What retail and eCommerce software development covers
Storefronts, marketplaces and the order systems behind them.
- What is retail and eCommerce software development?
- Retail and eCommerce software development builds the storefronts, marketplaces, store systems and order platforms that run modern retail. It covers builds on Shopify Plus, Magento, BigCommerce or custom stacks, headless frontends, multi-vendor marketplaces, B2B portals, mobile commerce apps, and integrations with POS, ERP, OMS and payment infrastructure.
Retail and eCommerce software we build
Platform choice follows your catalog, channels and team, and we ship on Shopify Plus, headless and Magento.
Shopify Plus development
We build custom storefronts on Hydrogen, checkout extensions, Shopify Functions for pricing and discounts, and Flow automations.
Headless commerce
Next.js frontends on Shopify, BigCommerce or Commercetools, with edge caching scoped early so launch traffic does not break the store.
See web application developmentMagento and Adobe Commerce
Magento 2 and Adobe Commerce B2B builds, PWA Studio storefronts and Magento 1 migrations.
Custom marketplaces
We build multi-vendor marketplaces with vendor onboarding, escrow payments, commissions, disputes and KYC.
B2B commerce portals
We build customer-specific catalogs and pricing, account hierarchies, quotes and approval chains, all synced to your order systems.
Mobile commerce apps
We build React Native and Flutter shopping apps for iOS and Android, with push, deep links, in-app payments and offline catalog browsing for thin networks.

Start on Shopify Plus unless you have a reason not to. Go headless when the storefront itself is the differentiator.
| Shopify Plus | Headless (Next.js) | Magento / Adobe Commerce | |
|---|---|---|---|
| Best for | Most D2C brands that want hosting handled for them | Brands whose storefront experience is the product | Complex B2B catalogs and teams already on Magento |
| Build effort | Lightest of the three | Heaviest, since the storefront is custom | Between the two |
| Who runs hosting | Shopify | You, on Vercel or AWS | You, or Adobe Commerce Cloud |
| Flexibility | High inside Shopify's rules | Full control of the frontend | Full control, more to maintain |
| Where it falls short | Edge cases outside Shopify's model | Higher build and upkeep cost | Heavier hosting and upgrade work |
Migrating platforms or launching a new storefront?
Talk to us about catalog size, integrations and your launch window before you commit budget.
Try Style: virtual try-on and size advice for fashion retailers
Retailers add a Try This On button through the Shopify app, the WooCommerce plugin or a JavaScript SDK, without writing code. Shoppers get a recommended size and a photorealistic try-on from one photo, and each try-on is tracked through to add to cart.

eCommerce development process, from discovery to a store that takes orders
Two-week sprints with a demo every Friday, and one engineering manager who owns delivery.
The commerce stack we work in
Chosen per project, based on your catalog, channels and the systems you already run.
Three ways to start a commerce project
Code, designs and assets belong to you from day one on every model.
Fixed scope build
A defined milestone build with a written scope. Used for storefront rebuilds, B2B portals and marketplace launches.
Best for a storefront or marketplace launch with a clear brief.
Dedicated commerce team
A retained team of engineers, a designer and a QA lead works with you, with two weeks' notice to scale up or down.
Best for an ongoing roadmap after launch.
Platform migration
We move catalog, orders, customers and SEO redirects with a written switchover plan.
Best for Magento 1 to Magento 2, or Magento to Shopify Plus.
Secure checkout and customer data handling
We scope payment edge cases and inventory sync failures in week one, before they can break a launch.
PCI DSS
We build checkout to PCI DSS, with tokenized gateways so card data never touches your servers.
GDPR
We handle customer and order data under EU rules for European shoppers.
ISO 9001:2015
Our delivery and quality process is certified to this standard.
IP from day one
IP assignment is signed in the master agreement, so you own everything outright with no buyout clause.

Retail software development FAQs
We will answer any other question on the call.
How much does eCommerce software development cost?
Every build starts with a free discovery sprint. A web storefront or B2B portal starts from $11,999, a mobile commerce app from $9,999 and an enterprise commerce platform from $24,999. Catalog size, integrations and the platform set the fixed quote.
Should we use Shopify, Magento or a headless build?
Start on Shopify Plus unless you have a reason not to. It suits most D2C brands and is the quickest of the three to build. Go headless on Next.js when the storefront experience is the product, at a higher build and upkeep cost, and choose Magento or Adobe Commerce for complex B2B catalogs or a team already running it. Our eCommerce development page covers each platform option in more detail.
Can you connect our POS, ERP and inventory?
Yes. We connect POS systems, NetSuite, SAP, Microsoft Dynamics and custom OMS platforms through REST, SOAP or middleware. Order, inventory, customer and pricing syncs are mapped in week two, so stock levels match online and in store.
How do you handle peak traffic?
We load test against your expected peak before launch, cache catalog and content pages at the edge, and queue order writes so checkout keeps working under load. On Shopify Plus, Shopify scales the hosting. Headless and Magento builds run on autoscaling infrastructure sized during discovery.
Can you add AI product recommendations and search?
Yes. We add AI product recommendations, typo-tolerant semantic search on Algolia, Elasticsearch or Typesense, and shopping assistants that answer from your catalog and help docs. Each feature is measured against your current conversion and search exit rates.
Can you migrate our store without losing SEO?
Yes. We map every old URL to its new one with 301 redirects, carry over titles, meta descriptions and structured data, and keep catalog URLs stable where the platform allows. The switchover plan is written before code starts, and we watch Search Console for crawl errors after launch.
What happens after launch?
Every build includes four weeks of hardening. After that, a monthly retainer covers support, feature work and platform updates, or we hand everything to your team.
Do you sign an NDA and IP assignment?
Yes. A mutual NDA before discovery and full IP assignment in the master agreement. All code, designs and assets are yours from day one.
