How to Write a Market Description

July 31, 2026 Lord AI Editorial Team

A market description explains who buys, why they buy, how large the opportunity is, what alternatives exist, and what conditions shape demand. It should be specific enough to guide product, price, sales, and operations.

Replace unsupported adjectives such as “huge” or “fast-growing” with evidence and assumptions.

Quick Answer

Define the market boundary, describe target segments and buying behavior, estimate size using a transparent method, analyze competitors and trends, identify barriers, and connect the evidence to the business strategy.

Define the Market Boundary

State product or service category, geography, customer type, use case, price level, and time period. A local premium daycare market is different from the national childcare industry.

Explain what is outside the scope.

Describe Target Customers

Use needs, behavior, budget, decision process, frequency, and operating context—not demographics alone. For B2B, include industry, company size, location, systems, and buyer roles.

Distinguish user, influencer, buyer, and payer.

Explain the Customer Problem

Describe current pain, cost, risk, delay, or desired outcome. Identify current alternatives and why customers switch or remain loyal.

Use interviews, reviews, sales calls, and observed behavior.

Estimate Market Size

Define total addressable, serviceable, and obtainable market using a top-down or bottom-up method. Show formula, data source, and assumptions.

A bottom-up estimate may multiply target locations by likely customers and annual spend.

Describe Buying Behavior

Explain triggers, research channels, seasonality, sales cycle, approval, price sensitivity, switching cost, preferred delivery, and repeat frequency.

Include reasons a qualified customer does not buy.

Analyze Competition

Name direct competitors, substitutes, internal solutions, and doing nothing. Compare price, features, distribution, trust, speed, and weaknesses.

Avoid claiming there is no competition.

Identify Trends and External Factors

Discuss technology, regulation, demographics, economy, supply, culture, and channel changes that affect demand. Separate observed trends from predictions.

Explain whether the trend helps the whole category or your model specifically.

State Barriers and Risks

Include licenses, capital, contracts, customer concentration, brand trust, network effects, data, location, supply, and talent. Identify barriers that protect incumbents and risks that challenge the entrant.

Show mitigation.

Connect Market to Strategy

Explain which segment will be targeted first, the positioning, acquisition channels, pricing logic, and why the organization can compete.

A market description should lead to decisions.

Compact Example

The initial market is independent dental clinics with 3–15 chairs in Greater Toronto that outsource bookkeeping but lack weekly cash and insurance-receivable reporting. The buyer is usually the owner or practice manager. Clinics switch when month-end reports are late, adjustments are unexplained, or collections decline. The first serviceable segment is approximately 600 clinics reached through dental associations, accountants, and direct referral partnerships.

Writer’s Opinion

I would prefer a narrow, measurable market description over a large industry number. A credible path to 100 reachable customers is more useful than claiming a percentage of a billion-dollar market.

Market descriptions should be updated from sales evidence. Lost deals, conversion, price objections, and retention reveal more than static demographics.

Frequently Asked Questions

How long should a market description be?

A short business plan may use one or two pages; an investment or strategic analysis may require more detail. Include enough evidence to support decisions.

What is a target market?

It is the specific group of customers the business chooses to serve based on need, fit, accessibility, and economics.

What is TAM, SAM, and SOM?

TAM is the broad total opportunity, SAM is the portion the offer and geography can serve, and SOM is the realistic share obtainable under stated assumptions.
