4B Systems sp. z o.o.

4B Systems is a software house based in Warsaw with an office in Gliwice, Poland. Founded in 2014, the company builds custom web applications, mobile apps, CRM systems, e-commerce platforms, and SaaS products. Tomasz Socha is CEO. The team works across industries including legal services, e-commerce, healthcare, travel, and manufacturing—building everything from WordPress sites to Python machine learning classifiers to dedicated CRM deployments.

The company frames itself as more than just developers: they pair programming with in-house marketing support and have built and maintained several proprietary SaaS products since launch. Projects range from one-off custom applications to long-term team augmentation engagements.

Services and capabilities

4B Systems offers a broad menu: CRM systems (customer communication, orders, payments, sales automation), B2B and B2C platforms (order and payment processing, contract management, complaints), mobile applications for iOS and Android, e-commerce shops (PrestaShop builds and customization), WordPress sites, MLM systems, and online ordering systems for hospitality and small retail. They also handle integrations with Google, Microsoft, Meta, email services, SMS providers, mapping APIs, and ChatGPT.

On the development side, they work with PHP frameworks (Laravel, Symfony, CodeIgniter), Python (including machine learning with convolutional neural networks), and frontend libraries (Vue.js, Node.js, Bootstrap, React Native, Flutter, Kotlin). Database experience includes MySQL and PostgreSQL.

They also run a SaaS product line: SalesWizard (CRM), Bookable (hotel reservation system), Foodeliver (online ordering), MLMseed (direct sales platform), LegallyCRM (law firm CRM), and SolarCRM (solar installation CRM). The company offers AI chatbots for business, team augmentation (outsourced developers), and staff reinforcement on existing projects.

Notable work

Legal services is a major vertical—4B Systems has deployed LegallyCRM at law offices including Frejowski CHF, JM Adversum, JM Kancelaria Prawna, Kancelaria Prawna Fenix, Legal Media, and DM LEX. These projects involved implementation, customization, and ongoing maintenance.

Other named projects include: a machine learning clothing classifier for WearMeUp.Club (built with Uniwersytet Ekonomiczny w Katowicach), an online ordering system for self-adhesive labels at Drukarni Flexon, a ski trip reservation system for Infoski.pl, a WordPress site for OrangeTours.pl (an Albanian travel operator), and team augmentation at Bankilo (Python developers added to existing fintech project). For Hydropure Polska, they deployed SalesWizard CRM with customizations and staff training.

The company has also rebuilt CRM infrastructure for law firm LexVin, refactoring code and rewriting the frontend in Vue.js after taking over from prior developers.

How they work

4B Systems follows a structured project flow: initial consultation and documentation (mocks, technical specifications), time and cost estimate, UI/UX design with client sign-off, development, functional testing and bug fixes, deployment to client infrastructure, and post-launch helpdesk support. They also offer growth sprints for new features and optional marketing support via Facebook Ads, Google Ads, and SEO.

The company operates under NDA and handles consultations on a no-obligation basis. They emphasize that projects can be discussed before commitment.
