What We Build

Five solutions for modern ecommerce.

From custom storefronts and headless architectures to marketplace platforms and analytics — every system we build is designed for commercial performance first and technical elegance second. Neither is optional.

01

Custom Storefront Development

We build custom ecommerce storefronts that are fast, brand-accurate, and conversion-optimized — using Shopify with custom Liquid themes, WooCommerce with custom plugins, or fully custom-built frontend applications connected to a commerce backend via API. Every design decision is made with the goal of getting more visitors to complete a purchase, not just displaying products.

02

Headless Commerce Architecture

Headless commerce separates the frontend from the commerce backend, giving you complete control over the customer experience while keeping your product catalog, inventory, and order management in a reliable backend system. We build headless storefronts using Next.js or Nuxt.js, delivering the performance and flexibility that high-growth ecommerce businesses need to differentiate their experience.

03

Marketplace Platform Development

We build multi-vendor marketplace platforms where third-party sellers can list products, manage inventory, process orders, and receive payouts. These platforms include vendor onboarding, product catalog management, order routing, commission calculation, and fraud prevention — the full marketplace infrastructure required to run a platform business model.

eCommerce Automation and Operations

We build automation systems that handle inventory replenishment, order routing to the right fulfillment center, return processing, customer segmentation for marketing, and financial reconciliation — giving your operations team capacity to focus on the exceptions that actually need attention.

eCommerce Data and Analytics Platforms

We build data platforms that aggregate your ecommerce data — orders, customer behavior, inventory, marketing attribution, and financial performance — into a unified analytics layer that helps your team make better decisions about product assortment, pricing, and marketing spend.

Why eCommerce Brands Choose Devvista
"We make engineering decisions through the lens of commercial metrics — conversion rate, AOV, repeat purchase rate."

There are a lot of software shops that say they do ecommerce. Here is what actually makes the difference when you are building for commercial performance.

01

Commercial metric focus

We understand that ecommerce is a business model with specific commercial metrics — conversion rate, average order value, repeat purchase rate, and customer acquisition cost. We make engineering and design decisions through the lens of these metrics, not just technical correctness. A checkout flow that converts at two percent when it should convert at five percent is a business problem, and we treat it as one.

02

Full-stack ecommerce perspective

We have experience with the full ecommerce stack — from the frontend experience through the commerce platform and the operational systems behind it. This end-to-end perspective means we understand how decisions in one layer affect the others, which prevents the integration problems that arise when different teams build different pieces in isolation.

03

Mobile-first by default

We build mobile-first because most ecommerce traffic is mobile, and most ecommerce stores are still not properly optimized for it. Performance targets are set against mobile metrics. We measure and improve load time, interaction responsiveness, and visual stability before declaring any page complete.

Tech Stack

Technologies we use in ecommerce builds.

For ecommerce applications, we choose technology where performance and conversion are primary requirements — not afterthoughts. Every layer of the stack is chosen with commercial outcomes in mind.

Our Process

How we build ecommerce software that converts.

eCommerce projects begin with your customer, not your tech stack. Commercial metrics and architecture decisions are agreed before development starts — not discovered mid-project.

Talk Through Your Project
01
Customer and Conversion Discovery
We begin by understanding your customer — who they are, how they shop, what they expect from the experience, and where your current store is losing them. This customer and conversion focus shapes the design and development decisions that follow.
02
Platform Architecture & Integration Design
Commerce platform selection, headless architecture design, integration with ERP and fulfillment systems, and analytics tracking plan are agreed before development begins.
03
Agile Development with Conversion Testing
Development follows agile sprints with conversion rate as a first-class metric. Checkout flows, product pages, and search experiences are tested with real user behavior in mind.
04
Performance Optimization & QA
Core Web Vitals, mobile performance, and conversion flows are optimized and tested before launch.
Core Web Vitals verified
05
Launch & Post-Launch Iteration
Post-launch, we support the iteration process. Real user behavior in the first weeks after launch tells you more about what to optimize than any amount of pre-launch planning.
FAQ

Questions we hear every time.

Straight answers. No deflection. No sales pitch.

eCommerce development typically refers to building a store on an existing platform like Shopify or WooCommerce. eCommerce software development covers the full spectrum — from platform implementations to custom headless architectures, marketplace platforms, and the operational and analytics software that runs behind the store. We do both.

Headless makes sense when you need performance and design flexibility that a traditional platform theme cannot provide, when you are managing content across multiple storefronts from a single backend, or when your traffic scale requires a frontend that can be served from a CDN edge network globally. For most early-stage stores, a well-built Shopify or WooCommerce theme is the right starting point.

Yes. Multi-vendor marketplace development is a specific service we offer. The complexity of a marketplace platform is significantly higher than a single-brand store, particularly around vendor onboarding, payout management, and dispute handling.

We address performance at the source — optimizing images, minimizing JavaScript bundles, implementing server-side rendering for key pages, configuring aggressive CDN caching, and addressing the specific Core Web Vitals metrics that affect both user experience and search rankings.

Yes. ERP and fulfillment integration is standard in our ecommerce work. We connect your store to your inventory management, order routing, and shipping systems so orders flow automatically without manual intervention.
