Should you use power automate for RPA? A practical guide
Microsoft Power Automate is a widely recognised robotic process automation (RPA) tool, but is it the right solution for your business?
For organisations working within the Microsoft ecosystem, Power Automate offers low-code automation to streamline repetitive tasks, particularly those involving Office 365, Teams and SharePoint. However, when businesses require enterprise-scale automation, cross-platform compatibility or advanced test automation, Power Automate may not be the best choice. Understanding when to use Power Automate – and when to look elsewhere – can prevent costly implementation failures.
At T-Plan, we specialise in advanced automation solutions that go beyond Power Automate’s capabilities. In this guide, we’ll examine where Power Automate works well, its limitations and when a more flexible RPA solution is required.

What is Power Automate?
Power Automate is Microsoft’s RPA and workflow automation platform, designed to simplify repetitive business processes. It allows users to automate tasks using pre-built connectors, cloud flows and UI-based automation.
Power Automate primarily serves businesses that:
- Operate within the Microsoft 365 ecosystem.
- Require basic process automation rather than complex, enterprise-grade RPA.
- Need a low-code solution for non-technical users.
Power Automate’s strengths
Power Automate has gained popularity due to its seamless integration with Microsoft products. Its key advantages include:
- Integration with Microsoft applications – Works effortlessly with Excel, Outlook, SharePoint and Dynamics 365.
- Low-code interface – Business users can create workflows with minimal technical expertise.
- Automation of everyday tasks – Ideal for data transfers, email notifications and approval workflows.
- Cloud-based automation – Supports both web-based and desktop processes via Power Automate Desktop.
While these features make Power Automate a good option for basic office automation, they also highlight its limitations. How well does it scale? Can it handle complex RPA needs? Let’s explore where Power Automate excels – and where it falls short.
When power automate works well
Power Automate is best suited for simple, rule-based automation that does not require significant customisation or scalability. Businesses that operate primarily in Microsoft 365 will find Power Automate useful for:
1.Basic office automation
Power Automate can effectively streamline repetitive, manual tasks, including:
- Copying and pasting data between Microsoft applications.
- Triggering automated email notifications based on business events.
- Generating reports and updating spreadsheets in Excel.
- Managing approval workflows for documents and invoices.
2. When your business runs on Microsoft ecosystem
For organisations heavily invested in Microsoft tools, Power Automate simplifies automation by providing:
- Pre-built connectors to integrate Microsoft applications with minimal configuration.
- Automation within Teams, Outlook and SharePoint without requiring custom development.
- Cloud-based execution that eliminates the need for local infrastructure.
3. Simple, rule-based workflows
Power Automate is effective for tasks that follow clear, predefined rules, such as:
- Scheduling email reminders and task notifications.
- Updating CRM records based on form submissions.
- Data synchronisation across Microsoft applications.
However, as businesses scale up their automation needs or require cross-platform compatibility, Power Automate’s limitations become apparent. Where does it struggle?
When Power Automate falls short
Despite its strengths, Power Automate has notable weaknesses that limit its suitability for complex automation.
If you need cross-platform automation
Power Automate is primarily Windows-based and lacks robust support for macOS, Linux or hybrid operating system environments. Businesses using a diverse technology stack may find it restrictive.
Additionally, while Power Automate provides API-based integration, it struggles with applications that lack modern connectors. This can create challenges for companies that use software outside the Microsoft ecosystem.
For legacy and back-office systems
Many older CRM, ERP and billing systems do not have APIs, making them difficult to automate using Power Automate. While UI-based automation is possible, it is often unreliable for outdated software, particularly when dealing with dynamic user interfaces.
T-Plan, by contrast, offers advanced UI-based automation that ensures compatibility with legacy applications, even when no APIs are available.
If scalability is a concern
Power Automate is not designed for high-volume, enterprise-wide automation. As workloads increase, businesses may experience:
- Performance bottlenecks when automating thousands of tasks simultaneously.
- Challenges in scaling RPA bots efficiently compared to dedicated automation platforms.
T-Plan’s enterprise-grade scalability ensures that automation processes remain efficient, even as demand increases.
For advanced test automation
Power Automate lacks dedicated testing capabilities, meaning:
- There is no built-in verification for automated workflows.
- Errors in automation may go undetected, leading to process failures.
- Businesses may experience unexpected automation breakdowns without clear diagnostic tools.
For organisations that require robust testing, T-Plan provides specialised RPA testing tools that validate automated workflows, ensuring reliability and accuracy.
Choosing the right RPA tool for your needs
While Power Automate serves well in specific use cases, businesses with more complex automation needs often find its limitations restrictive. If your organisation requires scalability, cross-platform compatibility or robust testing, it’s essential to explore alternative RPA solutions that can provide greater flexibility and efficiency.
Let’s compare Power Automate with other RPA solutions to determine which is the best fit for your business.
Power Automate vs. other RPA solutions
