[ Custom eCommerce development, marketplace platforms and shopping apps ]
An online store is judged on two numbers: how fast it loads and how much of the cart survives to payment. Everything else — catalogue depth, design, integrations — only matters through those two. Techtaru Digital is an eCommerce development company delivering custom eCommerce development, marketplace platforms, shopping apps and the integration work that connects them to your ERP, warehouse and couriers.

Vendor onboarding and KYC, commission rules, vendor dashboards and payouts, ratings, disputes and centralised quality control. Covers B2B marketplace development, B2C marketplace development and Amazon-like marketplace development where you need vendor-managed inventory at scale.
Cart persistence across devices, reservation logic, shipping and tax calculation at cart, discount stacking rules and recovery flows.
Custom extensions for Shopify, Magento, WooCommerce and OpenCart where a feature does not exist or the available plugin conflicts with your stack. Stores already on that platform are served by our OpenCart specialists.

an honest read on build versus replatform versus integrate, plus a funnel analysis of your current store if one exists.
products, variants, pricing rules, inventory ownership and integration map defined before code.
category, product and checkout screens tested on mobile first, since that is where most traffic and most drop-off lives.
staging store early, Lighthouse and CWV checks enforced in CI on every pull request.
SEO-safe cutover, analytics and funnel instrumentation, then conversion experiments once real traffic arrives.
Integration is where most eCommerce projects overrun, so we scope it as its own workstream:
Platforms: Shopify and Shopify Plus, Magento 2 and Adobe Commerce, WooCommerce, OpenCart, Medusa and Saleor for headless. Frontend: Next.js, Nuxt, React with SSR on category and product pages. Backend: Node.js, Laravel, PHP, .NET. Search: Algolia, Elasticsearch, Typesense. Mobile: React Native, Flutter, Swift, Kotlin. Data: MySQL, PostgreSQL, Redis. Infrastructure: CDN edge image transformation, autoscaling, performance budgets enforced in CI.
Pick the platform for your constraint, not your preference. Shopify wins on time to market and operational simplicity, and loses when your pricing or fulfilment logic is unusual. Magento and Adobe Commerce suit large catalogues and complex B2B rules at the cost of hosting and maintenance overhead. WooCommerce suits content-led brands already on WordPress. Headless makes sense when you serve several frontends or need deep frontend control — and adds cost without benefit for a single-channel store. We give this assessment before quoting a build, because the honest answer is sometimes that your current platform is fine and only the integrations need work.
Speed is revenue, and it is measurable. Google's Core Web Vitals — LCP, INP and CLS — are both a ranking input and a reliable proxy for conversion. A headless build is not automatically fast; it is fast when you budget for it. Practically: server-side rendering on category and product pages, image transformation at the CDN edge, deferred third-party tags, and treating every new marketing script as a performance cost requiring approval.
Structured data earns the rich result. Product, Offer, AggregateRating and BreadcrumbList markup per Schema.org is what produces price and review stars in search. It is cheap to implement at build time and tedious to retrofit across thousands of URLs.
Replatforming is an SEO project as much as a build. URL mapping and 301s, preserved structured data, title and meta parity, and a crawl comparison before and after cutover. We treat migration SEO as a delivery workstream with its own acceptance criteria.
Fixed scope for defined stores and integrations; dedicated squads for marketplace and platform programmes; retainers for maintenance, support and peak-season readiness. Teams needing ongoing capacity hire dedicated eCommerce developers instead.
Indicative cost: a Shopify or WooCommerce store with custom design and standard integrations typically starts around $6,000–$18,000. Custom eCommerce development and headless builds generally run $20,000–$60,000. Multi-vendor marketplaces start higher and are phased, because vendor onboarding, payouts and dispute handling are each substantial modules. Timelines: platform store, 5–9 weeks; custom or headless build, 10–16 weeks; marketplace, 4–8 months.
If you are comparing eCommerce development companies, ask each where inventory truth will live and how they will hold your Core Web Vitals after launch. We answer both in the first call, at no cost.
Platform stores with custom design typically start around $6,000–$18,000. Custom and headless builds run $20,000–$60,000. Marketplaces cost more and are best phased. Integration count is the biggest single driver.
