For Walmart and Sam’s Club suppliers, Marketplace sellers, and their brokers

Walmart decisions need more than a confident answer.

Retail Reason helps with supplier operations, Scintilla, Marketplace, Walmart Connect advertising, and ProSpec specifications in private chat. Bring a question, check a plan, or work with a file. You can also connect Claude, Codex, and ChatGPT when you prefer to work there.

Use maintained retail guidance to work out what applies, what is missing, and what to check next. Maintained by a practicing retail advisor.

Independent of Walmart. It never touches your portals; you bring the question and the context.

Complete answer · Walmart supplier · Getting paid

Question:

Our EDI invoice was acknowledged. Why is it missing from Accounts Payable?

Answer:

A matching EDI acknowledgment does not establish that an invoice was accepted for payment. Read the actual result, then locate invoice-specific AP processing evidence. A 997 concerns syntax; payment status and money received are separate checks.

What applies
Walmart U.S. first-party suppliers using invoice-based payment. Match the supplier, invoice, PO and original control references before interpreting the response.
Confirm next
Record the AP application, search scope and check time. A manual-processing batch count is a lead, not proof of the individual invoice state. Give the next owner a specific evidence request.
Limit
An absent search result does not prove nonreceipt. Neither acknowledgment nor visibility alone establishes a due date or payment. Current account evidence is still needed.

Why not just ask your assistant

Maintained guidance for the work in front of you.

Use Retail Reason for everyday operating questions, with visible source dates and limits. Retain your advisor for decisions that need their judgment or representation.

What you have

A general AI subscription

Useful for drafting, summarizing, and reasoning across many subjects. For retailer-specific decisions, check which sources support the answer, when they were verified, and whether they apply to your situation.

What this adds

Retail Reason

Maintained retail guidance in your Retail Reason account or connected assistant. Review the available guidance dates, file references, and stated limits before acting. Higher-volatility facts are re-checked before they are relied on, and stale or time-sensitive details are called out.

What it does not replace

A retained advisory firm

Judgment, negotiation, and presence in the room, which software does not replace. If you already retain an advisor, this is the layer that answers the quick questions before they reach their inbox.

Choose a subscription for your team or your client workspaces.

What the quick-question layer costs in advisory time

How it works

Open your workspace. Ask in context. Check before acting.

No person sits between your question and the answer.

Open your workspace

Sign in to Retail Reason and open Chat for your company or client. Ask directly, with no separate Claude or ChatGPT subscription. Connected assistants remain optional.

A question, a problem you’re diagnosing, or a plan you want checked before it goes out. Add the retailer, role, tier, and timing that change the answer.

03

Act with the limits visible

Review the answer, any file references and guidance dates, and what still needs confirmation before acting.

Optional connections: Claude hosted, Claude Code, Codex CLI, ChatGPT.

What you can work on

Guidance across the work you do every week.

Ask in private chat, add authorized reports or drafts, and work toward an answer, a plan, or a file you can use. Retail Reason brings maintained guidance to each area below.

Investigate deductions, check item setup, and work through orders, replenishment, transportation, and compliance. Identify the evidence you need and the right next step.

Walmart supplier guidance

Scintilla & reporting

Understand what changed in the numbers.

Choose the right report and metrics, then analyze exports you upload. Check periods, filters, units, and missing data before explaining a sales or inventory change.

Scintilla and reporting guidance

Walmart Marketplace

Keep listings, fulfillment, and payments moving.

Get guidance on supplier onboarding, item data, deductions, merchandising, and compliance. Keep Sam’s Club systems, supplier relationships, and reporting distinct from Walmart.

Sam’s Club supplier guidance

Work through Sponsored Search, display, campaign planning, and measurement. Separate attributed sales from evidence of incremental sales before drawing a conclusion.

Walmart Connect guidance

ProSpec

Find the next step in specification work.

Work through product and supplier records, specifications, pack copy, and approval workflows. Identify what needs checking and who needs to act in ProSpec.

ProSpec guidance

You provide the context and files. Retail Reason does not retrieve portal data or take actions in retailer accounts. See how to use chat and files across this work.

Step two in practice

One detail changes the first check.

The same Marketplace question, with and without a margin floor.

Question

Our Buy Box win rate fell. Should we lower our price?

Context
Guidance · first check

Check published status, total price including shipping, and delivery promise. Ask for the margin floor; do not recommend a number.

Run the same offer-health, total-price, and delivery checks, then evaluate any price change against the supplied floor.

One detail changed. The fulfillment path stayed the same, but adding a margin floor made responsible price evaluation possible.

Who it is for

Four kinds of work. One real question from each.

Each question links to its complete public answer, with the date that answer was last verified.

Walmart suppliersLast verified September 13, 2026

Why did Walmart stop ordering your item?

Diagnose it in three steps: confirm the item’s Supply Item Status Code, confirm it is still listed rather than NIL, then compare valid stores with traited stores. Each branch points to a different cause and owner.

Walmart supplier guidance
Marketplace sellersLast verified September 2026

Why is your listing unpublished?

An unpublished listing has a named reason in Seller Center, under Catalog and then Unpublished Items. Most reasons fall into four classes: content and setup, compliance or Trust and Safety, pricing, or performance. That reason determines the fix.

Trust and limits

Useful guidance needs visible boundaries.

Confidence should come from seeing what an answer uses, what it cannot support, and what still needs to be checked.

Independent

Not affiliated with, endorsed by, or a product of Walmart Inc.

No portal connection

You supply the question, context, draft, or file. Retail Reason does not retrieve data from your retailer systems.

Visible support

Chat shows file references and guidance verification dates when available. Connected guidance responses include an as-of date and confidence class.

Refuses when support is thin

It can ask for context, name what cannot be supported, or abstain rather than fill a gap with invented certainty.

Plain data flow

Your context goes in. Nothing is read from your systems.

Website chat stores private conversations and files on Cloudflare. Relevant messages and selected files go to OpenAI for processing and review. An optional connected assistant also handles its own conversation under its terms. Retail Reason does not train its own models on customer content.
