A B2B file transfer is when businesses share data between each other. These transfers will typically involve moving structured data such as invoices, purchase orders or large datasets from one organization’s internal network, through an external network (such as a series of web servers) and into another organization’s internal network. B2B file transfer is typically accomplished with a tool like a file transfer protocol (FTP) server using encrypted protocols like HTTPS or SFTP. The FTP server acts as a centralized location where files can be uploaded, downloaded and managed under strict access controls between the organizations.
