Odoo's eCommerce app lets a business build a storefront directly on top of its own inventory, pricing, and accounting data, so a sale on the website updates stock and triggers invoicing without a separate sync step. That one-database advantage is real, as long as the sale happens on Odoo's own site. The moment a business also sells on Amazon, eBay, or another marketplace, that advantage stops, since those platforms have no built-in path into Odoo's data on their own.
A sale made directly on an Odoo-built storefront updates inventory and triggers an invoice the same way any other Odoo sale does, since it's all one system. A sale made on Amazon or eBay happens entirely outside Odoo, which means someone has to get that order into Odoo to update stock and books, and get current inventory levels back out to the marketplace so it doesn't oversell.
The same gap shows up for a business migrating onto Odoo's storefront from an existing separate site. Running both in parallel during the transition, keeping products, prices, and orders consistent across the old site and the new one, isn't something either platform handles without a bridge built specifically for that migration window.
When a business sells on Amazon, eBay, or another marketplace alongside Odoo's own storefront, we build the sync that pulls orders into Odoo and pushes current stock levels back out, so neither side oversells or runs on stale numbers.
If you're moving from an existing site onto Odoo's own storefront in phases, we build the temporary sync that keeps products, pricing, and orders consistent across both while the migration is still underway, not just once it's finished.
Tell us which other channels you sell through, and we'll scope out what's buildable to keep them all in sync.
Tell us which marketplace or separate site needs to stay in sync with Odoo's inventory and orders. We'll look at what's realistic to build against Odoo's own API. And if eCommerce isn't the piece of the business actually costing you time, we automate whatever part is.
Let's talk →Yes, Odoo's eCommerce app lets a business build and run its own online store, sharing the same database as Odoo's inventory, pricing, and accounting apps, so a web sale updates stock and triggers invoicing without a separate sync step.
Not natively. Marketplace sales happen entirely on the marketplace's own platform, so getting those orders into Odoo and keeping inventory accurate on both sides usually needs a custom integration rather than a built-in setting.
A version is included with the free Community edition, with additional themes, payment options, and features available on Odoo's paid Enterprise plans, the same split as most other Odoo apps.
Yes, for sales made directly through Odoo's own storefront, since it shares the same inventory data as the rest of Odoo. That automatic accuracy doesn't extend to other sales channels unless they're connected into Odoo separately.
