55 Must-Know Business Terms
1. KPI (Key Performance Indicator)
A KPI is a number that shows whether something important is going well. For example, a store might use daily sales as a KPI to see if a promotion works.
KPIs should be measurable, tied to a goal, and checked regularly so teams know whether they’re on track.
2. ROI (Return on Investment)
ROI tells you how much money you made (or lost) compared to what you spent. If you spent $100 on an ad campaign and got $300 in profit, your ROI is positive. Businesses use ROI to decide which projects are worth investing in.
3. EBITDA
This stands for earnings before interest, taxes, depreciation, and amortization. It’s a rough way to see how much money a company makes from its normal operations, ignoring financing and accounting details. Investors use it to compare companies more fairly.
4. Burn rate
Burn rate is how fast a company spends cash, usually measured per month. Startups watch burn rate to know how long they can keep running without new money. If you spend $50,000 a month and have $500,000, your runway is ten months (see runway).
5. Runway
Runway is how long a business can keep going at its current spending rate before it runs out of cash. It’s important for startups that aren’t yet profitable. Longer runway gives you more time to find customers, raise money, or cut costs.
6. Pivot
A pivot is a big change in a company’s product, strategy, or business model after learning something new. For example, a company may start selling directly to customers, then pivot to serving other businesses if that proves more profitable.
7. MVP (Minimum Viable Product)
An MVP is the simplest version of a product that still delivers value. It’s built quickly so real users can test it. The goal is to learn what works and what doesn’t without spending a lot of time or money.
8. CAC (Customer Acquisition Cost)
CAC is the average amount you spend to get one new customer. It includes marketing, sales time, and any promos used to close the sale. Keeping CAC low while keeping customers happy is key to profitable growth.
9. LTV / CLTV (Customer Lifetime Value)
LTV is the total money a customer is expected to bring in over the whole time they use your product or service. If LTV is much higher than CAC, your business model is usually healthy. It helps decide how much to spend on acquiring customers.
10. Churn rate
Churn rate is how many customers leave over a certain period. High churn means customers aren’t sticking around, which can ruin growth. Reducing churn (improving product, service, or pricing) is often more profitable than acquiring new customers.
11. Conversion rate
Conversion rate is the percentage of people who take the action you want, like buying, signing up, or downloading. If 100 people visit a page and 5 buy, the conversion rate is 5%. Small improvements in conversion can greatly boost revenue.
12. Funnel (sales/marketing funnel)
A funnel describes the steps people go through from first hearing about you to becoming a customer. At the top you have many prospects; at the bottom you have buyers. Understanding the funnel helps you fix where prospects drop out.
13. Freemium
Freemium is a business model that offers a basic product for free and charges for advanced features. It helps attract lots of users quickly; a small percentage converts to paying customers. It works best when paid features add clear extra value.
14. SaaS (Software as a Service)
SaaS describes software you use online and pay for regularly, usually by subscription. Instead of installing software on individual machines, companies host it in the cloud. This makes updates and scaling easier.
15. Bootstrapping
Bootstrapping means building a business with little or no outside funding, using revenue and savings. It forces focus on profitability and cost control. Founders who bootstrap retain more ownership but may grow more slowly.

Popular Business Terms Every Business Person Should Know
16. Unicorn
A unicorn is a private startup valued at $1 billion or more. The term signals fast growth and high investor expectations. Unicorn status is rare and often brings media attention, but it doesn’t guarantee long-term success.
17. Seed funding
Seed funding is the first outside money a startup raises to build its product and prove the idea. It’s usually a small amount compared to later rounds and comes from angel investors, friends, or early-stage venture funds.
18. Series A / B / C
These are stages of venture capital investment as a company grows. Series A is for scaling an early product, Series B for expanding market share, and Series C+ for large-scale growth or preparing for an exit like an IPO or acquisition.
19. Angel investor
An angel is an individual who invests personal money in a startup, often very early on. Angels may also give advice and connections. Their investments are riskier but can yield high returns if a startup succeeds.
20. Venture capital (VC)
Venture capital comes from firms that pool money to invest in startups with high growth potential. VCs expect big returns and usually take equity. They also help with strategy, hiring, and introductions.
21. CapEx (Capital Expenditure)
CapEx are one-time or infrequent purchases for long-term use, like buildings, machinery, or software licenses. These costs are capitalized on the balance sheet and depreciated over time rather than expensed immediately.
22. OpEx (Operating Expenditure)
OpEx covers day-to-day costs like rent, salaries, utilities, and supplies. Unlike CapEx, these costs are expensed right away. Managing OpEx efficiently helps improve short-term profitability and cash flow.
23. Due diligence
Due diligence is the careful check done before a big deal, like buying a company or investing. It looks at finances, contracts, operations, and risks so buyers or investors know exactly what they’re getting into.
24. Scalability
Scalability is how well a business can grow sales without costs rising faster than revenue. A scalable business can add customers cheaply—often through software or repeatable systems, so profits increase as it grows.
25. Leverage
Leverage means using borrowed money or other people’s resources to try to increase returns. It can speed growth but also raises risk: if things go wrong, debt magnifies losses. Use leverage carefully and with a plan.
26. Value proposition
Your value proposition is the clear reason someone should choose your product or service. It explains the main benefit, who it’s for, and how it’s different from alternatives.
A strong value proposition answers “why us?” quickly and helps marketing and sales focus on the message that actually matters to customers.
27. Core competency
A core competency is something your company does especially well and that others find hard to copy. It could be a technical skill, a unique process, or deep customer knowledge.
Identifying core competencies helps leaders decide where to invest and what to protect as competitive advantage.
28. Go-to-market (GTM) strategy
A go-to-market strategy is your plan to bring a product to customers and get it selling. It covers target customers, pricing, channels (online, retail, partners), and launch tactics.
A clear GTM helps coordinate marketing, sales, and product teams so the launch delivers predictable results.
29. Product–market fit
Product–market fit means your product solves a real problem for enough people who are willing to pay for it. You feel it when growth becomes easier: referrals, low churn, and rising demand.
Finding product–market fit should come before big spending on growth or hiring.
30. Stakeholder
A stakeholder is anyone who has an interest in or is affected by your business: customers, employees, investors, suppliers, even local communities.
Thinking in terms of stakeholders helps you balance different needs and avoid decisions that benefit one group while hurting others.
Must-Know Business Slang Terms
31. Deliverable
A deliverable is a specific output you must produce in a project: a report, a prototype, a marketing plan.
It should be clear who is responsible and what “done” looks like. Well-defined deliverables reduce confusion and help teams track progress toward milestones.
32. Action item
An action item is a small task assigned to someone to move work forward, often after a meeting. It should include what to do, who will do it, and a deadline. Using action items prevents conversations from staying theoretical and ensures follow-through.
33. Backlog
A backlog is the prioritized list of work that needs doing, commonly used by product and development teams. Items at the top are next-in-line; items at the bottom can wait.
Managing the backlog keeps teams focused on the highest-impact work and prevents random task-jumping.
34. Touch base
To “touch base” means to check in briefly; to update, confirm, or sync with a colleague. It’s a casual, flexible phrase used for short status conversations that don’t need formal meetings. It signals informal, quick communication rather than deep problem-solving.
35. Circle back
Circle back means to return to a topic later when more information is available. It’s useful in meetings when an issue needs research or a decision must wait. Be specific when you circle back: say when you’ll return and what you’ll bring.
36. Bandwidth (in business speak)
Bandwidth refers to a person’s capacity to take on more work. Saying “I don’t have bandwidth” means someone is already busy. It’s a polite way to set boundaries and helps prioritize tasks realistically across the team.
37. Low-hanging fruit
Low-hanging fruit are easy wins that require little effort but give a good return. They’re great early targets for teams that need quick momentum. While tempting, don’t focus only on them; balance quick wins with strategic work that builds long-term value.
38. Take it offline
Take it offline tells people to move a discussion out of the current meeting into a separate conversation. Use it to keep meetings on schedule and handle details with the relevant stakeholders later. Always note who will lead the offline follow-up.
39. Move the needle
To “move the needle” means to do something that creates a meaningful, measurable change in results. Small tasks don’t move the needle; strategic initiatives do. Use this phrase when prioritizing work that will materially affect KPIs or business outcomes.
40. Buy-in
Buy-in is the support or approval you need from stakeholders to move forward. Without buy-in, even good plans stall. Getting buy-in often requires clear communication of benefits, addressing concerns, and sometimes small compromises.
41. Onboarding
Onboarding is the process of welcoming and training new employees or customers so they become productive and successful.
For employees, it includes introductions, tools, and clear first tasks. For customers, onboarding focuses on setup, guidance, and early value so they stick around.
42. Offboarding
Offboarding is the formal process when someone leaves—an employee or a partner. It includes knowledge transfer, account access removal, exit interviews, and handover documentation. Proper offboarding protects the company and preserves institutional knowledge.
43. PoC (Proof of Concept)
A PoC is a small test that shows whether an idea or technology will work in practice. It’s less than a pilot and focused mainly on feasibility. PoCs are useful to de-risk big projects before investing heavily in development or rollout.
44. Pilot
A pilot is a limited, controlled rollout of a product or service to test how it performs in the real world. Pilots help teams learn about customers, identify problems, and refine the offering before a full launch. Successful pilots reduce the risk of large-scale failures.

45. Run rate
Run rate takes short-term performance (monthly or quarterly revenue) and projects it forward to estimate annual figures. It’s a quick, rough forecast useful for planning, but it assumes no big changes and can be misleading if the business is seasonal or rapidly changing.
46. OKR (Objectives and Key Results)
OKRs are a goal-setting method where an Objective states what you want to achieve and Key Results show measurable success. Objectives are inspirational; Key Results are specific and quantifiable. OKRs align teams and make progress visible without dictating how work is done.
47. CRM (Customer Relationship Management)
CRM refers to systems and practices for managing interactions with customers and prospects. A CRM stores contact details, tracks deals, and records communications so teams can deliver better service and close more sales.
Good CRM discipline prevents leads from slipping through the cracks.
48. NPS (Net Promoter Score)
NPS is a simple metric that asks customers how likely they are to recommend you on a scale of 0–10. Scores divide customers into promoters, passives, and detractors.
NPS helps measure loyalty and predicts growth potential; companies use it to spot service and product issues.
49. SWOT analysis
SWOT stands for Strengths, Weaknesses, Opportunities, and Threats. It’s a simple framework to analyze the current situation and plan strategy.
Strengths and weaknesses are internal; opportunities and threats come from the outside. Use SWOT to focus on realistic, actionable priorities.
50. Silo (organizational silo)
A silo happens when teams hoard information and don’t collaborate, blocking cross-functional work. Silos lead to duplicated effort, missed opportunities, and slow decision-making.
Breaking down silos often needs leadership, shared goals, and deliberate communication channels.
51. Pain point
A pain point is a specific problem your customer or internal team faces. Understanding pain points is the starting point for product design and marketing. Solutions that directly address real pain points are easier to sell and more likely to keep customers.
52. Benchmarking
Benchmarking is comparing your processes, performance, or metrics against industry leaders or competitors. It helps you spot gaps and set realistic improvement targets. Don’t benchmark blindly; adapt insights to fit your context and capability.
53. Proof point
A proof point is concrete evidence: data, case studies, or testimonials; that supports a claim about your product. Proof points build trust in marketing and sales by backing up promises with facts customers can verify.
54. Go big or go home (buzz phrase)
This phrase encourages bold, ambitious action rather than timid efforts. It’s a cultural nudge toward high-impact goals, but it can be risky if used without strategy. Balance big bets with careful testing and contingency plans.
55. Back-of-the-envelope
A back-of-the-envelope calculation is a quick, rough estimate you do without detailed data. It’s useful for early decisions and sanity checks, but it’s not a substitute for a full analysis. Use it to decide if an idea is worth further investigation.

FAQs
A KPI is a steady metric you monitor to see if something is performing (e.g., monthly sales). An OKR is a goal (Objective) plus measurable steps (Key Results) that push change; OKRs are often time-bound and stretch targets, while KPIs are ongoing measures.
Pick a small set (3–5) tied directly to your business objective; revenue, retention, or growth. Prefer metrics that are measurable, influenceable by your team, and predictive of the outcome you care about.
Look for clear signs: steady user growth, low churn, organic referrals, and customers who pay without heavy discounts. If users consistently use the product and recommend it, you’re likely at or near product–market fit.
Both matter, but early-stage focus usually goes to lowering CAC enough to allow sustainable experimentation, then optimize LTV for scale. A simple rule: if LTV is meaningfully higher than CAC, you have room to grow; if not, fix acquisition or retention first.
Start by identifying why customers leave (surveys, support tickets, usage data). Prioritize fixes that improve onboarding and core value delivery, then test targeted retention tactics (personalized outreach, product tweaks, pricing adjustments) and measure impact.
