# Configure Centralized Multi-Company Behavior

### How to Configure Centralized Multi-Company Behavior in Muhasib ERP

### Overview

This guide will help you select the primary company and configure which masters or transactions are shared/visible across companies.

Affected forms may use primary-company masters or expose cross-company transactions. Wrong settings can mix identities, numbering, stock, accounts, tax, or reports.

### Who can do this

You need access to Global Configurations, relevant company permissions, and explicit multi-company data-governance authorization.

### Before you start

Back up the database. Inventory each company's items, contacts/parties, payment accounts/types/terms, tax, terminals, sales, purchases, roles, numbering, and reporting obligations.
