ABA Billing Software Comparison: CentralReach vs. Motivity vs. AlohaABA vs. RethinkBH

Updated June 2026. Competitor details are sourced and linked; confirm current vendor specifics before relying on them for a purchase decision.

ABA billing is one of the most operationally complex functions a practice manages, and one of the most consequential. Authorization units, overlapping service codes, electronic visit verification, multi-state payer rules, and frequent funder changes sit on top of every claim, and the team responsible for collecting that revenue is often the same team absorbing high turnover. Industry estimates put initial healthcare claim denial rates in the range of 15% to 30%, with reworking those claims consuming a meaningful share of staff time each month. [11] Choosing the right ABA billing software is less about feature counts and more about which system keeps claims moving, catches problems before they become denials, and fits the way your practice actually operates.

This guide compares four platforms ABA practices evaluate most often: CentralReach, Motivity, AlohaABA, and RethinkBH. It looks at how each handles claim scrubbing, authorization tracking, clinical-billing integration, reporting, and managed billing, and which practice profiles each one fits best. The goal is a clear read you can act on, not a case that one platform wins on everything. Different practices have different priorities, and the right choice depends on your size, billing model, and where you are headed over the next few years.

What to Consider Before Choosing ABA Billing Software

ABA billing software is not generic medical billing with an ABA label on it. Before comparing platforms, weigh the factors that actually decide reimbursement speed, denial rates, and how much administrative load lands on your team.

• Practice size and growth trajectory. The right platform for a 10-person startup is rarely the right one for a clinic with 150 staff across five locations. Match the platform to where you are headed, not just where you are today.
• Billing automation and error prevention. Where claims get checked matters: in real time, after the session, or in a batch before submission. Earlier validation means fewer denials and faster payment.
• Clinical-billing integration. When billing flows directly from completed sessions, you remove duplicate entry and reconciliation. A convert-to-bill bridge between two systems adds both back in.
• Authorization tracking. Most ABA denials trace back to authorizations, not coding. Look for unit tracking, expiration alerts, and documentation that supports the authorization itself.
• Software versus managed services. Some practices want software they run in-house. Others want the revenue cycle handled for them. The most flexible option lets you do either without changing systems.
• Support and implementation. Implementation timelines and training load vary widely. Factor in the learning curve, especially if you hire often or experience turnover in billing roles.
• Data ownership and exit risk. Confirm who owns your clinical and billing data, and how easily you can export claims, authorizations, and notes if you decide to leave.

Detailed Platform Comparison

Each of these four platforms serves ABA practices, and each has invested in automation across documentation, scheduling, and billing. They are built around different priorities. The overview below sets the high-level shape, and the sections that follow go deeper on each one.

RethinkBH: The Integrated, ABA-Specific Platform

RethinkBH runs clinical, scheduling, and billing on a single source of truth, and billing is where that integration pays off. BillAI by Rethink is built directly into the clinical workflow the practice already uses, automating claims from creation to payment posting while catching errors before submission, so practices get paid faster with fewer denials and less manual work. BillAI, is built around one number: day in AR, which is the average time from when a claim is billed to when it is paid. The platform fits mid-market and multi-location practices, roughly 75 to 150 staff and 3 to 10 or more locations, and scales to enterprise organizations running 500 to 5,000 or more employees across multiple states.

What stands out:

• Clinical-billing integration with no extra portals. Automated claim creation pulls directly from appointments and client profiles, and groups or splits charges to match funder rules, location, and authorization requirements, so a completed session becomes a claim without duplicate entry. Billing lives inside the platform the clinical team already uses rather than in a separate system to reconcile.
• Billing automation and error prevention. BillAI’s AI Identify and Track function monitors every claim against expected milestones and uses robotic process automation to correct high-confidence errors automatically, while a two-layer Business Rules Engine validates claims against System Rules maintained across the full client network plus Custom Rules per practice. Built-in validations flag common errors before submission, real-time status tracking surfaces payer rejection codes directly on the claim, and ERA auto-posting reconciles payments and adjustments across multiple claims in seconds. Because the engine retains that payer knowledge, it stays in the system rather than leaving with a departing biller. RethinkBH reports a 99% clean claims rate and practices reporting fewer than 30 days in AR.
• Authorization support, not just alerts. The Medical Necessity Assessment tool supports the authorization itself through assessment documentation and submission tracking, not just a warning that a unit is running low, which matters because authorizations drive a large share of ABA denials.
• Software or managed services on one engine. A practice can run billing in-house, hand it to RethinkBH’s managed RCM service, or move between the two without switching platforms, which is the flexibility most ABA platforms do not offer.
• Billing visibility connected to operations. BillAI surfaces AR aging by claim, funder, and service line, days in AR trended over time, and denial rates by reason code. Because billing shares the platform with clinical and scheduling, that revenue view sits within RethinkBH’s broader operational analytics, rather than in a standalone billing report.

Best fit: RethinkBH is the right choice for practices that have outgrown basic tools and are looking for an enterprise-ready solution. It fits mid-market and multi-location organizations that want clinical-billing integration on one system, plus the option to start with software and add managed billing during growth or staff transitions.

CentralReach: The Enterprise and Multi-Discipline Incumbent

CentralReach is the market leader in ABA practice management, with the broadest feature surface and deepest install base. It is built for enterprise scale, typically practices of 200 or more staff with dedicated administrative resources, and it spans disciplines beyond ABA, which is where it earns a real advantage over ABA-specific platforms.

What stands out:

• Enterprise governance. Audit trails, role-based permissions, and compliance features built for large, multi-site organizations. [8]
• CR ClaimCheckAI. An AI auditing tool that reviews 100% of claims before submission against a library of more than 250 payer-specific rules, scanning for coding mismatches, missing data, and expired authorizations. [7]
• CR ClaimAgentAI. A claims automation and recovery tool that helps providers identify and resolve denials. [7]
• CR BillMax. CentralReach’s managed billing service, which reports an average 92% gross collection rate in the first three months and 97.4% in the first year for its customers. [1]
• Multi-disciplinary billing. For practices that run speech, occupational, physical therapy, or counseling alongside ABA, CentralReach carries billing logic and documentation standards for all of them under one roof. [8]

Best fit: CentralReach is the right choice when your clinical model spans multiple non-ABA therapy types under one roof, or when you are an established CentralReach practice with no pressing pain.

Motivity: The Clinical-First, Growth-Stage Challenger

Motivity centers on clinical usability and is a strong fit for growth-stage practices, roughly 10 to 100 staff, that want clinical staff to own billing accuracy at the point of care. [4]

What stands out:

• Validations in the clinical workflow. Motivity emphasizes catching issues during the session rather than after, so problems are surfaced before a claim is built. [4]
• Per-learner pricing. Motivity’s pricing scales with learners rather than seats, which aligns software cost with revenue for practices with high staff-to-learner ratios. Published rates start at $24 per learner for data collection or practice management and $48 per learner for the all-in-one suite. [10]
• RCM as a service. Motivity offers managed revenue cycle management priced as a percentage of collections, covering payer intake, claim generation, payment posting, denial management, and AR reporting, with biweekly review calls. It works with Availity, Office Ally, Trizetto, and Waystar. [2]
• Modern clinician interface. A clean, current interface built around clinical workflows. [4]

Best fit: Motivity is the right choice for rapid-growth practices that want their clinical team to own billing accuracy at the point of care. Practices tend to outgrow it when governance, analytics depth, and broader platform integration start to matter more.

AlohaABA: The Startup On-Ramp

AlohaABA is an entry point for new and very small practices, generally 0 to 15 staff, that need to get up and running quickly without a heavy implementation. [3]

What stands out:

• Fast, light setup. Clinical staff can learn scheduling in 30 to 45 minutes, and billing staff typically need two initial training sessions. [3]
• Simple per-staff pricing. A straightforward model that is easy to predict for a small team. [3]
• Clearinghouse support with free ERA. AlohaABA integrates with Availity and Office Ally, and there is no extra charge to receive ERAs. [6]
• An integrated suite for the basics. Scheduling, data collection with real-time graphs, authorization management through an AR Manager, and reporting in one platform. [3]

Best fit: AlohaABA is the right choice for solo and startup practices with limited capital and an immediate need to launch. Plan on a two to three-year horizon before a growing practice moves up-market to a platform with more automation and data depth.

Making the Right Choice for Your Practice

The right platform depends on your size, billing model, and how fast you are growing. Here is the short version by practice band.

• Startup, 0 to 15 staff. AlohaABA is the primary pick for capital preservation and speed to launch. If a new practice lacks in-house billing expertise, RethinkBH managed services is the alternative worth weighing.
• Growth-stage, 15 to 50 staff. Motivity fits practices that want per-learner economics and clinical staff owning billing accuracy. RethinkBH is the alternative when authorization complexity, AI-driven efficiency, or the option of managed billing matters. Practices at this stage are usually outgrowing AlohaABA
• Mid-market and multi-location, 50 to 200 staff. This is RethinkBH’s core, with clinical-billing integration, the MNA tool, and the flexibility to move between software and managed billing on one system.
• Enterprise, 200+ staff. CentralReach fits when governance depth, compliance, or multi-discipline care under one roof is the priority. RethinkBH fits when clinical-billing integration and connected revenue cycle workflows are what the organization needs, scaling from 500 to 5,000 or more employees across states while onboarding new locations, and integrating acquisitions without adding complexity.

The Bottom Line

ABA billing software earns its keep by getting claims out clean, catching problems before they become denials, and giving leadership a clear view of the revenue cycle. All four of these platforms can process claims. They differ in how connected the billing is to clinical and scheduling, how the platform scales with a practice, and whether a practice can run billing itself or hand it off without changing systems.

RethinkBH is the strongest fit when a practice wants clinical, scheduling, and billing on one connected system, with billing built around days in AR, authorization depth through the MNA tool, and the flexibility to start with software and add managed services as the practice grows. The right platform is not the one with the most features or the lowest sticker price. It is the one that fits your practice’s size, growth trajectory, internal capabilities, and priorities.

Frequently Asked Questions

How do AlohaABA, CentralReach, Motivity, and RethinkBH differ for ABA billing?

RethinkBH is the only one of the four that runs clinical, scheduling, and billing on a single source of truth and lets a practice choose software-only or managed RCM on the same engine. CentralReach is the broad enterprise platform that also spans non-ABA disciplines, Motivity is a clinical-first option suited to growth-stage practices, and AlohaABA is a simple entry point for new practices.

Why should an ABA practice use ABA-specific billing software instead of a generic medical billing system?

RethinkBH is purpose-built for ABA, so authorization units, overlapping service codes, electronic visit verification, and multi-state payer rules are handled natively instead of worked around. Generic billing systems treat ABA as an edge case, which is where denials and clawbacks tend to start.

Can ABA billing software integrate scheduling, data collection, and EVV in one system?

RethinkBH combines clinical data collection, scheduling, electronic visit verification, and billing in one connected platform, so a completed session becomes a clean claim without duplicate entry. Platforms that bridge separate systems make teams reconcile the same data twice.

Is it better to use ABA billing software in-house or outsource to a managed RCM service?

RethinkBH supports both on the same system, so a practice can run billing in-house, hand it to RethinkBH’s managed RCM service, or move between the two without switching platforms. In-house fits teams with billing expertise, while managed RCM fits practices facing high denial rates, staff turnover, or rapid growth.

What should ABA practices look for in billing software for compliance and security?

RethinkBH is HIPAA compliant and SOC 2 Type II certified with a 99.9% uptime SLA, and it validates every claim against payer rules before submission. For ABA specifically, prioritize authorization tracking, audit trails, and EVV support, since most compliance-driven denials trace back to those.

Which ABA billing software is best for a growing or multi-location ABA practice?

RethinkBH is built for mid-market and multi-location practices, roughly 75 to 150 staff and 3 to 10 or more locations, with centralized oversight, location-specific flexibility, and billing that scales on one connected platform. AlohaABA suits new and very small practices, while CentralReach fits large enterprises with dedicated administrative resources.
