Find out moreUX/UI design for conversion
On Tap delivers bespoke UI/UX designs that reflect your brand identity while optimising for both conversion and retention. With over 19 years in eCommerce, we have a strong track record of delivering conversion-optimised Shopify website designs across various industries.
We start with in-depth discovery and analysis of business goals, brand identity, and key customer segments. Our UI/UX specialists transform insights into intuitive designs that reflect your brand identity and facilitate seamless shopping across all devices. We specialise in complex product configurations, crafting streamlined interfaces that simplify selection and purchasing - reducing friction and driving customer loyalty.
Shopify Mobile App development
On Tap designs and develops high-performance native mobile apps and Progressive Web Apps (PWAs) that seamlessly sync with your Shopify store, delivering a fast, intuitive, and engaging shopping experience. From browsing and purchasing to tracking orders and receiving personalised offers, our apps enhance convenience and drive loyalty.
Our apps are built for speed, responsiveness, and a frictionless shopping journey across all devices. Advanced features like push notifications, AI-driven recommendations, AR product previews, and integrations with digital wallets and loyalty programs provide a cutting-edge solution tailored to your needs.
End-to-end Shopify speed optimisation
Complex integrations and customisations can slow your Shopify store, negatively impacting user experience, SEO, and conversions.
On Tap takes a holistic approach by combining customer journey analysis with a detailed technical audit. We identify where speed issues disrupt the customer experience - such as delays during product browsing or checkout - and prioritise areas for improvement.
Our technical audit uncovers root causes such as unoptimised themes, bloated code or redundant apps. We then implement targeted optimisations to boost site speed, with transparent reporting to track progress.
Expert Shopify conversion rate optimisation
Cart abandonment and low conversion rates are persistent challenges for Shopify store owners.
On Tap tackles these issues with a data-driven approach, leveraging heatmaps and other user behaviour analysis techniques to pinpoint performance bottlenecks causing lost sales.
Using these insights, we develop actionable strategies and assess their effectiveness through A/B testing to eliminate friction and improve the shopping experience, driving measurable increases in conversions and revenue.
Professional Shopify B2B solution
B2B purchasing is complex, involving multiple stakeholders who prioritise efficiency and cost-effectiveness. That is why our specialists design UX solutions tailored to different user groups, ensuring a personalised shopping experience that meets unique needs.
Our solutions include diverse B2B functions such as customer-specific catalogues, tiered pricing and multi-user accounts while seamlessly integrating with ERP, CRM, and inventory systems to streamline operations.
For businesses serving both B2B and B2C customers, we develop hybrid solutions that unify B2B and B2C, ensuring a smooth front-end experience while integrating efficiently with back-end systems.
Smooth Shopify migration
On Tap guarantees a smooth, accurate, and disruption-free migration to Shopify from any platform, including Magento, WooCommerce, BigCommerce, and other systems.
Platform migration is complex and comes with risks - but with On Tap's expertise and 100% success rate, we offer a smooth transition with minimal downtime, preserving data integrity, design consistency, and SEO rankings while optimising site performance.
