Odoo Pos Customization and Permissions

Project Overview – Advanced Odoo POS with Granular User Permissions

What is it?

This project is an advanced Odoo Point of Sale (POS) system, extended with a powerful, custom-built Permission Management Engine. The core Odoo POS features have been enhanced to allow administrators to define, with extreme precision, what each cashier, manager, or employee can see and do within the POS interface.

It is not just a POS system; it is a secure, controlled, and role-based sales environment. All customizations are packaged as modular Odoo add-ons.

Why is it valuable for a buyer?

Enhanced Security & Control: Prevents unauthorized actions (e.g., applying discounts, editing prices, deleting orders) by restricting them based on user roles.

Minimizes Revenue Leakage: By limiting access to sensitive functions, the risk of internal fraud or costly errors is drastically reduced.

Operational Efficiency: A cleaner POS interface, showing only relevant buttons to each user, leads to faster training and fewer mistakes.

Complete Audit Trail: Every transaction and action can be tied back to a specific user, providing full accountability.

Off-the-Shelf & Ready to Deploy: A full-featured system that is far more advanced than Odoo’s standard POS, saving months of development.

Core Features (What the Buyer Gets)

This project consists of a suite of custom Odoo modules providing a comprehensive solution:

1. Granular Permission Management Engine

Role-Based Access Control (RBAC): Define permissions based on users, employees, or custom security groups.

Per-Employee Configuration: Set permissions individually for each employee via a dedicated "POS Access" tab on their profile.

Shop/Branch Assignment: Restrict which POS configurations (shops, counters) a user can access.

2. Full Control Over POS Actions

This module allows toggling access to each critical action:

Payments: Restrict access to the payment screen.

Pricing: Control who can edit product prices.

Discounts: Restrict the ability to apply discounts.

Order Lines: Control deletion of individual lines or entire orders.

Customer Selection: Restrict who can change the customer on an order.

Refunds: Define who is authorized to process returns.

Session Management: Control who can open or close a POS session.

Numpad & Quantity: Restrict manual quantity entry.

3. UI/UX Customization

Button Visibility: Hide or disable restricted buttons for unauthorized users, providing a clean and intuitive interface.

Custom Screens & Buttons: Includes the ability to create and integrate additional, fully customized screens or buttons for specific business needs (e.g., a "Clear All Orders" button).

PIN/Badge ID Login: Secure POS access using employee PIN or badge ID for accountability and security.

🔧 Permissions & Customization Capabilities

The heart of the project is its powerful permission system, structured on three key Odoo security concepts:

Security Groups (Roles): Create groups like Manager, Senior Cashier, Junior Cashier, and assign specific permissions to each group.

Record Rules: Implement data-level security, e.g., ensuring a cashier sees only their own orders, or hiding supplier/vendor data from POS screens.

Access Rights: Configure field-level access for sensitive data like product costs or profit margins.
