A partner salesperson who has taken at least one qualified selling action for your solution in the current quarter. A qualified action is a real selling move (putting your solution into a live pitch, demo, or proposal, co-selling into a customer meeting, working a genuine lead, or closing a deal that includes it), not a learning action like finishing a certification or downloading a battlecard. A rep who has been trained but has not put your product in front of a customer is enabled, not active.
The share of a partner's reps who clear this bar in a given quarter is the Active Seller Rate, the leading channel metric that predicts partner-sourced revenue. The guide covers the full five-condition definition of a qualified action, the worked math, and the three conditions (confidence, motivation, access) that move the number.
