Developer.
Stores Built to Sell.

When you hire an eCommerce developer from Devvista, you get a team that understands both the technical side of ecommerce platforms and the commercial logic behind them. Most stores leave money on the table because the checkout experience is frustrating — we build ecommerce development solutions that actually convert.

What Does Professional eCommerce Development Cover?

Most stores look the same, load slowly, and leave money on the table. Yours won't.

Professional ecommerce development goes far beyond installing a platform and uploading products. It means building a store around how your customers shop — the search and filtering they need, the checkout flow that removes hesitation, the post-purchase experience that builds loyalty, and the backend systems that let your operations team work efficiently.

It also means choosing the right platform for your specific situation. Shopify is excellent for businesses that want speed to market and a managed hosting environment. WooCommerce gives WordPress-based businesses deep flexibility and full ownership. Headless commerce architectures give high-scale retailers the performance and customization freedom that traditional platform constraints do not allow.

Our eCommerce Development Services

Every store is built around how your specific customers shop and what your business model actually requires.

01

Custom Shopify Development

Custom themes in Liquid, custom app development for functionality Shopify does not handle out of the box, and Shopify Plus implementations for high-volume merchants who need advanced checkout customization and B2B features. We do not use pre-built themes unless you specifically want to start from one as a base.

Shopify
02

WooCommerce Development

Custom product types, pricing rules, subscription billing, booking systems, wholesale pricing, and payment integrations. Full ownership of your platform and code.

WooCommerce
03

Headless Commerce

Separate the frontend from the commerce engine — complete UX control, faster performance at scale, and more design freedom than traditional platforms allow.

04

eCommerce Migration

Moving your store from one platform to another is complex when done properly. We migrate products, customer data, order history, and SEO equity — including URLs and metadata — so the transition does not cost you rankings or customer records. We have handled migrations from Magento, BigCommerce, Squarespace, and custom platforms.

05

Conversion Rate Optimization

If your store has traffic but not enough sales, we audit your funnel — landing pages, product pages, cart, and checkout — identify where users are dropping off, and make targeted improvements to recover that revenue.

Performance Optimization

An ecommerce store that loads slowly loses sales directly. We target Largest Contentful Paint, minimize JavaScript blocking, compress images, and configure CDN delivery for a Lighthouse score above 90 on mobile.

Fast

Platform to Launch.
Revenue-Ready.

Every decision is made with the goal of increasing revenue, not just building a functional store. The two perspectives are not always the same thing.

01
Step One

Platform & Architecture Decision

We start by helping you choose the right platform for your specific business model, catalog size, and growth plans. This is a genuinely important decision, and we give honest recommendations rather than defaulting to whatever we find easiest to build on.

02
Step Two

Design & UX

We design the shopping experience before building it — product discovery, product detail pages, cart and checkout flow, and account management. Mobile behavior gets as much attention as desktop because most ecommerce traffic is now mobile.

03
Step Three

Development & Integration

We build the theme or frontend, configure the commerce backend, and connect all required integrations — payment processors, shipping carriers, inventory management, email marketing, CRM, and analytics. Integrations are tested with real transaction flows, not just in sandbox mode.

04
Step Four

Performance Optimization

Our target is a Lighthouse performance score above 90 on mobile. We optimize for Largest Contentful Paint, minimize JavaScript blocking, compress and lazy-load images, and configure CDN delivery before any launch.

05
Step Five

Launch & Post-Launch

We manage the launch process including DNS cutover, payment gateway live testing, and order notification setup. We monitor the store for the first 48 hours post-launch and stay available for any issues that emerge from real traffic.

06
Step Six

Ongoing Development

Most successful ecommerce businesses are continuously improving their stores. We work with clients on a retainer basis for ongoing feature development, seasonal customizations, A/B testing implementations, and performance maintenance.

Platforms

Industries We
Build For.

Each ecommerce category has different requirements. B2B needs tiered pricing and net payment terms. Subscriptions need dunning management. We bring the right experience to each type.

Why Us Over
Anyone Else?

We are developers who have also studied conversion optimization — so we make design and development decisions with the goal of increasing revenue, not just building a functional store.

01
Conversion Logic Drives Every Decision

As a Shopify development agency and full eCommerce development services provider, we make every design and development decision with the goal of increasing revenue — not just building a functional store. We have studied conversion optimization alongside our engineering, and the two perspectives are not always the same thing.

02
We Do Not Treat Platform Limits as Boundaries

When Shopify or WooCommerce cannot do something you need, we find a way to build it — whether that means a custom app, a headless architecture, or a creative use of the platform's extensibility points.

03
Mobile Is the Primary Target, Not an Afterthought

Most ecommerce traffic is mobile and most stores are still not optimized for it. We design and test on mobile devices throughout the project, not just at the end. Our performance targets are set based on mobile metrics.

04
Honest Platform Recommendations

We help you choose the right platform for your business, not the one we find easiest to build on. If Shopify is right for your situation, we will say so. If WooCommerce or a headless architecture fits better, we will tell you that instead.

05
We Stay After Launch

Seasonal customizations, A/B tests, performance maintenance, and new feature development. Successful ecommerce businesses are continuously improving their stores, and we work with clients on a retainer basis to support that.

Straight
Answers.

No runaround. No sales speak. Just honest answers to the questions we hear most.

It depends on your business. Shopify is the easiest to manage and the fastest to launch on. WooCommerce gives you full ownership and more flexibility if you are already on WordPress. Headless makes sense for high-traffic stores with complex frontend requirements. We help you make this decision during the discovery phase.

A custom Shopify or WooCommerce store typically costs between $8,000 and $40,000 depending on the number of custom features, integrations, and the complexity of the catalog. Headless builds start around $40,000. We give a fixed-price estimate after reviewing your requirements.

Yes. We start with a conversion audit that looks at your analytics, session recordings, and heatmap data to identify where users are dropping off. We then prioritize fixes by revenue impact and implement them incrementally so you can measure the effect of each change.

Yes. We integrate all major payment gateways including Stripe, PayPal, Braintree, Square, and platform-native options. We also set up fraud detection rules, test all transaction flows in staging before launch, and configure proper error handling for failed payments.

Yes. Mobile is the primary focus, not an afterthought. We design and test on mobile devices throughout the project, not just at the end. Our performance targets are set based on mobile metrics, which are harder to hit and more important for most ecommerce businesses.

Yes. We handle migrations from Magento, BigCommerce, Squarespace, PrestaShop, and custom platforms. We migrate all products, customer records, order history, and content, and set up redirects for all changed URLs to protect your SEO rankings.
