## FAQ

**What is a lead generation tool?**

A lead generation tool is a software platform that helps sales and marketing teams find, contact, and qualify potential customers. These tools typically provide access to a large database of companies and professional contacts, along with features for filtering, data enrichment, and outreach.

**How much do lead generation tools cost?**

Costs vary widely, from around $50 per month for a single user with limited credits to over $25,000 per year for enterprise teams. Most providers use a credit-based system, where one credit equals one contact reveal. Pricing is typically per-seat and tiered based on feature access and credit volume.

**What is the difference between lead generation and data enrichment?**

Lead generation is the process of finding new potential customers, often by searching a database. Data enrichment is the process of adding missing information (like a phone number or job title) to an existing contact record you already have. Many platforms, like Clearbit and ZoomInfo, do both.

**How do I measure the ROI of a lead generation tool?**

Measure ROI by tracking the number of qualified meetings booked and deals closed from contacts sourced through the tool, then compare the revenue generated to the tool's annual cost. Also, consider time saved by reps who would otherwise be prospecting manually, which can be calculated by multiplying hours saved by their hourly cost.
