SupplierSide

SupplierSide, often styled supplierside, is a term that may refer to two related concepts in digital commerce and business software: a supplier-side platform used in programmatic advertising, and a procurement software product or company bearing the name SupplierSide.

In programmatic advertising, a supplier-side platform (SSP) is technology used by publishers to manage, sell, and optimize available ad inventory. SSPs connect to ad exchanges and demand-side platforms to facilitate real-time auctions for impressions. Publishers use SSPs to automate inventory offering, set price floors, and compare demand partners. Key features typically include inventory management, real-time bidding or header bidding support, price optimization, yield analytics, and comprehensive reporting. By exposing inventory to multiple buyers, SSPs aim to maximize revenue while maintaining control over where and how ads appear, as well as ad quality and compliance.

SupplierSide as a brand or product refers to procurement software offerings that focus on supplier onboarding, catalog management, and procurement workflows. Such platforms commonly support supplier registration, document verification, contract management, purchase orders, invoicing, and payment reconciliation. They are designed to improve supplier data quality, streamline collaboration between buyers and suppliers, and enable integration with broader ERP, e-procurement, and finance systems. Availability and specific features vary by vendor, and the term may denote either a standalone product or a suite within a larger procurement platform.
