Metapack is a company that specialise in deliveries and interfacing with all the carriers. Whichever carrier you use they can integrate to it saving all the hassle of creating links with each one.
In the Metapack user interface you can decide which carrier, print labels etc. or this can be done automatically based on criteria you set. They print in the correct format to stick straight on the box. If you have multiple carriers then you tell it to pick the lowest cost etc. You can also amend the information if needed.
Metapack will improve the delivery experience for customers and users. If the carrier has tracking available this tracking number can be emailed to the customer so they can track their own order. If there is no success delivering the parcel then it can also email them again to rearrange delivery. This contact with the customer should reduce the number of calls about “where is my delivery”.
