eCommerce development that keeps your sales engine running.
Ecommerce development is complex, but it doesn't have to be painful. DEV.co provides premier ecommerce development services tailored to your business — beautiful design, powerful back-ends, and clean integrations, built by senior in-house teams.
eCommerce that's built for your brand, not borrowed from a template.
Successful ecommerce requires beautiful design, continual optimization, feature development, and testing — and a development partner who understands all of it.
At DEV.co, we build sophisticated software applications that help enterprise brands run successful ecommerce businesses. We work with you every step of the way — from initial architecture through launch and iteration — to make sure your online store is everything you need it to be.
We can customize ERP, CRM, and other solutions to fit within your existing ecommerce platform, or build a proprietary system entirely from the ground up. The result is a store that represents your brand, supports your marketing strategy, and scales with your business.
What our ecommerce developers build.
From storefront to back-office — full-stack ecommerce engineering for brands that need more than a template.
A reference ecommerce architecture.
We design around clean tier boundaries — storefront, commerce logic, payments, integrations, and data each scale independently without pulling the rest down.
Each tier is independently scalable — the same discipline whether you're on Shopify Plus, Magento, or a fully proprietary platform.
Platforms we build and customize.
We work with virtually every major ecommerce platform — and build proprietary solutions when nothing off-the-shelf fits.
Back-end customizations and admin software.
Whether you need to extend an existing installation or build entirely new tooling, we create the back-end software that runs your ecommerce operation.
Build on any platform — or build your own.
Need a full-time ecommerce developer to create a store that truly represents your brand? Our team will build on the platform of your choice — Magento, WooCommerce, Shopify, BigCommerce, and more — or create a fully custom proprietary ecommerce solution from scratch.
We work closely with your marketing and design teams to ensure the ecommerce system supports your digital marketing strategy and requirements, not just your transaction flow.
Discuss Your PlatformCart, checkout, and order confirmation — engineered clean.
Reliable checkout logic, inventory checks, and payment handling are the core of any ecommerce build. Here's a simplified view of how we structure it.
// Checkout: validate cart, reserve inventory, process paymentasync function checkout(cart: Cart, payment: PaymentMethod) { const items = await inventory.reserve(cart.items) // lock stock if (items.some((i) => !i.reserved)) throw new OutOfStock(items.filter((i) => !i.reserved)) const order = await orders.create({ cart, items }) // create record const charge = await payments.charge({ // run payment amount: cart.total, method: payment, orderId: order.id, }) await notifications.send(order, charge) // confirm to customer return { order, charge }}The same discipline — inventory integrity, payment reliability, and instant confirmation — applied across every checkout we build.
Our ecommerce development process.
A proven five-stage process that turns your requirements into a store that converts.
Planning & Analysis
Map your goals, target customers, and technical requirements. Audit any existing platform or system to identify what needs to change, integrate, or be built from scratch.
Design
Create UX/UI aligned to your brand identity and conversion goals — well-structured, engaging, and built on JavaScript and HTML5 best practices.
Development
Build and customize on your chosen platform (or proprietary), integrating ERP, CRM, payments, and any à-la-carte tools your operation depends on.
Testing
QA for functionality, performance, and compatibility across devices and browsers. Stress-test checkout, inventory sync, and payment flows before a single customer sees them.
Launch & Support
Go live with monitoring in place and a roadmap ready. We provide training and ongoing support so your team can operate and grow the store confidently.
Off-the-shelf platform vs. a DEV.co custom build.
Template solutions work fine at the start. As your brand grows, the gaps become ceilings. Here's how they compare.
| Off-the-shelf template | DEV.co custom ecommerce | |
|---|---|---|
| Brand accuracy | Generic, template-constrained | Built to your exact brand image and culture |
| Back-end logic | Plugin-limited | Custom modules and proprietary logic as needed |
| ERP / CRM integration | Limited or expensive add-ons | Clean, tested integrations from day one |
| Scalability | Hits platform ceilings | Architecture designed to grow with your volume |
| Mobile commerce | Responsive only | Cross-platform or native mobile app options |
| Ownership & control | Platform-dependent | Your codebase, your roadmap |
eCommerce software that supports your marketing strategy.
A great ecommerce store isn't just a transaction system — it's a marketing asset that works alongside your campaigns, content, and brand.
