Learn how to calculate your Service Obtainable Market (SOM) and leverage it for realistic business growth

Understanding Service Obtainable Market (SOM)
Every business starts with a dream—to serve a massive audience. But how much of that audience can you realistically reach? That's where the concept of Service Obtainable Market (SOM) comes in. SOM is a critical metric that helps businesses measure the portion of their market they can actually capture. It isn’t just a theoretical number but a real guide to shaping your sales strategy and product development.
Defining SOM in Business Terms
In its simplest form, SOM refers to the share of the total market that your business can reasonably serve. It’s a subset of a larger concept known as the Serviceable Available Market (SAM), which itself is derived from the Total Addressable Market (TAM). Think of SOM as the portion of the pie that you can confidently take a bite from.
Key Components of SOM
To understand SOM, you need to focus on several key factors:
Target Market: Who are the customers you can directly serve?
Market Share: What percentage of that market is realistically within your reach, given competition and resources?
Capacity to Deliver: How much can your company produce, sell, and deliver effectively?
How SOM Fits into Market Analysis
SOM is often used by startups and businesses to create accurate forecasts, guiding how much they should invest in marketing, product development, and customer service. SOM helps to avoid setting unattainable goals by ensuring businesses focus on a realistic market size.
Importance of SOM in Strategic Planning
SOM is a key player in business planning and resource allocation. By understanding your SOM, you can plan your marketing efforts more efficiently, ensure you're targeting the right customers, and predict revenue with greater accuracy. In short, it lets you aim for the stars but keeps your feet firmly on the ground.
Differences Between TAM, SAM, and SOM
Understanding SOM fully requires knowing its relationship to TAM and SAM. Let’s break them down.
Understanding Total Addressable Market (TAM)
TAM is the grand total of everyone who could ever use your product. It’s the dream—the biggest possible market if all barriers disappeared. Think of it as the ideal, but usually unreachable, goal.
Diving Into Serviceable Available Market (SAM)
SAM is a bit more realistic. It’s the portion of TAM that your product or service can serve based on the markets you have access to. But just because you can serve them, doesn’t mean they’ll all become customers.
Service Obtainable Market (SOM) in Comparison
SOM takes it down one more notch. It’s the market you can serve and, more importantly, realistically capture. If TAM is the moon, SOM is the neighborhood store around the corner. It’s what you can get in the short term with your current resources.
How to Calculate Service Obtainable Market
Calculating SOM isn’t just guesswork. There’s a method to the madness, and it starts with clearly defining your target market and capabilities.
Steps in Identifying Your SOM
Step 1: Identifying Target Customers
First, define who you can realistically sell to, based on demographics, geography, and behavior.
Step 2: Analyzing Competitors and Market Share
Next, look at how much market share you can reasonably expect to capture, considering competition and market saturation.
Step 3: Evaluating Product or Service Capabilities
Finally, assess whether your business has the capacity to meet this demand. Can you scale up your product or service to reach your SOM?
Tools and Resources for Calculating SOM
Various software tools like market analysis platforms or CRM tools can help you estimate SOM. These tools often combine customer data, market insights, and competitive analysis to give you a clearer picture of your market size.
Why SOM Matters for Startups
SOM is a vital metric for startups because it helps prioritize efforts and avoid overestimating market size. Many startups fail because they overreach, thinking their product can dominate the entire TAM or even SAM. But SOM helps ground your strategy.
Prioritizing Resources and Efforts
By focusing on SOM, startups can direct their resources toward the most reachable customers, ensuring that marketing dollars, sales efforts, and product development are aimed at the right target.
Avoiding Overestimation of Market Potential
The allure of TAM can lead startups to overinvest in areas that won’t yield results. SOM acts as a reality check, helping companies focus on what they can actually achieve.
Real-World Examples of Service Obtainable Market
Let’s look at some examples to better understand SOM in action.
Example 1: A SaaS Company
Imagine a software company with a product for small businesses. While their TAM includes millions of businesses worldwide, their SOM might only include small companies in specific industries within a certain region that meet their price point.
Example 2: An E-commerce Business
An e-commerce startup might calculate their SOM based on the subset of customers they can serve within their shipping zones, targeting customers who are likely to convert within those areas.
Common Mistakes When Estimating SOM
SOM can be tricky to estimate, and businesses often make mistakes that skew their understanding of their market.
Overestimating Market Share
A common mistake is assuming you’ll capture too much of your SAM, ignoring factors like competition and customer loyalty.
Ignoring Competition and Barriers to Entry
Some businesses forget to factor in the impact of competition, legal restrictions, or customer resistance, leading to an overestimation of SOM.
Strategies to Grow Your SOM
Once you have a realistic SOM, the goal is to expand it over time. Here are some strategies.
Improving Customer Engagement
Focusing on customer satisfaction and retention can help you grow your market share within your SOM, turning one-time buyers into loyal customers.
Expanding into New Market Segments
As your business grows, you can expand your SOM by targeting new demographics or regions that were previously out of reach.
The Role of SOM in Business Growth
In conclusion, understanding your Service Obtainable Market (SOM) is essential for business planning. It helps you focus your efforts, make realistic forecasts, and avoid the pitfalls of overestimation. By grounding your strategy in what’s attainable, SOM ensures that your business growth is built on a solid foundation, giving you the best chance for long-term success.
Future Outlook for Market Analysis in Business Strategy
As markets evolve and new technologies emerge, SOM calculations will become even more precise, offering businesses even better tools to forecast their growth potential.
