How to Spot and Stop Revenue Leakage in B2B SaaS?


Many brands underestimate the severity of revenue leakage, a phenomenon capable of transforming a profitable business into one that incurs significant losses. The risk associated with revenue leakage is worsened by the challenge of recognizing when it occurs, and to be honest, numerous businesses lack the knowledge to address it effectively.

According to a survey conducted by Boston Consulting Group, 45% of executives perceive revenue leakage as a systematic issue within their organizations.

Within this article, we will explore the concept of revenue leakage, understand its causes, and offer guidance on how to detect and eliminate it promptly, ensuring it does not impact your business adversely.

This basic guide will comprehensively cover:

What is Revenue Leakage?

Revenue leakage refers to the inadvertent or unnoticed loss of revenue within a company, a concern that has become more pronounced with technological advancements and an expanding array of customer offerings.

Businesses facing revenue leakage may suffer losses ranging from 1 to 5 percent of their earnings, a significant impact, particularly for larger enterprises.


Here’s how you can calculate revenue leaking for your company:

Revenue Leakage = Expected Income – Income Received 

According to Baremetrics, SaaS enterprises experience approximately a 9% reduction in their monthly recurring revenue (MRR) as a result of unsuccessful payments and involuntary customer churn. Over time, this cumulative effect can lead to substantial revenue losses.

How Does Revenue Leakage Impact B2B SaaS Businesses?

Revenue leakage directly impacts the lifeblood of small and medium businesses through the cash flow. The financial health of these businesses is integral to various aspects, ranging from delivering top-notch customer service and fueling growth to fostering innovation and competing effectively for talent. Profitability hinges on a steady inflow of revenue, making the process of revenue generation a critical aspect of business operations.

For smaller enterprises, revenue is not merely a financial metric but a driving force behind their ability to celebrate milestones, such as closing significant contracts. Some companies even incorporate celebratory rituals, like sounding a gong when sealing a substantial deal, emphasizing the vital role revenue plays as the catalyst for various business activities.

While the task of collecting revenues that have been rightfully earned but inadvertently overlooked due to operational glitches may not carry the glamour of other business activities, it is a discipline that demands expertise.

Mastering revenue collection is imperative for small and medium enterprises, as failure to do so could eventually hinder their ability to realize their objectives and aspirations.

What are the Primary Causes of Revenue Leakage?

Here is why revenue leakage happens in B2B SaaS businesses primarily.

1. Billing Errors

Among the most impactful causes, issues in recurring billing processes can lead to significant revenue leakage.

Whether stemming from manual errors, such as entering incorrect totals on invoices, or automated problems like selecting wrong data for invoicing, these operational inefficiencies can accumulate into substantial losses over time. This is concerning especially when it comes to subscription renewals in B2B SaaS companies. 

2. Involuntary Churn

In SaaS businesses, involuntary churn occurs when customers are lost due to technical reasons, like payment failures.

Issues such as expired credit cards can lead to automatic cancellations, emphasizing the importance of having backup payment methods to prevent revenue leakage. Inaccurate customer data from multiple systems can also contribute to this type of churn.

3. Voluntary Churn

Voluntary churn occurs when customers intentionally end subscriptions or downgrade plans.

Addressing problems within the customer journey promptly is essential to mitigate voluntary churn and prevent associated revenue leakage.

4. Poor Communication

Inadequate internal communication, especially within sales teams, can lead to revenue leakage. If sales teams lack updated information on pricing structures or key policies, they may unintentionally charge lower rates or overlook additional invoiced costs for certain services as a result of contract mismanagement.

#TCCRecommends: Aligning communication across teams can help avoid such costly mistakes. This is why sales training is important. 

5. Misalignment Between Sales and Customer Success

Revenue leakage can occur when there is a misalignment between sales and customer success teams. For instance, if a customer expresses a need for an additional feature that could be upsold for extra revenue, miscommunication between teams may result in the customer seeking alternatives, leading to potential revenue loss.

This is why functions like RevOps exist in B2B SaaS organizations to fix such misalignments and ensure that customer churn and revenue leakage do not happen. 

6. Limited Project Visibility

Inadequate visibility into invoicing and revenue-generating processes can hinder proactive management, resulting in lost or delayed revenue. Additionally, poor project management visibility can contribute to issues such as scope creep, delayed deadlines, and inaccurate budget estimates, all of which can contribute to revenue leakage.

Inaccurate billing due to flawed methods of recording billable hours further exacerbates the problem, potentially leading to significant, unidentified revenue leakage.

How to Identify Revenue Leakage in your B2B SaaS? 

Identifying and addressing revenue leaks requires a systematic approach to pinpoint their origins. The following steps outline how to effectively identify the sources of revenue leakage:

1. Develop a Hypothesis on Leakage Sources

Companies often initially focus on their top accounts when searching for revenue leaks. While leaks may be found in prominent accounts, the most significant ones often stem from contracts with intricate terms.

Creating a hypothesis and possibilities to identify leakage sources should not solely rely on intuition but involve insights from those closely involved in revenue generation.

2. Prioritize Leaks by Economic Impact

Not all revenue leaks carry equal weight. It is prudent for companies to prioritize addressing leaks based on their economic impact. By focusing on leaks causing the most substantial financial losses, organizations can allocate resources efficiently.

For instance, if minor leaks amount to $100 each per month, but a more significant one results in a loss of $2,000 monthly, prioritizing the larger issue is paramount.

3. Verify the Hypothesis through Testing

To ensure the accuracy of identified revenue leakage sources, organizations should conduct thorough testing and verification. This can be achieved through an audit led by the finance team, collaborating with those responsible for revenue generation.

The audit should delve into data and process issues, potentially involving retracing steps related to specific revenue transactions.

6 Ways to Prevent Revenue Leakage in Your B2B SaaS

Here are some simple and effective tips to prevent revenue leakage for your B2B SaaS brand.

1. Identify the Leakage Points

Accurate diagnosis is the initial step in addressing revenue leakage. Companies should understand where revenue leaks commonly occur in their industries.

Employee feedback, especially from those in revenue-generating roles, can provide valuable insights into potential leakage points. As highlighted in the “How to Identify Revenue Leakage” section, issues may not always be in expected areas.

2. Optimize Workflows

Addressing workflow issues is crucial. Whether it’s confusing pricing structures or an organizational setup enabling excessive discounts, solutions are generally available. Even small and medium enterprises can quickly devise solutions to workflow problems.

For instance, if there’s evidence of underbilling for services, companies can implement changes like using average service times to identify potential instances of unbilled services, leading to revenue recapture.

3. Utilize Technology

Replace manual processes with effective software solutions. Technology can mitigate issues leading to revenue leaks, and numerous software programs can assist or automate manual business processes.

For example, mobile-friendly software can enable service staff to quickly submit timesheets, reducing billing errors.

Automation can also expedite invoice creation, addressing late billing or underbilling concerns.

4. Enforce Pricing Discipline

Maintain control over pricing by implementing clear and enforced rules. Salespeople with significant autonomy in offering discounts can hinder revenue maximization.

Robust enforcement of contract terms is essential, and this can be systematized through software, SOPs, and escalation matrices to ensure adherence.

5. Appoint a Revenue Assurance Individual

While not common, designating a staff member to focus on revenue assurance is crucial.

Even smaller companies without dedicated billing analysts can assign this responsibility to a senior executive, preferably from the finance department. This individual should have the authority and expertise to effectively oversee revenue assurance.

6. Centralize Timesheets

For service-oriented companies relying on billable hours, centralizing timesheets is critical.

Automated reminders through billing systems can enhance the accuracy and timeliness of information, increasing the likelihood of capturing all billable hours.
