Custom Online Stores
React, Next.js, or platform-specific builds with product search, filters, wishlists, and checkout tuned for your market.
We design and develop online stores, wholesale portals, and checkout flows that load fast, handle peak traffic, and connect cleanly to your ERP, warehouse, and payment systems.
WHAT WE DO
A pretty storefront means nothing if the cart breaks during a sale. Our commerce work covers catalog architecture, tax and shipping rules, subscription billing, and admin tools your operations team can use without calling a developer. We have shipped Shopify Plus customizations, fully bespoke React storefronts, and B2B ordering portals for distributors who outgrew spreadsheets.
OUR SERVICES
React, Next.js, or platform-specific builds with product search, filters, wishlists, and checkout tuned for your market.
Decouple your front end from Shopify, BigCommerce, or a custom backend so marketing can iterate without redeploying the whole stack.
Contract pricing, bulk SKU uploads, credit limits, and approval workflows for wholesale and distributor sales.
Multi-currency checkout, gateway failover, VAT/GST rules, and reconciliation hooks into your accounting software.
Real-time stock levels from SAP, NetSuite, or custom WMS so you never oversell during a promotion.
Core Web Vitals fixes, A/B testing infrastructure, and analytics dashboards that show where carts are abandoned.
CAPABILITIES
We pick the stack based on your catalog size, internal team skills, and how much customization you actually need.
Theme development, custom apps, and checkout extensions for brands already on Shopify.
Migrations, plugin audits, and performance tuning for WordPress and Adobe Commerce stores.
Full control over UX when off-the-shelf themes cannot support your product configurator or subscription model.
Amazon, Flipkart, and multi-channel listing sync so inventory stays consistent everywhere.
USE CASES
Size guides, lookbooks, and returns portals that reduce support tickets after the holiday rush.
Recurring delivery schedules, skip-a-week logic, and cold-chain delivery slot selection.
Search by part number, compatibility matrices, and quote-to-order flows for buyers who know exactly what they need.
Age verification, prescription upload workflows, and audit logs for compliance-heavy categories.
TECH STACK
HOW IT WORKS
We review your current platform, traffic patterns, and pain points in checkout or catalog management.
Sitemap, data model, payment flow diagrams, and wireframes signed off before development starts.
Two-week sprints with staging URLs you can share with merchandising and finance for feedback.
Production cutover, monitoring alerts, and a 30-day hypercare window for post-launch fixes.
WHY MAGNISYS
Commerce projects fail quietly — slow pages, broken promos, sync errors that show wrong stock. We load-test before go-live, document every integration for your ops team, and stay on call during your first major sale.
FAQ
Shopify makes sense if you want to go live quickly and your product catalog is straightforward. Custom builds fit when you need a complex configurator, heavy B2B pricing rules, or deep integration with legacy ERP systems Shopify cannot talk to natively. We will tell you which side you fall on after a short discovery call.
A Shopify customization with a new theme and a few integrations often runs $20,000–$45,000. A headless storefront with custom backend and ERP sync typically starts around $60,000 and can reach $150,000+ for multi-region, multi-language rollouts. We quote fixed scope after mapping requirements.
Yes. We plan 301 redirects, preserve URL structures where possible, migrate product metadata, and validate Google Search Console after cutover. Downtime is usually limited to a maintenance window of a few hours.
We integrate Stripe, PayPal, Razorpay, Adyen, and region-specific gateways. That includes webhooks for payment confirmation, failed payment retry logic, and refund flows in your admin panel.
A focused Shopify launch can ship in 8–12 weeks. Custom commerce platforms with ERP integration usually need 4–7 months depending on catalog size and number of third-party systems.
