Service Overview
Everything you need to know about Web Development Company UK
Innovatrix Infotech is a DPIIT-recognised web development company serving UK businesses that need more than a pretty website. We build high-performance Next.js and React web applications that load fast, rank in search, and scale as your business grows. Our 12-person engineering team has shipped web platforms across e-commerce, SaaS, professional services, and media. Every project starts with a fixed-price proposal and is delivered in 2-week sprints with visible progress throughout. As a Google Partner and AWS Partner, we build on infrastructure that UK businesses can rely on. We use TypeScript throughout, write comprehensive tests, and deploy on AWS or Vercel with CI/CD pipelines from day one. We do not use page builders, drag-and-drop tools, or WordPress themes. Everything we build is custom code, which means it performs better, ranks better, and costs less to maintain over time.

How it works
Our process — start to finish
Discovery and Scoping
We review your requirements, audit your existing system, and define the technical scope. Deliverable: a fixed-price proposal with sprint milestones and technology decisions documented.
Architecture and Design
We design the system architecture, database schema, and UI in Figma before writing any code. You approve the technical approach and designs before sprint one begins.
Sprint Development
Two-week development sprints with a working demo at the end of each sprint. You test, give feedback, and we refine. Transparent progress throughout.
Integration and Testing
API integrations, third-party service connections, performance testing, and cross-browser QA. We test edge cases explicitly, not just the happy path.
Deployment and Go-Live
Production deployment on AWS or Vercel with CI/CD pipeline, monitoring, and alerting configured. Staged rollout with rollback capability.
Ongoing Support
Monthly retainer options covering feature development, performance monitoring, dependency updates, and bug fixes. Most UK clients continue with us post-launch.
Typical timeline: 12 weeks
Client stories
What our clients say
Honest words from people who've been through the process. No stock photos, no made-up companies.
“When two freelancers ran away with our money, we had lost all trust in agencies. Innovatrix didn't just rebuild our store — they rebuilt our confidence. Four years later, we've gone from one lakh to over one crore in revenue. They're not our vendor, they're our technology partner.”
G
Garima Ahuja
Co-founder, FloraSoul India
“We had jewellery but no digital presence. Innovatrix gave us a Shopify store that actually feels like walking into a jewellery showroom. The tiered discounts and WhatsApp integration alone doubled our repeat customers. We went from zero online orders to processing 50+ orders a day within four months.”
M
Mukesh Sethiya
Founder, Zevarly
“Before this system, our team was glued to their phones all day just answering the same questions over and over. Now those hours are back, and our customers actually get faster responses than when we were doing it manually. Rishabh and his team understood our operations deeply before writing a single line of code.”
