Lead Supplier

The source of leads in a distribution system — typically a marketing partner, affiliate, or lead-gen vendor.

Full definition

A lead supplier is any person, company, or channel that originates leads and sends them into a distribution system. Suppliers can be affiliate marketers, comparison sites, inbound web forms, outbound call centers, or partner networks. In most modern platforms, suppliers submit leads through a web form, an API endpoint, or by forwarding emails to a unique campaign address. The platform records who sent the lead, when it arrived, what data it contained, and whether it passed validation — creating an audit trail that lets operators resolve disputes and measure supplier quality over time. Metrics that matter on the supplier side include lead quality (how often their leads convert), duplication rate, and return rate (how often buyers reject leads as invalid). Suppliers with consistently high quality earn preferred status and better payouts.
