Setting Up Your Odoo 18 for eCommerce and PoS

Before diving into integration, ensure your Odoo 18 environment is properly set up.

Install Essential Modules

Navigate to Apps, then install these modules:

• Website
• eCommerce
• Point of Sale
• Inventory
• Accounting

These are the building blocks of the integration. Each module plays a crucial role.

Configure Company Settings

Go to Settings > Companies > Your Company:

• Enable multi-warehouses (if needed)
• Set currency and tax options
• Add your company logo and address

Create and Sync Products in Odoo 18

Add Products to Your Inventory

Head to Inventory > Products > Create:

Under “Sales”, check:

• Available in PoS
• Published on Website

Now the product is visible both online and in-store. This is the core of Odoo eCommerce integration.

Manage Product Variants

From the product page, add attributes like color or size. Odoo will create variants for each combination.

This lets customers choose variants on your website and also allows cashiers to select them in-store.

Build Your Online Store with Odoo Website Builder

Launch the Website App

Click Website > Go to Website. Then choose the “Shop” template. You’ll land in a drag-and-drop editor.

Add Products to the Shop Page

Use the “Products” block from the sidebar. Drag and drop it onto your page. Configure the layout: grid, list, or carousel.

Customize the Look and Feel

• Upload your logo

• Add banners, testimonials, and sections

These design elements boost trust and brand recognition.

Configure Your Point of Sale

Odoo PoS is powerful and works offline. Let’s configure it to work with your website store.

Create a New Session

• Click Create
• Name your session (e.g., Mall Outlet)
• Choose your store location
• Select payment methods (cash, card, eWallet)

Assign Products to PoS

Use product categories and enable real-time inventory sync. This ensures your PoS session reflects website stock.

Link eCommerce and PoS with Inventory

Use a Single Warehouse

Go to Inventory > Configuration > Warehouses:

• Make sure both eCommerce and PoS use the same warehouse
• This simplifies stock updates and reporting
