Best Accounts Receivable Automation Software in 2026: 15 Platforms to Cut DSO

Updated August 2026

The best accounts receivable automation platform in 2026 depends less on brand recognition than on which job you need done. HighRadius, Billtrust, Esker and Sidetrade lead for AI-driven cash application and credit risk scoring wired into SAP, Oracle or another large ERP. Chaser, Gaviti, Upflow, Invoiced, Versapay, Tesorio, Peakflo and Growfin fit mid-market collections workflow: chasing invoices, logging disputes and applying cash without hiring three more collectors. BILL leads for smaller teams that want AP and AR under one login. Rework fits a narrower case: mid-size companies that want income operations sitting on the same platform and customer record as their CRM, invoicing and bank reconciliation, not a dedicated AR point tool.

This guide ranks 15 platforms for CFOs, VPs of Finance, controllers, and credit and collections managers at companies roughly 50 to 5,000 employees, weighted toward who owns invoice delivery, collections outreach, cash application, credit management and the customer payment portal. Most of this category doesn't publish pricing, so where a vendor names a figure, this guide states it with the source, and where nothing is published, it says so instead of dressing up a third-party guess. What actually drives a quote is invoice volume, entity count, ERP scope, module mix and user count, not seats alone. If your real question is how to bill customers rather than collect once invoiced, the sibling subscription billing software guide covers that upstream decision: billing creates the invoice, AR automation is what happens after. Every price below was checked against the vendor's own page in August 2026.

Which Segment Are You Actually In?

Pick a row before you pick a vendor. A 150-person company comparing HighRadius against Chaser is comparing apples to a much bigger orange: HighRadius fits multi-entity, multi-ERP organizations with dedicated credit teams, while Chaser fits a two- or three-person collections function that needs invoices chased consistently, not credit scoring.

Sizing and Persona Table

1. HighRadius: Autonomous Receivables at Enterprise Scale

HighRadius built its position around Autonomous Receivables, an AI suite spanning cash application, credit management, collections prioritization, deduction management and cash forecasting on one data model, for organizations processing thousands of invoices a month across multiple entities and ERPs. It has raised roughly $484 million, last valued at $3.1 billion in a 2021 Series C, and remains private with no new round since. HighRadius doesn't publish pricing, stating only that it's subscription-based and pay-as-you-go. For teams on NetSuite, integration depth is the real differentiator.

If HighRadius is the incumbent you are pricing against, the HighRadius alternatives guide compares the rest of this field on cost, fit and depth.

Pricing: No published price, pay-as-you-go, quoted on invoice volume and ERP scope. Best for: Enterprises with high invoice volume across multiple entities or ERPs. Not ideal for: Teams under roughly 500 employees, where implementation weight outweighs the depth.

---

2. Billtrust: Enterprise Invoice-to-Cash Since Before the Category Had a Name

Billtrust's core strength is cash application: matching incoming payments to open invoices automatically, including the messy remittance formats (paper checks, lockbox scans, EDI files) still common at large organizations, alongside credit decisioning, collections and a B2B payments network, aimed at manufacturing, distribution and healthcare finance teams. EQT completed a $1.7 billion take-private acquisition in December 2022, and Billtrust's stock left Nasdaq that month, so unlike still-public Sidetrade or Esker it no longer files disclosures buyers could once check independently. Pricing isn't published; every deal is quoted on invoice volume and modules.

Pricing: No published price, quote only. Best for: Large organizations with high-volume, high-friction remittance formats. Not ideal for: Smaller teams without the invoice volume for an enterprise sales cycle.

---

3. Versapay: Collaborative AR for Sage and Acumatica Shops

Versapay's differentiator is the customer-facing side: a payment portal and "collaborative AR" model where a customer with a billing dispute resolves it in the portal instead of an email thread with your AR team. Cash application deepened through its 2021 DadeSystems acquisition, and the platform integrates most tightly with Sage Intacct, Sage 300/500, Acumatica and NetSuite. Great Hill Partners has owned Versapay since 2020; pricing isn't published, and every deal is quoted on invoice volume and ERP integration. For a team standardized on Sage Intacct, that native fit is the practical argument over a generic AR tool.

Pricing: No published price, quote only. Best for: Mid-market teams on Sage, Acumatica or NetSuite wanting a payment portal. Not ideal for: Companies on a different ERP entirely.

---

4. BILL: Accounts Payable and Receivable Under One Login

BILL, formerly branded Bill.com before an October 2022 rebrand, is the common answer for a smaller finance team wanting bill pay and invoicing or collections in one system rather than two. It's publicly traded (NYSE: BILL) and widely used by accounting firms. Published pricing, per user per month: Essentials $49 (AP and AR), Team $65, Corporate $89 (adds Procurement), Enterprise custom; Spend & Expense is a separate $0-per-user product. For a fuller comparison against its AP-side competitors, see the BILL alternatives roundup.

Pricing: Essentials $49/user/month, Team $65, Corporate $89, Enterprise custom. Best for: SMB and lower mid-market teams wanting AP and AR under one login. Not ideal for: Teams needing deep AR-only functionality like credit scoring.

---

5. Quadient AR: Predictive Collections

Quadient AR, known as YayPay before Quadient's 2020 acquisition folded it into its own brand, focuses on predictive collections prioritization: ranking which accounts to chase first by payment history and risk signals, alongside credit risk dashboards, dunning workflows and a customer portal, aimed at teams processing roughly 500-plus invoices a month. It doesn't publish pricing; its site says only that cost "varies based on business size, process complexity, and required features." As part of a broader document and mail-services company, it carries less of a pure-play AR focus than Versapay or Chaser.

Pricing: No published price, quote only. Best for: Mid-market B2B teams processing several hundred invoices a month. Not ideal for: Very small teams with low invoice volume.

---

6. Rework: Income Operations on the Same Record as the Deal

Rework's Incomes module, alongside its Invoice and Bankfeeds modules, lives inside the same platform as its CRM/Sales, Lead Management, Contract and Work Ops apps, so an invoice tied to a deal shares the account record as the pipeline that created it, instead of syncing between a CRM, a billing tool and a separate AR platform. The pitch isn't collections AI at HighRadius depth; it's that income operations, invoicing and reconciliation shouldn't live in three logins that quietly drift apart.

Pricing: No published price for Incomes; Rework sells packaged plans, not per-user or per-invoice licenses, quoted per organization. See rework.com/pricing. Best for: Mid-size teams (20 to 200 people) wanting income ops on the same platform as the CRM pipeline. See Best CRM Software for how Sales Ops compares to Salesforce and HubSpot. Not ideal for: Enterprise cash application and credit scoring at HighRadius scale, or a solo operator (minimum package is 5 users).

---

7. Invoiced: API-First AR for Dev-Friendly Finance Teams

Invoiced, an Austin-based platform operating since roughly 2013, built its pitch around a flexible API and workflow builder rather than a fixed process, bundling invoicing, dunning sequences, a payment portal and subscription billing in one product for teams that want to wire it into a custom workflow rather than adapt to defaults. It doesn't publish pricing; the site offers a demo request only, and it carries less brand recognition than HighRadius, Billtrust or Esker, though the API-first design is a genuine differentiator for teams with engineering resources.

Pricing: No published price, demo only. Best for: Mid-market teams with engineering resources wanting a custom API-built workflow. Not ideal for: Teams wanting a fully pre-built workflow out of the box.

---

8. Chaser: Relationship-Preserving Collections, Not a Platform Overhaul

Chaser, a UK-based platform, solves one problem: getting invoices chased consistently without sounding like a collections agency. Its sequences run across email, SMS and letters, tuned to stay professional rather than aggressive, layered on top of QuickBooks, Xero, Sage or NetSuite instead of replacing the accounting system underneath. Published pricing (also in GBP, EUR, AUD, NZD): Compact $259/mo ($233 annual) for 4 users, Core $779/mo ($700 annual) unlimited users, Complete $1,169/mo ($1,050 annual), custom above; Chaser Care is a separate add-on.

Pricing: Compact $259/mo ($233 annual), Core $779/mo ($700 annual), Complete $1,169/mo ($1,050 annual), custom above. Best for: SMB and mid-market teams wanting invoices chased consistently, no migration. Not ideal for: Teams needing cash application, credit scoring or deduction management.

---

9. Upflow: Collections Visibility With a Free Analytics Tier

Upflow's pitch is visibility: payment-behavior analytics and benchmarking alongside collections and dunning workflow, integrated with QuickBooks, Xero, NetSuite and Stripe. Its Discover tier is genuinely free forever, limited to analytics rather than full workflow. The paid tiers, Grow (under $10M ARR), Scale ($10M-$50M ARR) and Strategic ($50M-plus ARR), are all quote-only, an ARR-banded structure that signals Upflow prices to company scale rather than user count alone.

Pricing: Discover free forever (analytics only); Grow, Scale, Strategic tiers quote-only. Best for: Finance leaders wanting payment-behavior visibility, valuing a free tier to start. Not ideal for: Teams needing full automation immediately without a sales call.

---

10. Gaviti: Collections Task Automation Without Hiring More Collectors

Gaviti automates the repetitive parts of a collections week (task assignment, follow-up scheduling, aging reports, dunning) so a small team can manage growing invoice volume without adding headcount, rounded out by a credit management module and configurable dashboards for teams standardizing a process that used to run on spreadsheets. It doesn't publish pricing; its site states pricing is "tailored based on your usage, not per user," a genuinely different model, though it leaves no published number to anchor a budget conversation.

Pricing: No published price, usage-based quote. Best for: Collections teams wanting task automation as invoice volume grows. Not ideal for: Teams needing a published price to budget upfront.

---

11. Esker: AP and AR on One Platform, One Data Model

Esker, a French software company founded in 1985 and still publicly traded, runs both procure-to-pay and order-to-cash on one platform and data model, giving finance working-capital visibility from both directions at once. Esker Synergy AI, its embedded agent layer, handles extraction, matching and workflow across both sides, and Esker has been named a Leader in Gartner's Magic Quadrants for Invoice-to-Cash and Accounts Payable Applications, plus Forrester's Wave for AP Invoice Automation. None of that comes with a published price: every deal is quoted on volume and modules.

Pricing: No published price, quote only based on volume and modules. Best for: Enterprises wanting AP and AR on one platform instead of two tools. Not ideal for: Teams needing only AR with no interest in consolidating AP.

---

12. Tesorio: Collections Tied Directly to Cash Flow Forecasting

Tesorio ties AI-driven collections prioritization directly to a live cash flow forecast, so a finance team can see how chasing a specific account moves the forecast, not just the aging report, a fit for teams evaluating AR alongside a broader forecasting decision like the sibling FP&A software guide. It doesn't publish pricing; its site directs every prospect to "Speak With a Human" rather than a pricing page, and as a smaller vendor than HighRadius or Billtrust it carries thinner analyst coverage.

Pricing: No published price, contact sales. Best for: Teams wanting collections prioritization tied to cash flow forecasting. Not ideal for: Teams needing straightforward chasing without a forecasting layer.

---

13. Sidetrade: AI-Native Scoring Built on a B2B Payment Data Network

Sidetrade, publicly traded on Euronext Paris (ticker ALBFR), built its platform, Sidetrade Augmented Cash, around a genuine network effect: predictive credit scoring and collections prioritization trained on B2B payment behavior data aggregated across its customer base, not just one company's own history, differentiating it from competitors whose AI only sees a single customer's data. It doesn't publish pricing, with deals quoted per organization on invoice and revenue scope; being publicly traded is a real advantage, since unlike Billtrust or HighRadius its financials are independently checkable through filings.

Pricing: No published price, quoted per organization on invoice and revenue scope. Best for: Enterprises wanting credit scoring that benefits from a wide payment-data network. Not ideal for: Small teams without the invoice volume for an enterprise AR platform.

---

14. Peakflo: Agentic AI Across Both AP and AR

Peakflo, a Singapore-based company founded in 2021, builds agentic AI agents that handle both AP and AR workflows: invoice matching, payment approvals and reconciliation on the AP side, collections follow-ups and cash application on the AR side, backed by Y Combinator among other early-stage investors. It doesn't publish pricing, framing cost as built around each company's "agentic workflow" and directing prospects to book a call. Its customer base and track record are concentrated mostly in Southeast Asia so far.

Pricing: No published price, custom quote based on workflow. Best for: Fast-growing mid-market companies wanting AI agents across AP and AR. Not ideal for: Buyers wanting an established, multi-year track record first.

---

15. Growfin: Collections Tied to CRM Deal Context

Growfin built its platform for B2B SaaS and subscription finance teams, where the person chasing an overdue invoice benefits from seeing the same deal and account context a sales or customer success rep sees in HubSpot or Salesforce, not just an isolated invoice line. It raised a $7.5 million Series A led by Singapore's SWC Global (roughly $9 million total funding), and the company states its customers have collected more than $1 billion in receivables through the platform. Pricing isn't published; the site directs prospects to book a demo.

Pricing: No published price, demo only. Best for: B2B SaaS teams wanting collections tied to CRM context. Not ideal for: Non-subscription businesses without recurring CRM deal data.

Platform Buying Mistakes to Avoid

How to Choose: Decision Framework

The right accounts receivable system depends on collections volume, ERP expectations, and whether finance needs a narrow AR tool or a broader operational platform.

What to Do Next

Pick two platforms from opposite ends of this list, one that matches your invoice volume and ERP setup today, one built for the scale you'd grow into, and run the same three tests on both before a contract reaches legal.

First, connect a real batch of your own invoices, not demo data, and watch how much manual cleanup cash application still requires. Second, log in as a customer and test the payment portal end to end. Third, get every cost in writing, including implementation, since almost nothing here publishes a number upfront.

If the shortlist still feels wide, decide whether the actual gap is cash application accuracy, credit risk scoring, collections workflow or platform consolidation, since one tool rarely wins at all four.
