Preliminary work: we start with analysis and mapping of the current situation
Every creation of an online store begins with goal mapping and preparation in collaboration with the client. Based on our extensive experience and examples of multiple established online stores, we understand that a key prerequisite for achieving success is to accurately map out the business needs. Following this, we proceed to describe a solution that will help achieve those goals.
In order for the resulting online store to function efficiently within the company, we also identify the necessary integrations with existing processes. During the preparation phase, an overview is obtained of the business processes that need to be integrated with the newly established online store. Commonly used tools in the company’s day-to-day operations may include accounting and inventory management software, as well as CRM systems.
At this stage, we also assess whether and in what way artificial intelligence could support sales. We evaluate the possibilities for implementing different solutions and whether your customers expect AI solutions. We select the most suitable tools and solutions, models, and approaches – from chatbots to intelligent AI search and product recommendations.
Design: we create an attractive and user-friendly customer journey (UX/UI)
Based on the preliminary work, we create design solutions for your e-commerce store, ensuring that the customer journey is simple, inspiring, and convenient. Our experienced UX designers create a customer journey for the e-commerce store that takes into account the specific characteristics of your business and supports sales growth.
We consider that a significant portion of users make purchases from their mobile phones. Therefore, we design the e-commerce store to be user-friendly on mobile devices as well. We also have extensive experience in creating even the most complex e-commerce businesses, whether involving multiple target markets or integrating new technologies such as virtual reality or AI solutions. Unique custom solutions are precisely our strength.
Development: we build an e-commerce platform that supports sales and growth
Quality development is a critically important step when you want to digitise your business or expand your existing e-commerce store. We use the world’s leading platforms, Magento 2 and MedusaJS, to create e-commerce stores. These platforms are the most modern and widely used solutions today, allowing for easy scalability of e-commerce stores. Additionally, they offer powerful features that simplify e-commerce management and automate processes.
Our experienced team excels at writing high-quality code even for the most complex e-commerce stores. To ensure user-friendliness, we also test the solution with clients. Before launching the e-commerce store, we make sure to address any issues that arise during testing.
Maintenance & support: as a long-term partner we ensure the online store’s continuity
Post-launch support and maintenance ensure the long-term functionality and user-friendliness of your e-commerce platform. We implement necessary updates for the e-commerce platform and software, manage databases, and provide user training. We serve as your long-term software management partner, ensuring the smooth operation, security, and sustainability of your e-commerce store.
Auditing an existing store
If the store is already running, we start with an audit. We review speed, the customer journey, accessibility, SEO, security and integrations, and give you a written overview of what is in order, what needs fixing and what is critical.
The audit gives you a prioritised list of work, so you know where to put the money first.
We use the world’s leading e-commerce platforms
Adobe Commerce is the commercial edition of Magento, with B2B features and cloud hosting. It suits large stores in several markets.
MedusaJS is an open-source headless e-commerce platform built on Node.js that can be shaped exactly around your business logic.
WooCommerce is the online store solution for WordPress. It suits small and medium-sized stores where content and sales go hand in hand.
- Accessibility (WCAG)
- At the client’s request, we bring digital solutions into line with WCAG (Web Content Accessibility Guidelines). This means that the final solution is accessible to users with diverse needs.
- Security (OWASP)
- We adhere to the principles of the OWASP security standards to ensure the security of the software. By following OWASP guidelines, we are always aware of the major security vulnerabilities associated with the use of web applications.
- Web hosting
- We work with both cloud-based (cloud hosting) and dedicated server-based (dedicated hosting) solutions. We can be your partner in providing exactly the web hosting solution that your business requires.
E-commerce integrations
Content management (CMS)
We connect the store to a content management system, so marketing can manage campaigns, banners and pages without a developer.
Product information management (PIM)
All product information in one place: product cards, required fields and completeness checks. Only complete products go on sale.
Akeneo
Akeneo PIM handles product information only. We set it up by product family and connect it to the ERP and the online store.
AI search
AI-based product search understands the shopper's question, not just keywords, and finds the right product without its exact name.
Warehouse management system
We connect the online store to the warehouse management system, so stock levels, picking and delivery move between the systems automatically.

Magento, Adobe Commerce, MedusaJS and WooCommerce. If no off-the-shelf platform fits, we build the store as a custom solution.

A new logic for e-commerce advertising: the buyer’s question matters more than the keywordWhen someone searches for “a bed,” a retailer can show them an ad for beds. But when they ask AI which bed would suit two tall, light sleepers, the ad needs to address a much more specific need. According to Margus Eha, CEO of Opus, this is changing three things in e-commerce marketing at once: keywords are becoming less important, product data is becoming more important, and the final form of an ad is increasingly shaped by the buyer’s query.Read more
