Power Automate: what it is, how it works, and use cases in SMEs
You already use Microsoft 365 every day: Outlook, Teams, SharePoint, Excel. But did you know that your subscription includes an automation tool that can save you hours of repetitive tasks every week? That tool is Microsoft Power Automate.
Power Automate lets you create automated workflows between your applications without writing a single line of code. Send an email when a file arrives on SharePoint, create a Teams task when a form is filled out, automatically archive attachments in OneDrive: all this can be configured in just a few clicks.
In this guide, we explain in concrete terms what Power Automate is, how it works, what are the most profitable use cases for an SME, and how much it costs.
What exactly is Power Automate?
Microsoft Power Automate (formerly Microsoft Flow) is a low-code/no-code automation platform integrated into the Microsoft 365 ecosystem. It is part of the Power Platform, alongside Power Apps (application creation), Power BI (data analysis), and Copilot Studio (conversational agents).
The principle is simple: you define a trigger ("when X happens") and actions ("then do Y"). For example: "When I receive an email with an attachment from my supplier, save the attachment in SharePoint and notify the accounting team on Teams."
Power Automate offers two complementary operating modes:
- Cloud flows: automations between cloud applications (Outlook, SharePoint, Teams, Salesforce, SAP, etc.) via more than 1,000 preconfigured connectors.
- Desktop flows (Power Automate Desktop): automate tasks on your Windows computer—clicks, keystrokes, copy and paste in applications that don't have an API. It's RPA (Robotic Process Automation) natively integrated into Windows.
How does Power Automate work? The 3 types of flows
1. Automated flows (automatic trigger)
The flow starts automatically when an event occurs. Examples: receiving an email, creating a file in SharePoint, adding a new line to a list, modifying a CRM record. This is the most commonly used type of flow in businesses.
2. Instantaneous flows (manual triggering)
You can launch the flow yourself with a single click, from Teams, a button on your mobile device, or a Power Apps form. Ideal for on-demand processes: leave requests, quote approvals, incident reports.
3. Scheduled flows (recurrence)
The flow runs at regular intervals: every hour, every Monday morning, on the first day of each month. Perfect for automated reporting, data synchronization between systems, or automatic reminders.
7 concrete Power Automate use cases for SMEs
1. Approval of requests (vacation, purchases, quotes)
An employee fills out a form (Forms or Power Apps). The flow automatically sends the request to the relevant manager via Teams or email, waits for their response, then notifies the requester and updates the SharePoint tracking table. Result: no more lost emails, complete traceability, and validation time reduced by a factor of 3.
2. Automatic processing of emails and attachments
Do supplier invoices arrive by email? Power Automate detects them, extracts the attachments, saves them to the correct SharePoint folder, and creates a row in your Excel or Dataverse tracking table. No more manual sorting.
3. CRM ↔ Microsoft 365 synchronization
Created a new contact in your CRM (Dynamics 365, Salesforce, HubSpot)? Power Automate automatically syncs the information with your Outlook contact lists, SharePoint, or billing tool.
4. Automated employee onboarding
When a new employee is added to the HRIS or SharePoint list, the workflow automatically triggers: creation of the Teams profile, sending of the welcome kit by email, creation of SharePoint access, notification to the manager and IT.
5. Smart alerts and notifications
Receive a Teams notification when a customer responds to a form, when a document is modified, when a stock threshold is reached in your ERP, or when a support ticket is overdue. No more manual checks.
6. Automatic document generation
Power Automate can generate Word or PDF documents from templates: pre-filled contracts, customized quotes, meeting minutes. Data is automatically imported from your SharePoint lists or your CRM.
7. Legacy software automation (Power Automate Desktop)
Does your ERP or business software lack an API? Power Automate Desktop simulates human actions: opening applications, entering data, extracting reports, copying and pasting between systems. It's native Windows RPA, with no additional tools required.
How much does Power Automate cost? 2026 pricing
Good news: if you already have Microsoft 365 (E3 or E5), you have access to Power Automate with standard connectors, free of charge. Here are the license details:
Key point for SMEs: with a Microsoft 365 E3 subscription, your employees can already create cloud flows with standard connectors (Outlook, SharePoint, Teams, Excel, OneDrive, Forms). This is often enough to get started and achieve quick wins without additional investment.
Premium connectors (Salesforce, SAP, Dataverse, SQL Server, ServiceNow) require the Premium license at $15.99/user/month. This is usually the tipping point when your automations become more ambitious.
How to get started with Power Automate in SMEs?
Step 1 — Identify your 3 most repetitive tasks
Which processes take up the most time each week? Validating documents? Sorting emails? Entering data between two tools? These are your first candidates.
Step 2 — Start with a simple flow using Microsoft templates
Power Automate offers hundreds of ready-to-use templates: "Save Outlook attachments to OneDrive," "Notify Teams when a form is completed," "Copy Forms responses to Excel." Set up your first flow in 10 minutes.
Step 3 — Test, measure, iterate
Run the flow in real conditions for a week. Measure the time saved. Adjust the conditions and actions. Then move on to the next flow.
Step 4 — Seek assistance for complex scenarios
When your needs exceed standard connectors (ERP integration, RPA on business software, multi-step workflows with complex conditions), expert support speeds up deployment and avoids common pitfalls.
The limitations of Power Automate you should be aware of
- Premium paid connectors: Access to SAP, Salesforce, SQL Server, or Dataverse requires a Premium license ($15.99/user/month). The transition from the included plan to the paid plan may come as a surprise.
- Execution limits: 6,000 executions/day on the included M365 plan, 40,000 on Premium. For very high volumes, proper sizing is required.
- Learning curve for complex flows: simple flows can be created in 10 minutes, but multi-branch workflows with error handling and loops require real expertise.
- Dependence on the Microsoft ecosystem: if your IT system is primarily Google Workspace or non-Microsoft tools, Make, n8n, or Save Time Factory will be more suitable.
FAQ — Power Automate
Is Power Automate really free?
Partially. If you have Microsoft 365 E3 or E5, you can create cloud flows with standard connectors at no additional cost. Premium connectors, unattended RPA, and advanced features (AI Builder, Process Mining) require a paid license starting at $15.99/user/month.
Do you need to know how to code to use Power Automate?
Not for simple flows—the interface is visual, drag-and-drop, with ready-to-use templates. For complex flows (loops, nested conditions, API calls), some logic and training are recommended. IT Systems offers training tailored to your level.
Can Power Automate automate software without an API?
Yes, thanks to Power Automate Desktop (RPA). It simulates human actions on your Windows workstation: opening applications, data entry, data extraction, navigating interfaces. It is the ideal solution for automating legacy business software or ERPs that do not expose APIs.
At IT Systèmes, we complement this approach with FlexFlow, our iPaaS platform that natively integrates an RPA layer, while centralizing your data flows in a single solution.
What is the difference between Power Automate Cloud and Desktop?
Power Automate Cloud automates flows between cloud applications (emails, files, CRM) via connectors. Power Automate Desktop automates tasks on your Windows workstation by simulating clicks and keystrokes. The two can be combined: a cloud flow can trigger a desktop flow, and vice versa.
