Rather than building and customizing software for every new client, the team adopted a flexible, metadata-driven architecture—prioritizing configuration over coding. This allowed organizations to tailor their experience through simple, user-friendly tools.
From Custom Software to Scalable SaaS: How One Platform Evolved to Serve Many
Executive Summary
Discover how a single-purpose software application was transformed into a powerful, scalable Software-as-a-Service (SaaS) platform. In partnership with RAZR Systems, a traditional company successfully reimagined its internal tool into a multi-tenant SaaS product—capable of serving many different clients, each with unique needs, all from a single codebase. At the heart of this transformation is a groundbreaking, no-code configuration system that allows non-technical users to customize their experience—without writing a single line of code.
The Challenge
The original platform was built for just one organization, with hard-coded features and workflows tailored to their specific operations. As interest grew from similar companies, it became clear that scaling the product without a new approach would be impossible.
Key challenges included:
- Supporting multiple clients with different workflows and data requirements
- Allowing customization without relying on developers
- Ensuring performance and security across all clients
- Delivering a consistent user experience across organizations
- Onboarding new clients quickly and efficiently
The Breakthrough: A Platform Powered by Configuration
Dynamic User Interfaces — Built Without Code
With built-in "screen designers," users can now:
- Define their own data structures
- Create custom forms and layouts
- Set rules and logic specific to their business
- Design workflows tailored to their internal processes
"We stopped building screens and started building tools to let others build their own screens."
Custom Reports & Dashboards — Instantly Configurable
The same flexibility applies to reporting. Users can:
- Choose the data fields and filters they need
- Build charts, graphs, and dashboards visually
- Share insights across their team or keep them private
- Make changes on the fly, without waiting for IT
"We didn't just create reports—we created report builders. Now users answer their own questions in real time."
Built with Modern Technology
The platform runs on a future-ready tech stack, including:
- Next.js and React Native for web and mobile experiences
- TypeScript for reliable, scalable code
- tRPC for seamless data communication
- PostgreSQL with Drizzle ORM for secure and structured data storage
At the core is a Metadata Engine, defining:
- Data models and fields
- Layouts and screen configurations
- Actions users can perform
- Permissions and access levels
Everything is stored in the database and accessed dynamically, enabling real-time updates without code changes.
Enterprise-Grade Security for Every Client
- Role-based access control ensures users see only what they should
- Tenant-specific data separation ensures privacy
- Secure authentication and detailed activity logs provide peace of mind
The Business Impact
For the Company:
- Larger Market Reach: Serve many clients with one platform
- Lower Costs: 70% less custom development needed
- Faster Launches: New clients onboarded in days
- Recurring Revenue: Transitioned from one-time sales to subscriptions
For Clients:
- Total Control: Customize the platform without technical help
- Speed & Agility: Launch features and reports instantly
- Reduced Costs: No need for expensive developers
- Long-Term Value: System grows with their business
Key Takeaways
This SaaS evolution revealed powerful lessons:
- Flexibility is a Superpower: A strong metadata foundation unlocks limitless customization
- Empower Your Users: Non-technical users thrive when given the right tools
- Simplicity Wins: Guided configuration beats overwhelming flexibility
- Performance Can't Be an Afterthought: Even dynamic systems must be lightning fast
- Plan the Migration: Support legacy users with a smooth upgrade path
Conclusion: The Future of SaaS is User-Driven
By moving from custom development to configurable tools, this platform has reshaped what's possible for SaaS businesses. Clients now build their own solutions—quickly, securely, and without developers.
The result? A living, growing platform that gets stronger with every new client. Each configuration adds value for all, creating a network effect that continuously improves the system.
This is more than software—it's a smarter way to build, scale, and serve.
