10 Top Metrics Investors Consider When Buying a SaaS Company

Software companies generate a tremendous amount of operational data. Dashboards grow quickly, KPIs multiply, and it can be difficult for founders to know which numbers actually matter when preparing for a sale. In a transaction environment, only a small set of metrics truly influences how investors view the durability and quality of the business. At Solen Software Group, we focus on the indicators that reflect long-term health, not the vanity metrics that can distract from real performance. These core metrics shape whether a company earns a premium valuation or faces pressure during negotiations.

1. Gross Retention Rate (GRR)

GRR measures how much recurring revenue remains from existing customers before considering any upsell. It answers a key question: if customers did not buy more, how much revenue would still be there next year. GRR above 90 percent signals product stickiness and strong renewal discipline. GRR below 80 percent raises concerns about long-term predictability. GRR is one of the clearest indicators of product market fit because it reflects real usage and real value delivered. At Solen, we look closely at GRR because it consistently predicts stability.

2. Net Revenue Retention (NRR)

NRR includes both retention and expansion. When NRR exceeds 110 percent, it shows that customers are naturally growing inside the product. NRR above 120 percent indicates exceptional value creation. This metric gives investors confidence that the company compounds organically without relying on aggressive sales spending. In our portfolio, the companies with the strongest NRR typically have clear onboarding processes, clear ROI communication, and pricing models aligned with usage.

3. Gross Margin

Gross margin shows how much profit remains after direct costs. Strong gross margins allow companies to reinvest in product, customer success, and revenue growth without relying on constant outside capital. SaaS businesses with heavy support loads or underpriced usage can experience margin pressure without realizing it. For founders preparing for a sale, understanding margin drivers and improving efficiency over time can materially influence valuation.

4. CAC Payback

CAC payback measures how long it takes to recover the cost of acquiring a new customer. Under 18 months is generally viewed as healthy in the mid-market. Payback above 24 to 30 months suggests that growth may not be sustainable. Investors now prioritize efficiency because it helps determine whether the business can scale without constant cash burn.

5. LTV to CAC Ratio

The LTV to CAC ratio compares customer lifetime value to acquisition cost. Ratios above three times indicate strong economics and room for expansion. Ratios below two times can signal challenges with churn, pricing, or acquisition efficiency. While not perfect, this ratio provides helpful context for understanding value creation.

6. Cash Metrics and EBITDA

Investors increasingly focus on EBITDA and cash conversion. Producing cash while growing demonstrates discipline and operational maturity. For founders preparing for an exit, strong cash fundamentals reinforce the message that the business can thrive long after the acquisition.

In Summary

Investors pay close attention to the metrics that reveal quality and durability. GRR, NRR, gross margin, CAC payback, LTV to CAC, and cash flow strength consistently shape how buyers evaluate a SaaS business. Founders who understand and monitor these metrics early tend to be better positioned when they enter a sale process.
