Frequently Asked Questions
What is the difference between an outsourced SDR agency and a lead generation agency?
An outsourced SDR agency typically builds and operates a full outbound sales system, including hiring and training reps, while a lead generation agency focuses on generating leads or meetings. The key difference is that an outsourced SDR agency often aims to transfer the capability to the client's team, whereas a lead generation agency may provide a continuous service without building internal capability.
How long does it take to build an outbound system?
The timeline varies by agency and the complexity of the system. Some agencies can have a system live in 60 days, while others may take longer. It is important to clarify the timeline and milestones with the agency before committing.
Do I own the data and reps if I use an outsourced SDR agency?
It depends on the agency's model. Some agencies, like Outbound Operators, ensure that the client owns the system, the data, and the reps. Other agencies may retain ownership of the data or the reps. It is crucial to clarify ownership terms in the contract.
What is a phone-first outbound strategy?
A phone-first outbound strategy is an approach where the primary channel for reaching prospects is the phone, rather than email or social media. This strategy focuses on having live conversations with prospects to build relationships and drive pipeline.
How do I know if an outsourced SDR agency is the right fit for my company?
Consider your company's stage, goals, and resources. If you are a venture-backed B2B company that needs pipeline this quarter and wants to build a long-term capability, an agency that focuses on system installation and capability transfer may be the right fit. If you need ongoing, outsourced execution, a managed service provider may be a better option.
What are the key metrics to track for an outbound system?
Key metrics include dial-to-connect rate, conversation rate, meeting rate, and SQL rate. Tracking these metrics helps you understand the effectiveness of your outbound system and identify areas for improvement.
