Cost Comparison: Power Platform vs Custom Development
Power Platform Costs:
- Licensing (per user/month): £8-£40
- Development costs: £5,000 - £25,000
- Training and change management: £2,000 - £5,000
- Ongoing maintenance: £1,000 - £3,000/year
- Total Year 1: £15,000 - £45,000
Custom Development Costs:
- Development team (3-6 months): £50,000 - £150,000
- Infrastructure and hosting: £5,000 - £15,000
- Testing and quality assurance: £10,000 - £25,000
- Ongoing maintenance: £15,000 - £40,000/year
- Total Year 1: £80,000 - £230,000
UK Business Example: A mid-size manufacturing company needed a customer portal. Power Platform solution cost £18,000 and was delivered in 6 weeks. A custom development approach would have cost £120,000 and taken 4 months. The Power Platform solution delivered 85% cost savings and 75% faster time-to-market.
Timeline Comparison: Speed to Market
Power Platform Development Timeline
- Week 1-2: Requirements gathering and design
- Week 3-4: Development and configuration
- Week 5-6: Testing and user acceptance
- Week 7-8: Deployment and training
Custom Development Timeline
- Month 1-2: Requirements, architecture, and design
- Month 3-4: Development and coding
- Month 5-6: Testing, debugging, and optimization
- Month 7-8: Deployment, training, and support
When to Choose Power Platform
Power Platform is best for:
- Rapid prototyping and proof-of-concept development
- Business process automation and workflow management
- Data collection and reporting applications
- Integration with Microsoft 365 and Azure services
- Solutions requiring frequent updates and modifications
- Organisations with limited technical resources
UK Business Example: A UK retail chain needed to digitise their inventory management process across 50+ stores. Using Power Platform, they built a comprehensive solution in 4 weeks for £12,000. The same functionality would have required 6 months and £80,000+ in custom development.
When to Choose Custom Development
Custom development is best for:
- Complex algorithms and specialised business logic
- Unique user interface requirements
- Integration with legacy systems not supported by Power Platform
- High-performance applications with specific technical requirements
- Long-term strategic applications with extensive customisation needs
- Applications requiring complete control over architecture and deployment
Hybrid Approach: Best of Both Worlds
Many UK businesses find success with a hybrid approach:
Power Platform Components:
- Standard business processes and workflows
- Data collection and reporting
- User interface and forms
- Integration with Microsoft services
Custom Development Components:
- Complex business logic and algorithms
- Specialised integrations
- Performance-critical components
- Unique user experience requirements
Decision Framework
- What is your budget and timeline? Power Platform for faster, cheaper solutions; custom development for larger budgets and longer timelines.
- How complex are your requirements? Simple to moderate complexity favours Power Platform; high complexity may require custom development.
- Do you need extensive customisation? Limited customisation needs favour Power Platform; extensive customisation may require custom development.
- What are your technical resources? Limited technical resources favour Power Platform; extensive technical resources can handle custom development.
- How important is maintenance and updates? Power Platform requires less maintenance; custom development requires more ongoing support.
Key Takeaways
- Power Platform offers 70-80% cost savings and 75% faster development compared to custom development
- Power Platform is ideal for standard business processes and rapid development
- Custom development is necessary for complex requirements and extensive customisation
- Hybrid approaches can provide the best of both worlds for complex projects
- Consider your budget, timeline, complexity, and technical resources when making the decision
