eCommerce platforms built
to convert, retain, and scale.
Off-the-shelf platforms work well until they do not. We build custom eCommerce platforms and extend existing ones: headless commerce architecture, complex integrations, and the performance engineering that turns traffic into revenue.
eCommerce development where performance and conversion are engineering requirements
eCommerce platforms are among the clearest examples of the relationship between engineering quality and business outcomes. A 100ms improvement in page load time produces measurable conversion rate improvement. A checkout flow with one fewer step produces measurable completion rate improvement. These relationships are direct and well-documented.
Our eCommerce development practice treats performance and conversion as engineering requirements with measurable targets, not aspirational goals to be addressed after launch. Core Web Vitals targets are defined and measured from the first sprint.
When to go headless and when not to
Headless commerce delivers genuine advantages for businesses needing superior frontend performance, multi-channel commerce, or design flexibility beyond platform themes. The trade-off is real: higher development complexity and higher initial investment. We recommend headless when performance or flexibility requirements justify it, and recommend staying on Shopify Plus when they do not.
eCommerce integration: the work that determines operational reliability
The most common source of customer complaints and operational cost in eCommerce is integrations. Stock discrepancies causing overselling, pricing errors from delayed ERP synchronisation, and fulfilment delays from manual order transfer are all integration problems. We design eCommerce system integration for reliability and observability so failures surface as operational alerts rather than customer complaints.
Specialisations & capabilities
Decoupled frontend consuming commerce APIs delivering superior page performance, design flexibility, and the ability to run multiple storefronts from a single backend without the performance compromises of traditional monolithic platforms.
Custom Shopify theme development, app development, checkout customisation, and complex integrations for brands that want to stay on Shopify while extending beyond standard configuration.
Ground-up eCommerce platforms for businesses whose product catalogue structure, pricing logic, or buying process cannot be handled by configurable off-the-shelf solutions.
Connecting eCommerce platforms to ERP, WMS, PIM, 3PL, accounting software, and marketing automation creating the unified data flow that prevents stock discrepancies and fulfilment delays.
Data pipelines aggregating eCommerce events into analytics platforms, personalisation engines surfacing relevant products, and A/B testing infrastructure enabling continuous conversion optimisation.
Technical SEO and Core Web Vitals optimisation for existing platforms addressing the JavaScript bloat, image optimisation gaps, and server response issues that cause search ranking and conversion problems.
How every engagement runs
We map your product catalogue, pricing model, customer segments, and fulfilment process, identifying where standard platform configuration is sufficient and where custom development is required.
Headless vs platform-native decision, frontend performance architecture, and mobile-first UX design completed and validated before development begins.
Frontend and backend developed in parallel. ERP, WMS, and payment integrations built and tested as core project components.
Performance validated against Core Web Vitals targets before go-live. Analytics configured for data-driven optimisation from the first day of trading.

What separates eCommerce platforms that grow revenue from ones that limit it?
The eCommerce platform development decision between custom, Shopify, Magento, or headless is consequential because migration costs are significant and the chosen platform constrains what is achievable for years. The right answer depends on product catalogue complexity, pricing model, customer segment, and operational integration needs.
At Softtech IT, our Shopify development and custom commerce practice starts with a platform assessment mapping requirements against the capabilities and limitations of each option before recommending an approach. For many mid-market retailers, Shopify Plus with custom integrations is the right choice for lower total cost of ownership.
Custom eCommerce development is justified when your pricing model includes customer-specific or volume pricing; your product catalogue includes complex configurators; your buying process requires approval workflows or purchase order management; or integration requirements involve ERP and WMS systems needing real-time bidirectional data flow.
The engineering decisions that determine eCommerce conversion rate and revenue per visitor
eCommerce performance optimisation has a direct relationship with revenue. Core Web Vitals scores affect Google Shopping and organic search rankings. On mobile where 60 percent or more of eCommerce traffic arrives, the performance gap between a well-optimised and poorly-optimised page is often the difference between a completed purchase and a bounce. We address performance at the architecture stage: server-side rendering strategy, image optimisation pipeline, JavaScript bundle strategy, CDN configuration, and third-party script management.
B2B eCommerce architecture has fundamentally different requirements from B2C commerce: customer-specific pricing catalogs, company account management with multiple buyer users and approval workflows, credit account and invoicing support, purchase order capture, and product catalogue visibility rules. Standard Shopify or WooCommerce configurations handle none of these natively.
eCommerce system integration between storefront, ERP, WMS, and 3PL requires architecture that handles integration failures without cascading to customer-facing order issues. The event-driven integration pattern provides the reliability and observability that polling-based integrations do not, with dead letter queues for failed events and retry logic for transient failures.
Headless commerce separates the frontend from the commerce backend. The frontend in React or Next.js provides better performance and design flexibility. The right commerce backend depends on your requirements: Shopify as headless using the Storefront API, Commercetools for complex B2B catalogue and pricing requirements, or a custom backend for businesses whose commerce logic cannot be mapped to any platform.
B2B eCommerce requires customer-specific pricing catalogs, company account management with multiple buyer users and approval workflows, credit account support, purchase order capture, and product catalogue visibility rules based on customer segment. We design B2B eCommerce architectures handling these requirements without the performance compromises many B2B platforms accept.
eCommerce integration between storefront, ERP, WMS, and 3PL requires architecture that handles failures without cascading to order issues. The event-driven pattern with message queues provides reliability and observability. Dead letter queues capture failed events. Retry logic handles transient failures. Integration monitoring surfaces issues before they appear in customer complaints.
