Altinn stack · 4b2b for Norway
Twelve integrations. One vendor.
Altinn is the digital heart of Norwegian business. 4b2b ships pre-built integrations against twelve of the most-used services — from MVA-melding to the Shareholder Registry — so Norwegian companies do not need to build ETL or adapters themselves.

The 4b2b ecosystem
Why an ecosystem instead of separate apps
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.
What is 4b2b.net?
4b2b.net is the hub of an ecosystem of SaaS applications for businesses: invoicing, accounting, CRM, ERP, HR, project management, notifications, hosting and contracts, all reachable with a single account. Each product is available in its own set of markets — for example invoicing in 73 countries, accounting only in Romania and Moldova.
What you can do with 4b2b.net
- Issue invoices in 73 countries with 4invoices.net; in Romania, straight into ANAF e-Factura
- Manage customer relationships with 4softcrm.net (HubSpot/Pipedrive alternative) in RO, IT, DE and ES
- Keep the books with 4conta.ro (Romania and Moldova) and run financial ERP with 4softerp.net (Romania)
- Manage employees, timesheets and leave with 4softhr.net and 4mystaff.net (BambooHR alternative)
- Organize projects and teams with 4myprojects.net (Jira/Asana alternative)
- Send SMS and WhatsApp notifications to customers with 4notify.net in 70 countries
- Build and publish websites with 4buildsite.net
- Host applications on VPS, cPanel or dedicated servers with 4hosting.net
4b2b.net advantages
- One account and single sign-on for every product in the ecosystem
- Invoicing in 73 countries, with ANAF e-Factura integration for Romania
- Website available in 34 languages, prices shown per market
- Transparent per-market pricing with no hidden costs or volume licenses
- Documented REST API for products such as 4invoices.net
- Servers in the European Union (Finland)

Limitations
- Not a monolithic enterprise suite — each product has a separate backend
- Each product has its own markets; some (accounting, ERP) are available only in Romania
- Outside Romania invoices are issued as PDF — no submission to government tax systems
- Native mobile apps currently unavailable — responsive web interface
How it works
- Create an account on 4b2b.net and pick the products that fit your business
- Activate each product available in your market and configure it in its own panel
- Access every application with the same account, no multiple passwords
