Documentation
How the 4b2b.net ecosystem is organized, and where to find each product's real technical resources.
What is 4b2b.net
4b2b.net is the shared storefront and account for a family of independent SMB applications: invoicing (4invoices.net), accounting (4conta.ro), notifications (4notify.net) and hosting (4hosting.net), plus CRM, ERP, HR and other modules. Each product runs as its own standalone application, with its own login and its own documentation.
How it's organized
There is no single shared API or SDK across the whole ecosystem — each brand runs its own backend and publishes its own technical docs where relevant. The Integrations page shows how the products you actually use connect to each other.
Real API & integrations
Of the ecosystem's products, 4invoices.net publishes a documented public API for developers (invoicing and e-Invoicing). For the other products, contact support for the integration options available on your plan.
