TheraNest vs SimplePractice: Which Is Better for Your Practice?

Short answer: TheraNest is usually cheaper, especially for practices with variable caseloads, because it prices on active clients rather than a flat per-seat fee. SimplePractice is the more polished product with a better mobile app and a deeper ecosystem. The deciding factor for most practices is not features, it is whether your caseload fluctuates enough for TheraNest's pricing model to pay off.

One thing we would flag before you switch to TheraNest, and we will come back to it below: the migration experiences practices have described to us have not been good.

We make a competing product, so the closing section is an advertisement. Everything before it comes from what practices told us and what the vendors publish. Oasys sits at the infrastructure layer of working practices, and from our ongoing conversations with therapists and group practice owners we hear both of these platforms discussed constantly.

At a glance

On pricing. SimplePractice publishes Starter at $49, Essential at $79 and Plus at $99 a month. Group practices need Plus, with additional clinicians tiered at $74 each for two to five, $72 for six to fifteen, and $69 for sixteen or more. TheraNest starts around $29 per therapist per month, tiered by active clients rather than seats. Verified 30 July 2026; confirm before you sign anything.

The pricing difference is the real difference

TheraNest charges by active clients. SimplePractice charges by clinician. That sounds like a detail and it is actually the whole decision.

If your caseload is steady and full, per-clinician pricing is predictable and often cheaper. If your caseload swings, if you run seasonal fluctuation, or if you carry part-time clinicians with light rosters, active-client pricing can be meaningfully less.

The corollary is that TheraNest's bill moves. Practices that like knowing next month's number in advance sometimes find that uncomfortable even when the average is lower.

Where SimplePractice wins

Polish and mobile. SimplePractice is the nicer product to use daily and its mobile app has no real rival in the category.

Ecosystem. A large user base means the template you need or the answer to your workflow question probably already exists.

Client experience. The portal is straightforward enough that intake friction drops, which practices notice in completion rates.

Where TheraNest wins

Cost at variable volume, per the pricing model above.

Group and family session handling is reasonable, and practices doing meaningful group work sometimes prefer it.

Straightforward billing workflows for practices that do not need heavy customization.

Telehealth and insurance billing

Telehealth is close to a wash between the two. TheraNest and SimplePractice both include built-in, HIPAA-compliant video as a standard part of the platform, not a paid add-on, so telehealth on its own rarely decides this comparison either way.

Insurance billing is where the gap opens. SimplePractice's larger ecosystem and longer track record with payer connections give it more depth for a practice running real claim volume across multiple payers. TheraNest's billing works, and practices that do not need heavy customization describe it as straightforward, but it stays the simpler of the two once claim volume gets real.

The migration warning

This is the part we would want to know before switching, and it is specific rather than general.

A practice that moved from another platform to TheraNest described the experience to us in detail:

"That was a nightmare. It was very complex. And we couldn't get the support that we needed despite paying extra for the white glove onboarding service. Things were migrated over and done incorrectly. People gave us contradictory answers and incomplete answers. And so we were really just chasing our tails for a couple of months."

That is one practice, and one practice is not a pattern. We are reporting it because the detail is unusually specific: they paid for premium onboarding and still ended up with incorrect data and months of cleanup. If you are considering TheraNest, ask them directly about migration references and get the answer in writing.

More broadly, this is the reason practices stay on platforms they have outgrown. Group practices carry eight to eleven years of records, and the sentence we hear in a dozen forms is we cannot do it twice.

Where both strain

Neither platform models supervision by credential status, so a provisionally licensed clinician who is independently credentialed with payers gets the same forced co-sign as a first-year intern. Neither models payroll, so compensation gets rebuilt in a spreadsheet. One group practice put about 20 hours a week of a billing manager's time into exactly that conversion.

Those gaps do not matter at five clinicians. They matter a lot at twenty.

Which should you choose?

Choose TheraNest if your caseload fluctuates, cost predictability matters less than average cost, and you are willing to do thorough diligence on migration.

Choose SimplePractice if you want the better daily experience and mobile app, and your caseload is steady enough that per-clinician pricing works out.

Consider neither if supervision, permissions, or payroll are what actually hurt.

FAQ

TheraNest vs SimplePractice: which is better for practice management, telehealth, and insurance billing? Practice management comes down to the pricing model above: TheraNest for a fluctuating caseload, SimplePractice for a steady one. Telehealth is close to equivalent, since both include it as a standard feature. Insurance billing favors SimplePractice once claim volume is real, because its ecosystem and payer connections run deeper than TheraNest's.

Is SimplePractice or TheraNest better for a group practice? Neither is built specifically for group-practice mechanics. Both work reasonably at a handful of clinicians and both show the same strain past that: no supervision model by credential status, no native payroll. Choosing between them should come down to pricing model and daily usability, not which one is built for scale, because neither is.

How does TheraNest vs SimplePractice compare to TherapyNotes? TherapyNotes is worth including in the same evaluation, particularly for insurance-heavy practices, since its billing and claims workflows are generally more built-out than TheraNest's. It does not close the supervision or payroll gap either. A practice weighing all three should compare pricing model, billing depth, and daily usability together rather than narrowing to two of the three too early.

What if a practice has outgrown what either platform offers? That is usually a supervision, permissions, or payroll problem, not a TheraNest-versus-SimplePractice problem. Oasys models supervision by role and credential status, carries role-based permissions, and produces the payroll ledger directly rather than requiring a spreadsheet, which is where both TheraNest and SimplePractice hand the work back to the practice.

Our position, labeled

We make Oasys, an EHR for mental health group practices, at $80 per clinician per month on an annual contract with no add-ons. Other platforms are built differently. Oasys configures supervision per role, carries role-based permissions, and produces the payroll ledger rather than requiring you to build it.
