To choose a custom healthcare software development company, check five things: proven work with health data under GDPR or HIPAA, integration with your EHR through HL7 FHIR, a secure and audited cloud setup, clinical user testing, and a support contract that covers the system for years. Ask for references from similar projects and test them with a paid discovery phase.
Key takeaways
- Health data is a special category under GDPR, so the vendor must design for consent, access logging, data minimisation and EU or Indian data residency from day one.
- If the software has a medical purpose, it may be a medical device under the EU Medical Device Regulation, which changes the whole development process.
- Integration is usually the hardest part. Ask which EHR systems the vendor has connected to and how they use HL7 FHIR.
- Security must be shown, not claimed: penetration test reports, encryption, audit trails and incident response plans.
- Budget for the full lifecycle. Hosting, monitoring, security updates and regulatory changes continue after launch.
When does custom healthcare software make sense?
Custom software makes sense when off-the-shelf products cannot support a key workflow, cannot integrate with your systems, or cannot meet local data rules. If a certified product already fits most of your needs, configuring it is usually cheaper and lower risk.
Typical custom projects include:
- Patient portals and apps for booking, messages, test results and digital forms.
- Telehealth and remote monitoring with video consultations and data from home devices or wearables.
- Clinical workflow tools that sit beside an EHR, such as referral management, care planning or triage.
- Integration layers that connect EHR, lab, imaging, pharmacy and billing systems.
- Analytics and AI for capacity planning, risk scoring or image analysis.
- Admin systems for scheduling, staffing, inventory and claims.
| Off-the-shelf product | Custom software | |
|---|---|---|
| Time to go live | Shorter | Longer, built in phases |
| Fit with workflows | You adapt to the product | Built around your workflows |
| Compliance work | Vendor certifies the product; you configure it | You and the developer own compliance and documentation |
| Integration | Limited to supported connectors | Any system with an API or standard interface |
| Long-term cost | Licence fees, less control over roadmap | Build cost plus ongoing maintenance and hosting |
Which regulations must the vendor understand?
The vendor must know the rules in every market where the software will be used. For Nordic, EU and Indian buyers that usually means GDPR or India's DPDP Act, national patient data laws, and the EU medical device rules. US projects add HIPAA.
GDPR and national patient data laws
Under GDPR, data concerning health is a special category of personal data, and processing it is prohibited unless a specific exception applies. In practice the vendor must support a clear legal basis, data minimisation, role-based access, logging of who viewed which record, and data processing agreements with every sub-processor. Sweden adds the Patient Data Act (patientdatalagen), and other Nordic countries have similar national laws. Our GDPR compliance service covers the controls involved.
EU Medical Device Regulation
Software that diagnoses, monitors or guides treatment can qualify as a medical device under Regulation (EU) 2017/745. If it does, you need a quality management system, risk management, clinical evaluation and often a notified body. The European Commission's medical devices regulation pages list the current guidance. Ask the vendor whether they have built software under the MDR and which standards (for example IEC 62304 for software lifecycle) they follow.
European Health Data Space
The European Health Data Space (EHDS) Regulation entered into force on 26 March 2025. Key parts apply from March 2029, starting with cross-border exchange of patient summaries and ePrescriptions, and medical images, lab results and discharge reports follow from March 2031. Software that stores or exchanges EHR data in the EU should be designed with these interoperability requirements in mind.
India's DPDP Act
For Indian deployments, the Digital Personal Data Protection Act, 2023 sets rules for consent, purpose limitation and data principal rights. Hospitals and health-tech firms connecting to the national digital health ecosystem (ABDM) also need to follow its integration and consent standards.
HIPAA for US projects
HIPAA's Privacy and Security Rules apply to covered entities and their business associates. If you host on AWS, AWS requires a Business Associate Addendum and protected health information may only be stored in HIPAA-eligible services. A vendor claiming to be "HIPAA certified" is a warning sign: there is no official HIPAA certification for software companies.
Why does interoperability matter so much?
Because a healthcare app that cannot read and write data in the EHR creates double entry and safety risks. Interoperability is often the largest single piece of work in a project.
HL7 FHIR is the main standard for exchanging healthcare data through modern APIs. Many hospitals still run HL7 v2 messages, DICOM for imaging and proprietary interfaces next to it. Ask the vendor:
- Which EHR systems they have integrated with, in which countries.
- Which FHIR version and national profiles they have used.
- How they handle HL7 v2, DICOM and terminology standards such as SNOMED CT or ICD-10.
- How they test integrations without using real patient data.
What security evidence should you ask for?
Ask for documents, not promises. A credible healthcare developer can show how it protects data in development, testing and production.
- Secure development: code review, dependency scanning, secrets management and threat modelling for new features.
- Testing: recent independent penetration test results for similar systems, and how findings were fixed.
- Encryption: in transit and at rest, with clear key management.
- Access control: single sign-on, multi-factor authentication, least privilege and full audit trails.
- Test data: synthetic or anonymised data in development and test environments.
- Operations: logging, monitoring, backups, disaster recovery tests and an incident response plan with named contacts.
- Certifications: ISO 27001 for the vendor's own information security, and ISO 13485 if they work on medical devices. Ask for the certificate and its scope.
How to evaluate a custom healthcare software development company
Use a weighted scorecard and a short paid discovery phase. That gives you real evidence of how the team works before you sign a large contract.
| Criterion | What good looks like | Red flags |
|---|---|---|
| Healthcare references | Similar projects you can call, in your region | Only generic software references |
| Compliance knowledge | Clear answers on GDPR, MDR, DPDP or HIPAA for your case | "HIPAA certified" claims, vague answers |
| Integration | Named EHR integrations and FHIR experience | "We can integrate with anything" |
| Clinical UX | Usability tests with clinicians and patients | Design reviewed only by managers |
| Delivery | Short iterations, demos, visible backlog | Big upfront spec, long silent periods |
| Hosting and operations | Clear plan for cloud, monitoring, backups and on-call | "Your IT will host it" |
| Ownership | You own the code, data and documentation | Proprietary frameworks you cannot leave |
12 questions to ask vendors
- Which healthcare systems have you built, and can we speak to two of those customers?
- Does our planned software qualify as a medical device, and how would that change your process?
- Where will patient data be stored and processed, including backups and logs?
- Which sub-processors will touch the data, and in which countries?
- Which EHR systems have you integrated with, using which standards?
- How do you test with clinicians, and how often?
- Can we see a recent penetration test summary for a comparable system?
- How do you manage access to production, and who on your team has it?
- What is your incident response process and notification time?
- Who owns the source code and IP, and what happens if we change supplier?
- What does support cost after launch, and what SLA do you offer?
- How will you keep the system compliant as regulations change?
What drives the cost?
Costs vary widely, so ask for estimates per phase instead of comparing headline prices. The main drivers are:
- Number of user groups (patients, clinicians, admins) and platforms (web, iOS, Android).
- Number and complexity of integrations, especially with older EHR interfaces.
- Regulatory class: software under the MDR needs far more documentation and testing.
- Security and audit requirements, including external testing.
- Data migration from legacy systems.
- Hosting, monitoring and support for the life of the system.
A discovery phase of a few weeks that produces user flows, an architecture, a compliance assessment and a phased estimate is the cheapest way to reduce this uncertainty.

Frequently asked questions
What does a custom healthcare software development company do?
It designs, builds, integrates and maintains software for healthcare providers, insurers and health-tech firms. Typical work includes patient apps, telehealth, clinical workflow tools, EHR integrations and analytics, built to meet health data and security rules.
Is custom healthcare software a medical device?
It can be. Under the EU Medical Device Regulation, software intended to diagnose, prevent, monitor or treat disease may qualify as a medical device. Booking, billing and general admin software usually does not. Get a regulatory assessment early, because the answer changes the development process.
Can a healthcare app be GDPR and HIPAA compliant at the same time?
Yes, but they are different laws with different requirements. Design for the stricter rule in each area, keep data location under control, and document how each requirement is met. Compliance also depends on how you operate the system, not only on the code.
How long does custom healthcare software take to build?
A focused patient or clinician app can reach a first release in a few months. Systems with many integrations, or software regulated as a medical device, often take a year or more. Phased delivery lets you put a smaller first version into use earlier.
Should we choose an onshore or offshore development partner?
Many Nordic and EU buyers use mixed teams: local architects and product owners with delivery capacity in India. What matters is that patient data access is controlled, that data stays in approved regions, and that contracts cover GDPR roles and sub-processors.
