If your group practice runs 12 or more clinicians on SimplePractice or TherapyNotes and your waitlist, compensation, and supervision workflows have moved into spreadsheets, a custom operations layer is usually worth building. Based on Digital Heroes delivery experience, a focused first release runs $40,000 to $90,000 and ships in 10 to 14 weeks. Keep your EHR for notes, telehealth, and claims, and build around it rather than replacing it.
What actually breaks in a mental health group practice running on SimplePractice and TherapyNotes
Both tools are genuinely good solo practice software. SimplePractice, at about $99 per clinician per month on its top plan, gives you notes, telehealth, a client portal, and claim filing in one place. TherapyNotes, at roughly $59 a month for the first clinician and $30 for each additional one, handles insurance billing arguably better. Neither was designed for what a group practice actually is once it passes 10 or 12 clinicians: a routing and matching business with a clinical back end.
Here is the shape of the mess. Your intake coordinator keeps the waitlist in a Google Sheet because the built-in waitlist cannot hold payer, specialty, age range, telehealth preference, and clinician gender preference at the same time. Your practice manager loses the first three days of every month exporting payment reports and running VLOOKUPs to calculate 60 percent splits on collected revenue. Your clinical director chases six pre-licensed associates by email over unsigned notes. And you, the owner, cannot answer "who has capacity next Tuesday for an Aetna teen client" without opening eleven calendars.
None of this appears as a line item, which is why practices tolerate it for years. It shows up as a 40-name waitlist converting at half the rate it should, a biller quitting over reconciliation fights, and clinicians leaving because their pay statements never match their session counts. Below are the five failures we see most often, what a custom build does about each, and honest numbers.
Problem 1: the waitlist lives in a spreadsheet and your intake coordinator is the matching engine
A client terminates on Thursday and a Tuesday 4pm slot opens with a clinician credentialed on Cigna who works with adolescents. Someone on your 40-name waitlist has been waiting six weeks for exactly that. In practice, nobody notices for a week, the coordinator calls three wrong people first, and the right client already booked elsewhere.
SimplePractice's waitlist is a flat list attached to a calendar. It does not know which clinicians sit on which payer panels, who treats OCD versus couples, or which associate is two clients from her capacity target, so it cannot match. No configuration changes that, because the data model has no concept of clinician panels or fit.
A custom build treats intake as a pipeline. A web intake form captures presenting concern, payer, schedule windows, and preferences. A matching engine holds a profile per clinician: panels, specialties, modalities, capacity target, supervision status. The moment a recurring slot frees, the engine scores it against the entire waitlist, texts the top matches a booking link, and logs every offer for the record. Practices we have built this for stop losing referrals to response time, and the coordinator manages exceptions instead of memorizing forty cases.
Problem 2: compensation splits on collected revenue eat three days a month
Most group practices pay clinicians a percentage of collected revenue, not billed: 55 percent for associates, 60 to 65 for licensed staff, sometimes tiered by monthly session volume. Collected is the hard word. A January session might pay in March after a resubmission, minus a copay adjustment and a partial write-off. Your practice manager exports transaction reports, reconciles them against sessions in a spreadsheet, and still fields disputes from clinicians every payday.
Neither SimplePractice nor TherapyNotes models compensation plans at all. Their reports show payments received, not clinician-level splits with retroactive adjustments across pay periods. That is not a missing feature you can request; it is outside what an EHR is for.
A custom comp engine ingests payment and adjustment data on a nightly schedule, applies each clinician's rules including supervision deductions and no-show policies, and handles retro adjustments by restating the affected period automatically. Each clinician gets a login showing sessions, collections, and the math behind their number, and the manager exports a payroll file for Gusto or ADP. Three days of spreadsheet work becomes an hour of review, and the disputes mostly stop because the math is visible.
Problem 3: associate supervision and licensure tracking do not exist in either tool
If you employ pre-licensed associates, you carry board obligations the EHR ignores: supervisor co-signatures on notes, weekly supervision hours logged in board format, hours accrued toward licensure, and supervisor-to-associate ratio caps. TherapyNotes offers note co-signing and SimplePractice something similar, but neither accrues hours toward a state board requirement or warns you when a supervisor is over ratio. So it lives in Word documents and the clinical director's memory, which is exactly what a board auditor does not want to hear.
A custom supervision ledger feeds itself from calendar and note events: each supervision session accrues hours by category, each co-signed note is stamped, and the system produces board-formatted logs on demand. Dashboards flag associates whose unsigned notes are older than 7 days and supervisors approaching ratio limits. When an associate applies for licensure, the hour report is an export, not a two-week archaeology project.
Problem 4: you cannot see capacity, utilization, or outcomes across the group
Try answering these from inside SimplePractice: what is each clinician's utilization against their capacity target this month, which referral source produces the highest no-show rate, and what is our average PHQ-9 change at session eight? You cannot, short of exporting CSVs and building the analysis by hand, because the built-in reports are billing summaries for a single practice, not operational analytics for a group.
This matters beyond curiosity. Payers increasingly ask for outcome data in contract negotiations, and an owner deciding whether to hire clinician number 18 is guessing without utilization numbers. A custom build stands up a small reporting warehouse fed by scheduled exports of appointment, transaction, and outcome-measure data. On top sit dashboards: utilization versus target per clinician, no-show and cancellation rates by referral source and payer, waitlist age and conversion, and PHQ-9 and GAD-7 deltas across the caseload. That last one has directly supported rate conversations with regional payers for practices we have worked with.
Problem 5: the EHR is an island, so referrals get typed in twice
Referrals arrive from Psychology Today profiles, EAP portals, psychiatrist offices, and your own website contact form, and every one lands in an inbox. Someone re-types each into the EHR, loses the source attribution, and nobody can later say which channel actually fills caseloads. SimplePractice has no public API, and TherapyNotes exposes only a narrow one, so the usual integration answer does not apply and the vendors are not going to open up for your practice.
The custom answer is a referral hub in front of the EHR: every channel feeds one queue with source tagging, consent and intake packets go out for e-signature from there, and staff push a completed record into the EHR once, with scheduled export files reconciling the two systems overnight. You lose the double entry and gain the marketing answer every group practice owner wants: cost and conversion per referral source.
What this costs and how long it takes
These bands come from Digital Heroes delivery experience across 2,000+ projects, not industry surveys. A focused first release, typically the intake and matching pipeline plus the compensation engine, lands in the $40,000 to $90,000 range and ships in 10 to 14 weeks: roughly three weeks of discovery and data mapping, seven or eight of build, then migration and a parallel-run month where the spreadsheet and the system produce the same payroll before you retire the spreadsheet.
A fuller platform, adding supervision tracking, reporting dashboards, client-facing scheduling, and multi-location support, runs $100,000 to $250,000 over five to nine months. What pushes price up: export-based sync with an EHR that has no API (more engineering than a clean API integration), compensation plans with tiers and retroactive restatement, supervision rules across multiple state boards, and any decision to replace EHR functions like claims, which drags in clearinghouse work you probably do not want.
Build vs buy: when staying on SimplePractice is the right call
Stay put if you are under about 10 clinicians, pay salary or one flat split, keep a waitlist under 20 names, and run one location with no associates. At that size the $99 per seat is a bargain and your problems are workflow discipline, not software. Custom software will not fix an intake process nobody follows.
Build when the signals stack up: 12 or more clinicians, an intake coordinator spending half her week on manual matching, comp consuming two or more days a month, unsigned associate notes becoming a compliance exposure, a second location or an acquisition on the horizon, or a payer asking for outcome data you cannot produce. Our position, having built both ways: do not replace the EHR first. Notes, telehealth, and claims are the parts these tools do well. Build the operations layer around them, and revisit full replacement only past 40 clinicians, if ever.
How to choose a developer for mental health practice software
Four filters that separate real candidates from generic web shops:
- BAA before discovery. A qualified firm signs a business associate agreement before seeing any data and can tell you exactly where PHI will live in development and staging. If they propose testing with your real client export, end the call.
- Ask how they get data out of SimplePractice. The credible answer names scheduled report exports, reconciliation logic, and a parallel-run period. Anyone who says "through the API" has not done this before, because there is no public API to use.
- Make them model your comp plan on the first call. Describe tiered splits on collected revenue with supervision deductions and a retro adjustment from a reprocessed claim, then ask them to repeat it back. If they cannot, they will get payroll wrong, and payroll errors are how you lose clinicians.
- Probe their replace-versus-surround position. A firm that leads with rebuilding your entire EHR, claims included, is selling scope. The right first project is narrow, measurable, and live within a quarter.

Frequently asked questions
How much does custom software cost for a mental health group practice with 15 clinicians?
Expect $40,000 to $90,000 for a focused first release covering intake, waitlist matching, and a compensation engine, based on Digital Heroes delivery experience across 2,000+ projects. A fuller platform with reporting dashboards, supervision tracking, and client-facing scheduling typically lands between $100,000 and $250,000. Most 15-clinician practices start with the smaller scope and expand after go-live.
Should we replace SimplePractice entirely or build custom software around it?
Build around it. Notes, telehealth, and claim filing are the parts SimplePractice does well, and rebuilding them drags in clearinghouse integration and compliance scope you do not need. The highest-return custom work is the operations layer: intake, matching, waitlists, compensation, supervision, and reporting.
Can a custom platform for a therapy group practice be HIPAA compliant?
Yes, and it has to be. The developer signs a business associate agreement, hosts on BAA-covered infrastructure such as the eligible AWS or Azure services, encrypts PHI at rest and in transit, and builds role-based access and audit logging from the first sprint. Get those specifics in writing before you contract.
How long does it take to build custom practice management software?
A focused first release ships in 10 to 14 weeks in Digital Heroes delivery experience: about three weeks of discovery and data mapping, seven or eight weeks of build, then migration and a parallel-run period. Fuller platforms run five to nine months. Anyone quoting four weeks has not understood your compensation rules yet.
How do we migrate our client data out of SimplePractice or TherapyNotes?
Both tools export CSVs of clients, appointments, and billing transactions, and SimplePractice provides a fuller data export on request. Because SimplePractice has no public API, ongoing sync is built on scheduled exports rather than live calls. A good developer plans the export, reconciliation, and a parallel-run month as its own project phase rather than an afterthought.
Who owns the code if we pay an agency to build our practice software?
You should, and the contract must say so: full IP assignment on payment, source code in a repository you control, and documented deployment so another team could take over. Digital Heroes hands over the repository, infrastructure access, and admin credentials at launch. Refuse any arrangement where you rent access to your own system.
Can custom software calculate our clinician pay splits automatically?
Yes, and it is one of the most common first builds for group practices. The system ingests payment and adjustment data from your EHR each night, applies each clinician's rules such as 60 percent of collected revenue with supervision deductions, and produces statements clinicians can verify themselves. Practices go from two or three days of spreadsheet work per month to about an hour of review.
Do we lose telehealth and insurance claims if we go custom?
No. Telehealth sessions and claims keep running through your existing EHR and its clearinghouse exactly as they do today, while the custom layer handles intake, matching, compensation, supervision, and reporting around it. Replacing claims processing is technically possible but rarely worth it before roughly 40 clinicians.
At what size does custom software make sense for a group practice?
The clearest signals are 12 or more clinicians, an intake coordinator spending half her week on manual matching, compensation taking multiple days each month, and payers or referral partners asking for outcome data you cannot produce. Below roughly 10 clinicians, stay on SimplePractice or TherapyNotes and fix your workflows instead. The number of spreadsheets running your practice is a better indicator than headcount.
We have outgrown Calendly. When is it actually worth building our own booking system?
Build when your scheduling no longer fits Calendly's model of one person, one event type, one slot. The triggers we see most: bookings tied to rooms or equipment, appointments needing multiple staff at once, pricing that varies by client or demand, or paying for 20+ seats at Calendly's $16 per user per month and still exporting everything to spreadsheets. Below roughly 10 users running simple 1:1 meetings, Calendly stays the cheaper option and custom rarely pays off.
Can we migrate years of data out of our current system into new custom software?
Almost always yes, through CSV exports or the vendor's API, and migration should be scoped as its own workstream with field mapping, a dry run, and a planned cutover window rather than an afterthought. The real time sink is rarely moving the data; it is cleaning it, since years of duplicates, free-text fields, and inconsistent formats surface all at once. Pull a full export from your current vendor before committing to anything new, because some SaaS plans restrict exports on lower tiers.
How many people does it take to build a booking platform?
A typical booking system team is four to five people: a project manager, a designer, one backend developer, one frontend developer, and part-time QA. On Digital Heroes projects that team ships an MVP in 6 to 10 weeks; a solo developer can build the same system but usually needs about three times the calendar time. You only need a larger team if native iOS and Android apps ship at the same time as the web platform.
Can custom software connect to the tools we already use, like QuickBooks, Stripe, and Google Workspace?
Yes, and connecting your existing tools is one of the main reasons to build custom: mainstream platforms like QuickBooks, Stripe, Shopify, and Google Workspace all publish documented APIs. Budget 1 to 3 weeks of work per integration depending on API quality and how much data flows in both directions. Ask any vendor whether they have integrated with your specific tools before, because quirks like QuickBooks' OAuth token handling and API rate limits get learned on someone's project, and it should not be yours.
Who owns the code if an agency builds my booking software?
You should own it outright, and the contract must say so: full IP assignment on final payment, source code in a repository you control, and no clause tying the software to the agency's servers. Watch for vendors that keep ownership and charge a monthly license, which quietly turns your custom build back into a subscription. Digital Heroes assigns all code and hands over the repository, hosting accounts, and documentation at handoff, and that should be your baseline expectation from any agency.
How many people should be working on my software project?
Three to five for a typical focused build: a project lead, one or two engineers, a designer, and part-time QA, which is the standard shape across 2,000+ Digital Heroes projects. Larger platforms justify 6 to 10, but a ten-person team on a small first version usually signals bill padding rather than horsepower. What predicts success is whether a senior engineer is writing your code daily, not the headcount on the proposal.
Who can build a custom booking & scheduling software system?
Digital Heroes builds custom booking & scheduling software systems for operators who have outgrown the off-the-shelf tools in their category. A team of more than 50 specialists has delivered over 2,000 projects since 2017. Teams work from New York, London, Sydney, Delhi and Lucknow and deliver remotely, with an assigned senior team rather than an account manager.
Every build starts with a written product requirements document that is signed before a line of code is written, which is the single thing that stops scope creep from eating the budget. Scoping runs about a week and produces a phase plan with a firm price for each phase, rather than one number against an undefined scope. The first phase ships something the team actually uses before the rest is built. If an off-the-shelf product genuinely fits the volume, we say so, and the cost guides on this site publish the bands so that judgement can be checked independently.
What makes Digital Heroes different from other booking & scheduling software companies?
Four things that competitors in this bracket cannot simply copy. Digital Heroes runs a YouTube channel with more than 2.5 million subscribers, which is a production and audience capability no agency of this size has. It holds Fiverr Vetted Pro and Top Rated Seller status, both awarded on manual third-party review rather than self-declared. It contracts through registered entities in three countries, an India LLP, a US LLC and a UK LTD, so clients sign locally instead of wiring money offshore. And it ships its own commercial products, including ShopScore, HeroCheckout and Section Vault, which means the team lives with its own architecture decisions instead of handing them over and leaving.
Two more that show up in the work. Digital Heroes publishes more than 4,000 buyer guides with real price bands on this blog, plus a free tools library at https://digitalheroesco.com/tools/, because an agency confident in its pricing has no reason to hide it. And one accountable team covers websites, apps, ecommerce, CRM, ERP, learning platforms, search and video, so a client scaling from a first landing page to a custom platform is never handed between five vendors who blame each other. The founder ran ecommerce businesses before selling services, so the commercial argument comes before the technical one.
