Custom e-commerce solutions that boost your sales, optimize customer experience, and streamline your operations.

E-Commerce Website - mobil öncelikli tasarım

Overview

E-commerce is no longer just a sales channel. It's the primary revenue source for many businesses. A well-designed e-commerce website sells your products 24/7, optimizes customer experience, and automates your operational processes. But a successful online store requires far more than simply listing products.

Ready-made e-commerce platforms (off-the-shelf platforms) can be attractive for a quick start. But as your business grows, commission rates, customization limitations, and platform dependency become serious obstacles. A custom-coded e-commerce site fully adapts to your brand, scales effortlessly, and offers lower total cost of ownership in the long run.

At Svart Agency, we don't build e-commerce sites from templates. Every project is custom-built for your brand. You can pick a platform theme and upload products, but if you want full control over design, performance, and integrations, custom development is the only real solution. From payment flows to shipping, marketplace sync to SEO infrastructure — everything runs by your rules.

Your e-commerce site's visual design and user experience directly impact conversion rates. To optimize critical points like cart flow, product filtering, and checkout page design, check out our UI/UX Design service.

Why Custom E-Commerce?

Ready-made e-commerce platforms offer a quick-start advantage. You don't deal with servers, updates, or security patches; you pick a theme and upload your products. But as your business grows, questions start to emerge: why can't I make the design changes I want? Why am I paying extra for every new feature? Why is my page speed so slow?

A custom-coded e-commerce site is designed from scratch based on your business's sales model, product structure, and customer experience goals. There's no unnecessary module bloat — everything from checkout flow to shipping integration is under your control.

Whether you're launching your first e-commerce site or migrating from an existing platform, custom development adapts to businesses of every size. Start with a small product catalog and scale as you grow. No platform dependency, no escalating monthly fees, no commission cuts. Your investment stays fully under your control.

Want to combine your corporate website and e-commerce site? We can integrate both on the same infrastructure. For corporate site needs, check out our Web Design service.

Payment & Shipping Integration

We integrate with licensed payment providers to ensure secure transactions. From virtual POS systems to alternative payment methods, we determine the most suitable payment infrastructure for your project together. Commission rates and terms vary by provider, so we recommend the most advantageous option for your business.

Payment Infrastructure

Virtual POS Integration

Stripe, PayPal, Square, and all major payment processors

Installment Plans

Credit card installment options and custom payment plans

Secure Payments

PCI DSS compliant, 3D Secure verification, SSL encryption

Alternative Payment

Bank transfer, cash on delivery, digital wallets (Apple Pay, Google Pay)

Shipping Integration

Multiple Carriers

FedEx, UPS, DHL, and local carrier API integrations

Automatic Tracking

Automated notifications from order confirmation to delivery via SMS and email

Weight/Volume Calculation

Automatic shipping cost calculation, free shipping thresholds

E-Invoicing

We can also integrate e-invoicing and digital invoice solutions into your e-commerce site with accounting software integrations.

Marketplace Integration

Marketplaces like Amazon, eBay, and Etsy have massive organic traffic, and ignoring these channels entirely is not wise. But building your entire sales strategy around marketplaces is not sustainable either. Commission rates, platform fees, and lack of brand control directly impact your profitability.

We build solutions that combine both strategies. You sell directly to consumers (D2C) through your own e-commerce site, while your inventory, pricing, and order data stay synchronized with marketplaces in real-time. One dashboard to manage your own store and all marketplace channels.

The biggest challenge in multi-marketplace management is inventory synchronization. Even a few seconds of delay can result in overselling, which platforms penalize heavily. Our custom architecture handles inventory sync in real-time.

E-Commerce SEO Infrastructure

SEO for e-commerce sites is far more complex than for corporate websites. Hundreds of product pages, category structures, filters, and variants. If not managed correctly, they lead to duplicate content issues and wasted crawl budget in Google's eyes.

Ready-made platforms often claim to be "SEO-compatible," but this usually just means you can edit meta titles and descriptions. The real problem runs deeper: category filters generate thousands of parameterized URLs, variants confuse Google with incorrect canonical tags, and unnecessary JavaScript in template code slows down page speed.

E-commerce SEO infrastructure included in every project

  • Product schema markup: price, stock status, and customer rating visible directly in Google search results
  • Category hierarchy and breadcrumb configuration
  • Canonical URL management: preventing duplicate content on filter and sort pages
  • Automatic alt-text and WebP/AVIF format optimization for product images
  • Automatic XML sitemap updates: new products reported to Google within seconds
  • Core Web Vitals optimization: sub-second page loading with Next.js SSR
  • Clean XML product feeds compatible with Google Shopping

Technical SEO infrastructure creates a strong starting point. However, sustainable organic growth in e-commerce also requires regular content production and a keyword strategy.

Security & Legal Compliance

Security in e-commerce is far more critical than in corporate websites. Your customers' credit card information, personal data, and order history must be protected. A single security breach causes not only financial loss but permanent damage to customer trust.

Plugin vulnerabilities commonly found in WordPress-based WooCommerce sites, which allow malicious content injection, are eliminated in custom-coded sites since no third-party plugins are used.

  • SSL/TLS encryption securing all data transfers
  • PCI DSS compliant payment flow: credit card data is never stored on your server
  • Layered protection against SQL injection, XSS, and CSRF attacks
  • No third-party plugins: attack surface kept to a minimum
  • GDPR compliant cookie consent, privacy policy, and explicit consent mechanisms

Legal requirements

Running an e-commerce site comes with serious legal requirements. GDPR compliance, cookie consent management, terms of service, return policy management, and data processing agreements. We integrate all of these into the project architecture from day one.

GDPR compliance and standard legal page templates are included in all our projects. We recommend working with a lawyer for the final content of legal texts.

Optionally, we can integrate AI-powered product recommendation systems, chatbots, or customer behavior analytics into your e-commerce site. These solutions increase sales while personalizing the customer experience.

E-Commerce Website Pricing: 2026 Cost Guide

The first question from businesses looking to build an e-commerce site is usually about budget. Prices vary widely because every project has different scope, product count, and integration needs. That's why we use project-based pricing instead of fixed packages.

Factors that determine e-commerce pricing

  • Product count and variant structure: a 50-product store vs a 5,000+ product catalog require different architectures
  • Payment integrations: number of payment gateways, installment plans, alternative payment methods
  • Shipping integrations: number of carriers, automatic tracking, weight-based pricing
  • Marketplace integrations: Amazon, eBay synchronization
  • Multi-language and multi-currency support: essential for international commerce
  • Custom modules: B2B order panel, subscription system, CRM/ERP integration

Every project is designed from scratch based on your business needs. Instead of monthly subscriptions, commissions, and plugin fees from off-the-shelf platforms, you get a one-time investment in infrastructure you fully own.

With ready-made platforms, you pay monthly subscriptions plus commission on every sale. When you calculate the 3-year total cost of ownership, custom development proves more economical in the long run.
