over email chains that span weeks. Without automated categorization and routing, disputes can age significantly before escalation.
Why Manual Collections Drain AR Budgets
AR specialists spending most of their day on routine outreach, invoice resends, and payment matching have limited capacity for credit risk analysis or strategic account management. As Stuut's DSO improvement framework reports, Stuut customers achieve an average 37% DSO reduction. That compression doesn't come from adding staff: It comes from eliminating the administrative overhead that slows every collection cycle.
Signs an Organization Needs AR Automation
AR Directors can self-assess where manual processes create the most drag using the following questions:
- Portal logging: Does the AR team manually log into customer portals to upload invoices multiple times per week?
- Unapplied cash: Do payments sit in the suspense account without being matched to an invoice, creating reconciliation backlogs?
- Coverage gaps: Do smaller-balance accounts go uncontacted because the team lacks capacity?
- Close delays: Does month-end close run late because of manual payment matching backlogs?
- Spreadsheet dependency: Does the team track customer payment promises in personal spreadsheets that live outside the ERP?
Must-Have Capabilities for AR Management Software
Automating Routine Dunning and Follow-Ups
Effective AR automation monitors invoice due dates and contacts customers before invoices go overdue. Stuut sends reminders across email, SMS, and AI-powered voice, selecting the channel based on each customer's communication history. A customer who responds to SMS reminders consistently gets an SMS next time, not an email that routes to spam.
The AI-powered voice calling capability is a significant differentiator for industrial customers where phone-based collections remain standard practice. Stuut's call agent conducts real conversations, confirming payment timing, answering balance questions, and sending a payment link on request, all with full contextual knowledge of the customer's open invoices, payment history, and prior communications.
Legacy platforms like HighRadius and Billtrust offer assisted dialing and call transcription for human collectors, which is a different function entirely. Assisted dialing means a human collector still runs the call while software logs it. Stuut's agent conducts the call autonomously, and that distinction determines whether collections coverage scales with headcount or scales automatically.
Payment Matching and Cash Application
A 95%+ automated cash application rate requires the system to handle scenarios far beyond simple one-to-one matches. Stuut's three-way matching algorithm cross-references invoice numbers, customer identifiers, and payment amounts, parsing remittance data from bank accounts, lockboxes, and digital payment rails to handle exact matches, partial payments, overpayments, and multi-invoice wires. For bulk deposits where a single Stripe transaction covers 100 individual customer payments, Stuut breaks the deposit into sub-payments and matches each one.
When Stuut can't match a payment with sufficient confidence, it contacts the customer automatically to request remittance details rather than routing the exception to a human queue.
Automating Customer Portal Invoice Uploads
Manual portal submissions to Ariba, Coupa, and Tungsten consume significant AR team capacity each week. Collectors log into each portal separately, navigate different interfaces, and manually enter invoice data that already exists in the ERP. Stuut automates these submissions, eliminating the portal-login loop that AR teams cite as one of their most time-consuming daily tasks.
Handling Deductions and Disputed Invoices
Stuut automatically creates a dispute case when a customer contests an invoice, categorizes the dispute by reason code, attaches supporting documentation, and routes it to the appropriate internal team, whether that's sales, shipping, or finance. Stuut resolves disputes 9x faster than manual processes. For CPG-specific deductions tied to trade promotions, damaged goods, or retailer chargebacks, Stuut pulls backup documentation, validates claims against agreements, and files recovery claims on invalid deductions that would otherwise be written off.
ERP Sync for AR Teams
Controllers evaluating AR automation need assurance that the platform maintains audit-ready processes. Stuut connects to SAP, Oracle, NetSuite, and Microsoft Dynamics via API credentials without modifying the ERP configuration. Reasoning and customer outreach use probabilistic AI, while every cash application entry, payment posting, and ledger write remains deterministic: confidence-scored, reconcilable to the ERP, and logged for audit. The agent escalates below its confidence threshold rather than writing automatically.
On the security side, Stuut double-encrypts customer PII through a partnership with Skyflow, which isolates sensitive data in a privacy vault where downstream databases store only token representations, removing them from compliance scope. Stuut is SOC 2 certified and GDPR compliant, with ISO 27001 and HIPAA compliance in progress.
Controllers should verify three things before approving any AR platform: The platform pulls data in real time, encrypts PII at rest, and maintains a complete audit trail.
Tracking the Team's Collection Results
Reporting requirements go beyond aging trend visualization. Finance leadership needs real-time CEI tracking, automated outreach performance by channel and customer segment, and account-level timelines that surface which customers are trending toward escalation before they hit 60-day aging. Stuut's dashboard surfaces all customer interactions in real time, giving the AR Director full visibility without requiring manual status updates from the collections team.
How AR Collections Automation Works in Practice
How AI Handles Daily Dunning
When Stuut detects an invoice approaching its due date, it checks the customer's payment history to determine the right channel and message cadence. For example, a customer who consistently pays on the 15th after two reminders receives those reminders on the cadence that matches their pattern. A customer whose history shows a preference for SMS gets an SMS with a digital payment link rather than an email that routes to spam. The agent logs every interaction, updates the ERP in real time, and queues the next action based on the customer's response.
Defining Roles for AI and Collectors
The division of labor is clear: The AI handles the majority of routine outreach and payment matching for managed accounts, while human collectors step in when the AI escalates a complex dispute, a payment plan negotiation, or a relationship that requires judgment beyond the system's confidence threshold. As Stuut's Versapay comparison illustrates, software-first platforms require human collectors to execute every task the platform organizes, whereas full-stack AI executes the workflows end-to-end.
Focusing on Strategic Accounts
AR teams freed from routine dunning shift to work that requires institutional knowledge: payment plan negotiations with high-value accounts, complex deduction research, and credit risk analysis. Razvan Bratu, Head of Quote to Cash at Honeywell, describes this shift directly:
"We're collecting faster from the in-scope customers, our cash flow is improving, and our team has more time to focus on white gloves service for top customers. The platform handles the routine work so our people drive increased real business value." - Razvan Bratu, Head of Quote to Cash, Honeywell

The shift moves AR specialists from spending the majority of their day on repetitive tasks to spending the majority of their day on work that requires specific expertise and relationships.
Planning the AR Automation Rollout
For IT and Controllers: Mapping AR Tools to the ERP
IT leaders and Controllers evaluating AR automation should verify the following before committing to any platform:
- ERP connectivity: Confirm the platform connects via API credentials to SAP, Oracle, NetSuite, or Microsoft Dynamics without middleware development.
- No ERP modification: Verify that no chart-of-accounts changes, custom coding, or data migration are required.
- Data mapping scope: Confirm what the platform maps during setup, covering invoice records, customer master data, payment terms, and transaction history.
- Write-back controls: Confirm that every GL posting is confidence-scored and that exceptions escalate to humans rather than writing automatically when confidence drops below the defined threshold.
- Audit trail: Confirm that every AI action, outreach event, and payment posting logs to an audit-ready record reconcilable to the ERP.
For Stuut, IT provisions API credentials with read/write access in the ERP, which takes a few hours, with no additional development steps required. The HighRadius integration complexity analysis details why legacy platforms require significantly more IT involvement because their rules engines require every exception path to be configured before go-live.
Data Migration and Setup Timeline
Legacy AR platforms require every dunning sequence, approval hierarchy, and matching rule to be encoded before go-live, which is why implementations take 3 to 6 months for rules-based platforms. Full-stack AI infers the correct action from data patterns and policies, handling cases no one configured in advance, so going live means connecting to the ERP rather than authoring every behavior upfront. Stuut's standard onboarding completes in 3 to 4 days for SAP, Oracle, NetSuite, and Dynamics environments, with full go-live and first autonomous outreach within 6 to 10 days.
How to Build Internal Buy-In for AR Tools
The CFO presentation focuses on working capital impact: DSO reduction, freed cash, and collections coverage that scales without adding headcount. The IT presentation focuses on resource requirements: provisioning API credentials takes a few hours, no middleware development follows, and the ERP configuration stays untouched. The AR team presentation requires a different approach, covered in the change management section below.
Phased Rollout vs. Full Implementation
Starting on long-tail accounts, specifically the accounts the AR team currently lacks capacity to reach, builds trust and demonstrates value without disrupting top-tier customer relationships. Bishop Lifting deployed across 45 branches over a 6-week go-live, automating 91% of outbound communications and achieving a 35% reduction in overdue receivables alongside a $3 million working capital improvement.
Strategies for Managing Team Change Anxiety
Protecting the Collector's Role During Transition
The dominant concern for collections specialists is whether AI will take their jobs, and it deserves a direct answer from the AR Director. These talking points work:
- Stuut is designed to take over routine work so specialists spend time on accounts that need judgment, not on invoice resends and portal logins.
- The AI handles the first three touches on routine accounts. Human specialists handle the accounts that actually need a human: disputes, payment plans, and high-value relationships.
- Hundreds of accounts currently go uncontacted because the team lacks capacity. Stuut covers those accounts, so the existing portfolio remains with the team.
Prioritizing Complex Account Disputes
Collectors who transition to dispute resolution specialists bring institutional knowledge that no AI can replicate: knowing which sales rep quotes incorrect pricing, which shipping partner generates damaged-goods claims, and which AP contacts actually have authority to release payment holds. Stuut's dispute routing puts that knowledge to work on complex cases.
New Priorities for Modern AR Analysts
The transition from routine dunning to strategic collections management shifts the role toward higher-value work. AR analysts who implement and run AI-powered collections are positioned as forward-thinking financial operators. Managing credit risk, analyzing payment trends, and advising on customer-specific payment terms are skills that strengthen a finance career and deliver measurable value to the business, measured in DSO reduction, CEI improvement, and working capital freed.
Building Trust in AI-Generated Communications
Collectors who have spent years building communication tone and relationship history with specific accounts reasonably worry that AI will damage those relationships. Stuut addresses this through built-in oversight controls that give AR teams visibility into AI-generated communications and the ability to intervene on sensitive customer relationships. Collectors who rarely use the override report that knowing it exists builds the confidence to trust the AI's routine outreach.
Measuring AR Automation Results
Projecting DSO Drops with Automation
CFOs building a business case for AR automation can calculate freed working capital using this formula:
Freed Capital = (Current DSO - Target DSO) x (Annual Credit Sales / 365)
Example: A company with $150 million in annual credit sales and 55 days current DSO targeting 35 days frees 20 days x $411,000 per day = $8.2 million in working capital freed from receivables.
Benchmark: Stuut customers report an average 37% DSO reduction across live deployments.
PerkinElmer's deployment reduced overdue invoices from 50% to 15% in one year and unlocked $300 million in cash flow that funded two acquisitions.
Measuring Productivity Gains per User
Efficiency gains are measurable at the account level. Bishop Lifting's AR team managed 50% more accounts per employee after Stuut's deployment across 45 branches without adding headcount. EZG Manufacturing logged 1,597 automated touchpoints across email and voice, collected $11.67 million, reduced DSO by 5 days, and saved approximately 20 hours of weekly AR team time, all while 95% of outreach was automated.
Embedded Payment Rails
Adding digital payment rails directly into automated communications removes friction that delays payment for customers willing to pay but facing process barriers. Stuut integrates credit card and ACH payment links through Stripe, generating and sending a payment link mid-conversation when a customer expresses intent to pay during a voice call or email exchange, eliminating manual payment processing steps.
Automating Follow-Ups for Small Balances
Smaller-balance accounts represent trapped cash that human collectors rarely have time to contact. Action Elevator worked hundreds of sub-$300-per-month accounts consistently after deployment, collecting $4.3 million on Stuut-touched invoices in four months while Stuut made 1,822 calls on the team's behalf. Ally Logistics reduced its overdue percentage from 26% to 11% in two months, collecting over $1.8 million in 3.5 months from accounts the team previously couldn't reach.

Platform Comparison: Legacy vs. Full-Stack AI
Table 1: Software-First AR Platforms
Dimension HighRadius Billtrust Tesorio Architecture Software-first, AI layered on Software-first, AI layered on Software-first, AI layered on Implementation 3-6 months 3-6 months Under 30 days Primary market Fortune 500 Mid-market to enterprise Mid-market Key strength Module breadth Invoice delivery Ease of use Pricing model High subscription + professional services Subscription + professional services Subscription Founded 2006 2001 2015
Table 2: Full-Stack AI vs. Software-First
Dimension Stuut Versapay Architecture Full-stack AI, built for autonomous execution Software-first, AI layered on Implementation 3-4 day onboarding, 6-10 day go-live Varies Primary market Mid-market and enterprise Mid-market Key strength Autonomous execution NetSuite integration Pricing model Per-agent, no implementation or professional services fees Custom contract Founded 2024 2006
HighRadius holds enterprise market position through its tenure in market and recognized breadth of product capabilities, not through architecture. Billtrust excels at invoice delivery infrastructure, and Stuut's full-stack AI covers the same customer communication workflows autonomously. Tesorio and Versapay deliver clean user experiences, and Stuut adds autonomous execution on top of that usability: AR teams review what the AI does rather than doing it themselves.
Pricing and Total Cost of Ownership
Understanding AR Software Pricing Models
Legacy AR platforms typically combine a base subscription with implementation fees, professional services for configuration, and ongoing support contracts. HighRadius and Billtrust implementations frequently involve six-figure professional services engagements before a single invoice is touched autonomously, because every dunning rule, exception path, and matching configuration must be authored by implementation consultants before go-live.
Stuut uses a per-agent pricing model with no implementation fees, no professional services fees, and no middleware development costs. IT provisioning takes a few hours rather than months of consultant time. The total cost of ownership comparison therefore extends beyond the subscription line: Legacy platforms carry a meaningful implementation cost that does not appear in the per-seat or per-module quote.
TCO Factors to Evaluate
CFOs and Controllers should account for the following when comparing AR automation platforms:
- Implementation fees: Confirm whether professional services, consulting, or custom integration work is included or billed separately.
- IT resource cost: Estimate internal hours required for ERP configuration, middleware development, and ongoing rule maintenance. Legacy platforms require significantly more IT involvement than API-credential-based platforms.
- Time to value: A platform that goes live in 6 to 10 days begins generating DSO improvement and cash flow impact months before a platform that takes 3 to 6 months to implement.
- Headcount assumptions: Software-first platforms that organize work for human collectors to execute do not reduce the headcount required to run the portfolio. Full-stack AI that executes outreach autonomously scales coverage without adding staff.
- Ongoing rule maintenance: Deterministic platforms require manual rule updates when business conditions change. AI-native platforms infer new patterns from data without reconfiguration.
Stuut's per-agent model is designed so that the cost scales with the work being automated, not with the number of modules licensed. Finance teams can book a demo to receive a TCO comparison specific to their ERP environment and account portfolio size.

Key Terms Glossary
Days Sales Outstanding (DSO): The average number of days it takes a company to collect payment after a sale, calculated as accounts receivable divided by average daily credit sales. Manufacturing DSO benchmarks range from 40 to 65 days.
Cash application: The process of matching incoming customer payments to corresponding open invoices in the ERP AR subledger. Manual cash application can delay month-end close.
Remittance advice: A document sent by a buyer to a seller confirming that an invoice has been paid, often detailing partial payments, deductions, or invoice-level allocation across a bulk deposit.
Deduction: A practice where a customer pays less than the full invoice amount due to disputes, damaged goods, early-payment discounts, or trade promotions. Deductions require categorization, validation, and in some cases recovery claim filing.
Deterministic architecture: A rules-based software system that executes only pre-configured paths. Every dunning sequence, exception, and matching rule must be encoded before go-live, making implementation timelines run in months.
Probabilistic architecture: An AI-native system that infers the correct action from data patterns and policies, handling cases no one configured in advance. Going live requires connecting to the ERP rather than authoring every behavior upfront.
Collection Effectiveness Index (CEI): A metric measuring what percentage of receivables a company collects in a given period relative to total collectible receivables. A CEI of 80% or above is considered strong, with best-in-class organizations reaching 90% or above.
Aging buckets: Categories of outstanding receivables segmented by time outstanding: 0-30 days, 31-60 days, 61-90 days, and 90+ days. Accounts in the 61-90 and 90+ buckets carry the highest write-off risk.
