What is patient portal development?

Patient portal development is the design and build of a secure web and mobile experience where patients manage their care online: booking appointments, messaging providers, viewing records and lab results, requesting refills, and paying bills, all connected to your EHR or practice system.

How much does patient portal development cost?

Cost depends on scope. A starter patient portal with sign-in, scheduling, messaging and a records view starts from around $25,000 and typically launches in 6–10 weeks. Standard portals with EHR integration, billing and payments, prescriptions and a mobile app typically run $50,000–$120,000, and advanced multi-facility portals with proxy access, wearable data and AI features $120,000–$250,000+. Share your workflows and we will scope and price your build.

How long does it take to build a patient portal?

Most MVPs go live in 6–10 weeks, depending on your workflows and integration needs. We deliver in sprints with clinical validation built in, then add modules over time.

Can the portal integrate with our EHR?

Yes. We build HL7 and FHIR-based integrations with existing EHRs, lab systems, imaging software, and third-party tools, so patients see current data without duplicate entry.

How do you keep patient data secure and compliant?

HIPAA, GDPR, ABHA, and 21 CFR Part 11-aligned data handling is built into every portal we develop, alongside OWASP security standards, encrypted storage, audit logs, and role-based access control.

Do you build web and mobile patient apps?

Yes. We build responsive web portals and cross-platform mobile apps from a shared codebase, for example Cresco Healthcare's web platform and React Native app for booking tests and viewing digital reports.

What should I look for in a patient portal development company?

Look for a team with delivered patient-facing platforms, real EHR integration experience, compliance built in from day one, and clear ownership of the code, IP, and data. Ask to see comparable live builds; we've delivered patient-facing telehealth, diagnostic, and research portals.

Can you improve or replace our existing patient portal?

Yes. We can extend an existing portal with new modules, connect it to new systems, or rebuild it, and we migrate data securely with minimal disruption to your operations.

Patient Portal Development Services

Patient Portals That Reduce Admin Load and Keep Patients Engaged

As a patient portal development company, we build secure, HIPAA-compliant portals and patient apps that connect to your EHR — so patients can book visits, message their care team, view records and results, and pay bills without calling the clinic.

Types of Patient Portals We Build

The right portal depends on who uses it and what they need to do. These are the four we build most often.

Clinic and practice portals

Booking, messaging, intake forms, visit summaries and payments for practices and specialty clinics, connected to the EHR you already use.

Hospital and multi-facility portals

One patient login across departments and sites, with records, results, billing and appointments pulled from several systems.

Specialty and chronic-care portals

Condition-specific experiences, such as care plans, device and wearable data, symptom tracking and follow-ups, for care teams that manage patients between visits.

Illustration of a participant app with a consent document

Research and participant portals

Secure participant-facing portals for consent, assessments and data capture, like the one we built for the world’s largest ALS patient dataset.

Most portals also include proxy and caregiver access, so a parent or family member can manage care for someone else with permissions the patient controls, and multilingual, accessibility-aligned design on web, iOS and Android.

Custom, White-Label or Buy: Choosing the Right Route

There is no single right answer. The best route depends on how different your workflows are, how many systems the portal must connect to, and how long you plan to use it.

Illustration of a ready-made software package with a price tag

Buy an off-the-shelf portal

Fastest to start and usually priced per provider or patient, but the experience and roadmap follow the vendor, and integrations beyond the standard ones can be limited.

White-label and customise

A middle path: start from a ready base and adapt branding and some workflows. Works when your needs are close to the standard product.

Illustration of software building blocks and gears

Build a custom portal

Your workflows, your design, your data and full ownership. Worth it when the portal is part of your product or must connect to several systems.

Many teams start with a focused custom MVP and extend it module by module, which keeps the first cost low without locking them into a vendor. See our guide to healthcare app development cost for how scope drives price.

Security, Compliance and Interoperability Built In

A portal holds some of the most sensitive data a patient has. Security and integration are designed into the architecture from the first sprint.

Illustration of a patient record with different access levels for each user

Role-based access and isolation

Patients see only their own record. Staff and providers see what their role allows, with separate permissions for proxies and caregivers.

Illustration of a phone with a sign-in code and a security shield

Strong sign-in

Multi-factor authentication and single sign-on options, session controls and secure password recovery.

Illustration of an audit log with a magnifying glass

Encryption and audit trails

Encryption in transit and at rest, with full audit logs of who viewed or changed what, and when.

Illustration of a large shield with a check mark and compliance badges

HIPAA, GDPR and ABHA

Privacy and compliance designed in from the start. Our HIPAA-compliant app development guide explains the requirements.

Illustration of two systems exchanging data through a standards hub

HL7 and FHIR integration

Standards-based exchange with EHRs, labs and imaging, so patients see current data without duplicate entry. See our guide to FHIR integration.

Video visits and remote monitoring

Built-in telemedicine and wearable data, so care continues between visits.

AI Features We Build Into Patient Portals

AI helps patients get answers faster and helps staff handle fewer routine messages. It is designed in with human review where it matters.

Illustration of patient messages sorted by priority and routed to a care team

Message triage and routing

AI that reads incoming patient messages, flags urgent ones and routes the rest to the right team, cutting inbox load.

Illustration of an AI chat assistant answering patient questions

Patient question assistant

A chat assistant that answers common questions about appointments, bills and preparing for a visit, using your own approved content.

Illustration of a long visit note condensed into a short summary

After-visit summaries

Plain-language summaries of visit notes and results that patients can actually understand, reviewed by clinicians before release.

AI that gives medical advice can fall under device regulation. We scope that early and keep clinicians in the loop. See our guide to Software as a Medical Device.

Patient Portal Development Cost and Timeline

Cost depends on the modules you need, how many systems the portal connects to, the platforms you support and your compliance scope. Most clients launch a focused first version and add modules over time.

Starter

From $25,000

Secure sign-in, appointment scheduling, messaging and a records view, launched as a focused MVP on web or mobile. Typically 6–10 weeks.

Standard

Typically $50K–$120K

Adds EHR integration, billing and online payments, prescriptions and refills, and a mobile app on iOS and Android.

Advanced

Typically $120K–$250K+

Multi-facility portals with proxy access, wearable data, analytics and AI features, and enterprise-grade security.

Beyond development, budget for cloud hosting, SMS and email notification costs, video minutes and any EHR vendor API fees. We help you model these up front. Share your workflows and we will scope your build and price against it. You own the code, IP and data.
