No wait, of course THAT is the single most important SaaS metric

The single most important SaaS metric is retention, because cancellations indicate lack of product/market fit, no matter the cause (price, features, severity of need, duration of need). If it cannot be fixed, it means the business is a failure even if other metrics are stellar. Once you’re scaling (i.e. past product/market fit and into tens of millions in revenue), you realize that cancellation scales with total customers whereas growth scales with sales and marketing costs, which means cancellation necessarily and always outgrows inbound activity, thus growth ceases. So, retention is most-important, regardless of stage.

The single most important SaaS metric is top-line growth, because high revenue growth implies many other (sometimes un-measurable) things are going well, such as product/market fit, ability to get to customers, ability to retain customers, and proving the large size of the addressable market. High growth is the only way to build a large tech company, because tech market dynamics follow a “winner take all” power law, and the only way to be the biggest is to grow the fastest. Fast growth proves every other piece of the company is healthy, or at least healthy enough not to be fatal. It’s also by far the greatest determinant of equity value, because it maximizes both revenue and the revenue multiple.

The single most important SaaS metric is net profit growth, because the days where equity value is determined almost completely by top-line growth died in 2015, and now both public and private markets are rewarding not just growth, but profitable growth. Which is better anyway, because it means we’re building sustainable, value-creating companies, not just companies that grow like a virus, without purpose and possibly killing the host. The unicorns are dying not for of lack of revenue, but for lack of profit.

The single most important SaaS metric is sales efficiency, because if it’s expensive to acquire revenue, it means the product is being stuffed into the market rather than embraced by it, which means you’re artificially growing rather than having found real product/market fit and longevity. It will be too hard to grow at scale because merely replacing natural cancellation is expensive, thus your maximum size is capped. The expense means it’s too hard to be profitable in the long run, because too much of a customer’s lifetime revenue is spent in costs before they even write the first check. It means you’re “buying customers” rather than building a product people organically want, enjoy, and talk about, which in turn calls into question the fundamental value of the product.

The single most important SaaS metric is LTV, because if you look at the component metrics individually you never get a complete picture. High growth is great, but not if margins are so low there won’t be a profitable business at scale. High retention is great, but not if MRR is so low that sizable revenue requires too many customers. When you sub-optimize one number in LTV, often the others change in contrary directions. For example, you can increase price which increases MRR but also increases cancellations as people can’t afford it. Only by combining these metrics can you get a clear and true picture of the health of the business model. Some people say it’s too hard to see the future, but that’s exactly why it’s so important to try.

The single most important SaaS metric is NPS (customer satisfaction), because this is the ultimate measure of value-creation, which in turn impacts every other important metric. It impacts new growth because only high-NPS customers will participate in word-of-mouth, the least expensive form of marketing and one of the few that continues to scale with the business. It impacts retention because high-NPS implies they’ll stay. It even impacts objectively important things which don’t have numeric metrics, such as brand quality and Product relevancy. The customer is the fundamental unit of the company, and NPS measures customer health.

All of these statements are true, for some companies. The larger point is that companies are more complex than “a single most important metric.”

The purpose of a metric is to be a tool in service of your goals, timeline, size, circumstance, even philosophy, not as a master you are thoughtlessly obligated to obey.

Focussing on just one thing is indeed valuable, especially when a company is young and there isn’t enough time to cut into multiple goals. Larger companies like WP Engine can have maybe three or four, but still not many.

Your job is to figure out what’s most important right now, what’s on fire, what’s most important for getting the company to its next milestone, lean into what’s working well, and then simplify and clarify the few goals and metrics that your entire company should align on.

    Great article. The single most important metric definitely depends the business, your stage, and timing. And they definitely change. It has been interesting looking at our own dashboard as metrics rise or fade in importance. We also find that each of our teams have a different ‘most important metric’. They all funnel back to important top level goals but each team is different.

    Yeah, each company stage, there is a Most Important metric.

    And I don’t think we have right order Like:

    0 to 3 months: retention

    3 to 12 months: sales efficiency.

    12 to …

    I realy think. at the beggining if you extrapolate one of those 6, even with others not going well, you’re gonna break into the next stag.
