This guide helps healthcare SaaS teams compare development partners for connecting their products to the EHR systems used by different customers.
Your healthcare SaaS product works well for its first customer. Then a new prospect asks whether it connects to their EHR. Another prospect uses a different system and wants to send information back into the patient chart.
Suddenly, integration becomes part of the product roadmap. Your team needs to decide which connections to build first, how to handle differences between customer environments, and who will maintain everything after launch.
Several companies with a California presence can help with healthcare SaaS EHR integration. Yalantis, TATEEDA, Sidebench, OSP Labs, and Bitcot offer different combinations of healthcare product development, EHR connectivity, and data exchange services.
You might be looking for an integration partner because:
- A prospective customer requires an EHR connection. Your product needs to exchange information with the system the organization already uses.
- Each new deployment requires extensive custom work. Your team wants a more repeatable way to onboard customers.
- Your existing integrations are difficult to maintain. Failed messages, changing interfaces, or customer-specific configurations consume engineering time.
- Your product needs to support another workflow. You may need to retrieve clinical information, submit data to an EHR, or let users open your application from within the EHR.
- Your team is planning for growth. You need to decide what can be shared across connections and what must be configured for each customer.
The right partner depends on your product, target customers, required data, and the EHRs you need to support. The five companies below provide different places to start.

Yalantis: Multi-EHR Connections for Healthcare Products
Yalantis is a software development company with a Long Beach office. Its healthcare work includes application development, interoperability engineering, and connections between healthcare products and EHR systems.
The company may be a good fit for a SaaS team that already has a product and needs to make its integrations easier to extend. That can involve more than adding another API: the application may also need to account for different data structures and business rules across EHRs.
In its Healthfully case study, Yalantis describes connecting a California-based patient engagement platform to multiple EHRs, including Cerner, athenahealth, NextGen, and Greenway Health. The company says it redesigned parts of the integration architecture so individual connections could operate separately and the platform could accommodate additional systems.
| California office | 1080 Ximeno Ave, Long Beach, CA 90804 |
| Relevant work | Healthcare product development, EHR integration, and interoperability |
| EHRs named in the Healthfully project | Cerner, athenahealth, NextGen Healthcare, and Greenway Health |
| Integration methods | HL7 and FHIR in the Healthfully work; other methods depend on the project |
| First scope to discuss | One product workflow across the EHRs used by your current or prospective customers |
| Homepage | yalantis.com |
Best fit: A healthcare SaaS company that wants to extend an existing product across multiple EHR environments.
Worth discussing: Ask how the team would separate shared integration components from EHR-specific logic, and how it would test changes before releasing them to customers.
TATEEDA: EHR Integration Around Your SaaS Product
TATEEDA is a San Diego healthcare software development company that helps organizations build, update, and connect healthcare applications. Its work covers clinical software, patient portals, medical billing, staffing applications, and other products used in healthcare.
For a SaaS company, the integration is often part of a larger product decision. Your team may need to add an EHR connection while also updating user permissions, improving an existing interface, or preparing the application for additional customers.
TATEEDA’s healthcare SaaS development services address the product and its integration layer together. The company describes working with FHIR and HL7 interfaces, customer-specific credentials and endpoints, and monitoring for failed data exchanges. Its EHR development services cover systems such as Epic, Oracle Health/Cerner, athenahealth, and Allscripts/Veradigm.
A project can begin with a specific workflow. For example, a patient engagement product might first need to retrieve appointment information from one customer’s EHR. The team can then examine what would change when another customer uses a different system or has different access requirements.
| California office | 7220 Trade Street, Suite 103, San Diego, CA 92121 |
| Relevant work | Healthcare SaaS development, EHR integration, application modernization, and support |
| EHRs named in its services | Epic, Oracle Health/Cerner, athenahealth, and Allscripts/Veradigm |
| Integration methods | FHIR, HL7, APIs, and SMART on FHIR where supported |
| First scope to discuss | One customer, one EHR, and a defined product workflow |
| Homepage | tateeda.com |
Best fit: A healthcare SaaS company that needs custom EHR connections and wants the integration work coordinated with its wider product roadmap.
Worth discussing: Identify the first customer workflow, the information it needs, and the support responsibilities before deciding how to extend the connection to additional customers.
Sidebench: Product Design for EHR-Connected Workflows
Sidebench is a Los Angeles product development company that combines strategy, design, and software engineering. Its healthcare work includes applications and integrations for clinical and patient-facing workflows.
Sidebench can be relevant when your team needs to decide how the integration should feel to the person using the product. For example, should a clinician open your application from within the EHR, or should information move between the systems in the background? The answer can affect both the interface and the technical scope.
The company says it has built integrations with Epic, Cerner, athenahealth, CentralReach, and CharmEHR. In its published discussion of EHR integration work, Sidebench also describes Epic work for Hoag and an athenaOne integration for an unnamed longevity technology client. These are separate examples, so a buyer should ask which experience is closest to the proposed SaaS workflow.
| California presence | Los Angeles, California |
| Relevant work | Product strategy, UX design, healthcare applications, and EHR integration |
| EHRs named in its materials | Epic, Cerner, athenahealth, CentralReach, and CharmEHR |
| Integration focus | Connections shaped around the product and its users’ workflows |
| First scope to discuss | A clinician or patient workflow that needs information from an EHR |
| Homepage | sidebench.com |
Best fit: A healthcare SaaS team that needs to develop the user experience alongside its EHR connection.
Worth discussing: Ask which design and research activities are included in the proposed project, especially if you already have a defined workflow and need a focused integration.
OSP Labs: Healthcare Data Exchange and Custom Interfaces
OSP Labs is a healthcare software development company with a Los Angeles office. Its services cover EHR integration, clinical data exchange, billing systems, and other healthcare applications.
OSP can be useful when your SaaS product depends on moving clinical or administrative information between systems. The work may involve examining the data available from each source, mapping it to your product, and deciding how to handle records that are incomplete or cannot be processed.
In one interoperability project, OSP describes building an application to connect multiple EHR systems for a healthcare provider. In a separate project, the company describes using Mirth Connect to move clinical and administrative data from Epic to Cerner. The latter is an example of data exchange between two EHR systems, rather than a SaaS product deployed across multiple customers.
| California office | 10880 Wilshire Boulevard, Suite 1101, Los Angeles, CA 90024 |
| Relevant work | EHR integration, healthcare interoperability, and custom application development |
| EHRs named in a selected project | Epic and Cerner |
| Integration methods | APIs, HL7, FHIR, and interface engines such as Mirth Connect, depending on the project |
| First scope to discuss | A defined data flow, its source fields, destination, and error-handling requirements |
| Homepage | osplabs.com |
Best fit: A healthcare product team that needs help with clinical data movement and system-specific interface work.
Worth discussing: Clarify which parts of the project involve product development, EHR interfaces, data mapping, and ongoing support.
Bitcot: Healthcare App Development and EHR Connectivity
Bitcot is a San Diego software development company that builds applications for healthcare and other industries. Its healthcare services include product development and integration with existing EHR systems.
The company may be worth considering if your team needs both application work and an EHR connection. For instance, you may be building a patient-facing product while also planning how it will receive appointment or clinical information from a provider’s system.
Bitcot’s healthcare development page names Epic, Oracle Health/Cerner, and athenahealth among the systems it works with. The company describes using FHIR R4 APIs, HL7 v2 messaging, and SMART on FHIR, with the approach depending on the workflow and customer environment.

| Relevant work | Healthcare application development and EHR integration |
| EHRs named in its services | Epic, Oracle Health/Cerner, and athenahealth |
| Integration methods | FHIR R4, HL7 v2, SMART on FHIR, and OAuth 2.0 |
| First scope to discuss | One application feature and the EHR data it needs |
| Homepage | bitcot.com |
Best fit: A healthcare SaaS company seeking application development and EHR integration within the same engagement.
Worth discussing: Ask for examples that align with your intended workflow and confirm how the team handles integration maintenance after the initial release.
What Does Your SaaS Product Need From Each EHR?
Before comparing technical approaches, define what users need to accomplish. “We need EHR integration” can describe several very different projects.
| Product need | Example | What to clarify |
|---|---|---|
| Read information | Retrieve patient demographics or appointment details | Which fields are available, who can access them, and how current the information needs to be |
| Send information to an EHR | Add an approved observation or document to a patient record | Whether the target system supports the required action and what permissions apply |
| Open within an EHR workflow | Let a clinician launch your application with patient context | Launch options, authentication, user roles, and the supported workflow |
| Receive events or messages | Receive updates when an appointment or admission changes | Message format, delivery expectations, duplicate handling, and recovery from failures |
| Exchange documents | Make a document available to an authorized user | Document format, access rules, source identification, and how updates are handled |
A scheduling application may need a narrow set of appointment and patient details. A care coordination product may need a broader view of clinical information and a way to send updates back. Those projects should not receive the same scope simply because both are described as EHR integrations.
If Epic and Oracle Health are among your target systems, our guide to Epic and Cerner integration offers additional background on the systems and integration approaches.
Why One EHR Connection May Still Need Customer-Specific Work
Two customers can use the same EHR vendor and still have different environments. Your team may need to account for separate endpoints, credentials, permissions, available data, and local workflows.
For example, Oracle Health’s documentation states that its FHIR service URLs vary by customer environment. That does not mean every part of an integration must be rebuilt, but it does mean the deployment process should account for customer-specific configuration.
Ask your development partner to show which elements will be shared across customers and which ones need to be configured or tested separately.
Should You Build Direct Connections or Use an Integration Platform?
A healthcare SaaS company can build connections directly to EHR systems, use an interoperability platform, or combine the two approaches. Each option deserves a conversation before your team commits to an architecture.
| Approach | Why a SaaS company might consider it | What to investigate |
|---|---|---|
| Direct EHR connections | Greater control over how a specific connection is built and maintained | Development effort, EHR-specific requirements, customer onboarding, and long-term support |
| Interoperability platform | Access to an existing platform and the interfaces it offers | Supported EHRs, data fields, actions, customer environments, fees, and contractual terms |
| Combination of both | Use a platform for some connections and custom work for particular workflows | How the approaches will work together and who will resolve issues across them |
For example, an interoperability platform may cover the information your product needs for several customers. But if a prospective customer requires a specialized workflow or a data element outside that platform’s available interfaces, your team may need additional work.
A direct connection also deserves a full cost discussion. The initial build is one part of the decision; testing, customer deployments, monitoring, and future changes need owners too.
How Can You Prepare for Multiple Customer Deployments?
A successful first connection gives your team an opportunity to make the next deployment easier to plan. The goal is to identify what worked, document the differences, and give your support team enough information to operate the integration.
Define the Data and Permissions
List the information your product needs for the selected workflow. Include where each field comes from, what it means in your product, and who is authorized to access it.
Also distinguish between information the product can read and actions it needs to perform. Access to an EHR API does not automatically mean every field or write action is available.
Plan Customer-Specific Configuration
Decide how your team will manage each customer’s endpoints, credentials, permissions, and testing environment. These details should be available to the people responsible for onboarding and support without requiring a developer to reconstruct the setup from old messages.
Where your product serves multiple organizations, discuss how customer data and integration credentials will be separated and controlled.
Test More Than the Successful Path
A demonstration may show that your product can retrieve a patient record. Your test plan should also cover the situations that need attention before users depend on the connection.
For example:
- What happens when a patient identifier does not match?
- What if a required field is missing or uses an unexpected value?
- How does the product handle a duplicate message?
- What happens when an EHR endpoint is unavailable?
- Can the team identify which customer and workflow were affected?
- Who reviews a failed transaction before it is retried?
If your product prepares EHR information for reporting or AI, the data also needs to retain the meaning and context required for that use. Our guide to healthcare data engineering partners explores work such as data preparation, mapping, and quality checks.
Agree on Support After Launch
An integration needs a plan for monitoring and maintenance. Discuss who receives alerts, who investigates failures, and how your team will coordinate with the customer or EHR vendor when a change affects the connection.
Your agreement should also address documentation, credential updates, testing after changes, and how a customer reports a problem.
What Should You Ask an EHR Integration Partner?
Bring a short description of your product and the workflow you want to support. You do not need every technical decision settled, but these questions can help you compare proposals:
- Which EHRs and workflows has your team worked with? Ask for examples that are relevant to the actions your product needs.
- What will the first connection include? Identify the data, users, permissions, environments, and tests included in the scope.
- What can be reused for later customers? Ask the team to distinguish shared components from customer-specific setup.
- How will you handle EHR and customer requirements? Discuss the applicable access process, testing, and production onboarding.
- How will you test failures? Request examples covering missing data, duplicate messages, unavailable systems, and incorrect patient matches.
- Who owns the code and configuration? Clarify access to documentation, integration components, and customer-specific settings.
- What happens after launch? Agree on monitoring, support responsibilities, and how changes will be assessed.
- Which costs sit outside the development proposal? Ask about any applicable platform subscriptions, third-party services, access fees, and ongoing support.
A useful proposal should give your team a clear first deliverable and explain the decisions that still depend on the EHR vendor or healthcare customer.
Plan Your First Multi-EHR Integration
If your product needs to connect to several EHRs, start with the customer workflow that matters most. Choose one customer and one system, define the information and permissions required, and agree on how the connection will be tested and supported.
Once that work is complete, review what can carry over to the next deployment. The answer will give you a more practical basis for planning the next EHR connection and the engineering work around it.
If you are planning a healthcare SaaS product or extending an existing one, discuss your EHR integration with TATEEDA. We can review your product, target systems, and the workflow you want to support first.
Frequently Asked Questions
Can One Healthcare SaaS Application Connect to Multiple EHRs?
Yes. A healthcare SaaS application can connect to multiple EHRs through direct integrations, an interoperability platform, or a combination of both. The available data, supported actions, access requirements, and customer setup depend on the systems and workflows involved.
Does FHIR Make Every EHR Integration the Same?
No. FHIR provides a common standard for exchanging healthcare information, but implementations and available capabilities can differ. Your team still needs to check the relevant resources, permissions, endpoints, and requirements for each connection.
Can a SaaS Product Write Information Back to an EHR?
Sometimes. A product may be able to submit information to an EHR if the relevant interface supports the action and the appropriate access is granted. Confirm the specific data, workflow, permissions, and testing requirements with the EHR vendor and healthcare customer.
How Much Does Healthcare SaaS EHR Integration Cost?
The cost depends on the number of EHRs, the data and actions required, the condition of the existing product, testing, customer-specific work, and ongoing support. External platform subscriptions or other third-party charges may also affect the budget. Ask each partner to separate the initial build, customer onboarding, and maintenance in its proposal.
Who Maintains an EHR Integration After Launch?
That depends on your agreement. Your internal team, the development partner, an interoperability platform provider, or a combination of these parties may be responsible for different parts of the connection. Establish who monitors it, investigates failures, manages credentials, and tests changes before the product goes live.
