Core Ecommerce Capabilities We Deliver

From AI-powered shopping to checkout optimization, these eleven capabilities cover ecommerce development end to end.

AI-Powered Shopping Experiences

AI-Powered Product Recommendations and Personalized Merchandising

Conversational Shopping Assistants and Intelligent Search

Customer Support Automation Built Into the Shopping Journey

A customer who cannot find the right product or get a useful answer from search leaves for a competitor’s store instead of digging through your catalog manually. We develop AI-enhanced ecommerce experiences including product recommendations, conversational shopping assistants, intelligent search, personalized merchandising, and customer support automation, built to improve product discovery, engagement, and conversion rather than added as a generic feature layered onto the existing catalog.

Product Discovery, Search, and Filtering

Advanced Filtering and Faceted Navigation

Intelligent Search and Product Comparison

Guided Product Selection for Growing Catalogs

A catalog that has grown past a few hundred SKUs without investing in search and filtering is asking customers to do the work a modern ecommerce platform should be doing for them. We build advanced filtering, faceted navigation, intelligent search, product comparison, and guided product selection tools that help customers find the right product faster, particularly for jewelry, fashion, electronics, and industrial catalogs where product attributes and specifications genuinely matter to the buying decision.

Product Configuration and Customization

Ring Builders, Configurators, and Bundle Builders

Interactive Product Visualization

Made-to-Order Experiences That Increase Average Order Value

A customer who wants a personalized or made-to-order product but cannot configure it online either calls your store or buys a standard version from a competitor who lets them customize it themselves. We develop interactive configurators, ring builders, product customizers, bundle builders, and visualization tools that let customers build the exact product they want, increasing both engagement and average order value for jewelry, luxury retail, furniture, and manufacturing businesses selling customizable products.

B2B Ecommerce Expansion

Customer-Specific Pricing and Wholesale Ordering

Dealer Portals and Account-Based Purchasing

ERP Integration and Inventory Visibility for B2B Buyers

A B2B buyer who cannot see their negotiated pricing, order in bulk, or check inventory online defaults to email and phone, a process that costs your team time and gives buyers less reason to stay loyal to your store over a competitor’s. We build B2B ecommerce platforms with customer-specific pricing, dealer portals, wholesale ordering, account-based purchasing, and ERP integration, giving business buyers the self-service convenience they now expect from B2C ecommerce.

Ecommerce Site Speed and Performance

Page Load Times and Core Web Vitals

Image and Asset Optimization at Scale

Performance That Protects Conversion Rates

A slow-loading product page or checkout flow costs conversions regardless of how good the design or product selection is, and ecommerce sites with large catalogs are especially prone to performance problems that accumulate as the catalog grows. We optimize ecommerce site speed and Core Web Vitals at the code and infrastructure level, including image and asset optimization at scale, treating performance as a conversion-rate factor built into development rather than an afterthought addressed after launch.

Ecommerce Modernization and Replatforming

Migrating From Shopify, WooCommerce, Magento, Wix, or Squarespace

Preserving SEO, Customer Data, and Order History

Modernization Without Business Disruption

A business that has outgrown its current ecommerce platform’s scalability, performance, or integration limitations but is afraid to migrate because of the SEO and revenue risk is stuck choosing between a limiting platform and a risky move. We plan and execute ecommerce migrations, from Shopify, WooCommerce, Magento, Wix, Squarespace, and OpenCart, preserving SEO rankings, customer data, order history, and business continuity throughout the transition rather than treating the migration as a rebuild from zero.

Customer Retention and Marketing Automation

Email and SMS Automation Connected to Purchase Data

Customer Segmentation and Loyalty Programs

Lifecycle Marketing That Reduces Reliance on New Acquisition

Acquiring a new customer costs more every year, which makes a store that has no retention strategy beyond generic email blasts increasingly expensive to run. We integrate ecommerce platforms with marketing automation solutions including Klaviyo, building email automation, SMS marketing, customer segmentation, loyalty programs, and lifecycle marketing connected directly to actual purchase behavior, improving retention and lifetime value rather than treating every customer the same regardless of their order history.

Custom Ecommerce Theme and Storefront Design

On-Brand Storefronts Beyond Default Themes

Responsive Design Built for Every Device

A Storefront That Reflects Your Brand

A default theme with your logo and colors swapped in looks like every other store running the same theme, and that similarity is exactly what makes a storefront forgettable to shoppers comparing options. We design and build custom ecommerce themes and storefronts with responsive layouts built for every device, creating a shopping experience that actually reflects your brand rather than a template with minor cosmetic changes applied on top.

Mobile Commerce Optimization

Mobile-First Design and Simplified Checkout

Fast-Loading, Touch-Friendly Product Pages

Mobile Product Discovery for On-the-Go Shopping

A checkout that takes six taps and thirty seconds to load is losing mobile customers at the exact moment they were ready to buy, and mobile now represents the majority of traffic for most consumer categories. We design ecommerce experiences optimized for mobile-first engagement, including simplified checkout, fast-loading pages, touch-friendly interfaces, and mobile product discovery, particularly for fashion, jewelry, beauty, and DTC brands where mobile conversion determines overall store performance.

Data-Driven Commerce

Customer Behavior Analysis and Funnel Optimization

Product Performance Reporting and Revenue Attribution

Inventory Insights for Growing Ecommerce Businesses

A growing ecommerce business making inventory, marketing, and product decisions without reliable data is guessing at scale, and the guesses get more expensive as the business grows. We build reporting and analytics capabilities covering customer behavior analysis, funnel optimization, product performance reporting, revenue attribution, customer segmentation, and inventory insights, giving growing ecommerce businesses the data foundation needed to make informed decisions rather than relying on intuition alone.

Checkout and Payment Experience

Streamlined, Low-Friction Checkout Flows

Multiple Payment and Buy Now, Pay Later Options

Trust Signals That Reduce Cart Abandonment

A checkout process with too many steps, unclear shipping costs, or limited payment options is one of the most common reasons a shopper abandons a cart at the exact moment they were ready to buy. We build streamlined checkout flows with multiple payment methods, including buy now pay later options, and the trust signals, security badges, clear policies, visible reviews, that give hesitant shoppers the confidence to complete a purchase.

Frequently Asked Questions About Ecommerce Development Services

Questions ecommerce founders and operations leaders most commonly ask before choosing Keyideas for an ecommerce development project of any scope.

Yes. Interactive configurators, ring builders, product customizers, and bundle builders are a core part of our ecommerce practice, particularly for jewelry, luxury retail, furniture, and manufacturing businesses selling customizable or made-to-order products. These tools increase both engagement and average order value by letting customers build the exact product they want rather than choosing from fixed variants.

Yes. We build B2B ecommerce platforms with customer-specific pricing, dealer portals, wholesale ordering, account-based purchasing, and ERP integration, giving business buyers the self-service ordering and inventory visibility they now expect. This capability is particularly valuable for manufacturers, distributors, and wholesale businesses whose B2B customers currently order by phone or email.

We work across Shopify, WooCommerce, Magento, Bagisto, and Znode, along with platform-specific tools including Ring Builder and Jewelith for jewelry ecommerce and Klaviyo for marketing automation. Platform choice depends on the business’s catalog complexity, B2B requirements, and integration needs, not a default preference for any single platform.

Yes. We plan and execute ecommerce migrations from Shopify, WooCommerce, Magento, Wix, Squarespace, and OpenCart with a documented SEO redirect map, customer data migration, and order history preservation, verified before and after cutover. A migration handled without this planning risks losing search rankings and customer trust, which is why we treat migration planning as its own dedicated phase rather than an afterthought.

Yes, though deep integration work like this is covered in more depth on our dedicated Ecommerce Integration Services page, which addresses ERP, CRM, inventory, payment, shipping, supplier, and marketplace integrations specifically. This page focuses on building and customizing the store itself; integration scope and architecture are planned as their own dedicated engagement.

Yes. We integrate ecommerce platforms with Klaviyo and similar marketing automation solutions, building email automation, SMS marketing, customer segmentation, loyalty programs, and lifecycle marketing connected directly to actual purchase behavior. This is particularly valuable for DTC, jewelry, fashion, and subscription commerce businesses where customer retention meaningfully affects profitability.

A standard ecommerce build on Shopify or WooCommerce takes 8 to 14 weeks. A B2B ecommerce platform with account-specific pricing and ERP integration takes 12 to 20 weeks. A platform migration preserving SEO and order history takes 10 to 16 weeks depending on catalog size and the number of integrations involved. Timeline is confirmed after the platform, integration scope, and B2B requirements are defined.

Projects start at $5,000 for a Strategic Foundation build covering a standard ecommerce storefront with core product discovery and mobile optimization. Next-Level Growth at $10,000 adds product configuration, marketing automation integration, or a platform migration. The Accelerated Competitive tier at $20,000 covers full B2B ecommerce platforms, complex ERP integrations, or enterprise-scale Magento and Znode builds. Enterprise Partnership at $3,300 per month provides a dedicated ecommerce developer with a single point of contact and project collaboration tools.

A senior ecommerce developer at a US agency bills at $100 to $180 per hour. A UK agency charges £80 to £150 per hour. A typical ecommerce development project costs $30,000 to $100,000 at a US agency. The same project at Keyideas falls within our $5,000 to $20,000 project tiers.

Yes. Ecommerce platforms can integrate with ERP, CRM, inventory, payment, shipping, analytics, and marketing systems to synchronize information and streamline operations. API Integration Services can support these connections, while Klaviyo Services can help with ecommerce marketing automation.
