Custom E-commerce & Retail Software Development
Stacklyn builds custom e-commerce and retail software for D2C brands, multi-brand retailers, marketplaces, and distribution businesses. We deliver headless storefronts, B2B and B2C marketplace platforms, order management and inventory systems, POS and omnichannel tooling, loyalty programmes, and merchandising analytics — built for teams that have outgrown a template-based store.
Software Challenges in the E-commerce & Retail Sector
Most retail businesses start on a hosted platform and stay there happily until one of three things breaks: catalogue complexity, order orchestration, or margin. A brand with configurable products, tiered B2B pricing, or split fulfilment eventually finds itself paying for apps that half-fit and running the remainder in spreadsheets. The threshold for custom development is rarely design — it is when the order lifecycle spans multiple warehouses, channels, and partners, and no off-the-shelf product can hold the truth about what is actually in stock and where it is going.

Problems We Solve for E-commerce & Retail Companies
Platform Limits on Catalogue Logic
Configurable products, bundles, tiered B2B pricing, and customer-specific catalogues forced into a template model that was never designed for them.
Inventory Truth Scattered Across Channels
Marketplace, website, POS, and warehouse stock tracked separately, producing oversells, cancellations, and account health penalties.
Manual Order Orchestration
Split shipments, partial fulfilment, backorders, and returns coordinated by hand across warehouses and courier partners.
App Sprawl and Rising Costs
A dozen paid plugins layered on a hosted platform, each adding load time, fragility, and a monthly bill that grows with volume.
Slow Storefront Performance
Heavy themes and third-party scripts pushing Core Web Vitals into failing territory, quietly reducing conversion on every session.
No Margin Visibility by SKU
Discounts, shipping costs, returns, and marketplace commissions never reconciled per SKU, so best-selling products may be loss-making.
Software Solutions for E-commerce & Retail Companies

High-performance Next.js storefronts with server-side rendering, edge caching, structured product data, and SEO-first architecture that scores well on Core Web Vitals under real traffic.

Multi-vendor onboarding, seller dashboards, commission and payout engines, catalogue moderation, dispute handling, and buyer-specific pricing and credit terms for B2B trade.
Order Management System (OMS)
Unified order lifecycle across channels with intelligent warehouse allocation, split and partial fulfilment, backorder handling, returns and exchanges, and courier integration with tracking.
Inventory & Warehouse Management
Real-time multi-location stock with reservation logic, bin and batch tracking, purchase orders and goods receipt, stock transfers, cycle counting, and low-stock and reorder automation.
POS & Omnichannel Retail Tools
Store point-of-sale with offline capability, unified customer profiles across online and store, click-and-collect, ship-from-store, and endless-aisle ordering from the shop floor.
D2C Mobile App & Loyalty

ERP, Accounting & Channel Integrations
Two-way integration with SAP, Tally, Zoho, and marketplace APIs including Amazon and Flipkart, keeping catalogue, pricing, stock, orders, and invoices synchronised across systems.
Merchandising & Margin Analytics
Dashboards for SKU-level contribution margin after discounts, shipping, returns, and commissions, plus cohort retention, basket analysis, and AI-driven recommendations and search.
Tech Stack We Use
Why E-commerce & Retail Companies Choose Stacklyn
Performance Is Revenue
We build storefronts where server rendering, edge caching, and disciplined third-party scripts keep Core Web Vitals green, because load time shows up directly in conversion rate.
One Source of Stock Truth
Inventory is modelled once with reservation logic, then projected to every channel — the only reliable way to stop oversells across marketplace, web, and store.
Order Orchestration That Handles Reality
Split shipments, partial cancellations, exchanges, and multi-warehouse allocation are modelled explicitly rather than patched with manual workarounds.
You Own the Platform
Custom commerce ends the per-app monthly tax and the ceiling on what your catalogue and pricing logic can express. The codebase and the data are yours.
Margin Made Visible
We reconcile discounts, shipping, returns, and commissions to SKU level, so merchandising decisions are made on contribution margin rather than gross revenue.
Migrate Without a Blackout
We run phased migrations with catalogue and customer data mapping, URL and SEO preservation with redirects, and parallel running so search rankings and orders survive the switch.
