# Seller > What is the end to end delivery process?

A bundle with premium surface products added by a seller is considered a "unit for purchase" by the buyer. A Maximum of 6 such bundles can fit in one 20-foot container. The weight of premium surface products that fit in each bundle must be equal to or lesser than the maximum weight allowed in each bundle. This weight will be calculated automatically based on the dimensions of the premium surface products and the seller will be notified of this information at the time of adding the bundles. Once purchased, the bundle transitions through different statuses during the end-to-end delivery process as shown below.  Buyers can issue a purchase order by adding bundles of different premium surface products from different sellers, and collaborate with sellers and shippers during this end-to-end process.
