High top-line revenue is a vanity metric if it doesn't translate to profit. By setting a high margin target (e.g., 80%+) and enforcing it through pricing and cost management, you ensure the business is sane and profitable, not just busy.

Judging an early-stage company on its current gross margins is a mistake. The key indicator of future profitability is its potential pricing power. A defensible, sticky product that can consistently raise prices over time is a much stronger signal than one that relies solely on falling costs.

Stripe frames unoptimized payment infrastructure not just as a missed opportunity but as an active state of "low-revenue mode." This leakage from poor conversion, authorization, and fraud prevention rates represents one of the highest ROI growth levers a company can pull, often overlooked for splashy ad campaigns.

By partnering with Uber Eats to offer restaurants free delivery, Toast directly attacks the high-fee model of competitors like DoorDash. This forces DoorDash into a dilemma: ignore a major threat or compete by cannibalizing its own high-margin core business.

High margins create stability but also invite competition. The ideal strategy is to operate with margins low enough to build customer loyalty and a competitive moat, while retaining the *ability* to raise prices when necessary. This balances long-term growth with short-term financial resilience.

For SaaS businesses that process payments, adding a fee based on Gross Merchant Value (GMV) is a powerful revenue driver. This revenue tends to grow more smoothly and predictably over time compared to spiky usage-based fees (e.g., per SMS), making it more valuable to acquirers.

While high churn is often negative, the restaurant industry's ~15% annual turnover provides a constant stream of new business opportunities. This dynamic gives a superior challenger like Toast frequent 'at-bats' to acquire customers from incumbents, a growth lever not present in low-churn industries.

Use gross margin as a quick filter for a new business idea. A low margin often indicates a lack of differentiation or true value-add. If a customer won't pay a premium, it suggests they have alternatives and you're competing in a commoditized space, facing inevitable margin compression.

Pricing is your most powerful lever. For a typical service business with a 10% net margin, a simple 10% price increase goes directly to the bottom line, effectively doubling the company's total profit without any additional operational cost or effort.
