The Ultimate B2B Sales Glossary (100 Terms To Know)

by | Sep 22, 2025 | Sales and Marketing Strategy

Sales conversations are full of jargon. Terms get reused, misused, and stripped of meaning. Even experienced salespeople can find themselves nodding through phrases that sound familiar but aren’t clearly defined.

The problem? Sales vocabulary isn’t just semantics, it’s structure. If your team can’t align on what a “lead,” a “qualified opportunity,” or a “next step” really means, your pipeline will drift. Forecasts will wobble. Deals will stall.

This glossary is designed to fix that. No filler, no buzzwords. Just the 100 most useful, clearly defined sales terms, written for B2B teams that care about building a system, not winging it.

Let’s get into it.

Lead generation is the starting point of every structured sales process. But most teams rush it. This section defines the essential terms used in prospecting, targeting, and qualifying leads, from cold outreach to MQL and SQL definitions. Start here to clean up the top of your sales funnel.


Most sales problems stem from poor qualification. Discovery isn’t just about asking questions, it’s about finding out if a deal is worth pursuing, and how to move it forward. This section breaks down key frameworks, stakeholders, and definitions to help sales teams build structure into every early-stage conversation.


A healthy pipeline isn’t just full, it’s structured. This section covers how deals move from discovery to close, how to track them, and how to build a process that reflects real buyer behaviour. Use this to sharpen your sales process and improve forecast accuracy.


Tools don’t fix a broken sales process, but the right systems make good habits stick. This section covers the core platforms, features, and functions that support scalable sales execution, from CRM basics to automation and tracking.


B2B sales is a team effort, but only if roles are clearly defined. This section outlines who does what, from prospecting and closing to systems and strategy. Aligning roles to your sales process is essential for scaling sustainably.


Sales isn’t about personality, it’s about process. These frameworks shape how teams qualify, position, and close, and help salespeople focus on solving, not just selling. This section includes classic methods, modern models, and core principles behind the 1000Steps sales system.


Understanding how people buy is just as important as knowing how to sell. This section explains key psychological triggers, decision stages, and closing behaviours that shape deal outcomes, especially in complex, multi-stakeholder sales environments.
