How we compared
We built this comparison for sellers whose business already runs on Amazon and who are adding Walmart. That shaped what we weighed most: whether a tool covers both marketplaces well, whether it helps you recover money from FBA and WFS, and whether returns, shipping and profit live in one place or need extra apps.
Every competitor fact comes from the vendor's own website, checked in November 2026. Where we could not find a feature in a vendor's published features or integrations, we mark it as not listed instead of guessing. Prices change, so confirm them with each vendor before you buy.

What is an FBA or WFS reimbursement?
When Amazon or Walmart loses or damages your inventory in their warehouses, or receives fewer units than you shipped, you may be owed a reimbursement. Each program has its own claim rules and deadlines, so it pays to track cases closely.

Sellbrite and Base.com both have free plans, for up to 30 and 100 orders a month. CrazyVendor's plans start at $29 a month. Linnworks prices by quote, and Zentail starts at $300 a month plus usage.
Which tools support TikTok Shop?
In this comparison, Linnworks and Base.com list TikTok Shop integrations.
