If you want to open Walmart Marketplace in Missouri, you usually need to do five things in order:
- Choose your setup: sole proprietorship vs single-member LLC.
- Get your federal and Missouri registrations or registration decision in place before launch, but keep the Missouri in-state retailer-license rule separate from the marketplace-only vendor's use tax shortcut.
- Verify local permit, zoning, home-business, and city-tax rules, especially if you will operate in Kansas City.
- Open and verify your Walmart Marketplace seller account, complete the live checks Walmart Marketplace requires, and build a small first set of listings.
- Launch only after your product, tax, shipping, and compliance setup are ready.
Practical first-launch recommendation
If you are testing casually with minimal risk, sole proprietor can work.
If you intend to build a real Walmart Marketplace business, single-member LLC is usually the better long-term path.
Avoid these first-launch mistakes
- Assuming Walmart Marketplace marketplace collection means the Missouri retailer-license question is finished forever
- Using Form 149 before the Missouri tax-registration posture is actually supportable
- Treating Missouri's statewide fictitious-name filing like a county DBA
Missouri-specific friction
Missouri does not give beginners one perfectly clean marketplace-tax answer. The Department of Revenue says a marketplace seller selling only through a marketplace facilitator does not have to register, collect, or remit vendor's use tax. But the same Department's business-registration guidance also says a business making taxable retail sales from a location in Missouri must obtain a sales tax license.

- Form 149 is real and useful, but it is not a magic substitute for the rest of your Missouri setup. Resolve the retail-license question first, then use Form 149 in the way that matches that posture.
- Missouri uses a statewide fictitious name filing, not a county DBA, which trips up founders who are used to other states.
- Kansas City adds a real local-license, zoning, profits-tax, and county personal-property-receipt branch.
Walmart Marketplace-specific friction
Walmart publicly expects stronger seller onboarding than some marketplace channels, including business verification, business documents, and a state registration number for U.S. entities.

- Walmart wants either WFS or another B2C U.S. warehouse path with returns capability.
- Walmart's public rules are more restrictive than eBay for used-condition selling.
- Walmart's pricing rules and performance standards can affect listings and account health quickly if you launch sloppily.
Insurance reality
Physical-product sellers should think about commercial general liability and product liability coverage early, but the public Walmart evidence does not support treating it as a universal up-front seller requirement.

- Walmart's public liability-insurance policy says sellers must submit a certificate of insurance if they exceed $100,000 in GMV in any 12-month period or if Walmart notifies them directly.
- The public policy also says the coverage must include general and product liability limits of $1,000,000 per occurrence and $2,000,000 aggregate, with Walmart named as an additional insured in the required manner.
