Module 2 · Lesson 1
Seller Center vs Walmart Connect Ad Center
What you’ll learn
- What Seller Center handles versus what Ad Center handles
- How your ad account links to your Marketplace account
- User roles — and why admin access matters for billing
- Where you’ll spend your day-to-day campaign time
Two platform names come up constantly, and mixing them up is the first thing that slows new advertisers down. Let’s separate them cleanly so you always know where to click.
Two platforms, two jobs
Walmart splits your work across two connected tools:
Seller Center
Where you run your Marketplace business — listings, inventory, orders, pricing, performance and account billing settings. It’s your storefront’s back office.
Walmart Connect Ad Center
Where you run your advertising — launching, managing and optimising campaigns with the fullest toolset, including 2026’s AI features. This is your campaign cockpit.
A simple rule of thumb: if it’s about what you sell, it lives in Seller Center. If it’s about promoting what you sell, it lives in Ad Center.
Where you’ll actually work
You’ll set things up in Seller Center, but you’ll spend the real campaign hours — keywords, bids, optimisation — inside Ad Center. When this course says “open your campaign,” it means Ad Center.
How they link together
Your self-serve ad account is tied to your Seller account. That link is what makes the whole system work: it’s how Walmart knows which products you can advertise, whether they hold the Buy Box, and — as you’ll see in Lesson 4 — how your ad spend gets billed against your Seller balance.
You sign in to Ad Center with your Walmart Connect Ad Center credentials. From there you can manage the ad accounts your login is attached to.
User roles — this matters
Access on an ad account isn’t all-or-nothing. There are different permission levels, and one distinction trips people up around billing:
- Admin — full control, including Billing Manager (adding and editing payment details).
- Write — can build and edit campaigns, but cannot access Billing Manager.
- Read — view-only.
Common setup snag
If you or a teammate hit an “Access Denied” error on billing, it’s almost always a role issue — only admin users can open Billing Manager. Sort out who holds admin before you try to set up payments in Lesson 4.
Quick recap
- Seller Center runs your Marketplace business; Ad Center runs your advertising.
- Your ad account links to your Seller account — that link drives eligibility and billing.
- Roles matter: only admin users can access Billing Manager.
- Day-to-day campaign work lives in Walmart Connect Ad Center.
