Sales funnel

A sales funnel is a model that visualizes the path prospects take on their journey to becoming a customer. It is called a funnel because it is wide at the top, representing the large number of potential buyers at the awareness stage, and narrows at each subsequent stage as prospects are qualified or drop out. This framework helps sales and marketing teams map and measure the entire buying process.

The Stages of a B2B Sales Funnel

While the specific stages can vary, a typical B2B sales funnel includes several key milestones that represent increasing buyer commitment. The process begins with lead generation to attract potential customers.

• Awareness/Lead: The prospect becomes aware of a problem and discovers the company as a potential solution.
• Interest/MQL: The prospect demonstrates interest by engaging with marketing content, becoming a Marketing Qualified Lead (MQL).
• Consideration/SQL: The sales team validates the lead's fit and intent, qualifying them as a Sales Qualified Lead (SQL).
• Intent/Opportunity: The SQL confirms a clear need and a desire to evaluate the solution, becoming a sales opportunity.
• Evaluation/Proposal: The prospect evaluates a formal proposal or demo.
• Purchase/Closed-Won: The prospect signs a contract and becomes a customer.

How Sales Funnels Are Used

The funnel is more than a conceptual model; it is a practical tool for managing revenue.

Forecasting: By knowing the number of prospects at each stage and the historical conversion rates between stages, revenue leaders can predict future sales outcomes. This data is critical for calculating metrics like pipeline coverage and setting realistic quotas.

Process Diagnosis: The funnel reveals bottlenecks in the sales process. A sharp drop-off between two stages indicates a point of friction that needs investigation. For instance, a low MQL-to-SQL conversion rate might signal a misalignment between sales and marketing on lead quality. The Revenue Operations team is often responsible for this analysis.

The Modern Alternative: The Bowtie Funnel

The traditional sales funnel's primary limitation is that it ends when a deal is closed. This model does not account for the post-sale customer lifecycle, which is critical in subscription-based businesses.

To address this, many organizations now use the bowtie funnel. This model visualizes the customer journey as two connected funnels: one for acquiring new customers and a second, mirrored one for retaining and expanding revenue from those customers through adoption, loyalty, and advocacy.
