Explore the Wider Healthcare Practice

An EHR connects to the systems around it, so these related healthcare services cover what an EHR platform depends on.

“91% of office-based physicians and more than 99% of hospitals use a certified EHR, yet most still cannot share records cleanly.” — ONC

Adoption is finished; interoperability is not, so EHR software development is now about building systems that actually exchange data, not just store it.
The Basics

What EHR Software Development Is

EHR software development engineers the systems clinicians use to record and exchange patient information. EHR and EMR software must meet HIPAA, ONC certification, and interoperability standards.
EHR vs EMR

EHR vs EMR

An EMR is the chart within one practice; an EHR is the record that follows the patient across providers and systems.

Successful Projects

Clinical charting

The core EHR functionality clinicians use to document a visit, built for speed over clicks, so charting takes seconds of attention rather than minutes away from the patient. We design templates, shortcuts, and structured fields around how each specialty actually documents, because a chart that fights the clinician is a chart that gets abandoned.

E-prescribing

E-prescribing with EPCS for controlled substances, connected to pharmacy networks, so a prescription leaves the visit electronically instead of by phone, fax, or paper. Interaction checks and formulary data surface at the point of prescribing, and controlled-substance workflows meet the identity and audit requirements the DEA imposes on electronic prescribing.

CPOE and orders

Computerized provider order entry for medications, labs, and imaging, with decision support that checks each order against the patient record before it is placed. Order sets and protocols speed routine care, while alerts catch contraindications early, so the record actively supports the decision rather than passively storing it after the fact.

Lab and results

Lab and imaging orders that flow out and come back into the record with context, so a clinician reads a result against the patient’s history, not in isolation. Results route to the ordering provider, flag abnormal values, and attach to the right encounter, so nothing falls through the gap between order and follow-up.

Billing and coding

Charge capture, coding, and claims wired into the clinical record, so billing follows documentation automatically rather than as a separate task after the visit. Codes are suggested from the encounter, claims are checked before submission, and the revenue cycle stays connected to care instead of running as a disconnected back-office process.

Scheduling

Appointment scheduling and registration built into the EHR system, so the front desk and the clinical record share one view of every patient and visit. Reminders reduce no-shows, waitlists fill cancellations, and eligibility checks happen at booking, so the schedule reflects reality rather than a best guess that unravels by mid-morning.

Patient portal

A patient portal so patients can view records, results, and messages, connected to the same EHR data clinicians use rather than a separate copy that drifts. Patients book appointments, request refills, complete intake, and message the care team, which cuts phone volume for staff and keeps patients engaged between visits.

Interoperability

HL7 and FHIR interfaces that make the EHR exchange data with other healthcare systems, so records move with the patient instead of being trapped in one system. We build the interfaces, map the data models, and support the standards that let your EHR send, receive, and reconcile records across the wider network.

Telehealth

Virtual visits connected to the EHR so care and record stay together, with notes and orders from a video visit landing in the same chart as an in-person one. Scheduling, documentation, and billing work identically across visit types, so telehealth is a channel within the record rather than a separate tool clinicians juggle.

Analytics

Reporting and analytics across the healthcare data in the record, so a healthcare organization can measure quality, track outcomes, and meet reporting requirements. Dashboards surface population trends, quality measures, and operational metrics from the same data clinicians enter, turning the record into a source of insight rather than only a store of history.

Mobile EHR

A mobile EHR so clinicians reach the record at the point of care, whether at the bedside, on rounds, or between facilities, without returning to a workstation. The mobile experience is built for real clinical use rather than a shrunk-down desktop screen, so charting, orders, and results work on a phone or tablet.

Custom EMR modules

Custom EMR and EHR modules for a specialty a packaged system ignores, from behavioral health to oncology, built to the workflow that specialty actually runs on. When an off-the-shelf record forces a specialty into fields designed for general practice, we build the module that fits, so the software serves the care rather than constraining it.

Interoperability

Interoperability and Standards

An EHR that cannot exchange data is a silo, so we build interoperability and ONC certification into the system from the start.
HL7 and FHIR
ONC certification

Data

The standards

Data exchange runs on standards, so the EHR speaks them natively.
  • FHIR: modern APIs so the EHR shares records with apps and other systems.
  • HL7 v2: legacy interfaces where older healthcare systems require them.
  • Interfaces: clinical data exchanged across EHRs, labs, imaging, and other systems.
  • APIs: FHIR APIs built for secure access to healthcare data.

The requirement

A certified EHR is what lets providers meet federal programs.
  • Certification: built to ONC Health IT Certification criteria from the start.
  • Standards: US Core Data for Interoperability supported in the record.
  • Compliance: EHR capabilities aligned with applicable ONC certifications.
  • Testing: required workflows validated against certification criteria.
Image slot 400

The network

An EHR joins the wider exchange, not just its own walls.
  • Exchange: health information exchange connections so records follow the patient.
  • TEFCA: alignment with national exchange frameworks.
  • Exchange: patient records shared securely across connected organizations.
  • Matching: incoming records matched to the correct patient across systems.

Large healthcare systems get an EHR that spans departments and integrates across facilities.
02

Clinics and practices

Clinics and small practices get an EMR or EHR sized to them, not an enterprise system they cannot run.
03

Digital-health companies

Digital-health companies build the EHR platform behind their product, so they own the system.
04

Specialty providers

Specialty practices get custom EHR solutions tuned to a workflow packaged systems ignore.
How We Work

From EHR Requirements to a Live System

An EHR touches every clinician and every record, so we build it in stages that reach a certified, live system rather than a demo, throughout the software development process.
Step 1

Discovery

We map workflow, EHR requirements, compliance scope, and the systems the EHR must connect to. This is where scope and regulatory reality become clear, so nothing surfaces late.
Step 2

Architecture

We design the data model, interoperability layer, and security before feature work, because architecture determines whether the EHR scales and exchanges data.
Step 3

Build

We develop module by module in sprints, each demonstrable as it lands, so requirements sharpen while changes are cheap.
Step 4

Integrate

We connect labs, pharmacy, billing, and other systems through HL7 and FHIR, validating each against real messages.
Step 5

Validate and certify

We run development and testing across modules, validate HIPAA controls, and confirm ONC certification readiness before go-live.
Step 6

Launch and support

We support the EHR in production and add functionality as the healthcare organization grows, because an EHR is a long-running system, not a one-time project.

Cost Factors

What Drives Cost and Timeline

The average cost of an EHR system depends on whether you build or customize, the modules, and the compliance scope, so it helps to know the drivers before budgeting.

Build or customize

Building a custom EHR from scratch carries more up front than customizing a platform, but no per-seat licensing. The average cost of EHR development tracks scope more than anything.

Modules and functionality

Each module, from CPOE to analytics, adds EHR functionality and cost. A focused EMR is a smaller build than a full EHR platform.

Interoperability and certification

HL7, FHIR, and ONC certification add fixed engineering that a non-certified system avoids.

Compliance

HIPAA and healthcare regulations are non-negotiable scope. A precise estimate follows discovery.

Building an EHR or EMR System

Tell us whether you want to build an EHR from scratch or modernize an existing one, and we scope an approach.
Questions You May Have

What is EHR software development?

EHR software development is the engineering of the systems clinicians use to record, retrieve, and exchange patient information: charting, orders, results, e-prescribing, and billing. EHR and EMR software must meet HIPAA, ONC certification, and HL7/FHIR interoperability, so development is as much about compliance and data exchange as features.

What is the difference between EHR and EMR?

An EMR is the digital chart within a single practice, while an EHR is the broader record designed to follow the patient across providers and exchange data. EMR software development and EHR software development overlap, but an EHR adds the interoperability an EMR or EMR system lacks.

Should we build an EHR from scratch or customize one?

You can build your own EHR as a custom EHR solution, or customize an existing EHR platform. Building an EHR from scratch fits a specialty workflow and carries no per-seat licensing, while customizing is faster up front. The choice depends on how far your workflow diverges from a packaged system.

What is the average cost of EHR software development?

The average cost of an EHR depends on whether you build or customize, the number of modules, and compliance scope. A focused EMR is far less than a full custom EHR platform, and interoperability and ONC certification add fixed engineering. A precise estimate of the average cost of an EHR system follows a discovery phase.

Is a custom EHR HIPAA-compliant and ONC-certified?

It has to be. HIPAA compliance means encryption, role-based access, and audit logging, while ONC certification means the EHR meets federal Health IT Certification criteria. We build both into the system from the first sprint rather than adding them later.

What technology stack do you use for EHR development?

We build EHR systems in Java, Ruby on Rails, Python, and Node.js, with React front ends and PostgreSQL, on HIPAA-eligible AWS or Azure. Interoperability uses FHIR and HL7, so the EHR exchanges data with other healthcare systems.

How do you make an EHR interoperable?

An EHR is made interoperable through HL7 and FHIR interfaces, US Core Data for Interoperability, and health information exchange connections. Interoperability is designed into the data model at the architecture stage, because retrofitting it into an EHR built as a silo is far harder.

What is your EHR software development process?

Our EHR software development process moves through discovery and EHR requirements, architecture, build, development and testing, certification, and launch. These development stages exist because an EHR is a regulated clinical system that cannot ship on an untested build.

Do you build EMR software as well as EHR?

Yes. We handle EMR software development for single-practice charting and full EHR development for records that span providers. Many projects are custom EMR and EHR builds that start as an EMR and grow into an interoperable EHR.

Can you modernize our existing EHR or EMR system?

Yes. We add new EHR functionality, re-architect an aging EHR for scale, and migrate data from a legacy EMR system. Modernization delivers a modern EHR without the disruption of replacing everything at once.

Do you build advanced EHR features and aspects of EHR beyond charting?

Yes. Beyond charting we build the advanced EHR aspects that mature systems need: decision support, analytics, patient engagement, and AI documentation. These aspects of EHR are what separate a basic record from a modern EHR clinicians rely on.

Do you handle EHR implementation and integration too?

Yes. EHR software implementation and EHR integration are covered in depth on their own pages, and we deliver both alongside development. This page focuses on building and customizing the EHR itself.

Can you develop EHR systems and EHR and EMR systems for a group?

Yes. We develop EHR systems and connected EHR and EMR systems for groups and networks, so multiple facilities share one interoperable record. Whether you need an EHR or EMR system for one site or many, we build to the setting.

What makes a reliable EHR software development partner?

A reliable EHR software development partner has a track record in regulated systems, real interoperability and ONC-certification experience, and healthcare software developers who understand clinical workflow. An EHR development company should show how it handles compliance and data exchange, not just a feature list.

Is there a guide to EHR software development we can follow?

This page works as a short guide to EHR software development, but every build differs, so a proper approach to EHR starts from your EHR requirements. We turn those into a concrete scope during discovery, and can build the EHR system or an EHR solution around them.

Do you work as a development company or embed with our team?

As an EHR software development company and healthcare software development company, we deliver EHR software development services end to end, or embed EMR software developers and a development team alongside yours through team extension as your EHR software development partner.
