Launching a High-Conversion eCommerce Platform for a Polish Sports Retailer
An up-and-coming sports-inventory company in Poland had ambitious growth plans. The brand sold equipment offline and through social media and wanted to expand online but lacked the technical expertise to build an eCommerce platform. They came to Advantrix Labs with a concept: sell sporting goods across multiple regions with a conversion-focused user experience, personalized product recommendations, and a frictionless checkout.
Project Snapshot
Client profile
The client (name withheld) is one of the fastest-growing sports-equipment brands in Poland. Before engaging us, they sold products through brick-and-mortar shops and social-media marketplaces. With increasing demand and plans to enter new regions, the company realized it needed a unified online store to engage customers, provide personalized experiences, and streamline fulfillment. There was no existing web platform, only a vision and a catalog of products.
Project goal
Build an end-to-end eCommerce platform that delivers the following.
- Delivers a responsive, conversion‑focused user interface across desktop and mobile, as responsive websites achieve 11 % higher conversion rates and 15 % more engagement
- Implements a personalised product‑recommendation engine; effective AI recommendations can increase conversion rates by 15–30 % compared with non‑personalised experiences
- Provides secure authentication and authorisation, using OAuth 2.0 and JWT, and manages regional payment flows via Stripe
- Offers a smooth checkout with minimal steps and support for multiple payment methods by region
- Integrates marketing automation (email campaigns, promotions and loyalty) and delivery tracking with automated state‑machine workflows
Business challenge
The client faced multiple obstacles.
- No digital storefront: Customers purchased via in‑person sales or social media; there was no central eCommerce site. This limited reach and made it difficult to scale to new markets
- Poor mobile experience: Without responsive design, mobile visitors bounced and conversion suffered
- Limited personalization: No recommendation engine or merchandising logic to guide shoppers
- Payment and checkout friction: here was no secure online checkout, and payments had to be handled manually. This created abandonment risk and limited regional expansion
- Fragmented marketing and logistics: Sales, promotions and fulfilment were managed separately; the company had no integrated email marketing or delivery tracking
Solution
Working in close partnership with the client, Advantrix Labs designed and launched a modern, cloud-based commerce platform focused on conversion and growth.
- Conversion‑oriented UX: We built a responsive front end using Next.js and React, focusing on intuitive navigation, mobile‑first layouts and clear calls‑to‑action. Responsive design ensures the site adapts to any device, helping to increase conversions and reduce bounce rates
- Personalised AI-driven recommendations and search: 3rd party AI-powered recommendation and search optimization engine analyses user behaviour, purchase history and product attributes to suggest relevant products in real time
- Secure authentication and payments: We implemented OAuth 2.0 and JWT‑based authentication with social log‑ins, and integrated Stripe for regional payment processing. Customers can pay via preferred methods while the system handles currency conversion and tax rules
- Streamlined checkout: A single‑page checkout. Address autocompletion, saved payment methods and progress indicators keep users informed throughout the journey and its touchpoints
- Marketing automation & retention: Email campaigns, loyalty workflows, personalised promotions, abandoned‑cart reminders and order tracking state machines
- Order management & delivery tracking: Back‑end services built with NestJS manage orders, inventory and shipment status. A state‑machine integration with delivery carriers provides real‑time tracking and notifies customers when packages ship and arrive
- Analytics & insights: Data dashboards collect metrics on traffic sources, conversion funnels and product performance, enabling data‑driven optimisation
Business outcomes
By translating a simple idea into a fully‑fledged digital commerce platform, Advantrix Labs empowered the sports‑equipment brand to move beyond social‑media sales, deliver personalised shopping experiences and establish a scalable foundation for growth across Poland and new regions.
- Higher conversion and revenue: The combination of responsive design and AI recommendations produced a noticeable uplift in conversion rates. Responsive layouts, which typically deliver 11 % higher conversion rates, coupled with recommendation‑driven personalisation, translated into strong revenue growth
- Reduced cart abandonment: Seamless checkout, regional payment options and account creation reduced friction and decreased abandonment, increasing completed orders
- Expanded market reach: A multi‑language, mobile‑friendly platform allowed the brand to enter new regional markets quickly and cultivate brand awareness
- Customer loyalty: Personalised recommendations, smooth experiences and targeted promotions fostered repeat purchases and higher lifetime value. Positive mobile experiences encourage users to return: 88 % of visitors with a positive browsing experience are more likely to return
- Operational efficiency: Centralized order and inventory management, automated marketing workflows and integrated delivery tracking reduced manual work and allowed the team to focus on strategy
