Piggy backing

Explanation: Piggy back exporting is done by suppliers of a product and entails them supplying a certain function of the business only and just buying the actual product from local sellers. Another option can be that the supplier works with the local seller, and sells the seller's goods on behalf of seller for a commision. The suppliers are known as the carriers and the local sellers are known as the riders.

The customer entering the foregin market is the rider, and the suppliers supplying the parts ahd customer service is the carrier. The customer does not fully need to produce the product from scratch, and is able to acquire this from the suppliers who already have it. The custoemr, who is the rider, is thus able to "ride" on the back of the "carriers" back and ideas set in motion for their product.
