EHR software development: everything you need to know

EHR software is no longer a “nice-to-have” in healthcare – it’s essential. 

But building one that’s actually usable, secure, and scalable is a different story. 

Healthcare providers, startups, and healthtech teams often jump into development too early or overcomplicate things before validating their ideas. 

The result? EHRs that fail as soon as they hit the real world. 

But, it doesn’t have to be this way. And we’ll show you why.

In this article, we’ll break down everything you need to know about EHR software development – how much it costs, the key features you need, how to do it step-by-step, and the top mistakes to avoid.

Let’s dive in!

What is EHR software and who needs it?

EHR software is the digital brain of any modern healthcare operation.

It replaces paper files, messy spreadsheets, and outdated legacy tools. 

And more importantly, an EHR connects everything from patient history to test results and prescriptions in one system.

Think of it as the foundation of your practice. If it’s weak, everything else crumbles.

You’ll be talking with our technology experts.

At its core, EHR software stores and manages a patient’s full medical history. We’re talking allergies, medications, past diagnoses, lab results, vitals, and progress notes. 

But a good EHR also helps you make better decisions.

Hospitals use it to coordinate care across departments and cut down on admin work – nearly 9 in 10 office-based physicians in the U.S. use an EHR system.

It’s not just for hospitals, though. Other organizations use (and benefit from) EHRs, like:

• Speciality clinics (mental health, dentistry, dermatology, etc.)
• Telehealth providers
• Healthcare startups and product companies
• Long-term care and behavioral health organizations
• Research institutions and diagnostic labs

If you’re in any of these groups, you don’t need an EHR just because “everyone else has one.”

You need it because it’s the single most important tool for delivering safe, efficient, and modern healthcare.

How much does EHR software development cost?

EHR software is complex. And complexity costs money.

There’s no fixed price tag, but there are clear patterns. Most EHR projects fall into one of three categories:

• Simple EHR MVP – $60,000-$100,000
• Moderate complexity EHR – $100,000-$500,000
• Enterprise-grade EHR – $500,000+

If you’re building an internal, lightweight EHR for a small clinic, that’s one thing.

But, if you’re building one that needs to support multi-location hospitals, lab integrations, telehealth, insurance APIs, and patient messaging – expect the upper range.

Let’s break down what drives cost:

• Scope – The more features you add, the more time it takes to build, test, and maintain. 
• Compliance requirements – If your product touches patient data, you’ll need to meet local and international regulations like HIPAA (US), GDPR (EU), PIPEDA (Canada), etc.
• Integrations – EHRs don’t live in a vacuum. They need to “talk” to labs, pharmacies, diagnostic tools, and sometimes even other EHRs. That means APIs, HL7, FHIR, custom connectors which adds costs.
• UX design – Bad UX in healthcare can be dangerous. Confusing flows, unclear forms, or hidden alerts lead to real risks, so you can’t cut corners here.
• Team structure – An experienced team builds faster and makes fewer mistakes. A senior-heavy team might cost more up front, but will help you avoid costly rework later. 
• Ongoing support – EHR development doesn’t stop at launch. Bug fixes, feature requests, server maintenance, performance optimization all add up.

Now, you might be thinking this is a lot of money to invest and a lot of moving parts to handle.

But, implementation costs for off-the-shelf EHRs (especially for large hospitals) can reach six-figures, too. 

A typical multi-physician practice would spend around $162,000 to implement an EHR, plus $85,000 on first-year maintenance costs.

A custom EHR isn’t always cheaper than off-the-shelf, but it gives you control, scalability, and security from day one. 

The upfront investment is high, but the long-term payoff in efficiency, trust, and growth is worth it.

Key features of EHR software

Here, we’ll cover the key features every EHR should have.

Patient record management

This is the heart of every EHR system. If it’s clunky, nothing else matters.

Patient record management is more than just storing information, it’s about making that information usable – fast, accurate, and easy to navigate.

Here are the patient records EHRs typically handle:

• Demographics
• Medical history
• Allergies and medications
• Lab results
• Imaging reports
• Vitals and progress notes
• Referral history

Each record should update in real time, across users and devices. That means doctors, nurses, and admins always see the latest data.

Here’s what a typical EHR patient management screen looks like:

source: AdvancedMD

So, how do you get it right?

Here’s what the patient record management system in your EHR should include, beyond the basics:

• Search – Add filters, tags, and full-text search. Don’t make users scroll through a PDF.
• Audit trails – Every change should be logged. Who did what and when.
• Version history – Doctors make mistakes too. Let them revert or view previous versions.
• Data structure – Use consistent naming and formats. This helps when integrating with other systems.
• Access control – Not every role needs to see everything. Set permissions by user type.

A good EHR turns chaotic files into something actionable. 

And it helps you make better decisions, faster.

Scheduling tools and patient portals

A modern EHR should do more than just hold data. It should improve how patients and providers connect. 

And that starts with scheduling.

Missed appointments cost time and money. No-show rates can reach up to 30% for some clinics, with total financial losses from no-shows reaching $150 billion per year.

Smart scheduling tools help solve this problem.

They let front-desk staff see availability in real time, reduce double bookings, and make rescheduling appointments fast and painless.

And when integrated properly, they sync with everything else – patient records, billing, and prescriptions.

Here’s what the flow might look like:

• A patient books online through a branded portal.
• They get a confirmation message instantly.
• The slot is locked into the provider’s schedule.
• A day before, they get an automated reminder.
• If they cancel, the system reopens the slot for others.

Simple and efficient – and 0 phone calls.

Now let’s talk about patient portals. These used to be basic add-ons. But now they’re essential. 

Patients expect access. They want to:

• See upcoming appointments
• View lab results
• Refill prescriptions
• Message their doctor
• Pay bills

If your system doesn’t offer this, users will notice.

Here’s what to focus on:

• Clean UI – Patients shouldn’t need a manual.
• Mobile-ready – Most users will log in on their phones.
• Two-way communication – Let users send and receive info, not just view it.
• Privacy – Protect user data with strong authentication and access controls.

Don’t underestimate this part of your EHR. 

Scheduling tools and portals are the front door. If they’re hard to use, your patients will walk away.

Build them right, and they’ll become your best retention tools.

e-prescriptions (eRx)

e-prescriptions are now the standard.

No more handwritten notes and no more pharmacy callbacks.

An eRx system lets providers send prescriptions directly to a pharmacy without printing, scanning, or faxing.

It’s faster, safer, and easier to track. Here are some of the other top benefits of e-prescribing:

source: Cleveroad

Here’s why this matters: up to 21% of handwritten prescriptions contain errors. That’s not just inconvenient, it’s dangerous. 

One older study from 2006 estimated that preventable medication mistakes killed more than 7,000 and injured more than 1.5 million people in the U.S. each year.

Transitioning to eRx helped solve that problem. In one year-long study, error rates dropped from 42.5 per 100 prescriptions to just 6.6 per 100 prescriptions after eRx adoption.

That’s why e-prescriptions have become the standard for modern EHR systems.

A strong e-prescription feature should also include:

• Drug database integration (to avoid manual entry)
• Dosage suggestions and refill options
• Interaction checks (flag allergies or contraindications)
• Pharmacy lookup
• Audit trails to track every sent prescription

If you’re in the U.S., integration with systems like SureScripts is common. In Europe, you can integrate with national systems for e-prescriptions. 

And here’s a tip – don’t overlook edge cases like controlled substances, renewals, and out-of-network pharmacies. Your system should support them or clearly flag when it can’t.

If you’re building an EHR, eRx isn’t optional anymore. It’s expected.

Get it right, and it will become one of the most-used (and most valued!) features in your product.

Interoperability

EHR software doesn’t live in a vacuum. It needs to connect with everything else.

That’s what interoperability is about – getting your EHR to talk to other systems cleanly, securely, and in real time.

It sounds simple, right? Well, it’s not.

Hospitals use one system. Labs use another. Pharmacies and insurance providers use different standards altogether. 

Without interoperability, everything breaks down.

source: CodeIT

Real interoperability means:

• Supporting HL7 and FHIR standards
• Syncing with national health databases
• Connecting to labs, imaging systems, and pharmacy networks
• Using APIs where possible
• Handling data conflicts and sync issues gracefully

This isn’t just a technical feature. It’s also a user experience issue.

If a doctor orders labs but can’t get the results back into the patient record, or if a patient updates their allergy info in one portal and it doesn’t reflect in the main record, your EHR misses the mark.

But here’s the truth: most legacy systems, including EHRs, weren’t built to share. That’s your edge.

Modern EHRs must be designed for connection from day one. That includes:

• Structured, normalized data
• Real-time syncing
• Error handling and version control
• Secure authentication and access protocols

The payoff is huge. 

Interoperable systems reduce admin time, improve care coordination, and unlock better patient outcomes.

Patients don’t care which system stores their data. They care that their doctor has the full picture. 

And your EHR should make that happen.

Medical billing tools

Billing shouldn’t just be a side feature. It’s a core workflow.

If your EHR doesn’t support accurate, fast billing it creates friction. 

Billing tools in EHR software need to handle everything from insurance checks to invoice generation. And every step should be automated as much as possible.

Here’s what a strong billing feature set includes:

• Insurance verification
• CPT/ICD-10 coding support
• Claim generation and tracking
• Patient invoicing
• Co-pay and deductible management
• Payment processing
• Automatic follow-ups on unpaid claims

Billing errors are expensive. One misplaced code can delay payments for weeks. 

If you’re building for the U.S. market, that’s a constant concern. Mistakes mean rejections and rejections cost money.

Every EHR should support multiple payer types – private insurers, Medicare/Medicaid, self-pay – and automate as much coding as possible.

If a doctor has to pick every billing code manually, you’re doing it wrong.

Your billing tool also needs to reflect real-world edge cases like:

• Denied claims
• Secondary insurance
• Split billing for shared visits
• Time-based charges for therapy or consultations

And don’t forget the patient side. 

Billing should be transparent. Your EHR should let users view invoices, see what insurance covers, and pay directly through the portal.

People hate surprises with healthcare costs and a clear billing process will help you build trust.

The goal here isn’t to “add billing.” It’s to make it feel like part of the care experience.

And if they’re done right, your billing tools will improve revenue and save you hours of admin work every week.

Reporting and analytics

You can’t improve what you don’t measure. And in healthcare, the stakes are too high to rely on guesswork.

Reporting tools help teams make better decisions, fast. 

Whether it’s spotting a trend in patient outcomes or tracking claim denials, good data saves time and money.

If your team has to pull stats from spreadsheets, email files back and forth, and lose hours each week building basic reports – you’re already behind.

But, with a built-in dashboard that tracks key metrics like patient flow, no-show rates, and billing issues you can act on insights in real time.

Strong reporting tools in EHR systems should include:

• Clinical performance metrics
• Patient volume and retention tracking
• Staff utilization reports
• Billing and revenue cycle insights
• Medication adherence tracking
• Population health overviews

And remember, different roles need different views. 

Doctors will want outcome trends. Managers and admins care about revenue and workflow bottlenecks. Make sure your EHR is built for both.

Here’s what you need to get it right:

• Custom filters – By provider, diagnosis, date range, insurance type.
• Visual dashboards – Charts, heatmaps, drill-downs.
• Export options – PDF, CSV, API for external tools.
• Real-time updates – No one wants to act on last week’s data.

And don’t stop at surface metrics. Use the data to trigger actions.

For example, if there’s a spike in cancellations, your EHR should trigger an alert. Or if claims are delayed for over 30 days, it should flag them for billing.

Analytics should do more than report. It should support key decisions.

If your EHR can surface issues before they become problems, you’ve built something your team will rely on. 

Clinical decision support systems (CDSS)

Doctors don’t need more noise. They need clarity. 

That’s where clinical decision support systems (CDSS) come in.

CDSS help providers make better, faster, safer decisions when it matters most. They don’t replace medical judgment, they guide it.

Think of CDSS as a smart layer inside your EHR. One that spots risks, offers suggestions, and prevents costly errors.

Here’s a quick overview of how CDSS can be structured in EHR systems:

source: Jelvix

A good CDSS should:

• Alert for allergy conflicts
• Flag dangerous drug interactions
• Recommend diagnostic tests based on symptoms
• Support preventive care reminders
• Provide treatment suggestions from clinical guidelines
• Offer risk assessments (e.g. fall risk, readmission risk)

But having too many alerts can backfire. 

Alert fatigue is real. If doctors get too many irrelevant warnings, they start ignoring all of them.

The key is relevance. Build your CDSS logic around actual usage patterns, prioritize high-risk situations, and let end-users customize alert sensitivity where possible.

Also: context matters.

A flag saying “Possible interaction with Drug X” is useless without details. 

A better version is: “Drug X and Drug Y can increase bleeding risk. The patient is also on aspirin. Consider alternatives.”

That’s your bar. Build a system doctors want to rely on, not one they tolerate.

It’s one of the most impactful features you can include in your EHR.

How to build EHR software

Next, we’ll give you a step-by-step guide on how to build EHR software.

Validate your business case first

Don’t just start building your EHR right away.

Too many people rush into development with assumptions, not evidence. Your idea might feel solid, but feelings don’t build successful software.

And that’s why you need to validate your business case first.

Start with this question: Who is this for, and what specific problem are we solving?

Let’s say you want to build a specialized EHR for dermatology clinics, for example.

You might be sure the idea is strong, but until you interview actual clinic owners and practitioners, you won’t know if it’s actually worth building.

Maybe half of the features you’ve had in mind aren’t needed and the other half need major changes.

That’s why real-world validation is key before writing a single line of code. It saves time and money and prevents major headaches down the road.

Here’s what real validation looks like:

• Talk to your users – Not once, regularly. Ask about their workflows, pain points, and what’s missing in their current tools.
• Watch them work – Sit in on appointments and shadow admin staff. See what they actually do, not just what they say.
• Run problem interviews – Focus on frustrations, not solutions. Let them vent, the gold is in the details.
• Map their journey – Understand where your EHR fits into their daily process. You might be overestimating your role.

You should always build based on what users prove they need.

Validation also means pressure-testing your pricing model. If you can’t explain the ROI clearly, don’t expect clinics or hospitals to sign off.

If it doesn’t save them time, reduce risk, or increase revenue – it won’t stick.

And remember, leave your ego at the door. Validation isn’t about being right, it’s about getting it right.

Start there, and everything you build after will have a reason to exist.

Identify must-have features and integrations

Don’t build everything. Build only what matters and solves your specific problem(s).

When it comes to EHR software, feature creep is one of the biggest threats.

It slows down development, bloats your product, and it usually means you’re guessing instead of prioritizing.

Start by defining your core workflows. What actions will your users repeat every day? Those are your must-haves.

Focus on features that help your users do their jobs better today. Not three years from now.

Use this approach:

• Map your user journey – From login to discharge. Which tasks matter most?
• Score features by impact and frequency – A flashy report builder won’t matter if nobody uses it.
• Ask this often – Does this feature solve a real problem, or does it just look good on paper?

Next up: integrations.

EHRs don’t work in isolation. They have to plug into the healthcare ecosystem around them.

And you don’t want to be working with 5 disconnected tools if you can help it.

Here’s the key: choosing integrations isn’t just a technical decision, it’s a strategic one. You need to pick integrations that make your EHR more useful and harder to replace.

Research compliance requirements

In healthcare, compliance isn’t optional.

If your EHR isn’t built for privacy, security, and regulation – you’re already way behind. Worse, you’re putting yourself and your patients at risk.

This isn’t about checking boxes. It’s about protecting real people and their medical records.

Of course, you need to know which laws apply to you – if you’re in the U.S., it’s HIPAA. And in the EU, it’s GDPR. Other countries and regions have local laws, too.

Each has its own definitions of patient data, retention policies, and breach response rules. You need to understand before you write a single line of code.

Let’s take a closer look at HIPAA first. Here’s a brief overview of how it applies to software development:

Key HIPAA rules that impact software development: overview

One catastrophic breach and you could be on the hook for an 8-figure sum – the record HIPAA settlement was $16 million.

So, if you’re in the U.S. or want to target the U.S. market, make sure your EHR is HIPAA-compliant from the start.

Then, there’s GDPR.

While it’s not a healthcare-specific law, GDPR explicitly protects health, genetic, fitness, and wellbeing data.

source: TDS Archive

So, how do you make sure your EHR is compliant with these laws?

Here’s what it should have:

• Encryption – Encrypt data both at rest and in transit.
• Access controls – Only authorized users should see sensitive data.
• Audit logs – Track every access, edit, and deletion.
• Data backups – You must be able to recover records in case of failure or breach.
• Authentication – Multi-factor, not just passwords.

Security isn’t something you patch later. It has to be part of your EHR’s architecture.

If you’re collecting health data, you’re handling some of the most sensitive data out there.

Compliance might slow you down at first. But it saves you from rebuilding, losing clients, or facing legal action.

So, bake it into your EHR from day one.

Design the user experience (UX)

In healthcare, bad design has consequences.

Your EHR needs more than clean visuals. It needs smart, fast, and intuitive workflows. Every click matters, and every second saved improves patient outcomes.

Good UX in EHRs means fewer distractions, clearer information, and workflows that match the way real people work. 

Here’s what you need to get right:

• Navigation should feel obvious – If someone needs training just to find a patient record, your EHR failed.
• Actions should match habits –  Nurses, doctors, and admins each have different workflows. Build for all of them.
• Forms should adapt – Don’t show all fields all the time. Show exactly what’s needed, when it’s needed.
• Minimize clicks – The gold standard? One task per screen.
• Support mobile use. Many providers use phones to access EHRs. Design accordingly.

For example, notes should be quick to enter and easy to review, while filling prescriptions should take seconds, not minutes.

Design isn’t just for looks. In EHR software, good UX reduces risk and speeds up care.

And that’s why you need to get it right.

Build and launch your EHR software

Once you’ve validated your idea, prioritized the right features, and locked in compliance – it’s time to start building your EHR.

Now, we won’t get too technical here – we’ll just cover some of the best practices you should follow for successful development.

First, you’ll need to break development into phases. And the best way to do it is with an agile development methodology like Scrum.

Scrum is based on short (2-4 week) iterations called sprints which act like mini-development cycles. 

And this iterative approach lets you build even the most complex software without overwhelming your development team.

Next, make sure to double down on QA and testing.

And don’t wait until the end to start testing. Finding and fixing bugs at the start of development can be up to 100x cheaper than fixing them post-launch:

Use automated testing for repetitive tasks and combine it with manual testing for edge cases.

Also, document everything from workflows to APIs. EHRs are built to last, so clear, thorough documentation will pay off over time.

And when you launch, keep it tight:

• Roll out to a test clinic or closed beta group
• Monitor usage daily
• Track the most-used flows
• Capture drop-off points
• Prepare a backlog of quick wins and fixes

Your job after launch isn’t (just) to celebrate. It’s to listen to feedback, which we’ll cover in more detail next.

Monitor usage and collect real feedback

Your EHR is live, congratulations!

Well, now the real work begins.

Your first version is just that – a first version. The best EHRs are the ones that grow with their users. 

And you can get there by watching your users closely, interviewing them often, and never assuming you’re done.

You need both hard data and honest, unfiltered feedback.

Here’s what you should track:

• Most used features
• Drop-off points
• Time to complete key tasks
• Error frequency
• User sessions and active days

Set up product analytics from day one. Heatmaps, event tracking, and usage logs will be your best friends.

Then, pair that with qualitative user input:

• Run regular user check-ins
• Send short in-app surveys
• Open a feedback channel 
• Ask what frustrates them, not just what they like

What you need to do is set up a feedback loop.

A feedback loop is key if you want to continuously and systematically collect, analyze, and act on user feedback.

And you’ll get a much deeper understanding of their needs, pain points, and what’s working (and what isn’t).

So, post-launch, you shouldn’t just focus on fixing bugs. You also need to learn what actually drives value and remove any friction users experience.

Every small win matters. A two-click shortcut, a clearer warning message, 3 seconds saved per task.

Don’t wait months to ship changes. Small, frequent updates will show that you’re actually listening. 

And this will build trust faster than a perfectly optimized v2 ever could.

Common mistakes to avoid in EHR software development

Even the best team can get EHR development wrong. And one wrong move doesn’t just slow you down, it can even sink your project before it even really gets going.

Let’s break down a few of the most damaging mistakes we’ve seen.

First up, skipping discovery. This is the big one. 

You might be in love with your idea and dive straight into building. No research. No user interviews. Just assumptions.

It never works.

You need to make sure it’s actually worth building. For example, if you’re a small clinic and you have standard workflows, you likely don’t need a custom EHR at all.

You can’t fix a product no one needs. So, validate your idea first and make sure developing a custom EHR makes sense in the first place.

Next, it’s scope creep caused by overbuilding before launch.

Trying to solve every problem in version one is a common trap. 

You add features. Then more features. Soon you’ve built a monster that’s hard to test, harder to maintain, and impossible to ship on time.

Trying to build the most complete EHR on the market is a fool’s errand, since those companies have a massive head start.

Strip your EHR down to what matters most to you or your clients – and make sure it fully solves the key problem.

Finally, it’s treating compliance as an afterthought.

Compliance isn’t something you can bolt on later. You shouldn’t push security to “phase two.” It always backfires. 

Data handling, access control, encryption – if you don’t build these early, you’ll be rebuilding later.

HIPAA, GDPR, local laws, whatever applies to your region, plan for it from day one. The cost of skipping it is always higher.

Avoiding these pitfalls is what separates a successful EHR from a failed one. 

Stay focused, build only what users actually need, and treat compliance as a top priority.

And that’s how you’ll build an EHR that actually works.
