Service
eCommerce platforms built for performance, scalability and growth
We design, build and support ecommerce platforms for organisations who need seamless buying experiences and operational efficiency, without sacrificing performance, flexibility or integration capability.
Who this is for
You’re launching or rebuilding an ecommerce platform
Moving from a basic setup to something more scalable and commercially focused.
You need better conversion and user experience
Traffic isn’t translating into revenue due to poor UX or checkout friction.
You’re managing complex products or operations
Catalogues, pricing, fulfilment or integrations are becoming difficult to manage.
What we help solve
Practical problems we see on ecommerce programmes-and how we address them.
Low conversion despite strong traffic
Users drop off during browsing or checkout. We design conversion-focused ecommerce experiences and optimised checkout flows-higher conversion rates and revenue.
Complex or inefficient buying journeys
Poor UX creates friction for customers. We simplify product discovery, navigation and checkout-a faster, smoother purchasing experience.
Disconnected systems and manual processes
Orders, inventory and customer data aren’t aligned. We integrate ecommerce platforms with CRM, ERP and operational systems-streamlined operations and reduced manual effort.
Platforms that don’t scale with growth
Existing solutions struggle with catalogue size or demand. We implement scalable architectures suited to your growth stage-a platform that supports long-term expansion.
Over-reliance on plugins or workarounds
Technical debt builds over time. We rationalise platform architecture and build custom solutions where needed-a more stable, maintainable ecommerce ecosystem.
Why Tonic / why this approach
- Commerce-first thinkingWe design around how customers buy-not just how platforms work.
- Balance between speed and scalabilityFrom rapid launches to complex, enterprise-grade builds.
- Integration-led architectureEcommerce is part of a broader system, not a standalone product.
- Conversion-driven deliveryUX, performance and data all aligned to revenue outcomes.
- Practical, maintainable buildsReducing unnecessary complexity and long-term technical debt. This reflects a delivery approach focused on measurable outcomes and real-world implementation rather than platform features alone.

FAQs
How do we choose the right ecommerce platform?
It depends on your product complexity, scale, integrations and growth plans. We guide this during discovery.
Is Shopify or Magento better?
Shopify suits speed-to-market and operated SaaS convenience; Magento (Adobe Commerce) suits complex catalogues, B2B rules and deep customisation—we recommend based on catalogue, markets, ERP and team skills.
Can you migrate our existing store?
Yes—we migrate products, customers, orders and SEO-critical redirects with validation so checkout, stock and reporting stay trustworthy.
Do you optimise for conversion?
Yes-conversion is a core focus across UX, performance and checkout design.
Can you integrate with our systems?
Yes-ERP, CRM, payments and logistics integrations are standard.
What happens after launch?
