For SaaS companies, variable costs are expenses that change in proportion to business activity, user base, or sales volume. Think customer onboarding, cloud hosting, third-party API costs, and transaction fees, among other costs.
Understanding and managing these costs is crucial as they directly impact the scalability and profitability of a SaaS company.
Why are variable costs difficult to manage?
SaaS businesses face unique challenges when streamlining variable costs because, unlike traditional software companies or businesses, SaaS companies continually deliver and maintain their products/services. It is not a ‘once-and-done’ deal.
This results in ongoing operational expenses that fluctuate based on usage and demand, making financial planning more complex.
- Scalability issues: As the number of users increases, the infrastructure needed to support them grows as well. This is usually a non-linear cost increase, where doubling users might more than double the costs. Given the nature of SaaS, different types of users may have vastly different consumption patterns, making it difficult to predict costs with precision.
- Pricing model complexity: SaaS companies usually have complex pricing strategies like per-user or usage-based pricing models. There are also multiple tiers in some cases. Per-user models are simpler, but they may not accurately reflect costs. Usage-based models are more accurate but can be confusing for customers. If the company has a tiered pricing structure, it adds another layer of complexity, as companies must now determine where to set tier boundaries and what features to include at each level.
- Dependency on service providers: SaaS companies are heavily dependent on various service providers to run their products. Change in the service providers’ pricing impacts variable costs. Switching costs between providers can be high in terms of direct costs and potential service disruptions, making it difficult to change providers.
- Demand volatility: SaaS companies often have fluctuations in demand due to seasonality or spikes due to factors like marketing campaigns, regulatory aspects, etc. These growth or sudden spikes in usage also lead to increased variable costs.
- Cost Allocation: Multi-product SaaS companies find it difficult to accurately attribute shared infrastructure costs to different products. This means that the company cannot accurately determine the ‘true’ cost of serving individual customers. To add to the complexity, there are varying levels of support and customization.
How can you make variable costs more predictable?
- Comprehensive variable cost forecasting: When creating budgets or projecting growth, consider all associated variable cost increases, such as cloud storage and third-party API calls. Negotiating long-term contracts with vendors can often result in significant discounts. For example, if you expect to double your customer base, factor in not just the direct increase in resource usage but also potential volume discounts you could possibly get from vendors. This approach helps prevent unexpected cost spikes and identifies opportunities for economies of scale.
- Historical analysis of variable cost patterns: Historical analysis of variable cost patterns can help SaaS companies optimize their expenses. This involves examining past data closely to uncover trends, inefficiencies, and opportunities for cost reduction. By regularly reviewing resource utilization, companies can identify usage patterns that drive costs and make informed decisions to optimize their operations.
- Variable cost scenario planning: Use what-if analyses to anticipate how changes in user behavior or business operations could affect variable costs. One can ideally model scenarios such as sudden user growth, changes in vendor pricing, feature usage, etc. This exercise allows you to prepare for fluctuations in variable expenses and make informed decisions about resource allocation.
- Adaptive variable cost monitoring: SaaS companies can tailor their cost monitoring frequency to match the volatility of specific variable expenses. One could potentially consider real-time monitoring for highly elastic costs like cloud computing resources, monthly reviews for variable costs like API calls, and quarterly analyses for other comparatively slower-changing variable expenses. This tiered approach could ensure better management of variable costs while maintaining a long-term perspective on overall cost trends.
How can technology help manage variable costs better?
The use of advanced business budgeting software can be particularly effective for SaaS companies.
Business budgeting software offers comprehensive financial management capabilities, including detailed expense tracking and analysis, automated real-time adjustments, seamless integration with related business software, and advanced predictive algorithms.
Furthermore, companies can also customize their dashboards to visualize their cost structures in real time. With scenario planning, financial teams can model various possible trajectories and examine their associated cost implications.
These features collectively enable SaaS businesses to gain clear insights into the impact of variable costs on their financial health and enable them to effectively plan for future expenses while mitigating financial risks through data-driven forecasting.
