Co-warehousing vs 3PL: which fits your business?
An honest side-by-side of the two most common warehouse models for small product brands. We sell co-warehousing — but we'll tell you when a 3PL is the better call.
Most product founders end up choosing between two models when they outgrow a garage or spare bedroom: co-warehousing (you rent the space and ship yourself) and a 3PL (a third-party stores inventory and ships orders on your behalf).
Both are valid. They optimize for different things, and the right answer depends on your order volume, margin, control preferences, and the cadence of your business — not on what one operator's sales team tells you.

FAQ
Co-warehousing vs 3PL — common questions
What's the main difference between co-warehousing and a 3PL?
In co-warehousing, you rent the physical space and run shipping yourself (or with a small in-house team). In a 3PL, the provider stores your inventory and ships orders on your behalf, charging per unit. Co-warehousing gives you control and a flat cost; a 3PL gives you operational outsourcing and variable per-unit pricing.
At what order volume should I switch from co-warehousing to a 3PL?
Most brands move from co-warehousing to a 3PL around 500–1,000 orders per day, when the labor cost of in-house picking and packing exceeds the per-unit fee a 3PL would charge. Many brands also stay in co-warehousing indefinitely because they value operational control over outsourcing.
Is a 3PL cheaper than co-warehousing?
It depends on your volume and product margin. At low volume (50–200 orders/day), co-warehousing is usually cheaper because 3PL per-unit fees + storage add up. At high volume (500+ orders/day), a 3PL can be cheaper because they have labor and packing automation efficiencies you can't match in a small suite.
Can I use both?
Yes. Some brands keep their highest-velocity SKUs in a co-warehouse for fast in-house shipping and use a 3PL for long-tail inventory. Others use a 3PL for their primary channel and a co-warehouse for B2B / wholesale fulfillment they want to keep in-house.
What about a 4PL or freight forwarder?
A 4PL coordinates multiple 3PLs and carriers on your behalf — usually relevant once you have $10M+ in revenue and complex international supply chains. A freight forwarder handles inbound import logistics. Both are usually paired with a 3PL or in-house warehouse rather than replacing them.
