The Complete Business Terminology Guide & Startup Handbook — Everything You Need to Launch a Company

Authors

Introduction

"I want to start a business, but I have no idea where to begin."

If you have ever dreamed of launching a startup, you have probably felt this way at least once. When investors throw around acronyms like ARR and MRR in meetings, it can be overwhelming. When you search for incorporation procedures, you are bombarded with unfamiliar terms like articles of incorporation, registered agents, and capitalization tables.

This article serves two purposes:

  1. Complete Business Terminology Guide — A categorized reference of the key terms actually used in startups and business environments
  2. Full Company Formation Guide — A step-by-step walkthrough of how to actually set up a company, with a focus on general best practices and US-specific guidance

Whether you are a first-time founder or a business professional who occasionally gets confused by jargon, this guide is for you.


Part 1: Complete Business Terminology Guide

1.1 Revenue and Profitability Terms

TermFull NameDescription
ARRAnnual Recurring RevenueYearly recurring revenue. A core SaaS metric calculated as monthly subscription fee x 12
MRRMonthly Recurring RevenueMonthly recurring revenue. Tracked by segmenting into New, Expansion, and Churned MRR

Net Margin-Net Profit / Revenue x 100. Final profitability after all costs
Burn Rate-Monthly cash expenditure of a startup. Indicates how quickly funding is being consumed
Runway-Cash on hand / Monthly Burn Rate. Number of months before funds run out

Practical Tip: When meeting investors, ARR growth rate (YoY) and Burn Rate/Runway are the numbers you absolutely must have prepared.

1.2 Customer and Marketing Terms

TermFull NameDescription
CACCustomer Acquisition CostCost to acquire one customer. (Marketing + Sales costs) / New customers
LTVLifetime ValueTotal revenue a single customer generates over their entire relationship
LTV/CAC Ratio-LTV divided by CAC. A ratio of 3 or above indicates a healthy business model

PMF (Product-Market Fit)The state where a product matches market demand. The most important startup milestone
MVP (Minimum Viable Product)The simplest version of a product built to test core assumptions

2.2 Business Registration Process

Sole Proprietorship / LLC Registration

  1. Choose your state — Delaware and Wyoming are popular for LLCs; your home state is often simplest
  2. Prepare required documents
    • Articles of Organization (LLC) or DBA filing (sole proprietorship)
    • Operating Agreement (LLC)
    • EIN application (IRS Form SS-4)
  3. Register with the state — File formation documents with the Secretary of State
  4. Obtain an EIN — Apply for an Employer Identification Number through the IRS website
  5. Open a business bank account — Keep personal and business finances separate
  6. Processing time — Same day to 2 weeks depending on state

C-Corporation Registration

  1. File Certificate of Incorporation — With the Secretary of State (typically Delaware)
  2. Create corporate bylaws — Internal governance document

  4. Issue stock — File 83(b) election within 30 days if using restricted stock
  5. Register in operating states — Foreign qualification if operating outside incorporation state
  6. Ongoing requirements — Annual reports, franchise taxes, board meetings

2.3 C-Corporation Formation Details

Step 1: Pre-Formation Planning

  • Authorized shares — Typically 10,000,000 shares at 0.0001 USD par value

Step 2: Certificate of Incorporation

This is the foundational legal document for a corporation.

Key provisions:

  • Company name and registered agent
  • Authorized share capital (common and preferred stock classes)

Important: Set authorized shares significantly higher than initially issued shares to leave room for future funding rounds and employee option pools.

  • Board of directors appointment
  • Officer elections (CEO, Secretary, Treasurer)
  • Bylaws adoption
  • Stock issuance to founders (with vesting)
  • 83(b) election filing within 30 days
  • Option pool creation (typically 10-20% for early stage)

Step 4: Regulatory Compliance

  • EIN from the IRS
  • State tax registrations
  • Business licenses and permits as required
  • Qualified Small Business Stock (QSBS) eligibility tracking

Step 5: Ongoing Administration

  • Filing: Form 1120 due by the 15th day of the 4th month after fiscal year end

  • Benefits: Health insurance mandatory for companies with 50+ full-time employees (ACA requirement)
  • At-will employment: Either party can terminate the relationship at any time (with some exceptions)

2.8 Planning for Failure

Company Dissolution Process

It is wise to understand the dissolution process before you ever need it.

  1. Board and shareholder approval — Formal resolution to dissolve
  2. File dissolution documents — Certificate of Dissolution with the Secretary of State
  3. Tax clearance — File final federal and state tax returns
  4. Creditor notification — Notify known creditors and publish notice
  5. Asset distribution — Pay debts first, then distribute remaining assets to shareholders
  6. Cancel registrations — EIN, state registrations, business licenses

Personal Guarantee Warnings

Critical information every startup founder must understand:

  • Lenders often require personal guarantees from founders for company debt
  • Even with an LLC or corporation, a personal guarantee makes you personally liable
  • SBA loans typically require personal guarantees for owners with 20%+ ownership
  • Negotiate to limit guarantee amounts when possible
  • Watch for personal guarantee clauses in lease agreements and equipment financing
  • Investor agreements should generally not include personal guarantees — push back if they do

Core Principle: Avoid personal guarantees whenever possible. They eliminate the liability protection your entity structure provides.

Bouncing Back After Failure

  • Bankruptcy protection: Chapter 7 (liquidation) or Chapter 11 (reorganization) options
  • SBA resources: The Small Business Administration offers restart programs
  • Credit rebuilding: Work with credit counselors to recover
  • The value of failure: In startup ecosystems, failure experience is often viewed positively by investors
