How to Manage SaaS Costs: Stop the Invisible Money Leak

What is Cost Management in SaaS?

Cost management in SaaS isn’t just about eliminating obvious waste like unused subscriptions or unnecessary spending on flashy company perks that don’t generate revenue.

True cost management means making strategic choices about where to put money. The goal is to maximize cash flow—because with strong cash flow, you can either grow revenue through reinvestment or avoid bankruptcy during a cash crunch. Sometimes those choices even increase costs because you have to spend money to generate more cash flow.

To do that effectively, first you have to understand the relationship between spending and revenue. This is called cost structure. This includes which costs will increase sales by how much, and which costs stay the same even when sales increase.

SaaS businesses are fundamentally labor-intensive operations, imagine a sweatshop. This means effective cost management in SaaS is primarily about managing people efficiently.

Marketing and Sales Cost Management

Your other major expenses are marketing and sales, which you’re probably already tracking through Customer Acquisition Cost (CAC) calculations. Effective management requires detailed tracking:

  • Which ads generate how many leads
  • What percentage of leads convert to paying customers
  • How long the conversion process takes
  • When customers leave, identify which marketing channel and which specific ads originally brought them in

This detailed tracking is essential for optimizing marketing spend. The same level of tracking should apply to sales representative performance.

The Two Components of People Management

There are two types of people management that are both essential for success:

1. Time Spending Management

This involves measuring how employees spend their time. By tracking which products, tiers, and features they work on, you can calculate the actual cost of each by simply dividing salary by time allocation.

For example, if you pay developer Tekahashi a $3,000 monthly salary and he spends 300 hours on Product A, 200 hours on Product B, and 100 hours on Product C, the labor cost allocation would be:

  • Product A: $1,500 ($3,000 × 300h ÷ 600h total)
  • Product B: $1,000 ($3,000 × 200h ÷ 600h total)
  • Product C: $500 ($3,000 × 100h ÷ 600h total)

This is the foundation of labor cost management. And track every employee’s time. By doing this, you can see which products, tiers, and features actually generate profit, since if you don’t know costs, you can’t calculate the profit. This allows you to focus your investments on the highest return area. As I said, true cost management isn’t just about cutting expenses – it’s about strategically allocating resources where they’ll generate the best returns.

Elements to track time spent on include:

  1. Which product (Product A, Product B, etc.)
  2. Which customer tier (SMB, Mid-sized, Enterprise, or “General” when applicable)
  3. Which specific feature (or “General” for non-feature-specific work)

All employees—from customer success to developers, sales representatives, and marketers—should record this information in their time tracking. With this data, you can decide where to focus resources, create more accurate budgets, forecast cash flow precisely, and understand development timelines better.

Implementation requires a time-tracking system that lets employees categorize their work by product, tier, and feature, with easy-to-access summary reports.

2. KPI Management

Every employee, not just sales representatives, must have clear Key Performance Indicators (KPIs). These fall into two categories:

  • Process-based KPIs: Measure activities, such as how many calls a customer success representative makes to at-risk customers
  • Result-based KPIs: Measure outcomes, such as a customer success representative reducing churn rate by at least 3%

Without KPIs, you cannot objectively evaluate employee value. Paying high salaries to employees who seem busy but produce little actual value wastes resources.

When hiring, communicate terms clearly—especially bonuses—and make it clear they depend on meeting KPIs. This creates a fair system for determining salary based on actual contribution.

Conclusion

Effective SaaS cost management starts with measuring employee time accurately.  Start tracking immediately. You can’t manage what you can’t measure. By implementing detailed time tracking and clear KPIs, you’ll gain visibility into your true costs and make better strategic decisions.

Next Steps for Implementation

  1. Select a user-friendly time tracking system that won’t become a burden
  2. Define clear categories for products, tiers, and features
  3. Train employees on proper time recording
  4. Establish meaningful KPIs for each role that align with business objectives
  5. Review data regularly and adjust your strategy based on insights
  6. Remember that the goal isn’t just cost-cutting but optimizing resources for maximum value

With these practices in place, you’ll transform your SaaS business from suffering invisible money leaks to achieving strategic cost efficiency that drives sustainable growth.
