Walmart Marketplace Seller Connector

The problem

Sellers diversifying off a single marketplace add a Walmart seller account and immediately inherit a second operations process. Zoho Inventory has no native Walmart channel, so orders are downloaded as CSV and imported, or typed in. Available stock is maintained twice — once in Zoho, once in Seller Center — which means either the safety buffer is set so high that sales are lost, or it is set realistically and the account eventually takes an oversell and the cancellation rate metric suffers.

Finance has the harder half. Walmart settles net of referral fees, shipping adjustments, refunds and other deductions, so the amount that lands in the bank never matches the sum of order totals. Reconciling that in Zoho Books by hand, per settlement period, is slow and it is where errors hide.

What ECOSIRE builds

ECOSIRE builds a connector between your Walmart Marketplace seller account and your Zoho org, using the Walmart Marketplace APIs and delivered as Zoho Flow orchestration with Deluge custom functions, plus a Zoho Creator control app where you need a screen to manage exceptions. It is built to order against your catalogue, your fulfilment model and your chart of accounts — there is no ready-made download.

Order ingestion

New Walmart orders are pulled on a schedule and created in Zoho Inventory as Sales Orders, with the Walmart purchase order number and customer order id stored in custom fields so every record traces back to Seller Center. Line items map to your Zoho items by SKU using a mapping table that we build and that you can maintain. Shipping method, requested ship-by date and buyer shipping address carry across so pick and pack works from Zoho.

Cancellations and buyer-initiated changes are picked up and applied to the Zoho Sales Order rather than left to be discovered at packing.

Fulfilment and shipping

When a shipment is recorded in Zoho Inventory, the connector posts the shipping confirmation back to Walmart with carrier, tracking number and ship date, so the order is acknowledged inside the marketplace's expected window without anyone opening Seller Center. Partial shipments and multi-package shipments are handled explicitly rather than collapsed into one event.

Inventory and pricing

Available quantity from your chosen Zoho Inventory warehouses is pushed to Walmart on a schedule, with per-SKU buffer rules so you can hold back stock on lines you also sell elsewhere. Where you want price control from Zoho, price updates push to Walmart from the Zoho item record, with guard rails that refuse a push outside a configured tolerance — a mistyped price should fail loudly, not go live.

For multi-warehouse sellers we support fulfilment-location logic so quantity reflects the locations that actually serve Walmart orders.

Settlement and accounting

This is the part most sellers commission the build for. The connector retrieves Walmart settlement reports and creates the corresponding records in Zoho Books: sales invoices or a summarised sales entry per your accountant's preference, referral and fulfilment fees posted to the expense accounts you nominate, refunds and adjustments posted against the original transaction, and a bank deposit line matching the actual payout so the settlement reconciles against your bank feed rather than approximately.

Sales tax handling follows your Zoho Books tax configuration and your marketplace-facilitator position, which we confirm with you and your accountant during scoping rather than assume.

Exceptions

Unmapped SKUs, failed pushes, rejected shipping confirmations and settlement lines that do not match are surfaced in a queue — a Zoho Creator app or a Zoho Inventory custom view, depending on your scope — with the raw payload attached so the cause is visible. Nothing fails silently.

Who this is for

US and Canada sellers running Zoho Inventory and Zoho Books who have an active Walmart Marketplace seller account and enough order volume that manual CSV handling has become the bottleneck. It fits both seller-fulfilled operations and sellers using Walmart's fulfilment programme, though the fulfilment flows differ and are scoped separately.

It is equally relevant to sellers already running an Amazon channel in Zoho who want Walmart handled to the same standard rather than as an exception.

How delivery works

1. Scoping call. We review your Walmart seller account setup and API access, your Zoho Inventory warehouse and item structure, your SKU conventions against Walmart item ids, your fulfilment model, and how your accountant wants marketplace revenue, fees and taxes represented in Zoho Books.

2. Fixed quote. You receive a written scope covering each flow — orders, cancellations, shipping confirmation, inventory, price, settlement — the sync frequency, the exception handling, and a fixed price. Anything outside it is quoted before work begins.

3. Build. Typical lead time is one working week from acceptance. We build against your Walmart sandbox or a limited live scope, and against a non-production Zoho Books organisation where you have one.

4. Install in test, then production. We run in test with real order shapes from your account, then enable production flows in stages: orders and shipping confirmation first so operations benefit early, inventory push next, settlement posting last once your accountant has approved a full settlement period end to end. Inventory push is the flow we deliberately enable last among the operational ones, because a wrong quantity is public.

5. Support. A support window follows go-live for defect fixes, SKU mapping corrections and schedule tuning. Walmart changes its APIs periodically; ongoing maintenance beyond the included window is available as a separate arrangement, and we tell you that up front rather than after the first breaking change.

Honest limits

This is a build service with a lead time. There is no instant download and no free trial, and we are not a marketplace-affiliated or certified partner — the connector uses Walmart's publicly documented seller APIs with credentials you generate in your own seller account. Rate limits, report availability and API behaviour are set by the marketplace, and we design the sync schedule around them rather than promising real-time updates we cannot guarantee.
