The gross margin is a financial ratio metric, which helps assess the profitability of a business and also its operational efficiency. Indeed, as gross margins take into account the cost of goods sold (the cost incurred to deliver the software to the customer) it’s a measure to assess the value of a business.
Gross margin in a nutshell
This is the relationship between Gross Profit and sales, and it is expressed in percentage:
(Gross Profit (Revenue – CoGS) / Sales) x 100%
Imagine, company XYZ had $100K in Gross profit and $250K in Sales, for Year Two, therefore:
(100/250) * 100% = 40%
It means that 60% of your income is used to cover the cost of goods sold. This ratio is critical, since for many organizations, in particular, manufacturing, most of the costs are associated with CoGS (Cost of Goods Sold).
For example, if you have to produce an Ice cream, you have to buy raw materials to make it. Also, someone has to “assemble” the Ice cream before it can be sold.
Well, the raw materials and the work needed to produce the final product are considered CoGS. In other words, those are the costs required before the Ice cream can be sold.
Therefore, this measure can be beneficial to assess the operational profitability of the business.
Why gross margins matter
David George and Alex Immerman, partners at the venture capital firm a16z highlighted, “A high gross margin is a preferred business feature. Higher gross margins allow for more percentage points of revenue to be spent on growth and product development.”
This is a critical element to understand, as software companies, while usually carrying higher gross margins than traditional organizations are more focused on physical infrastructure.
Those same software companies’ products also might become outdated quickly, as technology evolves.
In addition, in order to distribute software and enable its continuous growth, it requires massive investments in marketing and sales.
For instance, Salesforce, among the most valuable software companies, in terms of market cap, in 2020 spent more than 46% of its revenues on sales and marketing.
Compared to 25% in total for the cost of goods sold, and 16% for product research and development (FourWeekMBA Analysis).
As David George and Alex Immerman, further pointed out “higher gross margins also tend to translate to higher cash flow margin, and in a world where ‘how much runway do you have’ has become an (if not, the) preeminent question, cash is paramount. For these reasons, high gross margin companies typically have higher revenue multiples than their low gross margin counterparts.“
Less risk aversion more gross margins
As Fred Wilson, from AVC, pointed out in “The Great Public Market Reckoning,”
If you look at the class of companies that have come public in the last twelve months, many of the stocks that have performed the best are software companies with software margins. One notable exception to that is Beyond Meat.
He mentioned examples like Zoom, Cloudfare, and Datadog. Where other companies, like Uber, Lyft and Peloton were losing value.
In short, he pointed out how in times when investors are more risk averse gross margins become secondary.
However, where there is more market risk aversion, gross margins become extremely important.
Gross margins vs. moats
David George and Alex Immerman also point out how looking at gross margins alone are misleading, as it makes you forget what really drives business value.
As they further point out “business quality is about defensibility. Defensibility comes from moats.”
In short, if a company is focusing on higher gross margins at the expense of business defensibility that might over time translate into a
loss of competitiveness of the business.
As they point out, companies like Apple, Walmart, Netflix, and others, have much lower margins compared to software companies, and yet, those are among the most valuable brands in the world.
But what makes up a moat? There are several ways to build moats and some of them are:
Economies of scale

Which enables companies to improve efficiency and profitability as the company scales (beware though of diseconomies of scale).
Differentiated technology
In a software world where hundreds of new products are launched to the market every day, building up differentiation (in terms of features, technology, and value proposition) is a key element.
Network effects

This is true for platform business models.
Where in economies of scale the company gains in efficiency and profitability as it grows (it lowers its per cost unit).
In network effects, the platform becomes more valuable as its per-user value grows as more users join (beware of negative or reverse network effects).
Direct brand
One of the most powerful business defenses is the brand or the direct access to your customer base.
For instance, if you take Facebook, it’s still among the most valuable websites on earth, because people recognize its brand.
There is no intermediary, people access their Facebook app, or go directly to the Facebook login page.
This is critical, as over time it defends against disintermediation.
If let’s say, Facebook depended solely on traffic coming from Google, the day Google had launched its social network, it would have killed Facebook.
Yet, as the product and brand were recognized and people got straight to the source, it didn’t need any intermediary.
Distribution

Strong products and brands can draw directly from their user or customer base.
Having a strong distribution network is also a key element. As highlighted in the Google TAC and if we look at the costs associated with the money invested into the distribution of some of the most valuable brands, this goes in the multi-billion dollar mark.

Value proposition and perception

Understand what’s the killer use case that makes your product value in the hands of several types of customers is another key ingredient.
While this might go beyond the engineering world, and as such it might seem foggier, it is though one of those elements that make a long-term difference.
In short, are you willing to test, and experiment with your product to find value propositions that fit the market?
If so, your product will evolve contextually, to create moats.
Those factors combined are all part of your business model recipe, and it often becomes evident only in hindsight.
And it takes years to build. What’s left is a lot of business experimentation, and a strong long-term vision.
