Resources
How Sellers Use Fulfillment
The problems sellers bring to a 3PL, and what changes once someone else handles the packing.
The packing table was the bottleneck.
A live seller finishes a big show with hundreds of small orders, each with a different mix of items. With a 3PL, the show stock is already in the warehouse, and the team picks, bundles and ships every order.
Live sellerTikTok Shop and Whatnot · Read the story →
One stock, many marketplaces.
A seller on Amazon, Walmart and eBay was splitting stock between rooms and overselling by accident. With one shared stock in one warehouse, every channel ships from the same place.
Multichannel sellerMarketplaces and own store · Read the story →
The garage was full.
A growing brand ran out of space for inventory and spent evenings packing. Moving the stock to a warehouse freed the room and the time to focus on sales.
