Why therapists move to therapist practice management software
Most therapists in private practice end up paying for five or six tools: a scheduler, a card reader, a forms service, a reminder service, a spreadsheet for income, and a separate place to build superbills for clients who want out-of-network reimbursement. None of them share data. A new client's details get typed into three places, and every one of those tools is another monthly bill.
Therapist practice management software replaces that stack with one record per client. The booking creates the client, the client signs forms in the portal, the session shows up in the calendar, payment is attached to the session, and the superbill is built from sessions that already happened. Prexella is built around that flow for practices where most clients pay privately.
Built for therapists
Three workflows make up most of a private-pay therapist's week. Here is how each one runs in Prexella.
Workflow 1
New client: from search to first session without a phone call
A prospective client finds your booking page on your own domain, picks an intake session, chooses telehealth or in office, takes an open slot and pays by card. They are guided straight into creating their client portal account, where your intake form, informed consent and telehealth consent are waiting to be signed. You open the session with the paperwork already done.
Workflow 2
Weekly client: prepaid sessions instead of invoices
Move a returning client onto a recurring weekly slot. They buy a block of session credits in the portal, and each completed session draws one down, so there is nothing to chase at the end of the month. Reminder emails go out the day before every session, and telehealth clients get the video link in the same email.
Workflow 3
Out-of-network client: a superbill at the end of the month
Pick the client and the month. Prexella pulls their completed sessions, suggests a CPT code from each session's length, adds your NPI, EIN, license number and the ICD-10 code you enter, and produces a PDF the client can submit to their insurer for reimbursement. You stay out of network; the client still gets money back.
Everything a private-pay therapist uses, and nothing you have to bolt on
- Online bookingPrexella is online booking software for therapists that lets new and returning clients choose a session, telehealth or in office, an open time and pay by card, on your own domain and without a phone call.
- One-click superbillsPrexella is superbill software for therapists that builds an insurance-ready PDF from a client's completed sessions in one click, with CPT, ICD-10, NPI and EIN already filled in.
- Client portalPrexella is client portal software that gives every client one place, on your domain, to book and reschedule, sign forms, pay, message you and complete check-ins between sessions.
- Prepaid session creditsPrexella turns prepaid therapy sessions into a credit balance: clients buy credits or a package up front, every session they book draws from that balance, and the reminders to top up go out automatically.
- Telehealth in the same calendarPrexella handles telehealth scheduling for therapists in the same calendar as in-office sessions: clients choose the visit type when they book, and the right video link reaches them by email and in their portal.
- ESIGN and UETA e-signaturesPrexella gives you e-signature for therapy intake forms built into the practice: clients sign intake, consent, telehealth and financial forms online, and each signature is stored with an ESIGN and UETA audit trail.
- PHQ-9, GAD-7 and C-SSRS screeningsPrexella puts PHQ-9 GAD-7 online screening in the client portal: clients complete validated check-ins between sessions, each one is scored when it is submitted, and the result is saved to the client's record for you to review.
- White-label on your own domainPrexella is white-label practice management software: booking, the client portal and every email run on your own domain under your practice's name, on an instance that belongs to your practice alone.
The online booking page checks every slot on the server before confirming it, so two clients can never take the same hour and nobody can book a date in the past. The client portal is where clients reschedule, sign forms, message you and complete check-ins. Session credits let clients pay ahead. Because Prexella is white-label, all of it carries your name rather than a software vendor's.
Superbills without the spreadsheet
A superbill is often what makes private-pay therapy affordable for a client: they pay you, then claim part of the fee back from their insurer as an out-of-network benefit. The catch is that a superbill missing an NPI, a tax ID or a diagnosis code gets rejected, and formatting one by hand at the end of each month takes time you do not bill for.
The CPT codes therapists bill most, ready on every superbill
Prexella suggests the code from the session length and type, and you can change any line before the PDF is generated. You choose the diagnosis; Prexella formats it.
| Code | What it covers |
|---|---|
| 90791 | Psychiatric diagnostic evaluation (the intake session) |
| 90834 | Psychotherapy, 45 minutes (38–52 minutes of therapy) |
| 90837 | Psychotherapy, 60 minutes (53 minutes or more) |
| 90832 | Psychotherapy, 30 minutes |
| 90847 | Family or couples psychotherapy with the client present |
Every Prexella superbill carries your practice name, credentials, NPI, EIN, license number and taxonomy code, the client's details, the ICD-10 diagnosis you enter, each date of service with its CPT code and place of service (office, or telehealth from the client's home), and fees paid. The full field list is on the superbill feature page.
How Prexella compares with SimplePractice
SimplePractice is the system most therapists we talk to are moving from, so here is the short version. The full side-by-side, with pricing math for a three-clinician practice, is in Prexella vs SimplePractice, and a wider list is in SimplePractice alternatives.
| Prexella | SimplePractice | |
|---|---|---|
| Pricing model | One flat fee for the practice | $49–$99/mo per account; extra clinicians from $74/mo each (Plus) |
| Your own domain and branding | Yes, on every client-facing page and email | Not listed on their pricing page |
| Superbills | One click from completed sessions | Not listed on their pricing page |
| Marketing tools | Built-in marketing suite and newsletter | Appointment request widget (Plus); no marketing suite listed |
| Prepaid session packages | Session credits in the client portal | Not listed on their pricing page |
SimplePractice is a strong choice if you bill insurance heavily or want its AI note tools; it lists more clinical documentation features than Prexella does. Prexella is the better fit when your clients mostly pay privately, you want the practice to carry its own brand, and you want marketing in the same system as scheduling.
Pricing
Prexella is priced as one flat fee for the practice rather than per clinician, so adding an associate or a part-time therapist does not multiply your software bill. Pricing depends on how your practice is set up; request a demo and you will get a quote for your practice on the call.
What switching looks like
Most practices move in one billing cycle: export what your current system lets you export, have your services and forms set up in Prexella, point new bookings at your new booking page, and let existing appointments finish in the old system. The steps are on how to switch to Prexella. If you work with couples and families, see the page for marriage and family therapists; if you are a licensed counselor, see counselors.
Frequently asked questions
Is Prexella only for cash-pay therapists?
It is designed for private-pay and out-of-network practices. Superbills cover clients who claim reimbursement themselves, and the insurance billing workspace lets an in-house or outsourced biller prepare claims if you also take insurance.
Can I use my own website and domain?
Yes. Booking, the client portal and every email run on your domain with your practice name. Clients do not see Prexella's name.
Does Prexella include video for telehealth?
Prexella schedules telehealth and in-office sessions in one calendar and sends clients the join link by email. The video itself runs in the HIPAA-ready video tool you already use, such as Doxy.me or Zoom for Healthcare.
Can clients prepay for a block of sessions?
Yes. Clients buy session credits in the portal and each completed session uses one. You can see every client's balance from the dashboard.
How long does it take to get started?
Prexella is set up for you. On a setup call the team configures your services, fees, forms, booking rules and branding, so you are not building it alone. Request a demo to see it with your own session types first.
