Part 2 of 3

Compare sole proprietor and LLC

The side-by-side setup comparison.

Short answer

Read both setup paths before you decide which one you want the rest of the launch flow to follow.
  • Best if you want the cheapest and simplest start.
  • Maryland does not require a separate entity-formation filing just to exist as a sole proprietorship.
  • Faster launch.

Do next: Review sole proprietor.

Save the path you want to optimize around

The unchosen setup stays visible for comparison, but the chosen one gets visual priority so the reading path feels more intentional.

Sole proprietor

Best for

Best for

Best if you want the cheapest and simplest start.

Best for

Best for

What it means

  • The reviewed SDAT fee schedule lists a $100 filing fee and Maryland requires a resident agent.
  • Maryland also keeps the annual-report and business-personal-property branch visible after formation.
  • Default single-member LLC federal treatment usually stays pass-through unless you elect otherwise.

Why someone chooses it

  • Liability protection.
  • Cleaner setup for banking, vendors, bookkeeping, and scaling.
  • Better fit for sourcing, branding, insurance, and later hiring.

Main downside

Higher setup friction and recurring maintenance than a sole proprietorship

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 Maryland.
  • The state marketplace-seller rules are helpful, but they do not erase the separate entity, local, employment, or mixed-channel branches.
  • Walmart publicly expects stronger seller onboarding than some marketplace channels, including business verification, business documents, and a state registration number for U.S. entities.
  • 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.

Do next: Review maryland-specific friction.

Why this matters

Maryland-specific friction

Main takeaway

The state marketplace-seller rules are helpful, but they do not erase the separate entity, local, employment, or mixed-channel branches.

Watch for

  • Maryland still pushes naming, zoning, and local-permit questions down to the county or city level in practical launch work.
  • Baltimore adds a separate local license, zoning, occupancy, or local-tax layer if you operate there.

Walmart Marketplace-specific friction

Main takeaway

Walmart publicly expects stronger seller onboarding than some marketplace channels, including business verification, business documents, and a state registration number for U.S. entities.

Watch for

  • 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

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 up-front seller requirement.

Watch for

  • 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.
