2. Setting Up a Multi-Company Structure in Odoo

2.1. Creating Companies and Branches in Odoo

Odoo provides a flexible architecture that allows users to define parent companies and create branches under them. This structure helps maintain separate records for each company while leveraging shared resources such as product catalogs and contacts. Here is how to create a new company in Odoo:

1. Go to the Settings App: Navigate to the settings module in Odoo.
2. Select “Manage Companies”: Click on the Manage Companies option, which provides an overview of existing companies in the database.
3. Create a New Company: Click the Add button to define a new company. Fill in the necessary details such as:
   • Company Name
   • Address
   • Country
   • Phone Number
4. Save and Confirm: Once all details are entered, click Save to create the new entity.

2.2. Defining Main Companies vs. Branches

Odoo distinguishes between main companies and branches based on how the entities interact and share resources. Understanding this distinction is essential for setting up the right structure:

• Main Company: The central entity that controls overall settings like the chart of accounts, taxes, and currencies.
• Branch: A sub-unit of the main company that operates under its financial rules but can have distinct operational attributes (e.g., separate locations or unique journals).

There ar some key differences between main companies and branches:

1. Accounting and Financial Data: The main company’s chart of accounts, taxes, and fiscal periods apply to all branches.
2. Data Visibility: Main companies have visibility over all branch transactions and data. However, branches can only view their own data.
3. Hierarchical Control: Users at the main company level can access reports, bills, and invoices for all branches, while branch users are limited to their specific branch data.

Step 3: Adding Branches to a Parent Company

To add a branch to a main company, follow these steps:

1. Go to the Main Company’s Page: In the Manage Companies view, click on the main company’s name.
2. Select the “Branches” Tab: This will show a list of existing branches.
3. Click “Add a Line”: This option allows you to add a new branch under the main company.
4. Enter Branch Details: Specify the branch’s address, phone number, and other unique details.
5. Save and Confirm: Once the branch information is complete, save and close the record.

There is no limit to the number of branches that can be added to a parent company in Odoo, making it scalable for complex business structures.

5. User Access and Security Control for Multi-Company

Managing user access and permissions is a critical component of a multi-company setup in Odoo. As businesses grow, maintaining data security and restricting access to sensitive information become more complex. In a multi-company environment, Odoo provides granular control over user permissions, ensuring that each employee can only access the data relevant to their assigned company or branch.

5.1. Restricting User Access Based on Company Hierarchy

In Odoo’s multi-company configuration, you can define permissions at both the company and branch levels. This allows managers to control access to data such as customer records, inventory details, and financial reports. Here’s how to effectively set up user access control:

1. Navigate to User Settings:
   • Go to the Settings app and click on Users & Companies, then select Users.
2. Assign Company Access:
   • Select the user you want to configure and click on their profile. In the Allowed Companies field, choose the specific companies or branches they should have access to.
3. Set Access Rights:
   • Determine whether the user should have read-only or full access to the selected companies. You can assign roles such as Manager, User, or Accountant based on their job function.
4. Apply Security Rules:
   • Utilize security groups and rules to further refine access, such as restricting specific views or documents within a company. This can help ensure that sensitive information is only accessible to those with the appropriate level of clearance.

5.2. Best Practices for Managing Permissions

Implementing a well-thought-out permission strategy can prevent data leaks and reduce the risk of errors caused by unauthorized changes. Consider the following best practices:

• Use Hierarchical Permissions: Set up a hierarchy where the parent company has oversight over its branches, while branch managers only access data relevant to their specific locations.
• Limit Cross-Company Visibility: Employees should only view records related to their assigned companies to maintain data integrity.
• Regularly Review Access Levels: Conduct periodic reviews of user access rights, especially when employees change roles or when the company structure changes.

5.3. Configuring User Access for Specific Scenarios

Odoo allows for customized access configurations to accommodate complex business structures:

1. Multi-Company Accountant Role:
   • If an accountant needs access to multiple companies, assign the Accountant role with access rights to each relevant entity. This enables cross-company reconciliation and consolidated financial reporting.
2. Sales and Purchase Permissions:
   • Sales teams can be restricted to specific companies, allowing them to handle leads and orders for their assigned business units without accessing unrelated company data.
3. Branch Manager Access:
   • Branch managers should have permissions to view and manage all branch-specific data, including inventory, local sales, and branch financials.

6. Tips for Optimizing Odoo’s Multi-Company Features

Implementing Odoo’s multi-company structure is only the first step. To fully leverage its capabilities, businesses should optimize their setup to streamline operations, reduce redundancies, and improve overall efficiency. This section provides actionable tips and strategies for making the most of Odoo’s multi-company features.

6.1. Shared Resource Management

One of the key advantages of Odoo’s multi-company functionality is the ability to share resources, such as product catalogs, suppliers, and contact lists, across different entities. Here’s how to set up shared resources effectively:

1. Enable Shared Contacts:
   • Go to the General Settings and enable the option for shared contacts across companies. This allows all subsidiaries to access a common contact database, reducing duplication and enhancing communication.
2. Centralize Product Catalogs:
   • Set up a centralized product catalog that all companies can access. This ensures uniformity in product offerings and pricing, making it easier to manage inventory and streamline sales.
3. Shared Services Management:
   • If multiple companies share services (e.g., IT support or logistics), set up internal service agreements and billing rules within Odoo. This helps track costs and allocate expenses accurately across the group.

6.2. Efficient Use of Inventory and Sales Modules

Managing inventory and sales across multiple companies can be complex. Using Odoo’s advanced modules can help simplify these processes and enhance operational efficiency.

1. Use Cross-Company Inventory Transfers:
   • Set up automated inventory transfers between branches to streamline stock management. For example, if one branch runs out of stock, an automated rule can trigger a transfer order from another location.
2. Centralized Sales and Procurement:
   • Configure one company as the central purchasing unit. This company handles all procurement and then distributes products to other companies, which helps negotiate better pricing and reduces administrative overhead.
3. Automated Price Lists and Discounts:
   • Implement centralized price lists and discount rules that apply across multiple companies to maintain consistency in pricing and promotional offers.

6.3. Streamlining Accounting and Compliance Processes

For businesses operating in multiple jurisdictions, managing compliance can be challenging. Odoo’s multi-company setup can help:

   • Use Odoo’s chart of accounts templates to standardize accounting practices across all companies, ensuring consistency in financial reporting.
2. Automate Tax Compliance:
