What is drop shipping?

drop ship

Verb (used with object), drop-shipped, drop-shipping.

To send purchased goods directly from the vendor or manufacturer to a customer or retailer with no intermediate distributor, but billed through a third party.

Drop Shipping Program

How warehouse drop shipping works:

Drop ship is a fulfillment model that ships products directly to the consumer on behalf of the retailer.

How Drop Shipping Works

When a 3PL is in the mix, drop shipping works like this:

  • Retailers will set up items on their website with the help of the vendor
  • The vendor provides ongoing inventory level information, though some 3PLs assist with this process when they’re part of the drop shipping process
  • Consumer places order with retailer
  • The retailer places order with the vendor
  • The vendor conveys the order to the third-party logistics provider
  • The 3PL provider ships to the consumer on the vendor’s behalf
  • The 3PL keeps the retailer updated with continuous order/shipment information
  • The retailer provides the consumer with continuous order/shipment information

Benefits of drop shipping for 3PL, 4PL and other logistics providers:

Drop shipping is a ripe opportunity for third-party logistics providers to better support their retail and supplier trading partners while maximizing the potential for profitable collaborative relationships.

Make money on single-parcel units.

Sending inventory parcel-by-parcel is more resource intensive, but retailers are also willing to pay a premium on it.

Appeal to more trading partners.

More retailers and suppliers are looking for 3PLs to help them satisfy customers with an eCommerce track and trace option.

Unlock possibilities with existing partners.

It’s likely retailers you work with already are seeking drop-ship-capable third-party logistics companies.

Improve customer loyalty.

When you’re able to ship full-load, partial loads and parcel-by-parcel in the form of drop shipping, your partners are more likely to stick with you.

You’re probably already halfway there.

3PLs are already in a position to help get products from point A to point B, from the supplier to the retailer or directly to the consumer.

New product testing.

Help retailers and suppliers test new products. Selling a product online only with drop shipping quickly lets retailers and suppliers know whether or not it is performing.
