How much does it cost to build an app like MyCase?
Estimated US development cost, the features and surfaces involved, the team and timeline it takes, the infrastructure it needs at scale, and what it costs to run once it is live.
A practice management platform for small law firms covering case organisation, documents, calendaring, time tracking, invoicing, payments and a client communication portal, with an emphasis on ease of use over configurability.

The calculator returns
It is not one app — it is 3
The most common reason a budget for something like this comes in low is counting one application when the product needs several, plus the shared platform underneath that nobody sees.
Applications people use — 3
Firm workspace
Web · iOS · Android
Lawyers and staff
Cases, documents, calendar, deadlines, time tracking, tasks and communications.
Client portal
Web · iOS · Android
Firm clients
Secure messages, shared documents, case updates, invoices and online payment.
Billing & trust
Web
Firm administrators
Invoicing, retainers, trust ledgers, reconciliation and financial reporting.
Shared platform underneath — 9
Backend & API
The shared data model, business rules and the API every side reads and writes through. Built once, and the single largest line in almost every estimate.
Identity & permissions
Sign-in, sessions, second factors and a role model enforced on the server. Multi-sided products need one identity system that understands several kinds of user.
Payments & money movement
Charging, refunding, paying out, reconciling and surviving audit. Never just an SDK call — the ledger and the failure paths are the work.
Notification system
Templating, preferences, delivery across push, email and SMS, retries, and the suppression rules that stop a product becoming spam.
Real-time transport
Persistent connections, presence, fan-out and reconnection. A separate scaling problem from the request/response API, with its own capacity model.
AI services & governance
Model access, retrieval over your own content, evaluation and guardrails. The governance half is the part that gets cut and then rebuilt after an incident.
Admin & operations console
Where your own staff fix what customers cannot: account issues, refunds, overrides, escalations. Consistently underbudgeted, and consistently the reason support costs balloon.
Analytics & reporting
Event instrumentation, a warehouse and the dashboards the business actually runs on. Retrofitting instrumentation costs several times what building it in does.
Infrastructure & delivery
Environments, pipelines, secrets, monitoring, alerting and on-call. The work that makes everything above deployable more than once a month.
What has to be built
Split by the phase each capability realistically lands in. The MVP column is priced as its own configuration above, so the split is a real costing decision rather than a diagram.

Technology a build like this would use
Derived from the platforms and capabilities above.
These are typical choices for building a product of this shape today. They are derived from the platforms and capabilities described above — not a claim about what MyCase actually runs on. We do not publish other companies’ internal technology, and you should be sceptical of anyone who does.
Mobile
- React Native or Flutter (one codebase)
- Swift / SwiftUI (native iOS)
- Kotlin / Jetpack Compose (native Android)
Two native codebases buy platform fidelity and cost roughly 66–70% more on the client than one shared codebase. Cross-platform is the default unless a specific capability forces native.
Web
- TypeScript
- React with Next.js
- Tailwind CSS or a component library
Server rendering matters here if the pages need to be indexed; if the web surface is an authenticated console only, it does not.
Backend
- Node.js or Go for the real-time edge
- Python or Java for domain services
- gRPC or REST between services
A real-time product usually ends up with two server profiles: a connection-handling tier tuned for many idle sockets, and a conventional application tier behind it.
Data
- PostgreSQL (primary transactional store)
- Redis (cache, sessions, queues)
- Snowflake or BigQuery (analytics warehouse)
- pgvector or a managed vector database
One relational database plus a cache covers more products than teams expect. Add a specialist store when a real query pattern demands it, not in anticipation.
Cloud & delivery
- AWS, Google Cloud or Azure
- Containers on a managed orchestrator
- Terraform or equivalent for infrastructure as code
- GitHub Actions or similar for CI/CD
The architecture tier this product needs is driven by traffic, not preference — see the scale section below.
Payments
- Stripe, Adyen or Braintree
- Apple Pay and Google Pay via the platform SDKs
- A double-entry ledger you own, not the processor's balance
Using a processor keeps card data out of your systems and shrinks PCI scope dramatically. It does not remove the need for your own reconciliation.
Messaging & notifications
- APNs and FCM for push, usually via a delivery service
- Twilio for SMS and voice
- SES, SendGrid or Resend for email
Deliverability is an operational discipline: warm-up, domain authentication, bounce handling and suppression lists. It is not solved by picking a vendor.
AI
- A hosted model provider (Anthropic, OpenAI) or Bedrock
- Retrieval over your own content with a vector index
- Evaluation harness and output guardrails
Token cost scales with usage, so unit economics need modelling before launch. The evaluation and guardrail layer is what separates a demo from a product.
Observability
- Sentry for errors
- Datadog, Grafana or an equivalent for metrics and traces
- Structured logging with retention matched to your compliance regime
Instrumentation is cheapest when added during the build. Retrofitting it after the first production incident costs several times more.
How an app like MyCase works
The functional territory mirrors larger practice management platforms — matters, time, billing, trust accounting — but the customer is a firm of a handful of lawyers with no IT staff. That reframes the engineering priorities toward onboarding, sensible defaults and getting trust accounting right without the user needing to understand it. Client communication is emphasised more heavily, because small firms compete on responsiveness and the portal reduces the phone calls that consume their day.
In costing terms that shape matters more than the feature count. A records & documents in legal & professional services inherits obligations before anyone designs a screen — this sector rates 4 out of 5 for regulatory and procurement difficulty on this site, and that rating is what drives the security posture, the audit work and the integration surface any estimate has to carry.
MVP versus the full product
A first version of this is a materially smaller build than the mature product, and the calculator will show you by how much. It gets there by shipping fewer features, on fewer surfaces, at a launch-sized audience rather than the traffic the mature product carries.
What it does not cut is compliance. A regulated product is regulated from its first user, so the primary regime stays in the MVP even though almost everything else is deferred. Teams that defer it discover that retrofitting audit logging, access control and data retention costs several times what building them in would have.
Monetisation
How products of this shape make money
- Per-user monthly subscription
- Payment processing fees
- Add-on modules for accounting and intake
- Onboarding services
Generic to the category, not a description of MyCase’s commercial arrangements.
What these numbers are, and are not
This page carries no figures deliberately. What it sets out is the shape of the build — the sides, the tiers, the stack, the compliance — because that is what an estimate is derived from and what you can check. The calculator turns your own version of that shape into a planning estimate with a stated confidence band; use it to decide the order of magnitude, then spend two to four weeks on a technical specification and get a real quote against that document.
Nothing here is a statement about MyCase as a company. We do not know and do not publish what any business spent building its product, what it earns, how many people it employs, or what technology it runs on. What we describe is the product shape any user can observe — the surfaces it presents, the roles it serves, the capabilities it evidently has — and what building that shape would cost in the United States today.
Building an app like MyCase, answered
How much does it cost to build an app like MyCase?
There is no one figure, because "an app like MyCase" covers three very different builds: a first version with only the essential features, a complete and credible competitor, and a rebuild of everything the mature product does at the traffic it carries. Those are several-fold apart. What this page gives you is the shape of each — the sides, the feature tiers, the stack and the compliance — and the calculator turns whichever one you actually mean into a cost range, hours and a timeline.
Why is an app like MyCase more expensive than a typical app?
Because it is not one app. It is 3 separate applications — firm workspace, client portal, billing & trust — sharing one backend, each with its own design, release cycle and test matrix. Most quotes that come in low have counted one of them. Trust accounting without an accountant: The rules are identical to those larger firms face, but the user has no bookkeeper. The system must make compliant behaviour the default and make violations difficult, because the customer will not catch the error.
Could I build a cheaper version first?
Yes, and you should. A first version ships the essential feature tier rather than all three, on fewer surfaces, at a launch-sized audience — materially less than the full product, and the calculator will show you by how much. What it does not cut is compliance: legal & professional services obligations apply from the first user, so those stay in whatever else is deferred.
How long would it take to build?
It depends on the same three things the cost does — which tier of the product you mean, how many surfaces you ship, and how settled the scope is. The calculator returns a timeline alongside the cost, derived the same way: hours divided across a realistic team shape, never a target date worked backwards from.
What does it cost to run once it is live?
Cloud infrastructure, third-party services and annual maintenance, and the calculator reports all three separately from the build. They are kept out of the build figure deliberately: they are operating expenditure rather than capital, and adding the two together produces a number that means nothing. Maintenance in particular is not optional — an app that receives none stops working within about a year as OS releases and SDK deprecations accumulate.
Are these real figures for MyCase?
This page carries no figures at all, and nobody outside the company has real ones. What it describes is the product SHAPE, observed from what any user can see — the sides, the feature tiers, the stack, the compliance. Nothing here describes what MyCase actually spent, earns, employs or runs on. The calculator prices building something of that shape today, for the United States market, at our own blended delivery rate.
Can we use AI for drafting and document review?
Yes, and clients increasingly expect it, but the professional liability changes the engineering. Every AI output needs source attribution, a human review step and an audit record of who accepted what. Retrieval over the firm’s own documents rather than open-ended generation is the pattern that works. Budget $50,000–$120,000 for a properly grounded, evaluated implementation — most of that in retrieval quality and evaluation rather than the model call.
How accurate is this estimate?
It is a planning estimate, not a quote. The band shown is roughly plus or minus 15–20% for a well-defined scope, and wider while requirements are still moving. It is built from engineering hours per discipline, converted at our blended delivery rate, so the hours are directly comparable to a real proposal line by line — but a firm price needs a technical specification, which is the step after budgeting.
