Sales Pipeline

A sales pipeline is the structured set of stages a business uses to track and manage every live opportunity, from the first contact with a prospective customer through to a deal won or lost. Unlike a sales funnel - which shows aggregate conversion rates across all leads - a pipeline tracks individual opportunities through each stage, making it possible to see which deals need attention, where the bottleneck is, and what revenue the business can realistically expect to close.

What the Stages Represent

Most B2B pipelines run five to seven stages. The exact labels vary by business and sector, but the underlying logic is consistent: each stage should represent a concrete milestone in the buyer's decision-making process, not a task the seller has completed. Sending a proposal is a seller activity. The buyer reviewing and acknowledging it is a buyer milestone. Pipelines built around seller activities produce forecasts that routinely miss by a wide margin.

A typical stage sequence: enquiry or prospecting, qualification, needs assessment, proposal, negotiation, and closed (won or lost). Businesses with longer sales cycles or more complex approval chains - such as those supplying construction projects, AV system integrations, or large corporate accounts - often add dedicated stages for procurement review or contract sign-off.

The practical rule: if two consecutive stages cannot be separated by a specific buyer action or decision, merge them.

Keeping the Pipeline Honest

A pipeline only forecasts accurately if the deals inside it are real. The most common problem is "zombie pipeline": opportunities that remain in the active pipeline long after the buyer has stopped engaging or chosen a competitor. These inflate the total pipeline value and make forecasts unreliable.

Three habits keep a pipeline clean. First, each stage should have clear exit criteria - a verifiable condition that must be met before a deal moves forward. Second, any opportunity that has not shown buyer-side movement within 21 days should be flagged for review. Third, won and lost outcomes should both be recorded with a reason, because lost deals are often more useful for improving the process than wins.

Businesses that track stage-to-stage conversion rates can quickly identify where their process is leaking. If fewer than 40% of deals advance from one stage to the next, the exit criteria for that stage are likely too loose or the stage definition is unclear.

How Pipeline Health Connects to Revenue

A well-maintained sales pipeline gives a business three things: a realistic view of expected revenue, early warning when top-of-funnel activity is falling short, and a factual basis for judging whether the team's workload is sustainable. Businesses that manage opportunities through email inboxes or spreadsheets alone typically struggle to answer whether enough business will close in any given month.

A pipeline coverage ratio of at least 3x your revenue target is a useful benchmark - meaning if you need to close £100,000 in a quarter, you should have at least £300,000 of active opportunities to account for deals that slip or fall away. Coverage below 3x is a signal to increase top-of-funnel activity before the shortfall reaches closed revenue.
