If you've started shopping around for billing help, you've probably noticed something frustrating: almost nobody posts real numbers. You get vague ranges, "it depends" answers, and sales calls that circle the topic instead of landing on it. That's not because billing companies are hiding something shady; pricing genuinely varies based on your claim volume, payer mix, and how much cleanup work your books need. This article breaks down the actual pricing models used across the industry, what drives the cost up or down, and how to figure out which structure makes sense for your practice.

The Three Main Pricing Models

Most ABA billing services fall into one of three buckets. Understanding the mechanics of each will help you compare quotes apples-to-apples instead of getting swayed by whoever quotes the lowest number. Care Collect has helped ABA providers simplify their billing processes and make more informed decisions about managing their revenue cycle. 

Percentage of Collections

This is the most common model in ABA billing, typically running 5% to 9% of collected revenue. If your practice collects $150,000 a month, you'd pay somewhere between $7,500 and $13,500. The appeal here is alignment: the billing company only gets paid when you get paid, so they're motivated to chase denials and follow up on aging claims. The downside is that as your practice grows, your billing costs grow right alongside it, even though the actual labor per claim doesn't necessarily increase at the same rate.

Flat Fee Per Claim

Some ABA Billing Services companies charge a set fee per claim submitted, often $3 to $8 per claim, depending on complexity. This model works well for practices with predictable, high-volume billing since costs stay flat regardless of collection amounts. It's less common in ABA specifically because claim values and session lengths vary so much between clients, making per-claim pricing harder to standardize fairly. 

Flat Monthly Rate

A fixed monthly fee, usually $1,500 to $5,000+, depending on client volume and services included. This suits practices that want predictable overhead and don't want their billing to swing month to month. The catch is that flat-rate providers sometimes cap the services included in that fee, so you'll want to ask exactly what's covered before signing anything.

What Actually Drives the Price Up or Down

A few factors matter more than the pricing model itself.

Claim volume and client count: A practice billing for 15 clients across a handful of payers looks very different from one billing for 80 clients across a dozen insurance panels with different authorization rules.

Denial management needs: If your previous billing setup left a backlog of denied or unpaid claims, expect a one-time cleanup fee on top of ongoing rates. This is common enough that reputable providers will flag it upfront rather than surprise you later.

Authorization and credentialing support: Some providers bundle authorization tracking and payer credentialing into their fee; others charge separately. This is one of the biggest hidden cost differences between quotes that otherwise look similar.

State and payer mix: Billing Medicaid-heavy caseloads often requires more manual follow-up than commercial-payer-heavy ones, which can affect pricing on percentage-based models.

Questions to Ask Before Signing

Before comparing dollar figures, get clarity on what's actually included: Does the fee cover credentialing? Is prior authorization tracking part of the package, or billed separately? What happens with claims denied before the contract started? Who handles patient statements and collections calls? A provider that answers these clearly, without vague hedging, is usually the one worth trusting with your revenue cycle.

Finding the Right Fit for Your Practice

There's no universally "cheapest" option here; the right choice depends on your claim volume, your current denial rate, and how much hands-on support your team needs versus wants to handle in-house. A newer practice with lower volume might do better with a flat monthly rate, while an established practice with fluctuating collections may prefer the percentage model's built-in incentive alignment.
