Comprehensive solutions beyond the box
Arrange an online presentation of the solution
We have been building custom e-shops for 15 years. They are based on our own e-commerce platform Sellio, which we adapt to your processes – from a B2C e-shop and a B2B portal to a product configurator, a warehouse system or a web application. We connect the e-shop to your ERP and accounting system, carriers and payment gateways, and add AI features that save time for your team and your customers.
Unlike off-the-shelf solutions, you get a licence to the source code, you can change the hosting and even the system core, and you can adjust the contract and SLA. You pay no transaction fees, and there is no limit on the number of products, variants, countries or currencies. See the references of e-shops we have launched.
Translations, currencies, domains and delivery processes in one system — without data duplication.
Let orders fall automatically into the ERP system, labels are generated in logistics, invoices are sent by email to the customer. Everything happens automatically in the background. You manage the eshop by voice in the AI assistant.
In one system, you manage the entire portfolio of products, whether for B2B sales, B2C sales, AI agents or feeds for your customers.
Manage your data in the Sellio system using everyday language. The AI assistant will significantly simplify bulk edits, data enrichment and translations, and you can ask it about order or customer details anytime. Discover a smarter way of working.
A classic e-shop, a B2B zone as well as a company presentation can run on one system. Manage your data in one place, in one CMS.
Secure connection with artificial intelligence: The built-in MCP server directly connects your e-shop data with top LLM models such as Claude, Gemini or Codex. Control and analysis in human language: Get the ability to analyze sales, generate SEO texts, translations and manage the store with simple commands in natural language.
We assemble our solution like lego blocks. In this way, we can customize all functionalities according to your needs.
Our new fancy admin adapts to your screen size and includes lots of UX goodies.
Sellio enables your company to enter the world of nocode. Automate your workflow with a simple click.
You can use Sellio as a headless CMS and power your frontend or mobile applications and other systems via API.
We also specialize in visual and price configurators, which we can connect directly to production or ERP.
Our content editor allows you to work with content blocks and layout your content.
