Buy, sell, ship. In that order.

ShipBob is built for selling into the United States. That's what its network is designed around, and it does that job well. If your growth is coming from outside the US, that model has you moving inventory into a US warehouse and then back out again. Portless ships direct from the point of production to 78 countries, so opening a new market doesn't mean opening a new warehouse.

ShipBob is domestic warehousing. You buy inventory, freight it in, store it, and ship from it. Portless is direct fulfillment. Your stock is inbounded the day it leaves the production line and ships straight to your customer anywhere in the world, with no domestic warehouse in the middle.

5 to 8 days to the door on express, to 78 countries. Orders placed before 16:00 China time ship the same day.

You reorder against live sales instead of a 90-day forecast. New stock is sellable one business day after it leaves the line, and because it lands in one pool, it serves every market at once.

When 90%+ of your volume is US domestic and you have no international plans. When you need automated EDI for wholesale. When Amazon is a major channel. And when your products are heavy, bulky, or sensitive: pet food, frying pans, supplements. Those economics favor sea freight and domestic storage, and ShipBob handles them well.
