If you have ever looked at your revenue graph and thought, “We’re growing, but it still feels fragile,” gross margin is usually the reason. You can be signing customers, shipping product, even raising money, and still be quietly leaking value with every sale. Many early founders only realize this when an investor asks a simple question they cannot confidently answer: What happens to your margins as you scale?
To put this guide together, we reviewed founder letters, finance deep dives, and interviews from operators who built durable businesses, not just fast-growing ones. We paid special attention to how leaders like Jeff Bezos, Patrick Campbell, and Brad Jacobs talked about margins in their own words, then cross-checked those philosophies against how their companies actually performed over time. The goal was to separate slogans from practices and translate what works into decisions you can make this quarter.
In this article, we will define gross margin in plain English, explain why it matters so much for early-stage founders, and walk through concrete ways to improve it without sabotaging growth.
What Gross Margin Actually Is
Gross margin is the percentage of revenue you keep after paying the direct costs required to deliver your product or service.
In formula form:
Gross Margin = (Revenue − Cost of Goods Sold) ÷ Revenue
Cost of goods sold, or COGS, includes only costs that scale directly with usage or sales. For a SaaS company, that usually means hosting, third-party APIs, and customer support tied to usage. For an eCommerce business, it is inventory, manufacturing, shipping, and payment processing. For services, it is billable labor.
Gross margin answers a simple but brutal question: Does every additional dollar of revenue make your business stronger, or just busier?
A 20 percent gross margin means you keep 20 cents of every dollar before paying for marketing, product development, and salaries. An 80 percent margin means you keep 80 cents. That difference determines how forgiving your business will be when something goes wrong.
Why Gross Margin Matters More Than Revenue Early On
Early-stage founders are often told to focus on growth first and margins later. That advice is context-dependent and frequently misunderstood.
Jeff Bezos repeatedly emphasized in Amazon shareholder letters that long-term value comes from structural advantages, not short-term profits. What often gets missed is that Amazon was obsessive about unit economics even while reinvesting heavily. The company was willing to sacrifice margin temporarily, but only when it believed scale would eventually improve it.
For you, gross margin matters now for three reasons.
First, it determines how much room you have to experiment. Higher margins give you more runway per dollar of revenue. You can afford mistakes, retries, and longer learning cycles.
Second, it shapes what kind of company you can become. Low-margin businesses must rely on volume, efficiency, or leverage. High-margin businesses can win through focus, product quality, or brand.
Third, investors care deeply about it. Even at seed stage, experienced investors use gross margin as a proxy for pricing power and defensibility. A weak margin is a signal that competition or cost pressure may eventually crush you.
What Is a “Good” Gross Margin?
There is no universal target, but there are strong norms by business model.
SaaS companies often aim for 70 to 85 percent gross margins at scale. Many start lower, in the 50s or 60s, because of inefficient infrastructure or heavy support costs early on.
eCommerce brands typically operate between 30 and 60 percent, depending on category and fulfillment complexity.
Services businesses often land between 40 and 70 percent, depending on how specialized the labor is and how well utilization is managed.
What matters most is not where you are today, but the direction your margin moves as you grow. A margin that improves with scale is a tailwind. One that degrades is a warning sign.
The Most Common Gross Margin Traps for Founders
Before talking about improvement, it is worth calling out where margins quietly get destroyed.
One trap is underpricing to win early customers. Patrick Campbell, former CEO of ProfitWell, has explained in multiple talks that founders consistently underestimate customers’ willingness to pay, then lock themselves into pricing that is painful to unwind later. The outcome is growth that feels good but never compounds into real profitability.
Another trap is bundling too much cost into the core product. Free onboarding, white-glove support, or custom work can help close early deals, but if those costs scale linearly with customers, your margin ceiling gets capped early.
A third trap is confusing gross margin with contribution margin. Marketing spend, sales commissions, and R&D do not belong in gross margin. When founders mix these together, they either panic unnecessarily or miss real problems hiding in COGS.
How Gross Margin Improves Sustainably
Sustainable improvement means raising margins without eroding customer value or killing growth. That usually comes from structural changes, not one-off cost cutting.
1. Price Based on Value, Not Fear
The fastest way to improve gross margin is pricing, but also the hardest emotionally.
Value-based pricing means anchoring your price to the outcome you create, not your internal costs. Patrick Campbell often pointed out that customers do not care what your AWS bill is. They care what problem disappears when they use your product.
For early founders, this usually starts with segmentation. Identify your most valuable customers and understand what success looks like for them in concrete terms, hours saved, revenue unlocked, risk avoided. Pricing that reflects that value can increase margins overnight, without adding cost.
The sustainable part is pairing higher prices with clear positioning and outcomes, not surprise increases or hidden fees.
2. Attack the Biggest Cost Driver First
Not all COGS are equal. One line item usually dominates.
For SaaS, it might be infrastructure inefficiency. Early teams often overprovision or rely on expensive third-party services before optimizing. As scale increases, re-architecting can materially lift margins.
For eCommerce, it is often fulfillment and returns. Improving packaging, reducing damage, or tightening return policies can move margins more than negotiating pennies with suppliers.
The key is to focus on structural fixes, not shaving everything by 5 percent. One meaningful change beats ten minor ones.
3. Design for Self-Service Early
Every manual step in delivery is a margin tax.
Founders like Des Traynor at Intercom have described how early customer conversations revealed which parts of onboarding and support could be productized. Each workflow moved from human to self-serve increased margin and consistency at the same time.
For your business, ask which recurring support questions, setup steps, or exceptions could be eliminated with better defaults, documentation, or product design. This is margin improvement that also improves user experience.
4. Separate Experiments From the Core
It is fine to run low-margin experiments. It is dangerous to let them become the default.
Custom deals, pilots, or services can teach you a lot early on. The mistake is failing to draw a hard line between learning mode and scale mode. Sustainable margin improvement requires deciding which offers are strategic and which are temporary.
Clear internal accounting helps. Track experimental revenue separately so you do not misread your true gross margin.
5. Renegotiate With Leverage, Not Hope
As volume grows, your leverage with vendors improves. Many founders never revisit early contracts, even after usage multiples higher.
This is where scale should help margin. Renegotiating hosting, shipping, or tooling costs once you have data and alternatives can unlock meaningful gains. The sustainable part is making this a habit, not a one-time scramble when cash gets tight.
How to Tell if Your Margin Is Actually Healthy
A healthy gross margin does three things.
It stays stable or improves as revenue grows.
It supports your go-to-market motion without heroic efficiency.
It leaves room to invest in product and brand without constant tradeoffs.
If improving margin requires cutting things customers love, that is usually a sign pricing or positioning is off. If it requires eliminating waste customers never see, you are on the right path.
Do This Week
- Calculate your gross margin correctly, separating COGS from operating expenses.
- Identify the single largest cost inside COGS and write down why it exists.
- Review your pricing against customer outcomes, not competitors.
- Segment customers by value and compare margins across segments.
- List any manual steps that scale with customers and flag one to automate.
- Separate experimental or custom revenue from core revenue in your reporting.
- Pull your largest vendor contracts and note renewal or renegotiation dates.
- Write a one-page memo answering: “What happens to margin if we double revenue?”
Final Thoughts
Gross margin is not about being cheap or greedy. It is about building a business that gets stronger with every customer instead of more fragile. Many founders postpone this thinking because it feels abstract or premature. In reality, margin discipline is what buys you time, confidence, and options.
You do not need perfect margins today. You need a clear path to better ones tomorrow. Start by understanding where your dollars really go, then make one structural change that future you will be grateful for.
