Integrating E-Commerce with Odoo ERP
One source of truth for stock, orders, invoicing and customers, wired straight into your storefront by Hepek.
When your store and your ERP disagree, someone pays for it
Many teams run their storefront and their Odoo ERP as two separate worlds. Orders are re-keyed by hand, stock levels drift, oversold items get cancelled, and finance chases missing invoices at month-end. As you add channels, warehouses, currencies and tax rules across markets like the USA, Germany, Sweden and Qatar, the manual glue that once worked starts to crack. The result is slow fulfillment, unhappy customers and a finance team that never fully trusts the numbers. The problem is rarely Odoo or the storefront on its own, it is the missing, reliable connection between them.
A modern headless storefront that treats Odoo as the source of truth
Hepek builds a modern headless commerce storefront and wires it directly into Odoo ERP through Odoo's external API. Products, variants and pricing flow out of Odoo to the store, while orders, customers and stock movements flow back in. Odoo remains the single source of truth for inventory, accounting and fulfillment, and the storefront stays fast because it is decoupled from the back office. We tune each data flow to your reality, using real-time webhooks where overselling is a risk and scheduled batch syncs where near real-time is enough, so the integration matches how you actually trade across Europe, the Gulf, Bosnia and Herzegovina and beyond.
How it works
- 1
Map your Odoo data model
We start by mapping your Odoo product templates, variants, price lists, warehouses, tax positions and customer records to the storefront's catalog and checkout. Getting this model right upfront is what keeps the integration stable as your catalog and markets grow.
- 2
Connect through Odoo's external API
The storefront talks to Odoo over its external API, using XML-RPC or JSON-RPC to read and write records such as product.template, product.product, stock.quant, sale.order and account.move. A dedicated integration user and scoped access rights keep the connection secure and auditable.
- 3
Sync catalog and stock
Products, variants, images, prices and availability publish from Odoo to the storefront. Stock is kept in sync by reading quantities from Odoo and reflecting purchase receipts, manufacturing and manual adjustments, so what shoppers see matches what you can actually ship.
- 4
Push orders and customers into Odoo
When a shopper checks out, the order and customer are created in Odoo as a sales order, reserving stock and feeding the standard picking and delivery workflow. This gives your operations team one place to fulfill, invoice and support every order regardless of channel.
- 5
Choose real-time, batch or hybrid sync
For high-volume stores and multi-warehouse setups we use event-driven webhooks so stock and order updates propagate in seconds and overselling is minimized. For lower-volume or B2B-heavy stores we schedule batch syncs every few minutes, and we often combine both with periodic reconciliation for reliability.
- 6
Reconcile, monitor and harden
We add logging, retries and a scheduled reconciliation pass that catches any drift between the store and Odoo. Alerting and clear error handling mean issues surface early, long before they reach a customer or a month-end close.
Technology
Odoo Inventory
The backbone of stock accuracy. Warehouse quantities, reservations, receipts and adjustments in Odoo drive storefront availability, so customers only buy what you can fulfill across every location.
Odoo Sales
Every online order becomes a native Odoo sales order, flowing into the standard quotation, confirmation, picking and delivery pipeline your team already knows.
Odoo Accounting & Invoicing
Confirmed orders generate customer invoices and journal entries in Odoo, keeping revenue, taxes and reconciliation aligned with local requirements across markets like Germany, Switzerland and the Gulf.
Odoo Purchase
Replenishment and supplier receipts recorded in Odoo update available stock, so incoming inventory and reordering stay consistent with what the storefront advertises.
Odoo CRM
Storefront customers and their orders enrich Odoo's contact and CRM records, giving sales and support a unified view of each buyer's history for follow-up and retention.
Benefits
One source of truth
Odoo holds the authoritative record for stock, orders, invoicing and customers, so your storefront, warehouse and finance teams all work from the same numbers.
Fewer oversells and cancellations
Real-time or near real-time stock sync keeps availability honest, cutting the oversells and refunds that erode margin and customer trust.
No more manual re-keying
Orders, customers and invoices move automatically between the store and Odoo, freeing your team from copy-paste work and the errors that come with it.
Faster, cleaner fulfillment
Orders land in Odoo ready to pick, pack and ship through your existing workflows, shortening the path from checkout to doorstep.
Finance that reconciles itself
Invoices and journal entries flow into Odoo as orders confirm, making month-end close faster and reconciliation far less painful.
Built to scale across markets
Multi-warehouse, multi-currency and local tax handling in Odoo let you grow across the USA, Europe, Qatar and the wider Gulf without re-architecting your stack.
Frequently asked questions
How does an e-commerce store integrate with Odoo ERP?
An e-commerce store integrates with Odoo through Odoo's external API, using XML-RPC or JSON-RPC to read and write records such as products, stock quantities, sales orders and invoices. Hepek connects a modern headless commerce storefront to Odoo so the catalog and stock flow out to the store while orders and customers flow back into Odoo automatically.
Does Odoo integration keep inventory in sync in real time?
It can. Event-driven webhooks push stock and order updates in seconds, which minimizes overselling for high-volume and multi-warehouse stores. Lower-volume or B2B-heavy stores often use scheduled batch syncs every few minutes instead. Hepek chooses real-time, batch or a hybrid of both based on your order volume and risk of overselling.
Which Odoo modules are involved in an e-commerce integration?
The core modules are Inventory for stock, Sales for orders, and Accounting and Invoicing for finance. Purchase supports replenishment and supplier receipts, and CRM unifies customer records. Hepek maps your storefront directly onto these modules so Odoo stays the single source of truth.
Does the integration support product variants and multiple warehouses?
Yes. Odoo product templates and their variants map to the storefront catalog, and stock is tracked per warehouse location. This lets you sell configurable products and fulfill from multiple warehouses across regions such as Europe, the Gulf and Bosnia and Herzegovina without losing accuracy.
Can Odoo automatically generate invoices for online orders?
Yes. When an online order is confirmed as a sales order in Odoo, it can generate the corresponding customer invoice and accounting entries, keeping revenue, taxes and reconciliation consistent. This is especially useful for local compliance in markets like Germany, Switzerland and Sweden.
Will the integration keep working as Odoo evolves its API?
Yes, with maintenance. Odoo has signaled that the legacy XML-RPC endpoint will be retired in future releases, so Hepek builds integrations on supported API methods and keeps them updated as Odoo advances, protecting your storefront from breaking changes.
