What is a B2B ecosystem?
Business apps that belong to one platform and share the account and the data, instead of being wired together through paid integrations.
Business ecosystem, integrated with AI technologies
Polish SMBs, accounting firms and agencies need one coherent platform — not a patchwork of single-purpose tools that don't talk to each other. Every extra login, every separate license and every manual integration is hours lost to operations that shouldn't be here.
Our ecosystem unifies KSeF e-invoicing, online accounting, B2B and B2C CRM, ERP, HR, project management with time tracking, online appointment booking, SMS and WhatsApp notifications and full marketing automation in one platform with built-in AI. One login, one contract, one invoice in PLN.
Built-in NIP, REGON and KRS lookup against the GUS registry, counterparty verification against the VAT white list, EU VAT validation via VIES, one-click JPK_FA exports and full alignment with the Ministry of Finance FA(2) schema — ready for mandatory KSeF e-invoicing before it goes live.
EU data centers, encryption at-rest and in-transit, GDPR-grade data protection aligned with Polish data-protection law, Polish-language support via chat, email and phone, contracts in Polish and transparent PLN pricing — all in one subscription you can reconcile like any other KSeF invoice.

The 4b2b ecosystem
The 4b2b ecosystem — Poland
The 4b2b ecosystem is a group of business apps that share one account, one company record and one customer record. You switch on only the modules you need, and anything entered once shows up everywhere else — from invoicing through contracts to timesheets.
- One login for every module, with permissions set per role.
- Company and customer details are entered once, not six times.
- One subscription, with modules you turn on as you go.
- Local tax compliance included on every market we open.
Questions about the ecosystem
Short answers to what small companies ask most often before choosing. Each one has its own page, with worked examples and the mistakes to avoid.
What is the 4b2b ecosystem?
Invoicing, accounting, CRM, ERP, HR, projects, contracts and notifications under one account, with local compliance on each market.
How does an ecosystem cut software costs?
It removes parallel subscriptions and paid connectors: replacing six separate apps typically takes 40–60 % off the monthly bill.
What does Single Sign-On mean for a company?
One person signs in once and reaches every module; when they leave, access is revoked from a single place.
How is tax compliance handled across 70 countries?
Every market has its own e-invoicing format and channel, and the ecosystem applies them from the market you selected.
