Global ecommerce is projected to exceed $8 trillion in 2026. Whether you are a DTC brand launching your first mobile app, a retailer going omnichannel, or an entrepreneur building the next multi-vendor marketplace, the first question is always the same: how much will this cost to build?
The answer ranges from $15,000 for a simple mobile storefront to $500,000+ for a full-featured marketplace with AI recommendations, multi-vendor management, and real-time inventory sync. The gap is enormous because ecommerce apps are deceptively complex — behind every clean product page sits payment processing, inventory management, shipping logic, tax calculation, fraud detection, and analytics.
In this guide, we break down every cost factor involved in building an ecommerce app in 2026, covering the build vs platform debate, mobile commerce specifics, payment integrations, and B2B vs B2C cost differences.
Ecommerce App Cost Tiers
Every ecommerce app falls into one of three tiers based on features, scale, and business model.
Simple Mobile Store
$15,000 – $40,000
A single-vendor mobile store with product catalog, search and filtering, shopping cart, checkout with Stripe or PayPal, user accounts, order history, push notifications, and basic analytics. Think of it as your Shopify store but as a native mobile app with better performance and push notification capabilities. Ideal for DTC brands with 50–500 products.
Multi-Feature Marketplace
$50,000 – $150,000
A marketplace or advanced ecommerce app with multi-vendor support, vendor dashboards, commission management, AI-powered search, wishlists, loyalty programs, multiple payment gateways, real-time inventory management, shipping calculator with carrier integrations, promo codes and flash sales, reviews and ratings, and a full admin panel. The tier most funded ecommerce startups build at.
Enterprise Ecommerce Platform
$150,000 – $500,000+
A full-scale enterprise ecommerce ecosystem with ERP integration, WMS connectivity, AI-powered personalization engine, AR try-on features, multi-currency and multi-language support, subscription commerce, B2B wholesale portals, headless commerce architecture, advanced fraud detection, PCI DSS compliance, real-time predictive analytics, and omnichannel inventory sync.
Shopify vs WooCommerce vs Custom: Honest Cost Comparison
The biggest decision in ecommerce development is whether to build custom or extend an existing platform. Here is a direct cost and capability comparison across the three main options.
Shopify
Setup: $5,000 – $25,000
Ongoing: $300 – $2,000/mo
Pros
+ Launch in weeks, not months
+ Large app ecosystem
+ Handles hosting and security
+ PCI compliant out of the box
Cons
– Transaction fees (0.5–2%)
– Limited customization
– Scaling costs rise sharply
– Cannot build complex B2B flows
Best for: Standard DTC brands under $5M revenue
WooCommerce
Setup: $8,000 – $40,000
Ongoing: $200 – $800/mo
Pros
+ No transaction fees
+ Full code ownership
+ Huge plugin library
+ Flexible content management
Cons
– You manage hosting/security
– Plugin conflicts are common
– Performance issues at scale
– Requires WordPress expertise
Best for: Content-heavy stores, bloggers, small catalogues
Custom Build
Setup: $40,000 – $500,000
Ongoing: $2,000 – $8,000/mo
Pros
+ Complete control
+ No platform dependency
+ Unlimited scalability
+ Custom business logic
Cons
– Longer time to market
– Higher upfront investment
– Need ongoing dev team
– You own all maintenance
Best for: Marketplaces, complex B2B, 7-figure+ brands
Mobile Commerce App Development Costs
Mobile commerce accounts for over 72% of ecommerce sales in 2026. Building a dedicated mobile app typically delivers 3–4x higher conversion rates than mobile web, driven by push notifications, faster performance, and saved payment methods. Here is what mobile-specific development costs.
React Native App (iOS + Android)
$25,000 – $100,000A single codebase delivering near-native performance on both platforms. React Native is the sweet spot for 90% of ecommerce apps — you get one codebase, one team, and one maintenance cost, while still accessing device capabilities like push notifications, biometric authentication, and camera (for visual search or AR try-on).
Flutter App (iOS + Android)
$20,000 – $90,000Google's Flutter framework offers beautiful, highly performant UI components and slightly better animation performance than React Native. Great for brands where visual experience is a core differentiator — fashion, luxury, or lifestyle ecommerce.
Native iOS App Only
$30,000 – $80,000Pure Swift/SwiftUI development delivering the best possible iOS experience. Recommended only if your audience is >85% iOS users or you need deep iOS ecosystem integrations (Apple Pay, Live Activities, Dynamic Island).
Native Android App Only
$25,000 – $70,000Pure Kotlin development for Android. Less common as a standalone choice unless targeting markets where Android has 80%+ market share (India, Southeast Asia, Latin America).
Progressive Web App (PWA)
$10,000 – $35,000A web app installable on home screens with offline support and push notifications. Good for brands on tight budgets or who want to supplement their website rather than replace it. Conversion rates are lower than native apps but significantly better than standard mobile web.
Payment Gateway Integration Costs
Payment integration is not just adding a Stripe library — it is building a complete payment flow with error handling, retry logic, refund processing, PCI compliance, fraud detection, and a seamless checkout UX. Here is what each payment capability costs.
Stripe (Core)
$3,000 – $8,000
Tx fee: 2.9% + $0.30
Standard card payments, Apple Pay, Google Pay, webhooks for order events, refund processing, and Stripe Elements for PCI-compliant checkout. The foundation for every ecommerce app.
PayPal Integration
$2,000 – $5,000
Tx fee: 2.9% + $0.30
PayPal and Venmo checkout buttons, Express Checkout, and PayPal Credit. Still essential — 35% of US online shoppers prefer PayPal and abandon carts without it.
Buy Now Pay Later (BNPL)
$3,000 – $8,000
Tx fee: 4–6% per tx
Klarna, Afterpay, or Affirm integrations. BNPL increases average order value by 30–50% in fashion and electronics categories. Higher merchant fees but significant revenue uplift.
Multi-Currency Support
$5,000 – $15,000
Tx fee: +1–3% FX fee
Automatic currency detection, localized pricing, dynamic currency conversion, and multi-currency Stripe accounts. Essential for international ecommerce — removes checkout friction for non-USD buyers.
Subscription Billing
$6,000 – $18,000
Tx fee: +0.5% (Stripe)
Recurring payment scheduling, dunning management for failed payments, plan upgrades/downgrades, proration, and subscription analytics. Critical for subscription boxes, replenishment commerce.
Crypto Payments
$4,000 – $12,000
Tx fee: 0.5–1%
Coinbase Commerce or BitPay integration for Bitcoin, Ethereum, and USDC payments. Growing in luxury and gaming verticals. Lower fees than cards but narrow audience.
Inventory Management Integration Costs
Inventory management is the operational core of every ecommerce business — and the most common source of expensive engineering work that founders underestimate. Here is what different levels of inventory management cost to build or integrate.
Basic Inventory Tracking
$4,000 – $12,000Product stock levels, sold/available counts, low-stock alerts, and manual stock adjustments from an admin panel. Suitable for small stores with one warehouse and straightforward products (no variants).
Multi-Variant Inventory
$8,000 – $20,000Tracking stock across product variants (size, color, material), bundle products, virtual products, and digital downloads. Includes pre-order support and backorder management.
Multi-Warehouse / Multi-Location
$15,000 – $50,000Real-time stock visibility across multiple fulfillment centers, retail locations, and third-party logistics (3PL) providers. Intelligent fulfillment routing based on customer proximity and stock availability. Critical for omnichannel operations.
ERP / WMS Integration
$20,000 – $80,000Bi-directional sync with SAP, NetSuite, Oracle, or Brightpearl. Real-time purchase order management, supplier lead times, reorder automation, and financial reconciliation. Enterprise-grade inventory intelligence for high-volume operations.
Third-Party Marketplace Sync
$10,000 – $30,000Real-time inventory sync with Amazon, eBay, Walmart Marketplace, and other sales channels to prevent overselling. Centralized order management across all channels from one admin dashboard.
B2B vs B2C Ecommerce: Cost Differences
B2B ecommerce is typically 40–80% more expensive to build than an equivalent B2C store. The added complexity comes from account management, negotiated pricing, approval workflows, and integration requirements.
B2C Ecommerce
Standard checkout flow
Single buyer, instant payment
Fixed product pricing
Same price for all customers
Simple account management
Name, email, address
Basic tax calculation
State-level sales tax
No approval workflows
Buy immediately
B2B Ecommerce (adds)
Purchase order workflows
+$8,000–$20,000
Customer-specific pricing
+$10,000–$25,000
Company accounts + sub-users
+$8,000–$18,000
B2B tax & invoicing (NET 30/60)
+$6,000–$15,000
ERP/procurement integration
+$20,000–$60,000
Bottom line: A B2C ecommerce app costing $60,000 would cost $100,000–$120,000 as a B2B portal with equivalent functionality. B2B ecommerce is more expensive but the deal sizes and lifetime value are dramatically higher — the ROI math still works.
Factors That Affect Ecommerce App Cost
Here are the variables that have the biggest impact on your ecommerce app budget.
Feature Complexity
A basic catalog with checkout is fundamentally different from a marketplace with vendor management, dynamic pricing, and AI-powered search. Each advanced feature adds weeks of development time. AR product visualization, visual search, and social commerce can add $20,000–$60,000 each.
Multi-Vendor Architecture
Marketplace apps need vendor onboarding, commission structures, payout management (Stripe Connect), dispute resolution, and vendor analytics. This architectural decision adds 40–60% to total project cost compared to a single-vendor store.
AI Recommendations & Personalization
Product recommendation engines, personalized search, dynamic pricing, and customer segmentation require machine learning infrastructure. A basic recommendation system costs $10,000–$25,000. Enterprise personalization with real-time behavioral analysis costs $30,000–$80,000.
Platform Choice (Native vs Cross-Platform)
Building separate native iOS and Android apps costs 60–80% more than a single cross-platform app using React Native or Flutter. For most ecommerce apps, cross-platform delivers 95% of the native experience at significantly lower cost.
Geographic Expansion Features
Multi-currency, multi-language, localized payment methods, and region-specific tax compliance (EU VAT, India GST) add $15,000–$40,000 for markets beyond your home country. Essential if you plan to sell internationally within 12 months of launch.
Development Team Location
US agencies charge $150–$300/hour. Offshore teams charge $35–$75/hour. Codazz's blended model — Edmonton project management with Chandigarh engineering — delivers enterprise-quality ecommerce apps at 40–60% less than fully domestic teams.
Feature Cost Breakdown
Here is what each core ecommerce feature costs to develop, so you can prioritize your MVP and plan your roadmap.
Product Catalog & Search
$5,000 – $20,000Product listing pages, categories, filtering, sorting, and search. Basic keyword search is cheap. AI-powered search with typo tolerance, synonym matching, and visual search adds significant cost.
Shopping Cart & Checkout
$4,000 – $15,000Cart management, guest checkout, saved addresses, order summary, promo code application, tax calculation, and shipping rate calculation. The checkout flow directly impacts conversion rates — we obsess over every step.
Payment Processing
$3,000 – $20,000Stripe, PayPal, Apple Pay, Google Pay integration with proper error handling, retry logic, refund processing, and PCI compliance. Multi-currency support and BNPL options add to the cost.
User Accounts & Profiles
$3,000 – $10,000Registration, login (email, social, phone), profile management, order history, wishlists, saved payments, address book, and notification preferences.
Admin Dashboard
$8,000 – $30,000Order management, product management, inventory tracking, customer management, promo code creation, analytics and reporting, and content management for banners and promotions.
Push Notifications & Marketing
$3,000 – $12,000Abandoned cart reminders, order status updates, price drop alerts, personalized recommendations, and promotional campaigns. Deep linking to specific products from notifications.
Shipping & Logistics
$5,000 – $20,000Carrier integration (UPS, FedEx, USPS, Canada Post), real-time rate calculation, tracking integration, return management, and shipping label generation.

Frequently Asked Questions
How much does a basic ecommerce app cost?
A simple single-vendor mobile store costs $15,000–$40,000. A marketplace with multi-vendor support costs $50,000–$150,000. Enterprise-grade ecommerce platforms with AI, ERP integration, and omnichannel features range from $150,000 to $500,000+.
How long does it take to build an ecommerce app?
A simple store takes 2–4 months. A feature-rich marketplace takes 4–8 months. Enterprise ecommerce platforms take 8–14 months. These timelines include design, development, testing, and launch.
Should I build a native app or use React Native?
For 90% of ecommerce apps, React Native or Flutter delivers the best value — one codebase for iOS and Android at 40–60% less cost than separate native apps. We only recommend native development for apps with heavy AR/VR features or extremely custom animations.
What are the ongoing costs after launch?
Hosting and infrastructure: $200–$2,000/month. Payment processing fees: 2.9% + $0.30 per transaction (Stripe). Maintenance and updates: $2,000–$8,000/month. App store fees: $99/year (Apple) + $25 one-time (Google).
Should I start on Shopify or build custom?
Start on Shopify if you are pre-product-market-fit and need to validate fast. Build custom when you hit $1M+ revenue and need features Shopify cannot support — complex B2B, multi-vendor, or deep personalization. We help clients navigate both paths.
How do you handle product data migration?
We build custom migration scripts to transfer your product catalog, customer data, and order history from Shopify, WooCommerce, Magento, or any other platform. Migration is included in our project scope at no additional cost.
Can you integrate with my existing ERP or inventory system?
Yes. We have integrated ecommerce apps with SAP, NetSuite, QuickBooks, TradeGecko, and dozens of custom inventory systems. API integration is a core strength of our Chandigarh engineering team.
