Custom E-shop
A custom e-shop adapts to your business – not your business to the platform's possibilities.
A template solution is suitable for standard online sales. We design a custom e-shop according to your processes, customers, and growth plans – from UX and functionalities to ERP, CRM, warehouses, or other integrations.
Without the limits of ready-made solutions.
Ready for complex processes and integrations.
Designed to grow with your business.
BUXUS, Shopify Plus, or WooCommerce. We select the platform according to your business model and specific needs. We design the entire architecture and infrastructure so that the solution is ready for further growth.
From B2C cart to B2B pricing levels, ERP integrations, and real-time warehouses. For example, the solution for Slovart can handle up to 4,500 product changes daily.
A proprietary AI agent at the core of BUXUS and Shopify Plus monitors performance, conversions, and technical anomalies 24/7. You are immediately informed about problems and opportunities without waiting for a monthly report.
We have completed more than 50 expansions into the CEE and EU regions. We provide multi-currency, multi-language, and multi-warehouse solutions, including localized SEO and marketing.
The BUXUS platform has no transaction or licensing fees. Brands like Kondela, Feedo, and Slovart use it. We have completed more than 400 projects on it.
We know your business must operate without interruptions. We provide our clients with continuous support, monitoring, and stable operation of their e-commerce solutions.
Development, UX/CX, performance and brand marketing, SEO, analytics, and support 24/7. You get all key competencies under one roof, without the complicated coordination of multiple suppliers.
D2C
We design e-shops for manufacturers connected with ERP, warehouse, and production processes. We build them to handle brand growth and expansion into new markets.
International B2C
We know what it takes to sell in multiple countries. We handle languages, currencies, local price lists, warehouses, and specific functionalities of individual markets from one system.
B2B – Wholesale
We design solutions for extensive catalogs, individual pricing, order approvals, ERP integrations, and thousands of operations daily. We do not see B2B as a supplement but as a separate business process.
Commerce & Retail
We connect online sales with brick-and-mortar stores into one functional unit. Real stock levels, click & collect, returns, and loyalty programs work across all channels.

A robust solution on the CMS BUXUS, which in real-time powers a gigantic B2C and B2B ecosystem across two markets and transforms technical complexity into a perfectly seamless experience.

We get to know your business, customers, and processes. We map ERP, CRM, warehouse, and necessary integrations and propose suitable technology, architecture, UX, and e-shop design.
We program the e-shop on the chosen platform and connect it with your systems – from ERP, CRM, and warehouse through payment gateways and carriers to other tools. During development, you have an overview of what is completed and what follows.
Before launch, we test the entire purchasing process, functionality, integrations, measurement, performance, and technical SEO. We then deploy the e-shop into production and oversee its smooth start.
The collaboration does not end with the launch of the e-shop. We ensure monitoring, technical support, and further development – from optimizations and new features to additional integrations or expansion into new markets.

If we were to create a new e-shop again, we would choose ui42 again.
"We wanted to show that PSS is changing on the website as well. And not just through cosmetic changes or a change of website design. We wanted to have the new website firmly in our strategic hands and use it as a full-fledged and measurable sales channel. We are glad that we selected a company that helped us in this difficult task through a competitive process. We are looking forward to the new website and to continuing our cooperation with ui42."
ui42 is our reliable partner, with whom we always resolve all shortcomings and issues. It was the same during the server replacement, when we could fully rely on ui42, both with the selection of a new server and with the migration of all our e-shops to the new server.
When looking for a supplier for our website, we were searching for an agency that would work with us to create a cohesive team and wouldn't approach the collaboration in the typical agency-client manner. We needed the agency side to also understand our business, vision, and mission so that they could contribute equally to the development of the Voxberg website. At ui42, we met these expectations fully, as today, proposals and project briefs for further development no longer come solely from our side but also from ui42, which we highly appreciate.
"We would like to thank our colleagues from ui42 for their excellent handling of the migration to the new Feedo website, and that's not just from the perspective of technical SEO. Lazy load, next gen image loading, deleting old code, and the excellent handling of URL migration, are just a few of the things that are mainly reflected in the improvement of conversion rates, and thanks to which we have been hearing positive feedback from our colleagues and customers since the launch of the new website."
"Only a few external partners can fully keep up with the rapid growth that Dedoles has faced since the beginning of last year. Fortunately, ui42 is one of those who can handle this pace and can adapt to often rapidly changing needs. Thanks to this collaboration, the website, which is a key source of turnover, is the most stable element in our IT area."
Our long-term collaboration gained momentum in 2014 when we decided to solve the sale and distribution of our books exclusively through our own website in Slovakia. From our side, the request was to redesign the visuals and to implement B2C and B2B orders in real time - in online connection with our warehouse system. Gradually, we have gradually reached where we are today, and we take trouble-free operation for granted.

Choosing the right CMS is the foundation for the success of your project. There are many boxed and custom solutions on the market with varying degrees of customization. We have summarized and compared the most commonly used ones. So, which one is the most suitable for you?
A custom-made online shop offers numerous advantages that distinguish it from standard online shops with preset templates and out-of-the-box solutions. For example, personalized design, flexibility in any modification or new request, integrations with any ERP, payment gateway, inventory system, delivery service, and others, SEO optimization, security, and unlike out-of-the-box solutions, a custom-made e-commerce store on the BUXUS platform provides a ready environment for expansion, or functionalities tailored to your needs.
The length of the process can vary and depends on several factors, including the size and complexity of the project, client requirements, and resource availability. However, in ideal cases, we are looking at implementation from 3 to 9 months (from the signing of the contract to the deployment of the project).
Yes, of course. We will train you in managing the e-commerce store, and in addition, we provide our clients with various levels of technical support and monitoring of critical functionalities. Sophisticated SLA monitoring ensures our clients can sleep peacefully even during the most important season or during a significant peak in traffic. Our collaboration does not end with the launch of a website or online shop.
Common SaaS platforms allow for a quick start, but as the business grows, they hit their limits - whether in terms of scalability, flexibility, or costs. Shopify charges a percentage of orders, WooCommerce often relies on a number of plugins, and Shoptet has its limitations with more complex solutions.
Therefore, BUXUS offers a custom-made e-shop without transaction fees, with full control over functionality and direct integration with your internal systems. The platform also includes an AI agent that works directly with the e-shop's data and helps identify problems and opportunities before they affect performance.
The AI agent functions as an analytical layer over the e-shop.
It monitors:
On the BUXUS ecommerce platform, it works directly with data in the system's core (without cookie restrictions), while on other platforms it functions as a diagnostic tool over available data.
Result: faster problem detection and more accurate decision-making.
At ui42, we combine strategy, creativity, technology, marketing, and AI into one entity.
We build brands and visual identities, create websites and e-shops, design UX and CRO, create creative content, and deliver measurable results through performance marketing.
Our solutions are enhanced by FLUIDUM – ui42's AI intelligence, which transforms company data into a competitive advantage.
Thanks to this, you gain a partner who can cover the entire digital ecosystem of your business – from the first contact with the brand to conversion.
Don't miss out on the latest news from the world of UX, programming, analytics, and marketing.
