Allegro Marketplace Connector (Poland/CEE)

If Allegro drives your volume in Poland and across CEE, but your stock, prices and orders still live in a separate seller panel, you are paying for that gap every day — oversells, stale prices, manual copy-paste of orders, and missed shipping SLAs that dent your Super Sprzedawca standing. The Allegro Marketplace Connector closes that gap by making Odoo the single source of truth for your Allegro catalog, offers, orders, inventory and fulfillment.

This is not an off-the-shelf download from apps.odoo.com. It is a build-to-order module that ECOSIRE designs, builds, installs, configures against your real Allegro seller account and supports. We scope your categories, parameters, shipping methods and pricing rules first, then deliver a connector that fits how you actually sell — not a generic template you have to bend around.

What it does, in Odoo terms

The connector ships as a proper Odoo addon (__manifest__.py declaring dependencies on sale_management, stock, product and delivery). It introduces dedicated models — allegro.account, allegro.offer, allegro.category.mapping, allegro.parameter.mapping and allegro.order — extending product.template, product.product, sale.order and stock.quant where the marketplace data belongs. Authentication uses Allegro's official REST API with OAuth2 (device flow for onboarding, refresh-token rotation for unattended sync), so we never scrape the seller panel or rely on brittle CSV exports.

Two-way sync runs on Odoo scheduled actions (ir.cron) plus automated actions on write, with a manual "Sync now" button on each account. Every field that matters — price, quantity, offer status, order state — reconciles on a cadence you choose, and a per-record sync log tells you exactly what happened and why if Allegro rejects an offer.

Built for the way Allegro actually works

Allegro is not "just another marketplace." Category-specific required parameters, offer vs. product-catalog listings, the EAN/GTIN product-matching flow, One Fulfillment by Allegro, Allegro One Box and Smart! delivery, and złoty (PLN) VAT invoicing all have to be modeled correctly or listings get rejected. We build the category and parameter mapping layer so your Odoo product attributes map cleanly to Allegro's taxonomy, and we wire Allegro shipping so labels and tracking flow back to the customer without you touching the seller panel.

Delivered on Odoo 17, 18 or 19, Community or Enterprise, with security done right — ir.model.access.csv for every new model plus record rules so a multi-company or multi-account setup keeps each seller account's data isolated. Views are built in standard Odoo XML with OWL components where interactivity helps, and order/invoice documents use QWeb so your Allegro sales look like the rest of your Odoo paperwork.
