About this Product
Overselling is the fastest way to lose a marketplace account. One warehouse, many storefronts, and a few seconds of lag are all it takes to sell the same unit on Amazon, Shopify and your Odoo eCommerce site at once — then cancel, refund, and eat the metric damage. Marketplace Inventory Sync & Oversell Protection is a build-to-order Odoo module that ECOSIRE designs, develops, installs and supports specifically for your channel mix, so a single physical unit is committed to exactly one order across every connected sales channel.
This is not an off-the-shelf apps.odoo.com download. ECOSIRE builds it against your real warehouses, your live marketplace connectors and your fulfillment rules, then hands over clean, upgrade-safe source you own. The module treats Odoo's stock.quant free-to-sell quantity as the single source of truth. Computed available-to-promise fields (fields.Float with @api.depends on on-hand, reserved and inbound quantities) subtract per-channel safety-stock buffers before any number is pushed outward. When a channel confirms a sale, an atomic reservation writes to stock.move/stock.quant under database-level locking so two concurrent orders can never draw down the same unit — the second order hits the oversell lock and follows the back-order or out-of-stock policy you configured for that channel.
Under the hood it is idiomatic Odoo. New models extend product.product, stock.warehouse and the marketplace connector layer; automated actions and ir.cron scheduled jobs drive the near-real-time push loop and reconciliation sweeps; outbound writes to Amazon, eBay, Shopify, WooCommerce, Magento or your custom marketplace go over each platform's REST/GraphQL API, while inbound orders and other Odoo apps can read live availability over XML-RPC/JSON-RPC. Access is locked down with ir.model.access.csv plus record rules so channel operators only see and act on their own channels, and every sync event is journaled for audit. QWeb reports and OWL dashboards give your team a live oversell-risk view, buffer utilization per channel, and a full sync-failure log with one-click retry.
The result: no double sales, no manual spreadsheet reconciliation, no 2 a.m. panic when a listing goes viral. You keep selling aggressively — deep safety buffers on your best sellers, thin buffers on slow movers, hard oversell locks where the marketplace penalizes cancellations — with confidence that Odoo, not luck, is enforcing the rules. Compatible with Odoo 17, 18 and 19, Community or Enterprise. Typical delivery is one working week from kickoff, and it ships with configuration, documentation, training and a post-launch support window.

Who this is for
Multichannel seller plagued by overselling
You list the same SKUs on Amazon, eBay, Shopify and your own site from one shared warehouse. Sync lag means you regularly sell units you don't have, then cancel and refund — hurting your seller metrics and risking account suspension. You need a hard, Odoo-enforced guarantee that one unit is committed to exactly one order across every channel.
Operations / inventory manager
You own accuracy of stock across warehouses and channels and are tired of manual spreadsheet reconciliation and firefighting. You want per-channel safety buffers, clear allocation rules, an auditable sync journal, and alerts before a SKU tips into oversell — not after a customer complains.
eCommerce / marketplace manager scaling channels
You are adding new marketplaces and want to expose full stock aggressively on some channels while protecting inventory on penalty-heavy ones. You need configurable buffers, back-order policies and automatic delist/re-list per channel so growth doesn't multiply your cancellation rate.
Odoo administrator / IT lead
You maintain the Odoo instance and need a clean, upgrade-safe module — proper manifest, models, record-rule security and cron jobs — that integrates over each marketplace's API and exposes availability via XML-RPC/JSON-RPC, without brittle customizations that break at the next version upgrade.

Frequently Asked Questions about Marketplace Inventory Sync & Oversell Protection
How long does delivery take, and what does the build process look like?
Typical delivery is one working week from kickoff, depending on how many channels and warehouses are in scope and the complexity of your bundle/allocation rules. This is a build-to-order module — it is not an instant apps.odoo.com download. After purchase we run a short discovery call to map your channels, warehouses and policies, then design, build and test the module against your Odoo version (17, 18 or 19), install it on your server, migrate your stock baselines and run a supervised go-live cutover with you.
What support and updates are included after go-live?
Every build ships with a post-launch support and warranty window covering bug fixes, sync tuning and one Odoo point-release compatibility check. Because you receive the full source in a Git repository you own, there is no lock-in — any Odoo partner can maintain it. We also offer optional ongoing support and version-upgrade retainers if you'd like ECOSIRE to keep the module current as Odoo and your marketplace APIs evolve.
Which marketplaces and channels can it sync?
The module is built around your specific channel mix. Common targets include Amazon, eBay, Shopify, WooCommerce, Magento and Odoo's own eCommerce, plus custom or regional marketplaces exposed over a REST/GraphQL API. Each channel connects through its own API for outbound stock pushes and inbound order reservation. If a channel exposes an inventory API, we can integrate it — tell us your list during discovery.
How exactly does it prevent overselling when two orders arrive at the same time?
Availability is computed from Odoo's true free-to-sell quantity (on-hand minus reserved, adjusted for inbound and your per-channel buffer) using computed fields with @api.depends. When a channel confirms a sale, the reservation is written under database-level row locking on stock.quant, so two concurrent orders cannot draw down the same unit. The first order commits; the second hits the oversell lock and follows the back-order or hard out-of-stock policy you set for that channel.
Will it work with my multi-warehouse setup and product bundles/kits?
Yes. Multi-warehouse allocation rules let you aggregate stock across warehouses for a channel or dedicate a specific warehouse per marketplace or region. For bundles and kits, selling a bundle decrements every shared component's availability across all channels, and when any component hits its buffer the parent listing is automatically suppressed — preventing the classic oversell where two different bundles share one scarce part.
Does it require Odoo Enterprise, and is it upgrade-safe?
It runs on Odoo Community or Enterprise, versions 17, 18 and 19. The module is written as an idiomatic, upgrade-safe extension — a clean __manifest__.py, models that inherit rather than override core, security via ir.model.access.csv and record rules, and cron-driven sync — so it survives Odoo point upgrades. You own the source, so you're never blocked from upgrading or switching maintainers.
Can other systems read live availability from Odoo?
Yes. Available-to-promise quantities and sync status are exposed over Odoo's XML-RPC/JSON-RPC API and optional webhook/REST endpoints, so a 3PL, an external OMS, or another Odoo app can read live stock and trigger a re-sync programmatically — all governed by the same record-rule security so external callers only see what they're entitled to.
