Why the right Odoo stack determines success in e-commerce
The German e-commerce market is one of the toughest in Europe. Customers expect unbeatable prices, seamless processes, lightning-fast deliveries, and excellent service. A great online store alone isn't enough to stand out anymore. The key is perfect coordination of all back-office processes: from inventory and purchasing to customer communication and accounting – everything needs to work together smoothly.
Odoo is now considered the most flexible platform for e-commerce, adaptable to any business model. But which modules are truly essential for online retailers in Germany? As an experienced Odoo partner for e-commerce solutions, we present our carefully selected top 7 most important Odoo modules that will be a must-have for professional shop operators in 2025.

The Essential Foundation: The Top 7 Odoo Apps for E-Commerce Success
1. Odoo E-Commerce & Website
The foundation for your online store:
These two modules are essential! With the user-friendly drag-and-drop editor in the website module, you can create modern, responsive shop pages without any coding skills. The e-commerce module includes a product catalog, shopping cart, checkout, and flexible payment options—all seamlessly integrated. Unlike many external platforms like Shopify, you maintain control over your data and can customize the shopping experience.
2. Maildesk: Email Management at a New Level
Customer Communication as a Competitive Advantage:
Every support request matters. With the MailDesk module, you can integrate all customer emails directly into Odoo—whether they come from Outlook, Gmail, or other systems. Your team sees every message in context with the corresponding customer profile, order, and previous interactions. This speeds up handling, increases transparency, and creates a real service advantage.
Advantage: Faster responses, less duplication of work, and a central, GDPR-compliant communication archive.
3. Inventory
Perfect logistics, even with high order volumes:
Manage your inventory across multiple locations in real-time with the Inventory Module. Enjoy automatic reordering, pick lists, shipping labels, and direct connections to carriers like DHL, DPD, and GLS for a seamless fulfillment process. Minimize errors and overselling with comprehensive stock management.
4. Purchase
Automated Procurement Management:
The Purchase Module streamlines your shopping process from order requests to invoice checks. Compare prices, manage suppliers, and automate minimum stock levels to keep bestsellers in stock without overloading your inventory. Stay on top of delivery times and costs while boosting your margins.
5. CRM (Customer Relationship Management)
More than just B2B – CRM is the engine for customer retention:
Segment your customers, run personalized campaigns, and manage large client requests all in one place. Our smart CRM module helps turn one-time buyers into loyal customers with targeted communication, follow-ups, and integrated marketing actions.
6. Accounting
Legally compliant GoBD accounting directly in Odoo:
For German e-commerce businesses, transparent and audit-proof accounting is essential. The Odoo accounting module is perfectly tailored to meet GoBD requirements and German tax laws. Automate invoicing, payment tracking, and DATEV exports. Your accountant will appreciate it!
7. Marketing Automation
Targeted Customer Retention & Revenue Growth on Autopilot:
With Odoo Marketing Automation, you can manage smart email campaigns, personalized offers, and reminders for abandoned carts – all fully automated. Examples:
- Thank you for your purchase email with discount code
- Reactivation campaigns for inactive customers
- Automated birthday wishes or reminders for sold-out favorites
Make your shop memorable – so your customers keep coming back.
