If you sell on Shopee across Southeast Asia or LATAM, your operational truth lives in the Shopee Seller Center while your accounting, stock, and fulfilment live in ERPNext — and the two drift apart every hour. ERPNext core has no concept of a Shopee order, a Shopee SKU mapping, or a Shopee escrow settlement, so teams end up re-keying orders into Sales Order, manually decrementing Bin quantities, and reconciling payouts in spreadsheets. Overselling, wrong stock, and unexplained settlement gaps are the direct result. This is exactly where ERPNext native runs out of road: it is a superb backend, but it does not speak the Shopee Open API.

ECOSIRE builds the ERPNext Shopee Connector as a proper Frappe app — a versioned module with its own DocTypes (for example Shopee Settings, Shopee Shop, Shopee Item Map, and Shopee Order Log), not a pile of loose scripts. Order ingestion runs on scheduler_events that poll the Shopee Open API, verify the HMAC signature, and create or update Sales Order / Delivery Note records idempotently, keyed on the Shopee order SN so retries never duplicate. Inventory and price flow two ways: ERPNext Stock Ledger Entry changes are picked up via hooks.py doc events and pushed to Shopee stock, while Shopee-side edits are reconciled back on the next scheduler tick, all mediated by your SKU-to-variation mapping so parent/variation items line up correctly.

On the fulfilment side we wire the Shopee shipping workflow into ERPNext — booking the shipping document, retrieving the airway-bill / label, and stamping the tracking number back onto the Delivery Note so your warehouse prints and ships without leaving ERPNext. Settlement reconciliation pulls Shopee's escrow and payout detail and lands it as structured records you can match against invoices, exposing commission, service fees, and adjustments instead of a lump payout. Every integration point is guarded by ERPNext permissions and role profiles, exposes its actions through whitelisted methods over the Frappe REST API, and is observable through the Shopee Order Log and Frappe's Error Log. Client Scripts add the operator-facing niceties (a "Sync now" button, status indicators) on the relevant forms.

Because this is build-to-order, nothing is a black box you download blind. We start from a short scoping call, confirm which Shopee regions and shops you run, which item and warehouse structure you use, and how you want settlements posted. We build against Frappe/ERPNext v15 and v16, test on a staging bench with your real catalogue shape, run UAT with you, and only then install on production with a rollback plan. Typical delivery is one working week from confirmed scope, and you receive the full source and git repository so the app is yours to keep and extend.
