Ecommerce Software Development Company

Q: How much does custom ecommerce development cost?

$15,000–$40,000 for a D2C store. $40,000–$100,000 for a headless platform. $80,000–$200,000+ for a multi-vendor marketplace. $60,000–$150,000 for B2B with ERP integration.

Q: How long does it take to build a custom ecommerce platform?

D2C Shopify store: 6–10 weeks. Headless or B2B: 14–20 weeks. Multi-vendor marketplace: 20–30+ weeks. Timelines include discovery, design, development, testing, and deployment.

Q: Should I build custom or use Shopify?

Shopify is ideal for standard D2C. Build custom when you need multi-vendor, complex B2B pricing, custom fulfilment logic, or unique commerce experiences templates cannot support.

Q: Can you integrate with our ERP, WMS, or CRM?

Yes. We connect SAP, NetSuite, Microsoft Dynamics, Salesforce, ShipBob, and ShipStation via REST APIs, webhooks, and EDI connectors. Integration is scoped in detail during discovery.

Q: What ecommerce businesses do you work with?

D2C brands, multi-vendor marketplace operators, B2B distributors, retail chains, and subscription companies from seed-stage to $100M GMV enterprises.

Q: Do we own the source code?

Yes, completely. All source code, design files, documentation, and IP belong to you from Day 1. Full repository access throughout. No lock-in, no exit penalties.

Q: How do you handle peak traffic like Black Friday?

Auto-scaling cloud infrastructure, CDN-delivered assets, database read replicas, queue-based order processing, and load testing at 10x expected peak before every major sale.

Q: Can you build a mobile app for our store?

Yes. React Native or Flutter apps with full catalogue, cart, wishlist, push notifications, and checkout. Mobile apps increase retention 25–40% vs mobile web.

Q: How do you improve conversion on an existing platform?

We audit GA4, heatmaps, and checkout funnels to identify drop-off points, then systematically improve checkout flow, page speed, mobile UX, and product discovery through A/B testing.

We design and build custom ecommerce platforms, D2C stores, multi-vendor marketplaces, and B2B commerce solutions engineered for conversion, performance, and long-term growth. Every platform is built mobile-first, headless-ready, and scalable from day one, with delivery outcomes we own end-to-end.

Ecommerce Software Development Consultation

Ecommerce software development consultation is the process of assessing your business model, product catalogue, customer acquisition strategy, technology stack, and revenue goals, producing a platform blueprint and delivery roadmap before a single line of code is written. A structured ecommerce consultation typically takes 1–2 weeks and produces a platform specification covering tech stack, integration architecture, and conversion baseline metrics.

Deorwine's consultation process covers business model analysis (D2C, marketplace, B2B, subscription), platform selection, conversion funnel mapping, technology stack decision, third-party integration planning, and scalability architecture. We give ecommerce businesses a clear, cost-effective roadmap so you know exactly what you're building, what it will cost, and how long it will take.

Business Model Assessment

We evaluate your D2C, B2B, or marketplace model against your revenue targets, fulfilment capacity, and customer acquisition channels before making architecture decisions.

Conversion Audit

We map your customer journey from discovery to checkout — identifying where friction, speed, and UX failures are costing you revenue before a single redesign decision is made.

Technology Roadmap

We recommend the right platform (custom, Shopify, headless), tech stack, third-party integrations, and scalability plan specific to your market, traffic volume, and product complexity.
