Ecommerce Development Guide
Frequently Asked Questions
A single-vendor store with a mobile app and admin panel typically starts around $25,000 to $40,000. Multi-vendor marketplaces with vendor dashboards, logistics and AI features range from $60,000 to $150,000+. We scope every project in a free discovery call and give you a fixed-price quote before any work starts.
The number of platforms (web, iOS, Android), the business model (single vendor, multi-vendor, B2B), third-party integrations (payments, shipping, ERP, CRM), custom design, and features like real-time tracking, loyalty programs or AI recommendations. Scope and timeline matter more than anything else.
Yes. We start with an MVP that covers the features your customers need on day one, then add modules in planned releases. That keeps the first launch affordable and lets revenue fund the roadmap.
Hosting, payment gateway fees and app store accounts are paid directly by you. Optional maintenance plans cover updates, monitoring, security patches and new features, usually 15 to 20 percent of the build cost per year.
An MVP storefront usually ships in 8 to 12 weeks. A multi-vendor marketplace with mobile apps takes 4 to 6 months. We work in two-week sprints with a demo at the end of each, so you see progress from the first fortnight.
If we start by mid-year, yes. We prioritise checkout, catalogue and payments first so the store can take orders early, then add features while it is already live.
Your product catalogue (or a sample), brand assets, the payment and shipping providers you use, and a decision-maker available for a weekly review. We handle everything else, including store listings.
For some stores Shopify, WooCommerce or Magento are the right call and we build on them. For marketplaces, B2B flows or heavy customisation, a custom build is faster to evolve and cheaper to run at scale.
Discovery and scoping, UX and UI design, sprint-based development, QA on real devices, launch, then growth support. You get a dedicated project manager, a shared backlog and a staging environment throughout.
React, Next.js and Vue for storefronts; React Native, Flutter, Swift and Kotlin for apps; Node.js, Laravel and Python on the back end; headless commerce (Shopify Plus, Magento, Medusa) where it fits. Cloud on AWS or Google Cloud.
Yes. Every sprint ends with a demo and a build you can click through. Feedback goes straight into the next sprint, and nothing is a surprise at launch.
Every project includes a warranty period for fixes. After that, maintenance plans cover monitoring, updates, security and new features, with response times agreed in writing.
PCI-DSS compliant gateways (Stripe, PayPal, Razorpay, Adyen), tokenised card storage, encrypted data in transit and at rest, role-based admin access and regular dependency audits. We never store raw card numbers.
Yes. We build on auto-scaling cloud infrastructure with CDN-backed catalogues, cached product pages, queued order processing and load testing before big events.
We implement consent management, data export and deletion flows, cookie controls and privacy-by-default settings, and document how customer data moves through the system.
You do. All source code, designs, accounts and data belong to you, handed over with documentation at every milestone.
Yes. We connect stores to SAP, NetSuite, Odoo, Salesforce, HubSpot, Zoho and warehouse systems through APIs, so stock, orders and customer records stay in sync.
Yes. Vendor onboarding and KYC, individual storefronts, commission rules, split payouts, vendor analytics and dispute handling are all part of our marketplace builds.
Personalised recommendations, visual search, dynamic pricing, demand forecasting, AI chat support and automated product descriptions. We pick the ones with a measurable effect on conversion and retention.
Yes. We migrate catalogues, customers, order history and SEO URLs from Shopify, WooCommerce, Magento or custom platforms with redirects in place, so rankings and repeat customers are not lost.
