Challenger Sale
A sales methodology popularized by Matthew Dixon and Brent Adamson (CEB). The Challenger teaches the customer something new about their business, tailors their approach, and takes control of the conversation. It is the most represented profile among top performers in their CEB study of more than 6,000 sales reps ("Selling Is Not About Relationships," Harvard Business Review, 2011).

Churn
The attrition rate measuring the percentage of customers who cancel their subscription or stop buying over a given period. High churn signals issues with satisfaction, onboarding, or product-market fit. In SaaS, reducing churn is often more profitable than acquiring new customers. Sales teams contribute by selling to the right profiles (aligned ICP) and setting realistic expectations during the sales process, avoiding post-signature disappointment.
Closing
The final phase of the sales cycle where the sales rep secures the prospect's formal commitment: contract signature, purchase order, or budget approval. Closing is not just a pressure technique: it is the natural outcome of a well-executed discovery, value demonstration, and objection handling process. Closing techniques include benefit summary, alternative close (choosing between two options), legitimate urgency, and usage projection.

Sales coach
A professional (often a manager or external consultant) who supports sales reps in developing their selling skills. Sales coaching differs from traditional training through its individual and contextual approach: listening to real calls, debriefing, role-playing, and personalized development plans. A good coach doesn't give answers but asks the questions that help reps find their own solutions. AI is transforming this field by making coaching accessible at scale.

Cold call
A prospecting phone call to a contact who has not requested to be contacted. Cold calling remains one of the most challenging and valued skills in B2B sales: the rep must capture attention in seconds, legitimize their outreach, identify a need, and book a meeting, all in under two minutes. The key: thorough preparation (prospect research), a personalized opening, and the ability to handle initial objections ("I don't have time," "send me an email").

Cold email
A prospecting email sent to a contact who has not expressed prior interest. Unlike spam, a good cold email is highly personalized, concise (under 100 words), focused on a specific problem the recipient faces, and offers clear value. Cold email sequences typically combine 3 to 5 emails spaced a few days apart, with different angles. The average reply rate ranges from 2% to 8%, but can exceed 15% with precise segmentation and targeted copywriting.
Conversation Intelligence
Technology that records, transcribes and AI-analyzes sales calls to surface insights: talk-to-listen ratio, keywords, topics covered, sentiment. Reference tools: Gong, Chorus, Fireflies.

Conversion rate
The percentage of prospects who move from one funnel stage to the next. In B2B sales, multiple conversion rates are tracked: cold call to meeting (typically 2-5%), demo to proposal (30-50%), proposal to signature (20-40%). Tracking these rates at each pipeline stage identifies bottlenecks and focuses training efforts where the impact is greatest. A rep who converts well at the demo stage but not at closing has a negotiation problem, not a pitch problem.
CRM (Customer Relationship Management)
Customer relationship management software that centralizes all interactions between a company and its prospects/customers: contacts, exchange history, current opportunities, tasks. In B2B, the CRM (Salesforce, HubSpot, Pipedrive...) is the rep's daily tool. It feeds sales forecasts, enables management to track the pipeline, and facilitates team collaboration. A well-maintained CRM is the collective memory of the sales team.
Cross-selling
A sales technique of offering complementary products or services to an existing customer. For example, a SaaS vendor selling a CRM might offer an emailing or analytics module. Cross-selling is more profitable than acquisition: the customer already knows you, trust is established, and the sales cycle is shortened. The key is to propose add-ons that address a real identified need, not to push a catalog.
Sales cycle
The set of stages a prospect goes through from first contact to contract signature. In B2B SaaS, a typical cycle includes: prospecting, qualification, discovery call, demonstration, proposal, negotiation, and closing. Duration varies considerably: from a few days for self-service software to 6-12 months for an enterprise contract. Shortening the sales cycle without sacrificing quality is a core objective of sales enablement.
