Notable Clients
Sun Group is a software house and interactive agency based in Ujście, Poland. The company operates as a hybrid development and design firm, building e-commerce platforms, B2B systems, and websites primarily for mid-market and enterprise clients across Europe. The team has delivered projects for Lenovo, TERG S.A. (15-year client), ES-System, and local government bodies including county offices. Their proprietary CMS forms the technical backbone of most deliverables, and they've built internal products like SunBox (a B2B platform launchable in 7 weeks) and SunPlayer (a multimedia management system).
Services and capabilities
Sun Group divides its work across three main buckets: e-commerce, web, and development tools.
On the e-commerce side, they build B2B sales platforms and online stores. Their B2B offerings include advanced pricing systems (dynamic rates by customer group), bulk-order functionality, ERP integration, and role-based account management. They integrate with SAP Business One, enova365, Comarch XL, Optima, Subiekt, and IFS. SunBox is their pre-built B2B platform, positioned as faster to deploy than custom builds. Online stores they describe as "fast and modern" with sales-boosting features, though specifics aren't detailed beyond their proprietary CMS foundation.
Web services span traditional websites (built on their CMS), landing pages (with legal compliance handling), and product configurators—customization tools for visualization that claim to help sell "more and faster." They also offer PIM (product information management) for handling thousands of SKUs.
In development, they've built contest and lottery platforms (with data protection integration), created SunPlayer for remote multimedia control, and most recently, an AI gift-selection assistant for Media Expert. They mention building e-learning platforms and mobile apps on an as-needed basis.
Integrations span payment providers (PayPal, Stripe, Przelewy24), shipping carriers (DHL, UPS, DPD), and ERP/WMS systems. The source notes they scale to handle real-time synchronization of product data, inventory, orders, and invoices.
Notable work
TERG S.A. has been a client for 15 years, trusting Sun Group with three online stores and a complex data management system. ES-System engaged them for a multi-workstream project: a website for clients across 100+ countries and a B2B platform integrated with their ERP. Lenovo contracted them for a gaming service with forum functionality, completed on schedule. Kon-Trade Kraina Drzwi started with an e-commerce door shop and continues to bring new projects. Starostwo Powiatowe (a county office) has hosted its websites with Sun Group for years and relies on them for departmental support. SPH Credo Business worked with them on a mobile app and website for theoretical driving tests, described as "pioneering and multistage."
Browar Czarnków (a brewery) commissioned a website blending brand history with modern design. ASTA-NET delegated all Astra Group brands' web presence and graphics to Sun Group. CORE Law Grzybowski & Pilc Attorneys partnered on contests, lotteries, and an e-learning platform handling GDPR and personal data compliance training.
How they work
The source indicates they offer free initial consulting. Their B2B platform SunBox promises delivery and launch-readiness in 7 weeks. For ongoing support, they provide flexible hourly maintenance packages and development services. After implementation, they guarantee three months of reliability with SLA-driven incident response. Engagement models appear flexible, adapted to client needs rather than rigid pricing tiers. Co-CEOs Sebastian Sowa and Michał Wiedera handle new business; contact via biuro@sungroup.pl or +48 500 150 353.
