E-commerce website development cost depends on catalog complexity, checkout rules, integrations and whether you need custom workflows beyond standard cart flows. Kode Builder does not use a one-size-fits-all price. We help small and growing businesses define the smallest useful first phase, identify what can wait and receive a written estimate before development begins.
This guide explains modules, team composition and what typically changes the estimate. Kode Builder does not publish a custom-development rate card. After discovery we send a written estimate with modules, timeline and exclusions. Compare build paths in our Shopify vs custom e-commerce guide, then see custom e-commerce development for delivery. How quotes differ is covered on the cost planning hub.
Currency and Market Assumptions
- Primary currency: USD; INR equivalents for Indian entities
- Delivery: India-based engineering for US, UK, EU, APAC and domestic merchants

- Payment context: Stripe, Razorpay or similar — gateway fees excluded
- Content: Product copy, photography and SEO content excluded unless scoped
Included and Excluded Scope
Typically included:
- Discovery, sitemap and technical specification
- Responsive storefront (PLP, PDP, cart, checkout)
- Admin panel for catalog, orders and promotions
- One payment gateway integration
- Order confirmation emails
- QA, staging and production deployment
- 30–90 day post-launch defect window
Typically excluded:

Typical E-commerce Modules
| Module | Description | MVP? |
|---|---|---|
| Catalog & search | Categories, filters, PDP, inventory flags | Core |
| Cart & checkout | Guest/account checkout, one shipping method | Core |
| Payments | Single gateway, refunds in admin | Core |
| Order management | Status workflow, email notifications | Core |
| Promotions | Coupons, simple discounts | Often MVP |
| Customer accounts | Orders, addresses, wishlists | Often MVP |
| Shipping integrations | Carrier APIs, rate shopping | Phase 2 |
| Multi-vendor | Vendor onboarding, commissions, payouts | Marketplace scope |
| Reviews & UGC | Ratings, moderation | Phase 2 |
| Analytics & reporting | Sales dashboards, exports | Light MVP |
Team Composition
- Product / project lead — scope, milestones, merchant workflows
- UI/UX designer — storefront and admin flows
- 2× full-stack engineers — catalog, checkout, admin, integrations
- QA engineer — checkout, payment and order regression
- DevOps — CI/CD, CDN, staging and production
Marketplace builds add a backend specialist for payout logic and vendor portals.
Typical Timeline
| Phase | Duration | Output |
|---|---|---|
| Discovery | 2–3 weeks | Scope, integrations list, estimate |
| Design | 3–5 weeks | Storefront + admin UI |
| MVP build | 10–16 weeks | Catalog, checkout, admin, payments |
| QA & launch | 2–3 weeks | Go-live, handover |
D2C storefront MVPs often ship in 4–6 months; marketplaces commonly run 7–12 months.
What typically changes the estimate
Estimates follow scope, not a published rate card. Most stores start in one of three planning phases. We confirm the right starting point during discovery and send a written estimate before development begins.
| Store type | Usual planning phase | What typically drives effort |
|---|---|---|
| Small catalog D2C | Focused first phase | Standard checkout, one gateway |
| B2B / D2C with integrations | Focused first phase or Business MVP | ERP hook, custom pricing rules |
| Subscription / replenishment commerce | Business MVP | Recurring billing logic |
| Multi-vendor marketplace | Business MVP or Full operational platform | Vendors, commissions, basic payouts |
| Full marketplace platform | Full operational platform | KYC, moderation, advanced payouts |
| Production hardening | Full operational platform | Performance, tests, peak traffic prep |
Focused first phase launches catalog, cart, checkout and order admin. Business MVP adds integrations and operating tools. Full operational platform covers marketplaces, peak traffic and hardening. See custom e-commerce development for how Kode Builder delivers these phases.
Cost Factors
- Catalog complexity — variants, bundles, configurable products
- Pricing rules — contracts, tiers, geo pricing, B2B quotes
- Checkout flows — guest-only vs accounts, multi-step, tax engines
- Integrations — ERP, 3PL, CRM, accounting (each adds weeks)
- Marketplace mechanics — split payments, vendor dashboards, disputes
- Performance requirements — flash sales, CDN, search at scale
- Design customisation — template vs bespoke brand experience
Hosting and Maintenance
- Cloud hosting (AWS) — billed by AWS and grows with campaigns, catalog traffic and redundancy
- CDN & search — CloudFront, Algolia/OpenSearch costs scale with traffic (paid to those vendors)
- Payment fees — per-transaction; not part of the development estimate
- Maintenance — quoted separately for bugs, security patches and small features
- Peak season support — optional on-call before major sales events
Phased MVP Approach
Phase 1 — Launch store: Core catalog, cart, checkout, one payment and shipping method, order admin, basic promotions.
Phase 2 — Operate: ERP/3PL sync, advanced promotions, reviews, customer accounts, analytics.
Phase 3 — Scale: Marketplace vendors, international tax, performance tuning, mobile app or PWA enhancements.

Frequently Asked Questions
When workflows, integrations or pricing logic exceed platform limits and the ROI clears custom build cost. Our comparison guide walks through decision criteria.
Small CSV imports are often included. Legacy ERP migrations with data cleansing are scoped separately — volume and quality drive effort.
Yes — we design headless-friendly APIs so a future app reuses checkout and catalog services. See our mobile app cost guide.
