Walmart WFS vs Amazon FBA: Where Your Next SKU Should Go

Walmart WFS vs Amazon FBA comparison illustration
The honest answer to "WFS or FBA?" is it depends on the SKU. Here's how we frame it for clients.
Start with fees, but don't stop there
WFS storage and fulfillment fees are often lower, but lower fees on a channel with less demand isn't a win. Model contribution margin per unit sold, not fee percentage.
Match the SKU to the channel's demand
- High-velocity, brand-name items usually justify both channels
- Long-tail or niche items often do better on the less saturated channel
- Restricted categories may only be viable on one
Split inventory deliberately
Don't mirror your catalog blindly. Splitting by expected sell-through keeps capital from sitting idle in the wrong warehouse.
Whichever way you go, prep both to spec from day one — our FBA prep checklist covers the Amazon side.
