In this guide, you will learn how to set up multiple companies & users in Odoo 17 Accounting, configure company information, create branches, manage the Chart of Accounts, and prepare your ERP system for secure and scalable accounting operations.
Why Businesses Use Multiple Companies in Odoo 17 Accounting
Many growing organizations manage more than one company. Some operate different brands, while others maintain separate legal entities for taxation, regional operations, or business divisions. Without a centralized ERP solution, finance teams often struggle with duplicate data entry, inconsistent reporting, and disconnected accounting systems.
Fortunately, Odoo 17 Accounting solves these challenges by allowing businesses to manage multiple companies within a single ERP database. Each company maintains its own accounting records, tax settings, journals, fiscal positions, and financial reports. Meanwhile, authorized users can switch between companies without logging into multiple systems.
Moreover, Odoo provides complete data isolation between companies while allowing selected users to work across multiple organizations whenever necessary. Consequently, finance teams save time, reduce manual work, and improve reporting accuracy.
Benefits of Setting Up Multiple Companies & Users in Odoo 17 Accounting
Implementing multiple companies and users in Odoo 17 Accounting provides several operational and financial advantages for growing businesses.
Centralized ERP Management
Instead of maintaining separate ERP systems for each company, businesses can manage all operations from one centralized platform. Therefore, administrators spend less time maintaining software while improving overall productivity.
Better Financial Control
Each company maintains its own journals, taxes, fiscal positions, Chart of Accounts, and financial reports. As a result, accounting records remain accurate and fully separated.
Strong User Security
Odoo includes detailed user access controls that allow administrators to assign company-specific permissions. Consequently, employees only access the information required for their responsibilities.
Easy Business Expansion
As organizations continue growing, administrators can quickly create additional companies without changing the existing ERP environment. This flexibility makes Odoo an ideal solution for expanding businesses.
Multi-Currency and Localization Support
Businesses operating internationally can configure different currencies, languages, taxation rules, and accounting localizations for every company. Therefore, global financial management becomes significantly easier.
How to Set Up Multiple Companies & Users in Odoo 17 Accounting
Before configuring accounting data, you must first create or configure the company within the Odoo system. Proper company configuration establishes the foundation for accurate financial management, compliance, and business reporting.
When company information is configured correctly, Odoo generates reliable financial statements, including balance sheets, profit and loss reports, cash flow statements, tax reports, and other accounting documents. Furthermore, accurate company settings ensure that every accounting transaction belongs to the correct legal entity.
To begin configuring a company, navigate to:
Settings → Companies → Update Info
Alternatively, you can follow this navigation path:
Settings → Users & Companies → Companies
Here, Odoo displays every company configured within the database, including associated partners and branches. Administrators can easily switch between companies using the company selector available in the upper-right corner of the screen.
To create another company, simply click New.
Create a New Company in Odoo 17 Accounting
After selecting New, Odoo opens the Company form where administrators can configure all essential business information.
The General Information section allows you to define:
- Company Name
- Address
- Phone Number
- Mobile Number
- Email Address
- Tax ID
- Company ID
- Legal Entity Identifier (LEI)
- Website
- Company Currency
- Email Domain
- Company Color
Although these settings appear straightforward, they play an important role in accounting, reporting, invoicing, taxation, and company identification throughout the ERP system. Therefore, always verify this information before moving to the accounting configuration.
Configure Company Branches
Many organizations operate through regional offices or branch locations. Fortunately, Odoo allows administrators to organize these business units under a parent company.
Open the Branches tab.
Next, click Add a Line.
Then configure:
- Branch Name
- Parent Company
- Related Partner
- Branch Details
After saving the company, every branch becomes available for operational activities while remaining connected to its parent company. Consequently, businesses can manage distributed operations without creating unnecessary databases.
Configure the Chart of Accounts
Once the company has been created successfully, the next step involves configuring the Chart of Accounts, which serves as the backbone of financial management.
Inside the Company form, locate the Chart of Accounts section and click Review.
The Chart of Accounts page displays important accounting information, including:
- Account Code
- Account Name
- Account Type
- Allow Reconciliation
- Opening Debit
- Opening Credit
- Account Status
If additional ledger accounts are required, click New to create them.
A well-organized Chart of Accounts improves bookkeeping accuracy, financial reporting, tax compliance, and auditing. Furthermore, it allows businesses to generate reliable reports for management and statutory requirements. Therefore, configuring the Chart of Accounts carefully is one of the most important steps in setting up multiple companies and users in Odoo 17 Accounting.
Configure Users in Odoo 17 Accounting
After configuring the company, the next step in how to set up multiple companies and users in Odoo 17 Accounting is creating users and assigning the correct permissions. User management plays a vital role in protecting financial data and ensuring employees access only the information they need for their daily responsibilities.
Odoo 17 includes a comprehensive user management system that enables administrators to create users, assign them to one or multiple companies, configure access rights, and manage authentication settings from a single location. Consequently, businesses maintain stronger security while improving collaboration across departments.
Navigate to:
Settings → Users & Companies → Users
The Users page displays important information such as:
- Name
- Login
- Language
- Company
- Latest Authentication
- Status
To add a new employee, click New.
Create a New User in Odoo 17 Accounting
The User form allows administrators to configure the employee’s profile and company access.
Enter the following information:
- User Name
- Email Address
- Profile Image
- Assigned Company
- Allowed Companies
If an employee works across multiple companies, simply assign all the relevant companies. As a result, the user can switch between authorized companies without logging into different ERP databases.
This flexibility makes Odoo 17 Accounting an excellent solution for finance teams, consultants, auditors, and senior managers who oversee multiple business entities.
Configure User Access Rights
One of the strongest features of Odoo is its role-based security model. Instead of providing unrestricted access, administrators can define exactly what every employee can view, create, edit, approve, or delete.
Open the Access Rights tab.
Here, you can configure permissions for several applications, including:
- Sales
- CRM
- Purchase
- Inventory
- Manufacturing
- Accounting
- Website
- Marketing
- Human Resources
- Project
- Timesheets
- Administration
Since each department performs different responsibilities, assigning appropriate permissions significantly improves data security.
Furthermore, limiting unnecessary access reduces accidental errors and protects confidential business information.
Configure Accounting Access Rights
When configuring multiple companies and users in Odoo 17 Accounting, accounting permissions deserve special attention because financial information remains highly sensitive.
Odoo provides multiple accounting permission levels, including:
- Billing
- Read-Only
- Bookkeeper
- Accountant
- Consolidation User
Each permission level grants different capabilities.
For example, a Billing user can create customer invoices but cannot perform advanced accounting operations. A Bookkeeper can record accounting transactions and reconcile payments. An Accountant gains access to journals, financial reports, tax configuration, and closing entries. Meanwhile, a Consolidation User can analyze financial data across multiple companies for consolidated reporting.
Therefore, assigning the correct accounting role improves security while ensuring employees perform their tasks efficiently.
Configure User Preferences
The Preferences tab allows administrators to personalize the working environment for every employee.
Here, you can configure:
- Preferred Language
- Time Zone
- Email Signature
- Notifications
- Digital Signature
- Default Warehouse
- VoIP Settings
These settings enhance the user experience while ensuring each employee works with the correct regional configuration. Additionally, configuring the appropriate language and time zone improves communication across globally distributed teams.
Configure OAuth Authentication
Many organizations integrate their authentication systems with external identity providers.
The OAuth tab includes options for:
- OAuth Provider
- OAuth User ID
- OAuth Access Token
By enabling OAuth authentication, businesses simplify user login while improving overall account security. Moreover, employees can access Odoo using trusted authentication services instead of managing separate credentials.
Enable Two-Factor Authentication
Protecting financial information should always remain a top priority.
Odoo 17 includes Two-Factor Authentication (2FA) under the Account Security tab.
After enabling 2FA, users must verify their identity using a second authentication method in addition to their password. Consequently, unauthorized users cannot easily access accounting records even if passwords become compromised.
For finance managers, accountants, auditors, and ERP administrators, enabling Two-Factor Authentication is considered a best practice.
Synchronize Calendars
The Calendar tab allows users to connect external calendar services directly with Odoo.
Supported integrations include:
- Google Calendar
- Microsoft Outlook Calendar
Once configured, employees can synchronize meetings, appointments, reminders, and schedules across their preferred calendar applications. As a result, collaboration becomes more efficient throughout the organization.
Best Practices for Managing Multiple Companies and Users in Odoo 17 Accounting
Although Odoo simplifies multi-company management, following proven implementation practices helps businesses achieve better long-term results.
First, configure each legal entity separately with its own Chart of Accounts, tax rules, journals, fiscal positions, and accounting settings. Next, assign users only to the companies required for their daily responsibilities. Likewise, review user permissions regularly to remove unnecessary access whenever roles change.
Furthermore, enable Two-Factor Authentication for finance users and administrators to strengthen account security. In addition, maintain separate accounting policies for each legal entity while keeping company master data updated. Businesses operating internationally should also configure the appropriate currencies, fiscal localizations, and tax structures during implementation.
Finally, schedule routine database backups and test configuration changes in a staging environment before applying them to the production system. Following these best practices helps maintain accurate accounting records, improve compliance, and reduce operational risks.
