BitBag

BitBag is a Wrocław-based eCommerce development firm specializing in Sylius, PrestaShop, and related platforms. The company is part of the Cyber_pixel Venture group, which also owns Sylius and maintains ongoing influence over its technological direction. BitBag has completed over 150 eCommerce projects across B2C, B2B, and multi-vendor marketplace models since its founding, working with retailers including Mytheresa, Carrefour, Decathlon, Notebooksbilliger, and Adyen.

The firm employs what it describes as the top 3% of available specialists—it recruits heavily but only brings on 5% of candidates (1 in 20). Its NPS score stands at 64%. Team members speak multiple languages and bring deep expertise in Sylius, PrestaShop, Symfony, Shopware, Pimcore, and Ergonode. The company holds Sylius Global Partner status and is an official vendor/partner for Sylius, PrestaShop, Shopware, Symfony, Ergonode, Ibexa, and Pimcore.

Services and capabilities

BitBag's core offering splits into three main areas: eCommerce platform development, system integrations, and advisory work.

For platform development, the firm builds B2C stores, B2B platforms, multi-vendor marketplaces, and custom eCommerce applications. Work typically centers on Sylius and PrestaShop, though Shopware projects appear in case studies as well. The firm also handles migrations—notably from Magento 1 to Sylius, and WooCommerce to Sylius—and recently introduced a PrestaShop-to-Sylius migration tool designed to minimize risk and maintain store continuity during the transition.

Integrations form the second pillar. BitBag connects eCommerce platforms to external systems including PIM (Pimcore, Ergonode), CMS (Ibexa, Sulu), microservices, middleware, and payment gateways. The source names specific integrations completed: Adyen payment plugin, Mollie payment gateway integration, User.com plugin, and Imoje payment gateway. On the data side, the firm handles bulk migrations (the source mentions "many millions of users" for Mytheresa) and ongoing synchronization—one case study notes 120,000 products synchronized with ERP in one minute.

The consulting arm includes Sylius Consulting, a dedicated service for audits, performance optimization, team training, and architectural guidance. An eCommerce store audit covers architecture analysis, code quality review, backend and frontend performance evaluation, database query analysis, cache and server configuration, and integration review (ERP, PIM, CRM, WMS). Audit duration typically runs 2–3 weeks for smaller stores, 3–6 weeks for complex B2B projects with multiple integrations. The firm also offers training workshops, project readiness workshops, and support for Sylius 2.0 upgrades. The Sylius 2.0 upgrade service includes platform audit, migration planning, test environment preparation, implementation, and post-upgrade optimization.

Notable work

Mytheresa (luxury fashion) involved data import/export, migration of millions of users, and platform built for unlimited flexibility and scalability. Carrefour's Planeta Huerto (grocery) used Sylius with Pimcore integration, custom blog implementation via a Sylius CMS plugin, and Adyen/Aplazame payment connections. For Albeco (B2B search), BitBag built a system synchronizing 120,000 products from multiple warehouses in one minute, with an advanced product search engine.

P24 (e-grocery in Belarus) saw +400% increase in online sales, +250% increase in mobile traffic, and +70% faster page loading time post-implementation. Jast USA (video games) migrated from Magento to Sylius with a custom regional pricing system and VueJS frontend. Clickable Automotive moved from Magento 1 to Sylius with advanced search, product availability notifications, and single-page checkout. Artera (lighting) upgraded from Sylius 1.2 to 1.11, gaining easier feature rollout, admin panel automation, and advanced product search. Elvi built a mobile and web eCommerce app on Sylius with custom API layer, ERP fulfillment system, and CRM integration. Agro-Efekt (B2B) integrated SAP, multi-inventory management, and a custom search engine supporting a million products.

Payment integrations are a particular strength: BitBag built the Adyen all-in-one plugin (11 payment methods, refunds, easy addition of new methods) and the Mollie integration (described by Mollie's Lead Technical Partner Manager as "the best possible Payment Service provider within the Sylius platform").

How they work

Engagement models are not explicitly detailed in the source beyond "consulting" and "outsourcing" mentions. One case study references a client proposing "a form of cooperation" that BitBag agreed to, and another notes the firm staffing projects with dedicated Symfony developers. Pricing for Sylius Consulting is determined individually based on scope, project scale, integration count, and architectural complexity. Sylius 2.0 upgrade costs are also custom-quoted. The source emphasizes individual assessment of business needs before pricing; no fixed rates are published.

Communication appears frequent and hands-on. Client testimonials mention "daily check-ins," availability across time zones, and "patience" in explaining requirements and planning. One client notes BitBag's ability to coordinate alongside external agencies and developers.
