Compare sole proprietor and LLC

The side-by-side setup comparison.

Short answer

Up next Money and risk

Part 3 of 3

See the money and risk realities before you spend

The upfront friction and risk notes that shape the launch decision.

Short answer

These are the friction points most likely to catch a new Walmart Marketplace operator off guard in Illinois.
  • Illinois' ST-1 marketplace-sales rule is clear, but it does not automatically close the separate Illinois registration and resale-documentation branch.
  • Walmart publicly expects stronger seller onboarding than some other marketplace channels, including business verification, supporting documents, and a catalog that fits Walmart's policy stack.
  • 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 day-one requirement for every seller.

Do next: Review illinois-specific friction.

Why this matters

Illinois-specific friction

Main takeaway

Illinois' ST-1 marketplace-sales rule is clear, but it does not automatically close the separate Illinois registration and resale-documentation branch.

Watch for

  • Illinois pushes many naming, zoning, and local-permit questions down to counties and municipalities.
  • Chicago adds a real home-occupation and license-fee branch if you operate there.

Walmart Marketplace-specific friction

Main takeaway

Walmart publicly expects stronger seller onboarding than some other marketplace channels, including business verification, supporting documents, and a catalog that fits Walmart's policy stack.

Watch for

  • Walmart expects either WFS or another B2C U.S. warehouse path with returns capability.
  • Walmart's public rules are stricter than eBay for used-condition selling.
  • Walmart's performance standards and pricing rules can affect listings and account health quickly if you launch sloppily.

Insurance reality

Main takeaway

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 day-one requirement for every seller.

Watch for

  • Walmart's public liability-insurance policy says a seller must submit a COI if the seller exceeds $100,000 in GMV in any 12-month period or if Walmart notifies the seller directly.
  • The same public policy 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 way.
