How does Prisma for Sellers Work?

Prisma for Sellers is a direct line between sellers and buyers — enabling the sales process from RFP, through negotiation, and I/O revisions. All RFPs, proposals, orders and revisions are located in one place, with instant notifications. Additionally, as you interact with buyers across every stage of the transaction, the platform tracks the full transaction history along the way — so you know when a line item or revision was approved and who approved it.


Prisma for Sellers enables secure online transactions, with access anytime and anywhere through an intuitive web-based interface. The platform can be deployed as stand-alone system, or as an integrated solution that interfaces with a publisher’s existing media management platform.
