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.

A guide to Israel's invoice-clearance era.
Israel's mandatory e-invoice clearance model — the חשבונית ישראל allocation number rolling out from 2024 — reshapes every sale, VAT return, and audit trail. This guide follows the company lifecycle: formation through the Companies Registrar, daily operations and global SaaS billing. 4b2b does not connect to the ITA or request allocation numbers; its general-purpose tools are described below.

Israel's compliance layer
Invoice clearance, VAT and the shekel — what to know.
Israel's invoice-clearance mandate means every B2B and B2G transaction needs a real-time allocation number from the ITA before the buyer can claim input VAT. That single requirement rewires invoicing, accounting, and audit workflows. Here are the four key pillars.
ITA-CLEARITA invoice clearanceחשבונית ישראל: mandatory allocation number from the Israel Tax Authority for invoices above the threshold — rolling out progressively from 2024.
VAT-18VAT 18 %Standard rate raised to 18 % in 2025; periodic PCN874 return filed with the ITA; zero-rate applies to qualified exports.

4b2b ecosystem for Israeli businesses
Each module subscribes on its own brand domain — billing, support, and licensing live there. They are general-purpose tools and do not connect to the Israel Tax Authority.

Technologies we use
The modules offer a REST API, webhooks, PDF invoices and e-mail and SMS sending. There are no integrations with Israeli authorities; the local standards listed are informational.

For accountants, lawyers, and consultants
Accounting firms and advisors can use the general-purpose modules for invoicing and record keeping. ITA clearance, VAT and Registrar filings are done directly with the authorities.
Accounting firms
Client PDF invoices and financial records in one place; ITA clearance is handled outside 4b2b.
Law firms
Fee PDF invoices and an invoice archive; company-formation filings are done with the Registrar.
Tax advisors
Use the invoice archive as a source for your own VAT analysis; PCN874 returns are filed with the ITA, not from 4b2b.
Tech agencies
PDF invoices for EU/US clients; confirm the VAT treatment with your advisers.
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.
