Walmart Supplier One Explained: A Complete Portal Guide for Suppliers

Supplier One is Walmart's supplier portal, launched in 2024 to consolidate the day-to-day tasks suppliers used to scatter across multiple Retail Link apps. It is where U.S. suppliers set up items, manage purchase orders, handle payments and deductions, configure ship points, and monitor performance, all from one dashboard instead of opening a separate window for each function.

Supplier One does not replace Retail Link. It sits alongside it as part of Walmart's three-tool supplier ecosystem, absorbing specific workflows while Retail Link and Scintilla handle others. Understanding what lives where is the difference between navigating Walmart efficiently and hunting through the wrong system for a report that moved.

What Is Walmart Supplier One?

Supplier One is an online portal that consolidates supplier-facing functions into a single, unified interface. Walmart built it on a hub-and-spoke model: one dashboard that connects to and integrates with the apps and portals suppliers need, without requiring any code or custom setup on the supplier's end.

It is available to all continental U.S. suppliers and covers both Owned (warehouse) and Drop Ship Vendor (DSV) businesses. Canadian suppliers have limited functionality. Supplier One is designed for laptops and desktops, not tablets or phones.

The purpose is straightforward: reduce the number of systems a supplier has to touch to run daily operations. Before Supplier One, item setup lived in Item 360, ship points lived in Aspen, and PO management, payments, and performance data were spread across separate Retail Link apps. Supplier One pulls these into one place.

Supplier One vs Retail Link vs Scintilla

The most common source of confusion is how Supplier One relates to Walmart's other two supplier tools. Suppliers do not choose between them. They use all three, and each answers a different question.

Retail Link tells you whether you are meeting Walmart's operational requirements. Supplier One is where you take daily action. Scintilla (formerly Luminate) is the analytics layer for understanding customer behavior.

A key point for finance teams: Supplier One is where day-to-day payment accuracy lives, but it does not replace APIS or APDP. Disputes still flow through the Accounts Payable Dispute Portal in Retail Link.

What Supplier One Replaced

Supplier One has absorbed several standalone Retail Link apps, and Walmart has made some of these transitions mandatory.

• Item 360: as of September 18, 2024, item and inventory workflows are accessed exclusively through Supplier One. Item 360 automatically redirects U.S. suppliers to Supplier One

• Aspen: ship point management moved into Supplier One

• NOVA functions: order and PO tracking now mirror much of what NOVA did in Retail Link

Walmart has said apps like NOVA remain functional "as of now," which signals that more consolidation is likely on the horizon. The direction is clear: Supplier One is becoming the central operational hub.

How to Access Supplier One

Walmart uses single sign-on, so Retail Link credentials also grant access to Supplier One.

Three ways in:

• Go directly to https://supplierone.wal-mart.com and sign in with your Retail Link email ID and password
• From Retail Link, go to Apps, search "Supplier One" in the filter field, and open it
• Bookmark the direct URL for fastest access

If you are denied access, the fix is a permissions adjustment from your company's Retail Link administrator, not a Walmart support ticket.

Navigating the Supplier One Dashboard

Signing in lands you on the Home page, which is built for at-a-glance priority setting. Expand the left navigation menu by clicking the lines next to the Walmart logo in the top left.

What the Home page shows:

• Order summary: a snapshot of open orders

• Returns overview: units returned and return trends

• Scintilla access: a direct link to omnichannel data

• Top tasks: quick access to the actions that need attention

• Content quality: status and enhancement prompts

• Announcements carousel plus links to APIs, Walmart Connect, brand registration, training, FAQs, and Retail Link

The design goal is to let suppliers see what needs action without opening multiple windows.

The Core Supplier One Tabs

The left navigation is where the daily work happens. Each tab consolidates a function that used to require a separate app or portal.

Orders

Track, review, and manage purchase orders by status, including new POs, closed orders, and past due. Suppliers can also create a PO request. This section tracks fill rates and shortages, mirroring much of what NOVA handled in Retail Link.

Items and Inventory

The central hub for catalog management, item setup, item maintenance, and brand registration. This tab replaced Item 360 as the exclusive path for U.S. supplier item workflows, with an enhanced interface over the old catalog, setup, maintenance, and submissions manager.

Ship Point Management

Set up and manage shipping locations, lead times, calendars, and closures across your supply chain network. Collect shippers must create ship points here before they can route orders. This function replaced Aspen.

Payments and Deductions

Monitor payments, view past purchase orders and the amount paid for each, and access financial records including deductions and chargebacks. This is where finance teams focus for day-to-day payment accuracy, and where you connect through to the APDP for disputes.

Reports

Consolidated reporting in one place, including the Unpaid Invoice Details report and other financial and operational reports suppliers previously pulled from scattered locations.

Performance

View your scorecard, OTIF trends and charges, and Claims and Returns scorecard. This is where onboarding-era compliance preparation becomes ongoing performance monitoring.

Managing Your Supplier Profile in Supplier One

Beyond daily operations, Supplier One houses your complete supplier profile. Access it by clicking Account and selecting Supplier Profile, then use Switch Vendor to select the supplier number you want to manage.

The profile areas:

• Registration: business verification, tax information, eligibility, and agreements

• My Team: contacts and business certifications, including U.S. Small Business Program certifications

• Sourcing Profile: company capabilities, business performance, and customer base

• Product & Insurance: product proposals and insurance certifications

• Agreements: view and sign business agreements

• Payment: banking information, updatable only by Retail Link Administrators

• Shipping and Warehouses: ASN/DEX selection, transportation ship points, and warehouse details

• Acknowledgments: review and acknowledge required policy documents

• Product Setup: the item setup workflow for Owned or DSV

Troubleshooting Common Supplier One Issues

A few recurring problems trip up suppliers, and most have simple fixes.

Missing or incomplete data: Usually means vendor records have not synced between Walmart's internal systems and your Retail Link account. This is a data refresh issue, not a permissions problem. Verify your vendor numbers under Apps > Supplier One > Vendor Summary and compare against the Retail Link Supplier Information Report.

Payments or invoices not appearing: First check for missing supplier bank details. Then confirm invoices are properly posted to the general ledger, and run the Unpaid Invoice Details report in the Reports section.

Access denied: Have your company's Retail Link administrator adjust your permissions.

Mobile access: Supplier One is built for laptops and desktops. It is not designed to work reliably on tablets or phones.

Supplier One and Deduction Recovery

Supplier One gives finance teams clear visibility into deductions and OTIF charges as they post, which is a real improvement over hunting through separate Retail Link apps. Turning that visibility into recovered revenue is a separate step, since disputes still run through the APDP and, for SQEP fines, EIPP. Platforms like iNymbus automate that dispute side, but the first move is simply knowing where in Supplier One your deductions surface and reviewing them regularly.
