What is Power Automate?
Power Automate is a Microsoft cloud service for building automated workflows, called flows, that connect apps and services such as Outlook, SharePoint, Excel, and hundreds of third-party connectors. A flow starts with a trigger, such as a new email arriving or a scheduled time, and then runs a series of actions, such as saving an attachment or sending a notification. It is part of the Microsoft Power Platform and requires no traditional coding, making it accessible to business users as well as developers.
Power Automate is Microsoft's automation platform for building workflows that connect apps, move data, and trigger actions without writing code.
What Power Automate does
Power Automate lets you build automated workflows, called flows, that react to events and carry out a sequence of actions without manual intervention. A typical flow might watch a SharePoint folder for new files, extract data from each one, and post a summary to a Teams channel, all without anyone touching the process after it is set up. It is part of Microsoft’s Power Platform, alongside Power Apps and Power BI, and is designed so business users without a programming background can build meaningful automation using a visual, drag-and-drop interface.
Flows are built from two core building blocks: a trigger that starts the flow, and one or more actions that run afterward. A trigger could be a new email arriving in a shared mailbox, a row being added to an Excel table, or simply a scheduled time each day. Actions carry out the actual work: sending an email, updating a record, calling an external API, or creating an approval request. Read more about how these two pieces differ in trigger versus action in Power Automate.
Types of flows
Power Automate supports several flow types depending on how they start. Automated cloud flows trigger from an event, such as a new file appearing in OneDrive. Scheduled cloud flows run on a fixed timetable, useful for daily reports or weekly cleanups. Instant cloud flows are triggered manually, often from a button in the Power Automate mobile app or embedded in Teams. Business process flows guide people through a structured, multi-step process such as an onboarding checklist. Choosing the right flow type depends entirely on what should set the automation in motion.
Common use cases
Organizations typically start with straightforward automations: routing approval requests, saving email attachments to SharePoint automatically, sending reminders for overdue tasks, or syncing data between two systems that do not natively talk to each other. A frequently requested scenario is automating invoice processing, where incoming invoices are extracted, validated, and routed for approval without manual data entry. As confidence grows, flows tend to expand into more business-critical processes, sometimes combined with AI Builder for tasks like extracting structured data from scanned documents.
Licensing and connectors
Power Automate is included at a basic level with many Microsoft 365 subscriptions, covering standard connectors such as Outlook, SharePoint, and Excel. Premium connectors, which include database connections, HTTP requests, and many third-party services, require an additional Power Automate licence, either assigned per user or per flow. Organizations planning to build flows that reach beyond Microsoft 365, into systems like Salesforce or custom APIs, should check licensing requirements early, since premium connector usage is a common surprise cost.
Where Power Automate fits alongside other tools
Power Automate sits comfortably in a Microsoft-centric environment, since it shares authentication, data connectors, and governance with the rest of Microsoft 365. Teams using a broader mix of tools sometimes compare it against alternatives such as n8n, which trades tight Microsoft integration for open-source flexibility and self-hosting options. Neither is universally better; the right choice depends on existing infrastructure, budget, and how much control over data and hosting matters to the organization.
Our tip: Start with one small, well-defined process, such as a single approval flow or notification, before expanding Power Automate into more complex, multi-step business logic. Early wins build the confidence and internal skill needed for larger automation projects.
Frequently asked questions
Is Power Automate free to use?
Power Automate has a free tier included with many Microsoft 365 business licences, which covers a limited set of connectors and run allowances, sufficient for simple internal flows. More advanced scenarios, such as using premium connectors (databases, HTTP requests, custom APIs) or higher run volumes, require a separate Power Automate licence, either per user or per flow. Organizations already paying for Microsoft 365 should check their existing entitlements before purchasing additional licences.
What is the difference between Power Automate and Power Apps?
Power Automate builds automated workflows that run in the background, triggered by events like a new file or a schedule, without requiring a user interface. Power Apps builds interactive applications with screens, forms, and buttons that people actively use. The two are often combined: a Power App might collect input from a user, which then triggers a Power Automate flow to process that data further, such as routing it for approval or updating a database.
Can Power Automate connect to non-Microsoft applications?
Yes. Power Automate includes hundreds of connectors beyond the Microsoft ecosystem, covering tools such as Salesforce, Slack, Dropbox, Google services, Twitter, and many industry-specific systems. If no pre-built connector exists for a given service, Power Automate can still connect through a generic HTTP action, as long as the target system exposes an API. This makes it usable even in organizations that run a mixed technology stack rather than a pure Microsoft 365 environment.
How does Power Automate compare to n8n?
Power Automate is a Microsoft-hosted, closed-source platform tightly integrated with Microsoft 365 and the wider Power Platform, billed per user or per flow. n8n is an open-source automation tool that can be self-hosted, giving more control over data location and cost at scale, with a steeper setup requirement. Organizations already invested in Microsoft 365 often find Power Automate the path of least resistance, while teams wanting more flexibility or lower long-term cost sometimes evaluate n8n as an alternative.
