Why Odoo, Shopify & Klaviyo Work Better Together

Platform comparison: Odoo vs Shopify vs Klaviyo

Odoo, Shopify, and Klaviyo each serve a specialised role in the modern commerce stack. These platforms are not interchangeable; instead, they complement one another to deliver a full end-to-end commerce solution when integrated.

Shopify excels at managing front-end e-commerce functions, managing the online storefront, processing payments, and enabling smooth customer experiences.

Odoo is a powerful back-end ERP system that specialises in managing internal business processes such as inventory, order fulfilment, accounting, and customer relationship management (CRM).

Klaviyo automates personalised email/SMS campaigns that are personalised, timely, and driven by customer behaviour.

Here is the comparison table of the power trio:

How Shopify, Odoo & Klaviyo integration boosts efficiency

Integrating Shopify, Odoo, and Klaviyo creates a unified system that eliminates silos between sales, operations, and marketing, unlocking operational efficiency across the business.

Here’s how integration drives performance:

• Flexibility to scale: Integration allows your business to scale seamlessly, whether you’re adding new products, expanding to new markets, or shifting strategies, without reworking your tech stack.
• Real-time data sync: Orders, inventory, and customer data flow automatically across systems, so every team works with the most up-to-date information — no manual updates required.
• Departmental alignment: With shared data across Shopify (sales), Odoo (operations), and Klaviyo (marketing), teams stay aligned, reducing delays, miscommunication, and duplicated efforts.
• Reduced manual work: Automation handles everything from order syncing to email triggers, freeing up your team from repetitive tasks and reducing the risk of human error.

When integrated correctly, Odoo, Shopify, and Klaviyo provide a single source of truth that supports accurate operations, responsive marketing, and an exceptional customer experience — all of which are essential to scale efficiently.

Now let’s explore the critical workflows you can automate when these platforms are connected — and how they transform day-to-day business operations.

Critical Workflows You Can Automate Across Shopify, Odoo, and Klaviyo

Integrating Shopify, Odoo, and Klaviyo allows you to automate critical workflows, such as orders, customer data, inventory, and marketing, so your teams can work faster, make fewer errors, and create better experiences at scale.

Sync orders from Shopify to Odoo

Every new order placed on your Shopify store is automatically pushed to Odoo in real time, so your backend always stays in sync with your sales. Details like customer information, shipping method, product variants, and even gift cards are imported directly into Odoo, allowing for fast fulfilment, clean recordkeeping, and less manual effort. As the order progresses, Odoo can also push updates back to Shopify, marking orders as fulfilled, refunded, or cancelled.

Product & Inventory data aligned across systems

Product and stock data can sync between Shopify and Odoo in both directions, keeping your storefront and backend consistent. You can publish or unpublish products directly from Odoo and have changes instantly reflected on your Shopify store. Pricing, variants, inventory levels, and images all stay up to date. If you’re using multiple warehouses in Odoo, available stock can be consolidated and pushed to Shopify automatically, helping prevent overselling and customer service issues.

Sync customer profiles with Shopify data in Klaviyo

When integrated properly, Klaviyo automatically syncs key customer events and profile data from Shopify to create unified, real-time customer profiles. Every time someone views a product, starts checkout, or places an order, that activity is tracked and linked to a profile in Klaviyo. With this data, you can segment customers based on real engagement — not just static tags — and trigger campaigns that match how they actually shop.

Personalised campaigns based on real-time activity

Shopify and Klaviyo integration allows you to run personalised campaigns based on real-time activity. Whether it’s a welcome series, abandoned cart recovery, or post-purchase sequence, Klaviyo listens to what shoppers do and responds in real time. These automations are built to feel personal and timely, boosting engagement and conversions with almost no ongoing effort.

These automated workflows reduce human error, increase operational efficiency, and improve customer experience across channels. The next step is choosing how to connect Shopify, Odoo, and Klaviyo in a way that fits your business needs.

Which Integration Approaches Will You Use?

You can integrate Shopify, Odoo, and Klaviyo using either native integrations or custom-built solutions — the right approach depends on your business complexity, scale, and need for flexibility.

Shopify and Klaviyo: Native, built-in integration

Shopify and Klaviyo offer a direct, out-of-the-box integration — no third-party apps required. You can connect the two platforms in minutes and start syncing real-time customer data such as viewed products, checkout starts, and purchases. This integration powers Klaviyo’s dynamic customer profiles and triggers prebuilt flows like welcome series, cart recovery, and post-purchase follow-ups, making campaign automation fast and frictionless.

Shopify and Odoo: Pre-built connectors or a custom solution

While Shopify and Odoo don’t offer a native integration, there are two main paths to connect them effectively:

• Use a prebuilt connector: Prebuilt integration apps can sync core data like orders, products, inventory levels, and customer information between Shopify and Odoo. However, they’re often limited when it comes to handling custom pricing rules, multi-warehouse logic, or specialised workflows. You’ll also rely on the app developer for updates and issue resolution.
• Havi’s custom integration solution: For businesses with complex operations, unique processes, or plans to scale, Havi offers a fully customised Shopify and Odoo integration. As an official Odoo Partner in Australia, we design and maintain integrations tailored to your exact business logic — from two-way product sync to advanced fulfilment rules and payout reconciliation inside Odoo.

Choosing the right integration approach is the foundation of long-term operational success. In the next section, let’s see what this looks like in practice with a real-world use case from a high-volume business.

Use Case - Planning an Integrated Setup for a High-Volume Business

One of our clients, a fast-scaling consumer goods brand, is planning to process online orders through Shopify while managing in-house production and multi-warehouse fulfilment using Odoo. Our experts are advising them on the best-fit integration approach based on their operational needs and long-term scalability goals.

• Shopify powers e-commerce stores: The client plans to use Shopify to run high-converting, mobile-first storefronts designed for flash sales and product launches. Shopify will serve as the customer-facing platform for managing orders at scale.
• Odoo manages inventory, procurement, and invoicing: Odoo will handle inventory control, in-house production, procurement across multiple suppliers, and tax-compliant invoicing. The goal is to eliminate manual handovers and enable efficient fulfilment across warehouses.
• Klaviyo drives upsell and loyalty campaigns: Marketing campaigns will be driven by fulfilment and sales data from Odoo and Shopify. Klaviyo triggers post-purchase campaigns based on order value, product category, and fulfilment stage, turning first-time buyers into repeat customers.

By planning this three-platform setup, the client aims to reduce operational silos, automate key workflows, and deliver seamless customer experiences without significantly increasing headcount. Let’s look at how you can get started with a custom integration powered by Havi.
