Power Apps vs Power Automate vs Power BI: which tool for which job

Apps people use, flows that run, reports people read. Real jobs matched to each tool, how the three work together, and what each licence costs.

Power Apps, Power Automate and Power BI aren't rivals; each does a different job. Power Apps builds the apps people use to enter and change data. Power Automate runs the work nobody should do by hand, on a trigger, a schedule or a button. Power BI turns data into reports people read and explore. Pick by asking what the person needs to do, and expect most real solutions to use more than one.

Note

Checked against Microsoft Learn on 22 October 2026, and against Microsoft's pricing pages.

Start from the job: an app, a flow or a report, and usually more than one.

The three at a glance

	Power Apps	Power Automate	Power BI
You build	Apps	Flows	Reports and dashboards
People	Use it to enter, find and change data	Rarely see it: it runs on a trigger, a schedule or a button	Read it, filter it and drill into it
Built in	Power Apps Studio (canvas) or the app designer (model-driven)	The Power Automate designer	Power BI Desktop, then published to the Power BI service
Runs in	A browser, the Power Apps mobile app, Teams	Microsoft's cloud (cloud flows) or a Windows machine (desktop flows)	The Power BI service and the Power BI mobile apps
Writes data?	Yes, that's its main job	Yes, as steps in a flow	Mostly reads; write-back is newer and narrower (see below)
Data	Connectors or Dataverse	Connectors or Dataverse	More than 100 sources in Power BI Desktop, shaped with Power Query

All three can work on the same Dataverse tables and use the same family of connectors, which is why they combine so easily.

What each tool is for

Power Apps: apps people use

Choose Power Apps when a person needs a screen: to fill in a form, tick through a checklist, look up a record or update a status. A canvas app gives you a blank screen and Excel-like Power Fx formulas; a model-driven app builds its screens from Dataverse tables. What is Power Apps explains the app types, and canvas vs model-driven helps you pick between them.

Power Automate: work that runs by itself

Choose Power Automate when the work should happen without someone driving it: when an email arrives, every Monday at 8:00, or when someone presses a button. Microsoft lists three kinds of flow:

Cloud flows, started automatically by an event, instantly by a person, or on a schedule.
Desktop flows, Microsoft's robotic process automation (RPA), which automate tasks on the web or the desktop by working through an application's screens, useful for older systems that have no API.
Generative actions (preview), where you state the intent and AI chooses the steps.

A flow has no screen of its own. If people need to type something in, they do it in an app, a form, Teams or an email, and the flow picks it up. For heavy integration owned by IT, compare cloud flows with Azure Logic Apps.

Power BI: reports people read

Choose Power BI when people need to understand data: totals, trends, comparisons and drill-down across thousands or millions of rows. You build reports in Power BI Desktop (a free download), where you model the data with relationships and DAX, then publish to the Power BI service to share them and schedule refreshes.

Power BI is for reading, not data entry. Microsoft has added a way to write back from a report, translytical task flows, which call Fabric user data functions to add, change or delete rows in Fabric SQL databases, warehouses and lakehouse files. Microsoft announced it as generally available in the March 2026 Power BI Desktop update, though some Learn pages still label it a preview. It needs Fabric; Power BI write-back covers it. For general data entry on other sources, an app is still the tool.

Which tool for which job

The job	Tool	Why
Log a site inspection on a phone, with photos	Power Apps	A person fills in a screen
Book out laptops and track who has which	Power Apps	Lookup plus update
Email the manager when a request is submitted, and record the approval	Power Automate	Triggered by an event, no screen needed
Copy new rows from one system to another every night	Power Automate	Scheduled, nobody watching
Click through an old desktop system that has no API	Power Automate (desktop flow)	Desktop flows automate screens
Show sales by region and month, with drill-down	Power BI	Reading and slicing lots of data
Track a KPI against a target across the year	Power BI	Totals and trends
Let a manager approve a budget line they've spotted in a report	Power BI + Power Apps	The app sits inside the report
Submit a request, route it for approval and report on cycle times	All three	App to submit, flow to route, report to measure

Name the person and the verb first: "the inspector records", "the system sends", "the director reviews". The verb picks the tool.
Keep each tool on its own job: logic that moves data belongs in the flow, not hidden in the app's button.

Don't

Don't build a "report" in Power Apps with galleries and charts when people only need to read totals; Power BI does that better.
Don't build a flow that emails a spreadsheet every morning when a shared report would do.
Don't expect a flow to give people a screen to fill in.

How they work together

A flow started from an app

The most common pairing. In Power Apps Studio, select Power Automate on the app authoring menu, then Create new flow, or Add a flow to reuse one that has a Power Apps trigger. Then call it from a button's OnSelect, passing any inputs the flow asks for:

powerfx

SendRequestEmail.Run(txtTitle.Text, User().Email)

A Power Apps per-user licence covers running a flow only when it's started through the Power Apps trigger like this, so a Power Apps Premium user doesn't need a separate Power Automate licence for it. Microsoft warns that the values an app passes to a flow are visible in network traffic, so the flow should check them before acting, for example confirming that an email address belongs to your organisation.

A Power Apps visual inside a Power BI report

Add the Power Apps visual to a report, choose the fields to pass, and create or pick a canvas app. The report's current filter context flows into the app as PowerBIIntegration.Data, so a manager can act on exactly the rows they're looking at. Limits worth knowing:

At most 1,000 records pass from the report to the app.
The visual can't filter the report or send data back to it.
You share the app separately from the report.
It works for embedding for your organisation, not for embedding for your customers.

A Power Automate button inside a Power BI report

The Power Automate visual (in Power BI Desktop, Insert > Power Automate) puts a button on the report that runs a flow with the reader's current selection, up to 1,000 records. Create the flow from inside the report, not in Power Automate, and give readers permission to run it. It doesn't work with Publish to web or embedded analytics.

Power BI inside an app, and alerts that start a flow

In a canvas app, Insert > Charts > Power BI tile shows a tile from a Power BI dashboard. Share the dashboard with the app's users too; Microsoft recommends no more than three tiles loaded at once.
A Power BI data alert can start a flow, through the When a data driven alert is triggered trigger, for example to email a team when a figure crosses a threshold.

Licensing in one minute

Each tool is licensed on its own. Microsoft 365 covers the basics of the first two; Power BI needs Pro to share. US list prices, per user per month paid yearly, in October 2026:

	Included with Microsoft 365	Paid options	Full guide
Power Apps	Apps that use standard connectors	Power Apps Premium $20 ($22 for terms from 1 January 2027), or $10 per active user per app on the pay-as-you-go meter	Power Apps licensing
Power Automate	Cloud flows that use standard connectors	Power Automate Premium $15; Process $150 per bot or flow	Power Automate licensing
Power BI	Building in your own My workspace with a free account; Pro comes with Microsoft 365 E5 and Office 365 E5	Pro $14; Premium Per User $24; viewers can stay free on an F64 or larger Fabric capacity	Power BI licensing

Premium connectors such as SQL Server, and Dataverse itself, push both Power Apps and Power Automate into their paid tiers. For the whole picture across products, see the Power Platform licensing map.
