Frequently Asked Questions
What types of custom SharePoint development does EPC Group provide?
We build custom SPFx web parts, application customizers, field customizers, command sets, Power Apps solutions, Power Automate workflows, custom APIs, Teams integrations, and full SharePoint intranet solutions. All development follows Microsoft best practices and is built for long-term maintainability.
What is SPFx and why should we use it for SharePoint development?
SharePoint Framework (SPFx) is Microsoft's modern development model for SharePoint Online. It uses React/TypeScript, runs client-side, and integrates natively with Microsoft 365. SPFx is the recommended approach because it's fully supported, works with modern sites, and provides the best performance and security.
When should we use Power Apps instead of custom SPFx development?
Power Apps is ideal for business-led solutions with standard forms, simple workflows, and rapid prototyping (days to weeks). Custom SPFx development is better for complex UI requirements, performance-critical applications, deep integrations with external APIs, and solutions requiring fine-grained control. We help you choose the right approach based on complexity, maintenance, and cost.
How long does a typical SharePoint development project take?
Simple SPFx web parts take 2-4 weeks. Medium-complexity solutions with Power Apps and Power Automate workflows typically take 4-8 weeks. Full intranet builds or complex application development range from 8-16 weeks. We provide detailed timelines after a discovery session.
How much does custom SharePoint development cost?
Costs depend on complexity and scope. Simple web parts start around $10,000-$25,000. Mid-range solutions with workflows and integrations range from $25,000-$75,000. Enterprise intranet projects and complex applications can range from $75,000-$250,000+. We provide fixed-price proposals after requirements gathering.
How does EPC Group handle governance for custom SharePoint solutions?
We implement ALM (Application Lifecycle Management) with CI/CD pipelines, automated testing, staging environments, and approval workflows. All solutions include documentation, admin guides, and training. We also establish coding standards, security reviews, and update procedures for long-term maintainability.

Frequently Asked Questions
What is the SharePoint Framework (SPFx)?
SPFx is Microsoft's client-side development model for SharePoint Online and SharePoint Server. It uses TypeScript and React. It is the only supported way to build custom web parts and extensions in modern SharePoint — classic add-ins are deprecated.
Can you convert our InfoPath forms to Power Apps?
Yes. InfoPath is retired. We convert InfoPath forms to Power Apps as part of SharePoint migrations or as standalone projects. Power Apps forms connect to SharePoint lists and support complex conditional logic, multi-screen flows, and approval routing.
Can you replace our SharePoint 2013 workflows?
Yes. SharePoint 2010 and 2013 workflows are retired. We rebuild them in Power Automate — with better reliability, Teams notifications, and native connection to hundreds of external services. Migration typically takes 1–4 weeks per workflow depending on complexity.
How do you price SharePoint development projects?
Simple web parts and Power Apps forms start at $5,000–$15,000. Complex intranet builds or multi-system integrations run $50,000–$200,000+. We provide fixed-fee quotes for clearly scoped projects and time-and-materials for exploratory or agile engagements.
