Infrastructure software for e-commerce operations that outgrow off-the-shelf.

E-commerce looks simple from the outside — a catalogue, a cart, a checkout. But behind every storefront is a tangle of inventory feeds, order routing logic, payment reconciliation, tax rules, and return workflows that generic platforms were never designed to handle. When your product catalogue hits 50,000 SKUs, when you sell across three marketplaces and your own website, when returns run at 30% and every one needs a different workflow — that is when you need software built for how e-commerce actually operates.

Why E-Commerce Software Is Different
Off-the-shelf platforms get you to launch. Custom infrastructure gets you to scale. Here is why:
Catalogue complexity compounds. Variants, bundles, configurable products, dynamic pricing tiers, and market-specific attributes. A fashion brand selling across 4 countries needs different sizes, currencies, tax treatments, and localised descriptions for the same product. Spreadsheets and basic admin panels break at this scale.
Inventory is distributed. Your stock lives across warehouses, dropship suppliers, marketplace fulfilment centres, and retail locations. Overselling on one channel because another did not sync in time is not a bug — it is a business-ending problem at scale.
Order lifecycle is non-linear. Cancellations, partial shipments, returns, exchanges, refunds, store credits — the happy path is the exception, not the rule. Your OMS needs to handle every permutation without manual intervention.
Payment and tax rules vary by geography and channel. Different payment gateways per country, marketplace-specific commission structures, GST in India, VAT in Europe, sales tax in the US — your financial reconciliation has to account for all of it automatically.
What We Have Seen
The e-commerce businesses that scale past their first million in revenue are not the ones with the fanciest storefronts. They are the ones whose backend operations handle complexity without breaking — where inventory syncs in real time, orders route automatically, and returns process themselves. The storefront is the easy part. The operations layer is where businesses win or lose.
What We Build
01
Order Management Systems
Centralised order processing across all channels — website, marketplaces, wholesale, and retail. Automated routing based on fulfilment rules, inventory proximity, and shipping cost optimisation. Split shipments, partial cancellations, and exception handling built into the core workflow.
02
Catalogue and Inventory Intelligence
Product information management that scales — variants, bundles, dynamic attributes, and market-specific localisation. Real-time inventory sync across warehouses, dropship suppliers, and marketplace channels. Automated reorder points, stock alerts, and demand forecasting.
03
Multi-Channel Sync and Marketplace Integration
Unified product listings, pricing, and inventory across Amazon, Shopify, WooCommerce, Magento, and custom storefronts. Marketplace-specific rules for content, pricing, and fulfilment handled automatically. No more manual updates across five different admin panels.
04
Payment and Tax Automation
Multi-gateway payment processing, automatic tax calculation by jurisdiction (GST, VAT, sales tax), marketplace commission reconciliation, and financial reporting. Cash-on-delivery workflows, payment plan support, and fraud detection for markets where it matters.
05
Returns, Exchange and Logistics Engine
Automated return authorisation, condition-based routing (refund, exchange, store credit), reverse logistics integration, and restocking workflows. For markets with high return rates, this is not a nice-to-have — it is the difference between profitability and loss.
We have built e-commerce infrastructure that ships real products to real customers — not demo storefronts.
Keyphone — Dumbphone E-Commerce Platform
An e-commerce platform for the dumbphone movement — custom product pages, comparison tools, and a checkout flow that matched the brand's minimalist philosophy. Built on WooCommerce with a custom catalogue architecture, educational content integration, and conversion-optimised checkout. Proof that even niche e-commerce needs thoughtful architecture underneath.
Where We Work
We work with e-commerce businesses across markets and categories — from fashion brands managing 50,000 SKUs across multiple marketplaces, to niche D2C businesses building their first custom storefront, to wholesale distributors digitising their order pipeline for the first time. The product categories change. The operational challenges — inventory accuracy, order routing, payment reconciliation, and return management — are universal.
Our clients operate across North America, Europe, the Middle East, South Asia, and Southeast Asia. Whether you sell physical products, digital goods, or subscription boxes — we build the operations layer that lets you scale without your backend becoming the bottleneck.

Why Entexis for E-Commerce
We build the layer underneath the storefront — the operations infrastructure that determines whether your business can handle 10 orders a day or 10,000. We have seen what breaks at scale: inventory sync failures that cause overselling, tax calculations that fall apart across borders, return workflows that require manual intervention for every single item. We build systems where those problems are solved in the architecture, not in your team's daily firefighting. If you are building e-commerce infrastructure — we understand the mess underneath the clean checkout page.
Frequently Asked Questions
When should I move from Shopify to custom e-commerce?
When Shopify's limitations cost you more than a custom build — custom checkout flows, complex inventory logic across multiple warehouses, real-time pricing engines, or marketplace integrations that apps cannot handle. If you are spending more time on workarounds than selling, it is time.
Can you handle multi-warehouse inventory?
Yes. We build inventory systems that track stock across multiple warehouses, handle automatic routing based on proximity or availability, and sync in real-time with your storefront and marketplace listings.
Can you build for selling across multiple marketplaces?
Yes. We build unified backends that sync products, inventory, orders, and pricing across your own website, Amazon, Flipkart, and other marketplaces — with centralised order management and returns processing.
How do you handle payment and tax compliance?
We integrate with payment gateways (Razorpay, Stripe, PayPal) and build GST/tax calculation engines that handle multi-state or multi-country tax rules. Payment reconciliation, refund tracking, and invoice generation are built in.
Can you migrate our existing store to a custom platform?
Yes. We handle full migration — products, customers, order history, reviews, and SEO URLs. The transition is planned so there is zero downtime and no lost search rankings.
