Sales & Marketing Definitions: The Complete Glossary for Small Business Owners

Sales and marketing are two distinct disciplines that work best when tightly aligned. Marketing creates awareness and generates leads. Sales converts those leads into customers. This glossary covers the terminology across both functions — because for most small business owners, they’re two parts of the same job.

A–C

Account-Based Marketing (ABM)

A B2B strategy that treats individual target companies (accounts) as markets of one. Instead of casting a wide net, ABM focuses marketing resources on a defined list of high-value target accounts with highly personalized outreach. More relevant for businesses selling to other businesses than for consumer-facing companies.

Attribution

The process of identifying which marketing touchpoints contributed to a conversion or sale. First-touch attribution gives credit to the first interaction. Last-touch gives credit to the final touchpoint before conversion. Multi-touch models distribute credit across the full journey. Attribution is complex in practice — customers rarely take a straight-line path from awareness to purchase.

B2B (Business-to-Business)

A business that sells to other businesses rather than directly to consumers. B2B sales cycles are typically longer, involve more decision-makers, require more trust-building, and command higher contract values. Marketing to businesses emphasizes expertise, ROI, and case studies more than emotional appeals.

B2C (Business-to-Consumer)

A business that sells directly to individual consumers. B2C transactions are usually faster, more emotional, and lower in average value than B2B. Marketing to consumers tends to emphasize emotion, identity, and immediate benefit. Many small service businesses are technically B2C even if their customers are businesses (a landscaper serving homeowners is B2C).

Bottom of Funnel (BOFU)

The final stage of the buying journey where prospects are actively deciding between options and ready to make a purchase. BOFU marketing focuses on conversion — case studies, testimonials, free consultations, demos, strong CTAs, and competitive comparisons. Most businesses invest too little here relative to their top-of-funnel efforts.

Buyer Journey

The process a potential customer goes through from first becoming aware of a problem to making a purchase decision. Typically broken into three stages: Awareness (they have a problem), Consideration (they’re evaluating solutions), and Decision (they’re choosing a provider). Effective marketing creates touchpoints at each stage of the journey.

Churn Rate

The percentage of customers who stop doing business with you over a given time period. Churn rate is critical for subscription or retainer-based businesses. High churn means you’re constantly replacing lost customers rather than compounding growth. The fastest path to growth is usually reducing churn alongside acquiring new customers.

Cold Outreach

Contacting potential customers who have had no prior relationship with your business. Cold email, cold calling, and cold LinkedIn outreach all fall in this category. Cold outreach requires more personalization and value upfront than warm outreach because you haven’t yet earned any attention or trust.

CRM (Customer Relationship Management)

Software used to manage interactions with prospects and customers — tracking leads, conversations, deals, and follow-ups. A CRM is the operational backbone of a sales process. Without one, leads fall through the cracks and follow-up becomes inconsistent. Popular options for small businesses include HubSpot (free tier), Pipedrive, and Zoho CRM.

Customer Acquisition Cost (CAC)

The total cost of acquiring a new customer, including all marketing and sales expenses. CAC = Total marketing + sales spend ÷ Number of new customers acquired. Understanding your CAC is essential for evaluating channel effectiveness and ensuring your business model is profitable. CAC should always be compared to Customer Lifetime Value.

Customer Lifetime Value (CLV / LTV)

The total revenue a business can expect from a single customer over the entire relationship. LTV is the context that makes CAC meaningful. A $500 CAC is unsustainable if average LTV is $600, but very reasonable if average LTV is $6,000. Increasing LTV through repeat business, referrals, and upsells is often more profitable than acquiring new customers.

D–L

Discovery Call

An initial conversation between a salesperson and a prospect designed to understand the prospect’s situation, needs, goals, and pain points — before pitching a solution. Good discovery calls listen far more than they talk. The information gathered in discovery is what makes a subsequent proposal genuinely relevant rather than generic.

Email Marketing

Using email to communicate with prospects and customers — newsletters, promotional offers, nurture sequences, and transactional messages. Email marketing consistently delivers among the highest ROI of any marketing channel ($36–$40 return per $1 spent is commonly cited). The key assets are a quality list, relevant content, and consistent sending cadence.

Follow-Up

Any subsequent contact with a prospect after an initial touchpoint. Most sales are not made on the first contact — research suggests it takes 5–12 touchpoints before a prospect is ready to buy. Systematic follow-up — through email sequences, calls, or social connections — is one of the biggest revenue opportunities most small businesses fail to capitalize on.

Ideal Customer Profile (ICP)

A detailed description of the type of customer that is the best fit for your business — they need what you offer, can afford it, are easy to serve, and become loyal advocates. Your ICP defines who to pursue, who to deprioritize, and who to politely turn away. Selling to customers outside your ICP often leads to scope creep, low margins, and weak referrals.

Inbound Marketing

A strategy that attracts potential customers to your business through valuable content and experiences — blog posts, SEO, social media, and free resources — rather than interrupting them with cold outreach or ads. Inbound leads typically convert at higher rates because they arrive with pre-existing intent and trust. Takes time to build but compounds over time.

Lead

A person or business that has expressed interest in your product or service. Leads vary widely in quality — a form submission from someone ready to buy this week is very different from someone who downloaded a free guide with no immediate need. Qualifying leads early saves time and prevents sales effort going toward people who were never going to convert.

Lead Generation

The activities and tactics used to attract and capture potential customers. Lead gen channels include SEO, paid ads, referrals, content marketing, networking, social media, and cold outreach. Each channel has different cost, volume, and quality characteristics. Most successful businesses diversify across multiple lead sources rather than relying on one.

Lead Magnet

A free resource offered in exchange for contact information — typically an email address. Guides, checklists, templates, calculators, and free consultations are common lead magnets. A lead magnet works best when it solves a specific, immediate problem for your ideal customer — one closely related to what you sell.

Lead Nurturing

The process of building relationships with leads who aren’t yet ready to buy. Nurturing involves consistent, valuable communication — typically through email sequences, retargeting, and content — that keeps you top-of-mind until the prospect is ready to move forward. Most leads that don’t convert immediately are not lost — they just need more time and the right touchpoints.

Lead Qualification

The process of determining whether a lead is a good fit and ready to buy. Common qualification frameworks include BANT (Budget, Authority, Need, Timeline) and MEDDIC. Qualifying leads before investing significant sales effort prevents wasted time on prospects who were never going to close.

M–P

Marketing Funnel

A model describing the stages a potential customer moves through from first awareness to purchase. The classic funnel: Awareness → Interest → Consideration → Intent → Conversion. The funnel narrows at each stage — many people become aware, fewer develop interest, fewer still convert. Identifying where prospects are dropping off is the key to improving conversion rates across the funnel.

Marketing Qualified Lead (MQL)

A lead that marketing has determined is likely to become a customer based on engagement signals — pages visited, content downloaded, emails opened, or forms submitted. MQLs are typically handed off to sales for follow-up. The MQL threshold varies by business but should be defined clearly to ensure sales and marketing are aligned.

Middle of Funnel (MOFU)

The consideration stage of the buyer journey. Prospects here know they have a problem and are evaluating their options. MOFU content includes comparison guides, case studies, detailed service pages, webinars, and email nurture sequences. The goal is to build enough trust and credibility that they choose to move toward a sales conversation.

Net Promoter Score (NPS)

A customer loyalty metric based on one question: “How likely are you to recommend us to a friend or colleague?” Scored 0–10. Scores of 9–10 are Promoters (loyal advocates), 7–8 are Passives, 0–6 are Detractors. NPS = % Promoters − % Detractors. A high NPS correlates with referral growth and low churn.

Objection Handling

The practice of addressing concerns prospects raise during the sales process — price, timing, trust, competition, or uncertainty. Effective objection handling doesn’t argue with or dismiss concerns — it acknowledges them, provides relevant information, and redirects toward value. Common objections are predictable and should be prepared for in advance.

Outbound Marketing

Marketing that pushes messages outward to a broad audience, regardless of whether they’ve expressed interest — paid ads, cold email, direct mail, trade show presence, cold calls. Outbound generates awareness quickly but typically has lower conversion rates than inbound because the audience hasn’t opted in. Most growth strategies require a mix of both.

Pipeline

A visual representation of all active sales opportunities at different stages of the buying process. Managing your pipeline means knowing what’s in each stage, how much it’s worth, and what action is needed to move each opportunity forward. A well-managed pipeline prevents both feast-or-famine revenue cycles and surprises about forecast.

Proposal

A formal document outlining your recommended solution, scope of work, pricing, and terms for a potential client. A strong proposal isn’t just a quote — it demonstrates understanding of the client’s situation, articulates specific outcomes, and builds the case for your approach. Proposals that win are tailored to the discovery conversation, not templated from a generic document.

Prospecting

The process of identifying and researching potential customers who fit your ideal customer profile. Prospecting is the front end of the sales process — before any outreach happens. Good prospecting focuses effort on the highest-probability accounts rather than spray-and-pray outreach to anyone with a pulse.

R–W

Referral Marketing

Actively encouraging and incentivizing existing customers to refer new ones. Referrals are among the highest-quality leads a business can receive — they come pre-qualified and pre-trusting. Despite being the most effective lead source for most service businesses, referral programs are rarely formalized. A simple ask at the right moment captures enormous value that would otherwise be left on the table.

Sales Cycle

The average time it takes to move a prospect from first contact to closed deal. Sales cycle length varies dramatically by business type — a retail sale might close in minutes, while a B2B services contract might take weeks or months. Understanding your sales cycle length informs how much pipeline you need to maintain consistent revenue.

Sales Enablement

The resources, tools, and content provided to salespeople to help them sell more effectively — case studies, proposal templates, objection guides, competitive comparisons, and email scripts. For small business owners doing their own selling, sales enablement means building these materials for yourself.

Sales Qualified Lead (SQL)

A lead that sales has determined is ready for a direct sales conversation — they have the need, budget, authority to decide, and are actively looking for a solution. SQLs typically have a higher intent signal than MQLs. Passing leads to a sales conversation before they’ve reached SQL stage often results in wasted effort and pushback.

Top of Funnel (TOFU)

The awareness stage of the marketing funnel. Prospects here are just discovering a problem or need — they may not yet know what solutions exist or that your business does. TOFU content is educational, broad, and focused on building recognition: blog posts, social content, podcast appearances, SEO. The goal is to get in front of the right audience before they’re ready to buy, so you’re the trusted option when they are.

Touchpoint

Any interaction between a potential or existing customer and your brand — an ad impression, a website visit, a social post, an email, a phone call, a referral mention, or an in-person encounter. Mapping the full set of touchpoints across the customer journey reveals gaps, redundancies, and opportunities to improve the overall experience.

Upselling / Cross-selling

Upselling encourages a customer to purchase a higher-value version of what they’re buying. Cross-selling suggests related or complementary products or services. Both are more cost-effective than new customer acquisition because you’re selling to someone who already trusts you. For service businesses, identifying natural upsell or cross-sell opportunities within your service menu is a high-leverage revenue strategy.

Win Rate

The percentage of sales opportunities that result in a closed deal. Win rate = deals won ÷ total deals pursued × 100. Tracking win rate over time reveals whether your sales process, targeting, or competitive positioning is improving or declining. Breaking win rate down by lead source, deal size, or industry can surface which opportunities to prioritize.
