Frequently Asked Questions
Everything you need to know about our enterprise eCommerce development services, platform choices, delivery process, and engagement models.
-
What enterprise eCommerce services does Flexsin offer?
Flexsin offers end-to-end enterprise eCommerce services including custom platform development, B2B portals, headless commerce builds, marketplace development, platform migrations, ERP/CRM integrations, performance optimisation, PWA development, and ongoing managed support.
-
Which eCommerce platforms does Flexsin specialise in?
We have certified expertise across Magento 2 / Adobe Commerce, Shopify Plus, BigCommerce Enterprise, and headless commerce stacks using Next.js, Nuxt.js, and Medusa.js. We also work with WooCommerce and Salesforce Commerce Cloud for specific client requirements.
-
Can Flexsin build a B2B eCommerce portal for our distribution network?
Yes. B2B portal development is one of our core specialisations. We build account-based storefronts with tiered pricing, credit limits, quote workflows, approval processes, bulk ordering, and real-time ERP inventory sync - tailored to wholesale and distribution operations.
-
How long does a typical enterprise eCommerce project take?
A standard storefront build typically takes 10-18 weeks. Complex B2B portals or headless builds with multiple integrations may require 4-8 months. We provide a detailed project timeline after the discovery and scoping phase.
-
Do you handle eCommerce platform migrations?
Yes. We manage structured migrations from Magento 1, WooCommerce, custom legacy platforms, and on-premise systems - covering product data, customer records, order history, and SEO URL mapping - with zero data loss and controlled downtime during cutover.
-
Can you integrate our eCommerce platform with our ERP system?
Absolutely. We build bi-directional integrations between eCommerce platforms and SAP, Microsoft Dynamics, Odoo, NetSuite, and other ERP systems - covering real-time inventory, order management, customer accounts, and financial reconciliation via REST APIs and middleware connectors.
-
What is headless commerce and when should we consider it?
Headless commerce decouples the storefront (front-end) from the commerce engine (back-end), connecting them via APIs. It's the right choice when you need sub-second performance, a highly customised UX across multiple channels, or the freedom to swap back-end services independently. It comes with higher initial complexity, so we assess the fit carefully with each client.
-
Which industries does Flexsin have eCommerce experience in?
We have active delivery experience in Fashion & Apparel, Industrial B2B, Healthcare, Food & Grocery, Consumer Electronics, Home & Furniture, Luxury & Beauty, Education, Agriculture, and Wholesale Distribution - each with category-specific commerce patterns.
-
What engagement models do you offer for eCommerce projects?
We offer Fixed-Price builds for defined scope projects, Time & Material for iterative roadmaps, Dedicated Commerce Teams for long-term embedded partnerships, and monthly Support Retainers for post-launch maintenance and continuous improvement.
-
How do you approach performance optimisation for existing stores?
We start with a Core Web Vitals audit, server response analysis, and front-end profiling to identify the highest-impact bottlenecks. Fixes typically cover image optimisation, code splitting, caching strategy, database query tuning, and CDN configuration - each tied to measurable performance targets.
-
Is Flexsin's eCommerce development PCI-DSS compliant?
Yes. All our payment integration implementations follow PCI-DSS best practices including tokenisation, secure HTTPS enforcement, cardholder data isolation, and third-party gateway architecture that keeps payment data off your servers wherever possible.
-
Can you build a multi-vendor marketplace from scratch?
Yes. We build custom marketplace platforms with seller onboarding portals, commission and payout management, dispute workflows, product approval queues, and customer-facing storefronts - on custom stacks or frameworks like Sharetribe or custom Magento multi-vendor setups.
-
How do you protect our intellectual property and data?
We sign comprehensive NDAs and IP assignment agreements before work begins, use private repositories with strict access controls, and maintain secure, encrypted development environments. Your platform logic, pricing rules, and customer data remain entirely yours.
-
Do you offer support and maintenance after the store launches?
Yes. Our Commerce Support Retainers cover platform security patches, extension updates, performance monitoring, conversion rate optimisation cycles, new feature development, and SLA-backed incident response - keeping your store stable and growing after go-live.
