Cloud Solutions
SpaGreen Creative is a conversion-focused eCommerce development company trusted by 8,200+ merchants across 110+ countries. Across 350+ products shipped, we have launched Shopify Plus storefronts, WooCommerce stores, headless Next.js Commerce builds and custom Laravel multi-vendor marketplaces — many of them clearing 7-figure GMV in their first year.
Whether you're migrating off Magento, launching a multi-vendor marketplace, or replatforming a Shopify store that's hitting checkout-extensibility limits, our online store development services combine senior ecommerce engineers, CRO specialists and a fulfillment-savvy PM who knows Stripe, PayPal, Klaviyo, Algolia and shipping APIs in their sleep.
Every engagement starts with a fixed-price discovery sprint, a CRO baseline (AOV, conversion rate, cart abandonment) and a written architecture decision record — so you ship a store designed around revenue, not just features.
Common eCommerce challenges we solve
Most ecommerce teams we meet aren't blocked by traffic — they're blocked by the unglamorous plumbing that quietly destroys margin (checkout, ops, ERP sync). Here's where merchants typically get stuck and how we unblock them:
- "Our store crashes on Black Friday traffic." We move you to Shopify Plus or headless Next.js Commerce on edge, add Cloudflare caching, queue-based inventory and a load-tested checkout that survives a 50× spike.
- "Conversion rate is below 1%." We run a CRO audit, fix product-page LCP, simplify the cart, add trust signals, urgency and a 1-page Shop Pay / Stripe Link checkout — typically lifting CVR 40–120%.
- "Cart abandonment is 80%." We add Klaviyo flows, browse + cart abandonment SMS, exit-intent offers and Stripe Link autofill so the funnel stops leaking.
- "We can't integrate with our ERP." We build bi-directional sync to NetSuite, SAP, Odoo, ERPNext or Tally — products, stock, orders, customers and refunds reconcile in real time.
- "Shipping rules are a nightmare." We replace fragile zone-based rules with ShipStation, Easyship or Shippo, add real-time carrier rates, branded tracking and automated label printing.

step 02
Storefront & Checkout (Week 3–10)
UI design, product pages, cart, 1-page checkout, payments, search, content models and CMS — shipped on a staging URL with weekly demos so marketing can preview every Friday.
step 03
Integrations & QA (Week 11–13)
ERP / 3PL / accounting sync, tax, shipping rates, Klaviyo flows, load testing, Core Web Vitals tuning, accessibility audit and a clean cutover to your live domain.
