Frequently Asked Questions

What is a realistic SQL rate for outsourced lead generation?

Rates vary significantly by target market, with enterprise programs typically achieving 8% to 10% and SMB programs reaching 15% to 18%. Companies should set expectations based on their specific target account profile and sales cycle complexity.

How do outsourced lead generation costs compare to in-house programs?

The 54% cost premium reflects partner margins and ramp inefficiencies. Companies offset higher costs through reduced hiring risk and faster program launch timelines.

What performance metrics should be included in partner contracts?

Lead volume, SQL rate, and appointment show rate are the three most commonly tracked metrics in outsourced lead generation contracts. Contracts should specify measurement definitions and reporting cadence to avoid disputes.

How long should companies expect partner ramp periods?

Companies can accelerate ramp through comprehensive ICP training, regular feedback sessions, and clear success criteria. Ramp periods extending beyond 6 months typically indicate partner capability or cultural fit issues.

What are the primary reasons outsourced programs underperform?

Insufficient account research and poor lead qualification are the top two performance issues according to The Starr Conspiracy's analysis of 34 client programs. 43% of underperforming programs lack adequate prospect research depth, while 38% struggle with lead qualification consistency. Regular training and performance calibration sessions address both issues effectively.

How do appointment conversion rates compare between in-house and outsourced teams?

The 6-point gap reflects handoff challenges and reduced account context when external teams initiate relationships. Strong partner partnerships include structured handoff processes and account intelligence transfer protocols.
