In today fast paced business environment, having access to your business tools on the go is essential. Odoo is a powerful ERP system used by companies worldwide, but accessing it conveniently on mobile has been a challenge.

To solve this, we developed a mobile application for Odoo using Flutter, designed to support both Odoo Enterprise and Community editions. This app makes it easier for users to log in, manage workflows, and access essential business modules anywhere, anytime.

The app is fully compatible with older to newer Odoo versions, including Odoo 17, 18, and 19, ensuring a smooth experience across all setups.

Backend Security and Mobile Authentication Features To ensure controlled and secure mobile access, this module introduces additional backend level authentication management within Odoo. A new configuration option named Allow Mobile Login is added directly to the Odoo user form. This setting gives administrators full control over which users are permitted to access Odoo through the mobile application.

By default, mobile access can be restricted at the user level. Only users for whom the Allow Mobile Login checkbox is explicitly enabled are permitted to authenticate from the mobile application. This approach ensures that mobile access is not automatically granted to all users and remains fully under administrative control, aligning with standard enterprise security practices.

On the backend side, the module extends Odoo authentication flow by introducing a dedicated mobile authentication method. This method validates user credentials in a controlled manner while also checking the mobile access permission defined on the user record. If mobile login is disabled for a user, authentication requests originating from the mobile application are rejected, even if the username and password are correct. This ensures that backend rules are always enforced consistently.

The authentication logic is implemented entirely within the Odoo backend, without modifying core files. It integrates cleanly with Odoo existing user and security model, making it compatible with all supported Odoo versions. The mobile application communicates securely with Odoo, while the final authorization decision is handled exclusively by the server side logic.

This design allows organizations to safely deploy a mobile WebView application without compromising backend security or user access policies. Administrators can easily enable or revoke mobile access at any time, without affecting web access or requiring changes to user roles, permissions, or groups.

By combining user level mobile access control with a dedicated backend authentication mechanism, the module provides a secure, scalable, and enterprise ready solution for managing mobile logins in Odoo. The implementation follows Odoo best practices and is suitable for both Community and Enterprise editions across all versions.

Universal Flutter Based Mobile WebView Application for Odoo (All Versions Supported)

Managing Odoo on mobile often becomes challenging when different versions, customizations, or deployments are involved. This Flutter based mobile application is designed to solve that problem by providing a single, universal mobile solution that works seamlessly with all versions of Odoo. Built using modern Flutter technology and WebView support, the application allows users to access their existing Odoo web interface directly from Android and iOS devices without any version dependency.

The application acts as a secure mobile wrapper around the Odoo web client, ensuring that businesses can continue using their current Odoo setup without additional configuration, migration, or module compatibility concerns. Since the app relies on WebView, it automatically supports Community and Enterprise editions, on premise, Odoo.sh, and cloud deployments, making it a future proof solution for organizations running multiple Odoo environments.

Developed with Flutter, the application delivers a consistent user experience across platforms while maintaining native performance. Users can log in using their existing Odoo credentials and instantly access dashboards, documents, workflows, and business operations in real time. Any updates or changes made in the Odoo backend are immediately reflected in the mobile app, eliminating the need for separate mobile customizations.

This solution is ideal for companies looking for a lightweight yet powerful mobile interface for Odoo. It reduces maintenance overhead, avoids version lock in, and ensures long term compatibility as new Odoo versions are released. Whether for sales teams, managers, accountants, or field staff, the application enables full access to Odoo anytime and anywhere through a single mobile app.

The Flutter based WebView architecture also ensures faster development cycles, easier upgrades, and improved stability compared to traditional native apps. By using the official Odoo web interface, users benefit from the same features, security updates, and custom modules already implemented in their system, without duplication or extra development effort.

This universal mobile application is a practical and scalable approach for businesses that want reliable mobile access to Odoo across all versions while keeping implementation simple, cost effective, and future ready.
