Ecommerce & retail
software that
converts and scales.

Checkout friction and brittle ops are the two things that kill ecommerce revenue. We build custom ecommerce software development — online stores, order management, and retention workflows — for retail and D2C brands that hold under Black Friday traffic and compound customer lifetime value after every order.

Why Entalogics for Commerce

Four things every
ecommerce development project actually needs.

Revenue and retail operations both have to win. These are the non-negotiables on every ecommerce software development engagement.

Conversion01

Every millisecond in checkout counts.

We audit abandonment triggers, eliminate checkout friction, and benchmark LCP and Core Web Vitals before the first line of code. Conversion rate optimization is built into the architecture, not bolted on after launch.

Reliability02

One source of truth across every channel.

Real-time inventory sync, consistent pricing, and intelligent fulfillment routing. When your order management system and online store speak the same language, omnichannel retail stays honest — ops and customers see the same numbers.

Resilience03

Black Friday is a build requirement, not a surprise.

Load-tested at 10x expected retail traffic, queue-based order processing, and CDN-edge architecture are standard on every ecommerce platform we ship — not afterthoughts when the site goes down.

Retention04

Post-purchase is where customer lifetime value lives.

Loyalty programs, reorder flows, and post-purchase retention workflows that turn one-time buyers into repeat customers. LTV compounds when the experience after checkout is as good as before it.

Signature case

A D2C brand's
peak-season overhaul.

A fast-growing D2C retail brand was losing 34% of carts at checkout and crashing every Black Friday. We rebuilt their custom checkout flow, order management system, and inventory sync in eight weeks — before the next peak season hit.

34% cart abandonment · site crash on peak · manual fulfillment · no retention automation

Engagement shape

Eight weeks to a
peak-ready ecommerce build.

A typical ecommerce software development engagement — conversion and retail ops improvements run in parallel from week one.

W01–02
Funnel audit + architecture
Two senior engineers map the checkout funnel, inventory data model, OMS requirements, and integration surface. Every third-party dependency — ERP, WMS, PSP — identified before code is written.
W03–05
Core build
Headless storefront, custom checkout, order pipeline. Each sprint ships a testable vertical slice with full data integrity. No stubs that need replacing before launch.
W05–07
Scale + retention
Load testing at 10x peak, fulfillment automation, and post-purchase lifecycle flows. Retention marketing infrastructure wired in alongside the core build, not after.
W08+
Launch + optimize
Phased rollout, conversion rate monitoring, iteration sprints. Retained optimization stays live from day one of launch.

Definition

What does ecommerce software development actually cover?

Ecommerce software development is building the systems behind an online store: the storefront customers browse, the checkout and payment flow, the order management and fulfillment pipeline, and the retention tools that bring customers back. For retail brands, that also means omnichannel work — keeping inventory, pricing, and customer data in sync across web, mobile commerce, marketplaces, and physical stores. It splits two ways: platform-based development on Shopify, BigCommerce, or Adobe Commerce/Magento, which ships faster on proven rails, and custom ecommerce development, headless and built from scratch, for retailers whose checkout, catalog, or fulfillment logic has outgrown what a platform can flex to. Most retailers need both at different points — a platform to launch, custom software once conversion and scale become the constraint.

FAQ

Sharp questions,
straight answers.

Both. We build on Shopify Plus when the platform's rails fit, and go fully headless — Next.js storefront, custom checkout, your own OMS — when conversion or scale needs outgrow what Shopify's native checkout allows. Adobe Commerce (Magento), BigCommerce, and WooCommerce are also in our stack for existing platforms we take over.
Yes — it's the first thing we audit. Abandonment triggers, Core Web Vitals, one-page checkout flow, and fraud friction all get benchmarked before we touch code. Our signature case took a brand from 34% cart abandonment to a +47% checkout conversion lift.
Yes. Every ecommerce platform we ship is load-tested at 10x expected traffic with queue-based order processing and CDN-edge architecture before it goes live — not discovered the hard way on Black Friday.
Yes — order management and fulfillment integrations with NetSuite, Shipbob, ShipStation, and custom WMS platforms are core to our ecommerce software development work, not a bolt-on.
Yes. Marketplace listing sync (Amazon, eBay), B2B checkout flows with negotiated pricing and purchase orders, and D2C storefronts all run through the same catalogue and order infrastructure — we scope which combination your business needs on the funnel audit call.
Fixed quote after the W01–02 funnel audit, once scope is genuinely known. The eight-week engagement above is the typical envelope for a peak-ready rebuild; platform-based builds on Shopify or BigCommerce are usually faster and cheaper than a full custom, headless build.
Our typical peak-ready rebuild runs eight weeks end to end. A platform-based store on Shopify or BigCommerce can launch faster; a fully custom, headless build with complex integrations takes longer — we give you a real timeline after the architecture is mapped, not a generic estimate.
Yes. Senior engineers only, no handover to a different team after the sale. The engineers in the W01 funnel audit are the ones shipping W08.
