If you sell on Allegro and run operations in ERPNext, the two systems live in separate worlds. Orders land in the Allegro seller panel, stock lives in ERPNext Bin and Warehouse records, and someone spends every morning rekeying orders, adjusting quantities across dozens of offers, and chasing why one listing oversold while another sat with hidden stock. ERPNext has no native concept of an Allegro offer, no awareness of Allegro's REST API, its checkout forms, or its Smart!/One Box delivery methods — so out of the box there is simply no bridge. Generic marketplace connectors tend to ignore Poland-specific realities like Allegro's OAuth flow, PLN settlements, commission and transaction fees, and the strict offer lifecycle Allegro enforces.

ECOSIRE builds the ERPNext Allegro Connector as a proper Frappe app, not a pile of loose scripts. It ships as an installable app with dedicated DocTypes — Allegro Settings (a Single DocType holding OAuth credentials, environment toggle, and sync switches), Allegro Offer (linked to ERPNext Item), Allegro Order Log, and Allegro Settlement — plus mapping tables that translate your catalog and price lists into Allegro's structures. Authentication uses Allegro's OAuth 2.0 authorization-code flow with automatic token refresh driven by a scheduler_events hook, so the connection stays alive without manual re-login.

Technically, the connector integrates through hooks.py document events and Frappe's background job queue. Incoming Allegro orders are pulled by a scheduled job, deduplicated against Allegro Order Log, and materialized as ERPNext Sales Order (and optionally Sales Invoice / Delivery Note) documents with customer, address, and Allegro checkout-form data mapped in. Inventory flows the other way: a Stock Ledger Entry / Bin on_update hook debounces and pushes available quantity back to the matching Allegro offer through whitelisted server methods, so stock stays consistent and oversells are prevented. Offer publishing and edits (title, description, price, parameters, images) are driven from the Allegro Offer DocType, and price changes on your chosen ERPNext Price List propagate to Allegro. Allegro delivery methods (Smart!, One Box, courier) are mapped to ERPNext shipping rules, and settlement/billing entries are imported into Allegro Settlement so marketplace commission and transaction fees reconcile cleanly against payouts. Role profiles and permission rules scope who can publish offers versus who can only view orders, and every API exchange is logged for auditability. The app targets Frappe/ERPNext v15 and v16.

Because this is build-to-order, ECOSIRE does not hand you a generic download and wish you luck. We start with a short scoping call to map your Allegro account structure, catalog size, offer templates, tax and fee handling, and fulfilment model. We then build the connector against your ERPNext instance, validate it on a staging bench with your real (sandbox) offers, run UAT with your team, and cut over to production with a rollback plan. Typical delivery is one working week from confirmed scope, and you receive the full source, a git repository handover, documentation, training, and a post-go-live support window.
