Choosing between building a custom solution using Microsoft Power Platform or purchasing an off-the-shelf (OTS) software solution is a major decision for businesses. While OTS solutions offer quick deployment and standard functionalities, Power Platform provides flexibility and customization tailored to unique business needs.
In this post, we’ll explore a decision framework to help you determine when to build with Power Platform versus when to buy a pre-built solution. We’ll also discuss practical examples to illustrate these choices in real-world scenarios.
Understanding the Build vs Buy Decision
Before diving into the specifics, it’s important to weigh several key factors that influence the decision to build or buy:

- Customization Needs – Does your business require highly specific workflows and automation?
- Time to Deployment – Do you need a solution urgently, or can you afford a phased rollout?
- Cost Considerations – What is the total cost of ownership over time?
- Scalability & Future Growth – Will the solution grow with your business needs?
- Integration Requirements – How well does the solution work with your existing tools and systems?
- Security & Compliance – Are there industry-specific regulations to consider?
When to Build with Power Platform
Power Platform (Power Apps, Power Automate, Power BI, and Power Virtual Agents) is ideal when:
- You Need High Customization: If your business processes are unique and cannot be fulfilled by standard OTS software, Power Apps allows for tailored application development.
- Agility & Rapid Development Are Key: Power Platform enables citizen developers and IT teams to prototype, test, and deploy solutions rapidly.
- You Want Seamless Integration: Microsoft 365, Dynamics 365, Azure, and third-party systems integrate easily with Power Platform, ensuring data consistency.
- Cost Optimization is a Priority: Instead of licensing multiple OTS solutions, businesses can build only what they need, reducing unnecessary expenses.
- Automation is Crucial: Power Automate streamlines manual processes, improving efficiency and reducing human errors.
When to Choose Off-the-Shelf Solutions?
OTS solutions are a better fit when:
- The Need is Urgent: If a solution exists that meets 80-90% of your needs and can be deployed quickly, buying is often the best option.
- Industry-Specific Compliance is Required: Certain industries, such as healthcare and finance, necessitate certified solutions to comply with stringent regulations.
- Support and Maintenance Are a Concern: Vendors handle updates, security patches, and troubleshooting, reducing the internal maintenance burden.
- You Need Proven, Scalable Solutions: Large-scale, widely adopted software often provides robust features that have been tested extensively.
Build vs. Buy: A Quick Decision Framework
Use this structured approach to evaluate whether building with Power Platform or buying an OTS solution is the best choice:

Real-World Examples
Example 1: Automating Expense Approvals
A mid-sized company needs a solution to streamline its expense approval process. Instead of purchasing a standalone expense management software, they build a Power Apps solution integrated with Power Automate. The app allows employees to submit expenses, managers to approve them via Teams, and finance to process payments efficiently.
Why Power Platform Wins: High customization, cost savings, and seamless integration.
Example 2: Implementing a CRM System
A sales team requires a CRM solution to track leads, manage accounts, and generate reports. Dynamics 365 or Salesforce provides comprehensive features out-of-the-box, saving months of development time.
Why Off-the-Shelf Wins: Faster deployment, proven scalability, and vendor support.
Example 3: Managing IT Service Requests
An IT department needs a simple service request tool that integrates with Microsoft Teams and SharePoint. Instead of buying an ITSM tool, they use Power Apps and Power Automate to create a request tracking system.
Why Power Platform Wins: Cost-effectiveness, deep Microsoft 365 integration, and flexibility.
Example 4: Compliance and Regulatory Reporting
A financial institution requires software that meets industry regulations. Since off-the-shelf compliance software comes with built-in audit trails and legal reporting, it makes more sense to purchase rather than build.
Why Off-the-Shelf Wins: Regulatory compliance, reduced legal risk, and vendor support.
The Bottom Line
Choosing between build vs buy isn’t always a straightforward decision. It depends on your business needs, budget, scalability requirements, and how much customization you require.
Power Platform is a game-changer for businesses needing tailored, agile, and cost-effective solutions, while off-the-shelf software provides speed, compliance, and vendor support.
By using this decision framework, you can confidently choose the right approach, ensuring maximum value and efficiency in their technology investments.
