For most practices on athenaOne, either tool will do the job, and the deciding factors are who builds the reports, what computers they use, and what you already pay Microsoft for. Power BI is usually cheaper per person, especially if your staff already have Microsoft 365 E5. Tableau costs more per author but runs natively on a Mac and suits a team where a few people do most of the analysis. Both read athenaOne Data View through Snowflake, and both vendors will sign a Business Associate Agreement (BAA) for their cloud service.
Our bias, stated plainly
Ben Miller, who leads EMBERSTONE Partners, built a v1 ambulatory quality measure engine and its Tableau reporting layer, then scaled it with engineering, operations and clinical teams to HEDIS, MIPS and clinician-level reporting for 2M+ primary care patients across about 2,600 sites of care in 19 states. So we know Tableau well. We also build Power BI views for practices that run on Microsoft, and we have no reseller relationship with either vendor. Every price and feature below links to the vendor's own page so you can check it.
What does each cost per user?
We checked list prices on November 5, 2026. Both vendors price per named user per month on yearly terms, and both say prices change, so treat these as a starting point for a quote.
| License | What the person can do | List price per user per month |
|---|---|---|
| Power BI free account | Build reports for their own use only | $0 |
| Power BI Pro | Publish and share reports | $14 (paid yearly) |
| Power BI Premium Per User | Pro plus larger models and more frequent refreshes | $24 (paid yearly) |
| Tableau Creator | Connect to data, build and publish | $75 (billed annually) |
| Tableau Explorer | Explore and edit published content | $42 (billed annually) |
| Tableau Viewer | View and interact with published dashboards | $15 (billed annually) |
Sources: Microsoft Power BI pricing and Salesforce Tableau pricing.
Two licensing details change the math. Microsoft says the free account must upgrade to Pro or Premium to share reports, and that Pro is already included in Microsoft 365 E5. Microsoft's license guide adds that, on shared capacity, only Pro users can view other Pro users' content; free users can view shared content only when it sits in Premium or Fabric F64 or larger capacity, which is priced separately. On the Tableau side, Viewers cannot connect to data or publish, so you need at least one Creator.
A worked example at list price: two report builders and 25 staff who only view dashboards. In Power BI that is 27 Pro licenses, or $378 a month, and $0 extra if everyone already has E5. In Tableau it is two Creators and 25 Viewers, or $525 a month. Your real numbers depend on your Microsoft agreement and any Salesforce discount.
How does each connect to athenaOne Data View?
athenahealth says Snowflake is at the core of Data View, with almost 400 tables, and that you can connect a business intelligence tool or warehouse to it with standard connectors such as ODBC and JDBC. That means both tools connect the same way they would to any Snowflake account. Our guide to pulling Data View into Snowflake covers the warehouse side.
- Power BI has a Snowflake connector that signs in with Basic, KeyPair or OAuth2 (Microsoft Entra ID) credentials. Single sign-on needs a Fabric administrator to turn on a tenant setting.
- Tableau connects through Snowflake's driver and supports OAuth, key-pair and several other methods. Tableau's help notes that Snowflake retired single-factor username and password sign-in as of May 2025, so plan for key-pair or OAuth from the start.
Before you choose, ask your athenahealth contact which sign-in methods your Data View account allows. That answer can rule a setup in or out faster than any feature list.
What about HIPAA?
Neither tool makes you compliant by itself. What you need is a signed BAA that names the service you use, plus sensible access controls.
- Microsoft says its HIPAA BAA comes by default through the Online Services Data Protection Addendum for covered entities and business associates, and lists the Power BI cloud service as in scope.
- Salesforce lists Tableau Cloud and Tableau Next as HIPAA covered services and states that Tableau Bridge, Tableau Data Connect and Tableau Server are not covered by its BAA. The same page asks customers to enable data masking in the Einstein Trust Layer where they control it.
In practice, that means Tableau Cloud rather than self-hosted Tableau Server if you want the vendor's BAA, and a check of any AI features you plan to switch on in either tool. Keep patient-level detail out of any report that does not need it.
Can each clinic or provider see only their own data?
Yes, in both tools. This is called row-level security, and it is what lets one dashboard serve every clinic manager without showing them each other's patients.
In Power BI you define roles with DAX filter expressions. Dynamic security uses USERPRINCIPALNAME() against a user-mapping table, so one role filters differently for each person. One catch: row-level security only applies to people with the Viewer role in a workspace. Admins, Members and Contributors see everything.
In Tableau you can map users by hand, which Tableau calls convenient but high maintenance, or use a security field driven by an entitlement table, which it describes as more secure. You can also filter a published data source so every workbook built on it inherits the restriction.
Either way, the pattern is the same: keep one table in the warehouse that maps each user to the clinics and providers they may see, and point the tool at it.
What skills does a small team need?
Both tools need someone who can write SQL against Data View and keep metric definitions consistent. Beyond that:
- Power BI authors build in Power BI Desktop, which Microsoft supports on Windows 10 or later, and write security rules and measures in DAX.
- Tableau authors with a Creator license build in Tableau Desktop, which installs on Windows or Mac, or in the browser, and write calculated fields, including the ones that drive row-level security.
The bigger risk is the same in both: three people defining "no-show rate" three ways. Write the definitions down once, in the warehouse, before anyone builds a dashboard. Our KPI scorecard guide has a starting list.
Decision table
| If this describes your practice | Lean toward |
|---|---|
| Staff already have Microsoft 365 E5 | Power BI |
| Many viewers, one or two builders, tight budget | Power BI |
| Report builders use Macs | Tableau |
| Your analyst already knows one tool well | That tool |
| You want the vendor BAA but need to self-host | Neither fits cleanly: Tableau Server is outside Salesforce's BAA, so talk to your compliance lead |
| You need clinic and provider views from one dashboard | Either, with a warehouse mapping table |
Where to start
List who will build reports, who will only view them, and what computers they use. Then price both tools for those exact counts and ask your athenahealth contact how your Data View account authenticates.
