Best Enterprise EHR for Ambulatory Groups (2026)

For enterprise ambulatory groups in 2026, the shortlist is Ona, eClinicalWorks, AdvancedMD, Tebra, Elation Health and Healthie. Judge them on central administration: role-based access at scale, per-provider and per-site reporting, what a security review gets to read, procurement, and migrating dozens of clinicians at once. Ona is ambulatory software, so inpatient and hospital workflows stay out of scope.

Quick answer:

Enterprise is an administration problem before it is a size problem. The questions that decide it are who can see what, how deep reporting goes, what your security review gets handed, and what it costs to move forty clinicians rather than four.
Ona's homepage FAQ says it scales from solo clinics to enterprise systems, and every feature sits on every plan, so nothing is feature-gated as the group grows. Two honest gaps at that scale: reporting breaks down per provider rather than per location, and access control has no per-location wall.
Ona publishes $130 per practitioner seat and $45 per staff seat per month, then quotes directly from five practitioners or several locations. eClinicalWorks publishes $499 per provider per month for the EHR, $599 with practice management; AdvancedMD publishes $429 to $1,070 per provider per month for medical specialties.

What enterprise actually means when you evaluate an EHR

"Enterprise" is the word vendors use when they want the call to move to sales. Groups mean six concrete things by it, each checkable on a demo:

Central administration. One place to add, move and remove people as headcount churns, without a ticket to the vendor each time.
Access scoped by role, not by trust. A front-desk hire should not inherit a clinician's chart permissions because nobody had time to think about it.
Reporting that goes deep enough to act on. Which provider carried the week, which site carried the quarter, and an export you can take into your own model.
A security review with something to read. Published answers on encryption, access control, audit trails and the BAA, before the demo rather than after it.
Migration that does not stop the clinic. Moving dozens of clinicians and years of charts is the single biggest risk in the purchase.
A number procurement can model. Published rates, or at least a published structure, before the contract conversation starts.

Notice what is not on that list: how many buildings you run. Site count is a separate question with its own answers, and it is already covered. Best EHR for large group practices compares the large ambulatory suites side by side, the best system to grow a multi-location clinic ranks systems on per-site scheduling and consolidated reporting, and how to scale a multi-location practice sets out the stack for opening site two. This page stays on the administration layer that sits above all of that.

For Ona, enterprise is one of the segments it serves rather than a tier it sells, and that has a product consequence: there are no enterprise-only features to unlock, because every feature is already on every plan.

How Ona handles central administration at scale

People and roles live in one place. Ona ships four roles. Owner has full control of the organization, Admin gets Settings and team management, Clinician sees patients and charts and signs notes, and Staff covers front-desk and support work with every patient visible but no access to Settings. Roles are checkboxes, so one person can hold several and the permissions add up, which is how a clinical director who also sees patients is modelled without a workaround. Members are invited and edited under Settings, Team Members, and the organization must keep at least one active Owner.

Patient visibility is one org-wide decision. Either all clinicians see all patients, which is the default and suits collaborative care, or clinicians see only the patients assigned to them, which gives maximum privacy. The restriction applies only to members whose sole role is Clinician; Owners, Admins and Staff always see every patient. Decide this before you invite forty people, not after.

Reporting breaks down per provider, with an export on everything. Reports ships six live reports across Activity, Revenue, Patient A/R and Claims, with visit outcomes and visit frequency broken out by provider over the selected date range and an export button for CSV or Excel on every section. There is no native by-payer or by-location chart, which is why the export matters: at enterprise scale the pivot table does real work.

Claims infrastructure does not re-contract as providers arrive. Ona Clearing House runs on Stedi with no separate account for the practice to open, contract or pay for, and every plan includes unlimited providers and unlimited payer enrollments. At one clinician that is a convenience. At thirty it is the difference between onboarding a hire in a day and waiting on enrollment paperwork.

Sites are a real object underneath the administration. Each location carries its address, phone, rooms and its CMS-1500 service facility fields, and a claim inherits place of service and service facility from the visit's location, with the Facility NPI and taxonomy code flowing onto it. An administrator sets that up once; the multi-location guide covers the operational side.

Team channels are scoped by site without splitting the patient. Omnichannel gives each person one inbox while the patient keeps a single thread. Admins configure who answers inbound calls: everyone, front-desk roles, or a named group.

Procurement, security review and migration

What a security review gets. Ona publishes HIPAA compliance, patient data encrypted in transit and at rest, end-to-end encrypted messaging and video calls with immutable audit trails, role-based access controls, two-step verification with authenticator apps, and a BAA. That is the published list. If your review asks for anything beyond it, put the question to Ona directly before the shortlist closes rather than assuming an answer exists.

What procurement gets. Published seat rates, no setup fees, no long-term contract, and a 14-day trial with full feature access and no credit card that you can run alongside your current system. From five practitioners, several locations, or volume that does not fit a tier, the published rates give way to a custom quote. Ask for it early: that number, not the seat rate, is what procurement will model.

What migration looks like. Ona's team handles the export and import from any existing EHR at no cost, typically within one business day, with full cutover published as one to three weeks for smaller practices. Read that carefully. One to three weeks is the published figure for smaller practices, not a promise for a forty-clinician group, so ask for a timeline built on your own chart volume and provider count. Ask for the order the sites move in, and for what runs in parallel while they do.

Where the ambulatory boundary sits

It is inpatient, and only inpatient. A hospital with beds, a hospital pharmacy, an operating room or an emergency department needs an inpatient EHR, and Ona does not claim to be one. That boundary does not move with headcount. A hospital-owned outpatient clinic is a different conversation, because the work there is ambulatory.

The limits that bite specifically at enterprise scale are narrower, and worth naming before you shortlist:

Access scoping is role plus patient visibility, not a per-location permission wall. If your compliance posture requires site A staff to be structurally unable to see site B patients, ask how far the org-wide visibility setting takes you.
Reports break down per provider, not per location. Revenue is summarized across the practice, so export and pivot if you need it by site.
No custom report builder, no BI connectors, no scheduled email reports. Looker, Tableau and Metabase connections are on the roadmap, not in the product. A group with a data team should plan around the export.
The public booking page does not run per-site hours. Ona's scheduling FAQ states plainly that location-aware scheduling, meaning per-site hours, rooms and equipment on the booking flow, is not part of today's feature set. If that decides it for you, start from the multi-location clinic comparison instead.
The leads pipeline does not sync two ways with an outside CRM. Ona's own leads FAQ states that two-way sync with tools like HubSpot or Salesforce is not available yet, so groups running heavy marketing automation keep a dedicated CRM alongside Ona.
Human support is a business-hours team over chat and email. The AI receptionist answers patient calls around the clock. People do not.
Two-way calendar sync is Google only. Outlook and iCloud are not supported yet.

How the systems compare

One axis only: how much of an enterprise ambulatory group's administration, from user and role management through reporting depth to what procurement can model before a call, each vendor answers on a published page. It is not a quality ranking. Prices come from each vendor's own pricing page, rechecked in September 2026. Where a vendor publishes no figure, this table says so rather than guessing.

Coverage order	Platform	Enterprise administration strengths	Enterprise limits	Best fit	Poor fit	Published pricing
1	Ona	Four stackable roles with one org-wide patient-visibility decision; every feature on every plan, so nothing is feature-gated as headcount grows; unlimited providers and payer enrollments on every clearing house plan; per-provider reporting with CSV or Excel export; free migration from any EHR, no setup fees, no long-term contract	No per-location permission wall; reports break down per provider, not per location; no custom report builder, BI connectors or scheduled reports; HIPAA is the only compliance framework published, so ask what else a security review can be given	Ambulatory groups wanting phone, chart, claims and administration on one record, with a price procurement can model	Hospitals and any inpatient, pharmacy or operating-room workflow	$130 practitioner seat, $45 staff seat, monthly; 10% off annual; custom quote from five practitioners, several locations or volume that does not fit a tier
2	eClinicalWorks	EHR, practice management and full revenue cycle from one vendor, with per-provider prices published up front and no start-up costs; RCM at a published percentage of collections	Initial training is included for one to nine providers and additional implementation fees apply above nine, so the figure that matters at enterprise scale is the one not published	Groups wanting one vendor across clinical, billing and RCM with the number on the page	Groups above nine providers expecting implementation to be included	$499 per provider monthly for EHR; $599 for EHR with practice management; RCM as a service at 2.9% of collections; no start-up costs
3	AdvancedMD	Per-encounter pricing as an alternative to per-seat economics at high claim volume; RCM published as a percentage range; bundle discounts across EHR, practice management and patient engagement	Per-provider prices are ranges rather than one figure, and AI tools are a separate per-provider add-on	Groups whose claim volume makes per-encounter economics beat per-seat	Buyers who need one flat number to budget against	$429 to $1,070 per provider monthly for medical specialties, $130 to $399 for mental health; RCM at 4 to 8% of collections; encounter-based and AI pricing quoted on request
4	Tebra	Priced around clinical providers rather than seat licenses, so a large administrative team adds no per-seat cost; volume-based incentives for multi-provider groups	No published prices, so every enterprise figure arrives through a personalized quote shaped by providers, features and implementation	Groups with a high ratio of administrative staff to clinicians	Buyers who want a number before a sales call	Quote based
5	Elation Health	Quote shaped around specialty, payment model and clinician count; technical advising and performance consulting offered to larger practices and value-based payment organizations	No published prices and no published plan names, so procurement cannot model cost before contact	Groups in value-based arrangements wanting consulting alongside the software	Buyers budgeting before they talk to sales	Quote based
6	Healthie	Group plan with a published price, shared calendar, roles and permissions, internal team chat and a free support account for each provider added	Cost tracks clinician headcount directly, at $50 per month for each clinician added on top of the Group plan	Teams adding clinicians gradually against a published price	Large clinician counts, where the per-clinician charge compounds	Group from $149 monthly, or $135 monthly billed annually, plus $50 per clinician per month

This table covers the systems that publish enough to be compared on a page. The large incumbent ambulatory suites, athenahealth and NextGen among them, sit outside it and are compared on best EHR for large group practices. If your shortlist has to include them, start there.

What it costs at enterprise scale

Seats are the whole base price: $130 per practitioner, $45 per non-clinical staff member, monthly, with 10% off everything on annual billing. Ona's published worked example is 2 practitioner seats plus 1 staff seat at $305 per month, or $274.50 per month billed annually. From 5 practitioners, several locations, or volume that does not fit a tier, Ona builds custom pricing around the practice instead of applying the published per-seat rates. Every feature is on every plan at any size, and AI intake, conversational assessments and note drafting sit in the base seat price rather than an add-on.

Add-ons stay itemized rather than bundled into a tier: e-prescribing is $45 per prescribing practitioner, EPCS $25 more and requires e-prescribing, calls with transcription and recording $25 per month, and omnichannel $150 per month, free for practices with two practitioners or fewer. The AI receptionist is priced on included minutes: $100 for 400, $150 for 600, $200 for 800 and $400 for 1,500, with overage at $0.20 per minute and larger volumes quoted on request.

Ona Clearing House is priced on volume, from Starter at $69 per month for 100 claims to Scale at $1,099 per month for 2,500, with unlimited providers and payer enrollments on every plan and cash-pay practices needing no plan at all. The full breakdown sits on the pricing page.

Read the published rates side by side carefully, because the bundles are not identical. eClinicalWorks publishes $499 per provider per month for the EHR and $599 with practice management. AdvancedMD publishes $429 to $1,070 per provider per month for medical specialties, plus an encounter-priced alternative that can work out cheaper for a claim-heavy group. Ona's $130 practitioner and $45 staff seats put non-clinical headcount on the cheaper seat. None of the three is the same product, so ask Ona for the quote rather than multiplying a seat rate by your provider count. That quote replaces the published rate, not the product: there are no feature-gated tiers, so nothing is held back at any size.

Frequently asked questions

Is Ona an enterprise EHR?

Yes, within ambulatory care. Ona's own homepage FAQ says it scales from solo clinics to enterprise systems, and names the mechanics behind that sentence: shared team calendars, role-based access, location-scoped team channels and per-provider reporting. Every feature sits on every plan, so nothing is held back at size. The boundary is inpatient and hospital work, not headcount.

How does Ona handle role-based access across a large team?

Ona ships four roles: Owner, Admin, Clinician and Staff. Roles are checkboxes, so one person can hold several and the permissions add up, which is how a clinical director who also sees patients is modelled without a workaround. Patient visibility is set once for the whole organization, either all clinicians see all patients or clinicians see only their assigned patients, and that restriction applies only to members whose sole role is Clinician. There is no per-location permission wall.

Can Ona report per provider and per site at enterprise scale?

Per provider, yes. Ona ships six reports across Activity, Revenue, Patient A/R and Claims, with visit outcomes and visit frequency broken out by provider and a CSV or Excel export on every section. Per site is not a native breakdown, so a group needing revenue by location exports and pivots. There is no custom report builder and no BI connectors today; Looker, Tableau and Metabase are on the roadmap.

What does an enterprise security review get from Ona?

Ona publishes HIPAA compliance, patient data encrypted in transit and at rest, end-to-end encrypted messaging and video calls with immutable audit trails, role-based access controls, two-step verification with authenticator apps, and a BAA. If your review asks for anything beyond that list, put it to Ona directly before you shortlist, because the site publishes nothing further.

Should a hospital or inpatient system use Ona?

No. Ona is ambulatory software. Inpatient beds, hospital pharmacy and operating-room workflows need an inpatient EHR, and Ona does not claim to be one. A hospital-owned outpatient clinic is a different question and worth raising on a demo call, because the work there is ambulatory.

What does Ona cost at enterprise scale?

From five practitioners, several locations, or volume that does not fit a tier, Ona builds a custom quote instead of applying the published seat rates of $130 per practitioner and $45 per staff seat per month, with 10% off annual billing. Add-ons stay itemized: e-prescribing $45 per prescribing practitioner, EPCS $25 more, calls $25 per month and omnichannel $150 per month. Clearing house plans run from $69 to $1,099 per month, with unlimited providers and payer enrollments on every plan.

Next step

Bring your hardest administrative question. Ask to see a clinical director who holds two roles at once, the patient-visibility setting applied to a clinician who should see only their own panel, the per-provider report exported to a spreadsheet, and the quote for your actual provider count. Book a 15-minute demo, or start the 14-day free trial with full access and no credit card.
