HighRadius and Billtrust are both established accounts receivable (AR) platforms, each with its own loyal customer base. However, if you're evaluating AR automation, you're wondering, "HighRadius vs. Billtrust: which is better?"

Each platform approaches receivables differently and serves distinct market segments. While both serve their purpose well, there’s a better alternative in Lunos.

Why Trust Us?

Lunos was founded after decades of frustration with B2B payment bottlenecks. Accounts receivable is a communication and negotiation problem, not just a payment one. 

That gap costs companies millions. 

We’ve worked with finance teams handling anywhere from 500 to 50,000 invoices per month and understand what real automation looks like. Too many AR platforms automate reminders but still rely on constant manual follow-up. This HighRadius vs Billtrust comparison is based on what truly reduces workload instead of shifting it.

HighRadius vs. Billtrust: A Brief Overview

What is HighRadius?

HighRadius is an enterprise-grade AR automation platform that offers a suite of 18+ AI agents that help with tasks spanning collections, credit management, and cash application. With 18+ modules available, it can handle scale, complexity, and high transaction volumes across global operations.

HighRadius also automates credit risk assessments and approvals. This enables faster and more accurate credit decisions. It's a great platform for reducing manual reviews and exposure to bad debt. Combined with advanced cash application automation, it supports end-to-end order-to-cash workflows across multiple systems, regions, and currencies. 

  • Best for: Large enterprises with high invoice volumes (5,000+ monthly) that need automated cash application and structured collections workflows.
  • Pricing: Custom pricing typically starts around $50,000-$150,000+ annually, depending on modules and invoice volume.
  • Key strengths: Powerful cash application automation, enterprise-grade scalability, and a comprehensive AR suite including credit and deductions management.
  • Main drawbacks: Long implementation timelines (6-12 months), requires dedicated IT resources, rules-based automation still needs manual intervention for customer responses, and is expensive for mid-market companies.

Overall, HighRadius is a comprehensive but complex platform designed for enterprises with the budget and resources to manage lengthy implementations and ongoing configuration.

What is Billtrust?

Billtrust is an AR automation and digital payments platform focused on invoice delivery, payment processing, and cash application. It functions primarily as invoice-to-cash software, focusing on invoice delivery, payment portals, and cash application.

The platform aims to reduce DSO by making it easier for customers to view and pay invoices. Billtrust is popular for improving the payment experience, but it focuses less on collections strategy. Finance teams still have to handle follow-ups, dispute conversations, and payment promises manually.

  • Best for: Mid-market to enterprise B2B companies that want to digitize invoice delivery and create self-service payment portals.
  • Pricing: Custom pricing typically starts around $20,000-$60,000+ annually, depending on invoice volume and modules.
  • Key strengths: Strong payment portal functionality, automated invoice delivery, reduces manual payment processing, and good cash application capabilities.
  • Main drawbacks: Focuses on payment infrastructure rather than collections conversations and has limited intelligence for handling customer communications. 

Billtrust excels at the payment infrastructure side of AR but leaves the collections, communication, and follow-up workflow largely manual.

With that out of the way, let's dive into some of the more prominent differences:

1. Pricing and Total Cost of Ownership

The pricing structure is one of the most significant differences between these platforms.

HighRadius

Pricing is based on invoice volume, users, and modules. Implementation fees are also part of the package and can cost $50,000–$150,000+, with high annual licensing fees. Ongoing IT involvement is required for integrations and maintenance, adding high hidden costs beyond the base software price.

Billtrust

While pricing information isn’t publicly listed, third-party review sites and users report prices ranging from $20,000 to $60,000 annually. However, costs increase significantly based on invoice volume and payment processing fees. Transaction fees for payment processing can add unexpected costs as volume grows.

What to choose:

  • HighRadius: For large enterprises with budgets exceeding $100,000 annually and dedicated IT teams
  • Billtrust: For mid-market B2B companies focused on digitizing invoice delivery and payment collection

2. Implementation Complexity and Time to Value

Time to value is another crucial factor to consider when evaluating any B2B tool. 

HighRadius

HighRadius implementations often take 6–12 months and require heavy IT involvement, complex integrations, data migration, and user training. Finance teams keep running manual processes while paying for software they can’t fully use. HighRadius has quite a steep learning curve and often needs ongoing technical configuration to maintain.

Billtrust

Billtrust implementations are faster than HighRadius at 3–6 months. However, it still requires significant setup, including system integrations, portal configuration, and customer onboarding. While less complex than HighRadius, technical resources and planning are still required. Finance teams often run manual processes in parallel during the transition, delaying full time-to-value.

What to choose:

  • HighRadius: For enterprises that can commit to 6-12 month implementations with dedicated teams
  • Billtrust: For mid-market companies wanting faster time to value with moderate complexity

3. Collections Automation and Customer Communication

Most AR automation software still relies on rules and templates rather than understanding customer intent. This is where the fundamental difference between traditional AR automation and modern AI solutions becomes clear. In the HighRadius vs. Billtrust battle, which platform takes the lead?

HighRadius

HighRadius automates collections with AI-driven prioritization, workflows, templates, and scheduled reminders. You can set up outreach sequences, worklists, and tasks based on factors like aging, risk, and payment behavior. While it reduces manual effort for structured follow-ups, disputes, and promise-to-pay tracking, it isn’t fully conversational. In some cases, it still requires finance teams to review and determine next steps, as the system cannot interpret intent or generate adaptive responses.

Billtrust

Billtrust focuses more on payment infrastructure than on collections communication. The platform sends automated invoice delivery and payment reminders but offers limited capabilities for managing ongoing customer conversations about overdue balances.

Finance teams still need to manually chase payments, respond to customer questions, and track payment promises outside the system. Billtrust makes paying easier, but doesn't eliminate the collections workload.

What to choose:

  • HighRadius: For enterprises needing structured workflows for large collections teams
  • Billtrust: For companies where payment friction is the main issue, not collections conversations

4. Cash Application and Payment Processing

Both platforms excel at different aspects of the payment-to-cash cycle.

HighRadius

HighRadius uses machine learning to automate cash applications, matching payments to invoices across millions of transactions. It handles complex scenarios, partial payments, and multi-invoice remittances, saving time and improving accuracy. However, its payment processing features are basic compared to specialized payment platforms.

Billtrust

Billtrust excels at payment processing with customer portals, multiple payment methods, and easy online payments. It streamlines cash collection, making it simple for customers to pay. While effective for straightforward transactions, it isn’t as advanced as HighRadius for complex payment matching or processing large volumes of complicated remittances.

What to choose:

  • HighRadius: For enterprises with complex cash application needs across high payment volumes
  • Billtrust: For companies where payment friction and customer portal experience are priorities

5. Reporting and Analytics

Both platforms offer analytics, but they focus on different parts of accounts receivable. 

HighRadius

HighRadius provides detailed reports on key AR metrics, including DSO, aging, collector performance, and cash forecasts. These reports cover the entire accounts receivable process.

However, setting up and using these reports can be complex and often requires technical knowledge. The interface often feels overwhelming for managers who just want quick, easy insights without the extra effort required to set up.

Billtrust

Billtrust focuses its reporting on payment activity, portal usage, and invoice delivery performance. These insights help teams see which customers are using digital payments and where issues slow down the payment process.

However, reporting on collections performance and customer communication is more limited than with HighRadius. Billtrust tracks how well payments flow through the system more than how effective collections efforts are.

What to choose:

  • HighRadius: For comprehensive AR analytics across the full receivables function
  • Billtrust: For payment and portal adoption analytics
