Selling on Flipkart at any real volume means living in two systems at once. Orders land in the Flipkart Seller dashboard, your Stock, Sales Invoices, and GST records live in ERPNext, and the two never talk. Someone on your team re-keys every order, exports listing sheets by hand, watches FBF stock drift out of sync until a listing goes out of stock or oversells, and then spends the last week of every month matching Flipkart settlement payouts against commissions, shipping fees, and collection charges in a spreadsheet. ERPNext ships excellent order-to-cash and inventory accounting, but it has no native concept of a Flipkart marketplace, its order states, its fulfillment models, or its settlement files — so the integration work is exactly where ERPNext runs out of road.

ECOSIRE builds a proper Frappe app — installed on your bench as its own module, not a pile of manual customizations — that closes that gap. We model the marketplace with dedicated DocTypes (Flipkart Settings for API credentials and defaults, Flipkart Order, Flipkart Listing, and a Settlement Reconciliation record) and wire pulls and pushes through Frappe scheduler events and whitelisted methods that call the Flipkart Seller APIs. Incoming orders are fetched on a schedule, deduplicated against Flipkart's order and shipment IDs, and mapped into standard ERPNext Sales Orders and Sales Invoices with the correct customer, item, tax template, and warehouse. hooks.py doc events keep the flow bidirectional: when you approve a shipment or update stock in ERPNext, the connector pushes label/manifest and inventory updates back to Flipkart. Item mapping tolerates the reality that your ERPNext item codes rarely equal Flipkart FSNs/SKUs, so we maintain an explicit mapping layer rather than assuming a naming convention.

On the fulfillment side we handle both models. For self-ship, the app drives the label and manifest workflow — pulling shipping labels and generating the manifest so your packing team works from ERPNext. For FBF (Flipkart Fulfillment), inventory is Flipkart-held, so we sync available quantities against the correct ERPNext warehouse and reconcile so your stock ledger reflects what Flipkart actually holds, not a guess. Settlement is the piece most sellers ask for first: the connector ingests Flipkart's settlement reports, breaks each payout into its commission, shipping, collection, and adjustment components, and reconciles them against the matching Sales Invoices so your accounts show real net realization per order instead of a lump bank credit. Client scripts add the marketplace context to the ERPNext desk — status indicators, quick actions, and validation — and role profiles plus permission rules keep marketplace operators scoped to what they should see.

Because this is build-to-order, nothing is shipped blind. We start with a scoping call to confirm your fulfillment model (self-ship, FBF, or both), catalog size, tax setup, ERPNext version (v15 or v16), and which flows matter most to you. We then build against your actual account on a staging bench, run UAT with your real listings and orders, and only cut over to production once you sign off. Typical delivery is 2–4 weeks from confirmed scope. You receive the full source of your build, so you are never locked to us — though most sellers keep us on for a support window while volume ramps.
