What We Build

Every type of web application, engineered to perform.

Enterprise Web Applications

Scalable, secure systems for large businesses: multi-tenant platforms, internal portals, workflow automation, and data management tools built for thousands of concurrent users.

SaaS Platforms

Multi-tenant SaaS products with subscription billing, role-based access control, onboarding flows, and analytics dashboards. Built to acquire, retain, and expand.

Progressive Web Apps (PWAs)

Offline-capable, installable web apps that feel native on mobile and desktop. Ideal for field teams, customer-facing tools, and anywhere unreliable connectivity is a concern.

Ecommerce & B2B Portals

Custom storefronts, B2B ordering platforms, and headless commerce builds integrated with ERP, inventory, and payment systems when Shopify or WooCommerce isn't enough.

Customer-Facing Dashboards

Real-time dashboards, client portals, and analytics interfaces built with chart libraries, WebSocket connections, and secure API integrations.

Legacy Modernisation

Incremental migration of older systems to modern stacks by refactoring monoliths into services, migrating from on-premise to cloud, and updating tech debt without disrupting operations.

Global Delivery, North America Experience

Built for clients worldwide, with proven North American delivery.

KometCode delivers web applications for clients in Canada, the US, South Africa, UAE, India, and globally. North American engagements often require provincial and state tax rules, payment gateway compatibility, PIPEDA and US data privacy compliance, and bilingual (EN/FR) support. We configure these capabilities by default when needed.

  • Canadian GST/HST and US sales tax calculation built in
  • Canadian payment gateways (Moneris, Stripe Canada, Square)
  • PIPEDA-compliant data handling for Canadian clients
  • EN/FR bilingual support for Quebec and federal requirements
  • EST/CST timezone overlap for daily collaboration

Case Study

KometCode redesigned a Windsor vape retailer's BigCommerce storefront (50% sales increase in 3 months), then built a convenience retailer's store from scratch — including local SEO, Google Business Profile, and social media. Both brands moved to online ordering with Canada-wide delivery.

Frequently Asked Questions

KometCode builds enterprise web apps, customer-facing portals, SaaS platforms, ecommerce storefronts, progressive web apps (PWAs), and internal web tools using React, Next.js, Angular, SvelteKit, Node.js, Python, and .NET.

A focused MVP typically takes 8–14 weeks. Larger enterprise platforms with complex integrations run 4–6 months. We define clear milestones and phases during discovery so you always know what's coming next.

Off-the-shelf SaaS forces your workflow to fit the product. Custom development builds the product around your workflow — giving you full control over features, integrations, data, and scaling without paying per-seat licensing that grows with your team.

Yes. KometCode takes on modernisation projects, legacy code refactors, and platform migrations. We audit the existing codebase, identify risks, and propose a phased migration or rebuild plan.

Cost depends on scope, complexity, and integrations required. KometCode delivers web applications at significantly lower rates than most local agencies because of our distributed team in Ahmedabad and Windsor, without sacrificing quality. Contact us with your requirements for a scoped estimate.
