A seller must go through a number of formalities and processes in order to sign up as an Amazon seller and continue selling successfully. These comprise registration, photo-filled product catalogs, pricing schemes, and marketing tactics. Successful selling takes a high level of expertise and knowledge, and sellers can enroll in the Amazon Sellers training programme or seek help from a network of qualified Amazon Service Providers. These service providers are a part of Amazon’s SPN offerings, which they design to assist shops with joining Amazon, selling successfully there, and maintaining compliance.
