What Is eCommerce Software Development?

eCommerce software development builds the storefronts, marketplaces, and order systems that power online retail. The work covers platform builds on Shopify Plus, Magento, BigCommerce, or custom stacks, headless commerce frontends, multi-vendor marketplaces, B2B portals, mobile commerce apps, and integrations with ERP, OMS, and payment infrastructure. Retailers hire eCommerce software development partners to launch new storefronts, migrate platforms, or build differentiated commerce experiences.

eCommerce Software Development Services We Ship

Shopify Plus development

We build custom Shopify Plus storefronts on Hydrogen, custom checkout extensions, Shopify Functions for pricing and discounts, and Shopify Flow automations. Themes are built mobile first and tuned for Core Web Vitals. We also handle Plus account setup, scripts migration to Functions, and Launchpad event readiness.

Headless commerce

Next.js front ends backed by Shopify, BigCommerce, or Commercetools. We wire GraphQL Storefront APIs, set up Vercel or AWS Amplify hosting, and handle the catalog, cart, and checkout flows. Edge caching, ISR, and CDN strategy are scoped early so launch traffic does not break the storefront.

Magento and Adobe Commerce

We build on Magento 2 and Adobe Commerce B2B, deliver PWA Studio storefronts, and run migrations from Magento 1. Work covers custom modules, tax and shipping logic, and Adobe Commerce Cloud deployments.

Custom marketplaces

We build multi-vendor marketplaces with vendor onboarding flows, escrow payments, commission management, dispute handling, and KYC. Stack is typically Next.js with Node.js on the API layer and Postgres for the data layer.

B2B commerce portals

B2B portals with custom catalogs, customer-specific pricing, account hierarchies, quote workflows, and approval chains. Integrations cover Salesforce, HubSpot, NetSuite, and SAP order systems.

Mobile commerce apps

We ship React Native and Flutter commerce apps, plus native iOS and Android when needed. Work covers push notifications, deep links, in-app payments, and offline catalog browsing for thin network regions.

How We Work With You

πŸ‘ Problem discovery

Discovery (Week 1)

A commerce lead runs scoping calls with your team. We capture catalog size, channel mix, payment regions, and integration list. Output is a written scope and a sprint plan.

πŸ‘ Image

Catalog and integration mapping (Week 2)

We map product data, SKUs, variants, tax rules, and shipping zones. ERP, OMS, PIM, and CRM integrations are listed with payload samples. Risk areas are flagged before code starts.

πŸ‘ Image

Sprint build (ongoing two-week sprints)

Two-week sprints with a demo every Friday. You get sprint goals, burndown, and a shared backlog. An engineering manager runs delivery and reports to your team weekly.

πŸ‘ Image

Launch, hardening, handover

Pre-launch covers load testing, security review, and a soft launch window. Post-launch covers four weeks of hardening on a fixed schedule. Code, docs, and access are handed over to your team or kept under our retainer.

Why Retailers Pick ScalaCode for eCommerce Software Development

πŸ‘ Image
  • Rate transparency

    Hourly rates run from $13 to $25. Monthly engagements run from $1,200 to $4,000 per engineer. Rates sit on the public site. No hidden margins, no surprise change orders. Scope, sprint plan, and weekly billing are written into the master agreement at signing.

  • 13+ years of commerce builds

    We have shipped Shopify, Magento, BigCommerce, and custom marketplaces since 2012. The team has seen the migration patterns, the payment edge cases, and the inventory sync failures that break weaker builds.

  • Shopify Plus Partner status

    ScalaCode holds active Shopify Plus Partner status with current project deliveries. This gives our team direct partner support, early access to features, and a documented track record on the platform.

  • IP transfer day one

    All code, designs, and assets are yours from day one. We sign IP assignment in the master agreement. No staged ownership, no buyout clauses.

  • Engineering managers run delivery

    Every engagement gets a named engineering manager. This person owns sprint planning, risk reporting, and quality. You get one point of contact, not a rotating roster.

How to Choose an eCommerce Software Development Partner

Verify platform partner status

Shopify Plus Partner and Adobe Solution Partner badges indicate qualified delivery.

Check headless commerce experience

Next.js with Shopify or BigCommerce APIs is the modern stack.

Confirm payment gateway breadth

Stripe, Adyen, Razorpay, and regional gateway coverage matters for global rollout.

Review ERP and OMS integration history

NetSuite, SAP, and custom ERP integration patterns vary widely in difficulty.

Validate performance posture

Core Web Vitals scores on past builds predict your conversion rate.

Assess B2B commerce capability

Custom catalogs, account hierarchies, and quote workflows are not standard.

Test migration discipline

Platform migrations need cutover plans, dual-write windows, and SEO preservation.

Ways to Work With Us

Dedicated commerce team (monthly)

A retained team of 3 to 8 engineers, a designer, and a QA lead. Monthly billing, two-week notice to scale up or down. Best for ongoing roadmaps.

Fixed scope build (10 to 20 weeks)

A defined milestone build with a written scope and a fixed fee. Used for storefront rebuilds, B2B portals, and marketplace launches. Change requests handled by written addenda.

Platform migration (legacy to modern)

Magento 1 to Magento 2. Magento to Shopify Plus. WooCommerce to BigCommerce. Headless cutovers from monolithic stacks. We migrate the catalog, orders, customer data, and SEO redirects with a documented switchover plan.

Commerce site rescue

A short engagement to stabilize a struggling site. Common cases include checkout abandonment spikes, broken integrations, Core Web Vitals failures, and theme rollback after a failed update. Rescue runs are scoped weekly with a written stop point.

What Clients Say

View All Testimonials

I looked around at several developers to compare costs, but they didn’t fit within my budget. Finally, I reached out to a company in India called ScalaCode. We set up several online meetings over a couple of weeks and came up with an app that did exactly what I wanted within my budget. I can confidently say that ScalaCode has been an excellent choice for me.

I have been working with ScalaCode for almost a year and half now. I have this project 4Sale, it’s a marketplace application. I contacted them for the project and we started around 2021. The company is very responsive and always take the extra mile to help you out. I highly recommend them; if you have a project, contact this company. They always respond on time even though there’s a time difference.

CEO, 4Sale

The application was basically built from scratch, and was complicated, as the software was to be integrated with a certain Medical EHR software. As the CEO of SHG, I was very pleased with the services, expertise, and support we received from ScalaCode, from the beginning directly through the first LIVE implementation.
