Increasing revenue does not necessarily mean that the revenue funnel is healthy. A business may continuously generate potential customers while its conversion rate declines. The Sales team may have many opportunities, but most of them remain in the Pipeline for too long. Revenue may still meet the target, while the time from receiving a customer to closing a deal continues to increase.
These issues do not usually appear immediately in the final revenue figures. They lie within smaller steps of the sales journey and only become clear when the business starts looking at the entire revenue funnel as a system.
For a CEO, it is not enough to know how much the business sold this month. It is important to understand where that revenue came from, how opportunities are converting and at which stage the business is losing opportunities.
That is also why the revenue funnel needs to be given a regular “health check.”
Not to create more reports, but to identify the points that are slowing down the process of converting potential customers into actual revenue.

5 Metrics CEOs Should Look at When Checking the Revenue Funnel
1. Number of Opportunities at Each Stage
Start by looking at how opportunities are distributed throughout the entire Pipeline.
A typical Pipeline moves through multiple stages, from the moment a new customer is received, to the beginning of consultation, receiving a quotation and eventually reaching the final decision. The number of opportunities at each stage gives the CEO an initial picture of the sales flow.
For example, a business may have 500 potential customers, but only 80 opportunities are actually being consulted and 15 opportunities have reached the negotiation stage. This indicates that a large portion of opportunities have not moved deeply into the sales process.
Conversely, if hundreds of opportunities are concentrated at the consultation stage but very few move to quotation, this may be a sign that requires further investigation.
It is important not to assume that having many opportunities at one stage is necessarily a good thing. A Pipeline with too many stagnant opportunities can create the impression that the business has a large amount of potential revenue, while in reality, its conversion potential may be low.
CEOs should look at the distribution and movement of opportunities, rather than simply looking at the total number.
An important question to ask is: Are opportunities moving through the Pipeline, or are they getting stuck at a certain point?
2. Conversion Rate Between Stages
If the number of opportunities tells us “how many opportunities are here,” the conversion rate tells the CEO how many opportunities are actually moving forward.
For example, out of 100 potential customers, 60 are contacted by Sales, 40 receive a consultation, 20 receive a quotation and 8 eventually complete a transaction. By looking at each step, the business can identify where the conversion rate drops significantly.

Suppose the conversion rate from potential customer to consultation is relatively good but drops significantly from consultation to quotation. In that case, instead of immediately asking Sales to find more customers, the business should examine the consultation stage.
Are the customers actually a good fit? Has Sales identified their needs correctly? Is there a missing step in the consultation process? Or are the criteria for moving an opportunity to the quotation stage unclear?
Conversion rate is therefore not simply a number for evaluating Sales performance. It is a tool that helps the business identify where it needs to ask questions.
In particular, CEOs should not look at a single conversion rate in isolation. Conversion rates should be compared across stages, customer sources, products or time periods to identify trends.
A decline in one month is not necessarily a problem. But if the same stage continues to have a low conversion rate for several months, that is a signal the business should examine more closely.
3. How Long Opportunities Stay in the Pipeline
A sales opportunity does not only have a status. It also has an age.
Two opportunities may both be at the “Quotation” stage, but one may have been updated yesterday while the other has been sitting there for 45 days. If you only look at their status, these two opportunities may appear similar. But in terms of their ability to generate revenue, they may be completely different.
Therefore, CEOs should track the average amount of time an opportunity needs to move from one stage to the next.
If many opportunities continuously remain at the same stage longer than usual, the business needs to understand why.
Perhaps the customer needs more time to make a decision. It could also be that Sales does not have an appropriate follow up step, internal approval is taking too long or the opportunity is no longer realistically convertible but its status has not been updated.
This metric is particularly important for revenue forecasting. A Pipeline with many opportunities that have already existed for too long does not have the same forecasting value as a Pipeline where opportunities are continuously moving forward.
In other words, not every opportunity sitting in the Pipeline has the same value for revenue planning.
4. Pipeline Value and Its Potential to Become Revenue
One of the most common mistakes when looking at a Pipeline is taking the total value of all opportunities and treating it as achievable revenue.
For example, a business may have VND 10 billion worth of opportunities in its Pipeline. This sounds very positive, but VND 6 billion may still be at an early stage, VND 2 billion may be under consultation and only VND 2 billion may be at the final stage.
Clearly, the likelihood of converting that VND 10 billion into revenue within the period is not the same across all opportunities.
Therefore, CEOs need to distinguish between Pipeline value and the value of revenue that is realistically convertible.
When evaluating an opportunity, the business needs to consider the transaction value, current stage, historical conversion rates and expected closing time at the same time.
This approach enables more realistic revenue forecasting and reduces the risk of having a Pipeline that “looks good on paper” but fails to generate corresponding results.
In particular, if the business frequently sees a large gap between projected revenue and actual revenue, this is the time to review how the conversion potential of each stage is being determined.

5. Customer Sources That Generate Revenue
Not all potential customers have the same value.
One channel may generate thousands of registrations but have a very low conversion rate. Meanwhile, another source may generate only a few dozen opportunities but bring in high value contracts with shorter closing times.
If the business only looks at the number of potential customers, it can easily invest more in a source that appears to bring in “more customers” but actually generates little revenue.
CEOs should connect data from the top of the funnel with final results to understand:
- Which source generates the most opportunities?
- Which source has the best conversion rate?
- Which source generates higher contract values?
- Which source has a shorter conversion time?
When the entire journey is visible, the business can identify which customer sources actually create value, rather than simply knowing which sources generate the most customers.
This also provides a basis for allocating Marketing budgets, Sales resources and customer development activities more accurately.
Don’t Turn Measurement Into a “Counting Numbers” Exercise
Having enough data does not necessarily mean having enough information to make decisions.
After looking at the metrics, what the CEO needs is not another report, but answers to three questions:
- Where is the problem happening?
- Is the cause related to the process, opportunity quality or the way the team operates?
- Which area should be prioritized for improvement first?
For example, if the number of potential customers increases but the conversion rate declines, the business may need to review the quality of its incoming leads.
If the conversion rate remains relatively stable but closing times continue to increase, the problem may lie in the steps within the sales process.
If the Pipeline has a very large value but actual revenue is consistently much lower than forecast, the business needs to review how the conversion potential of each opportunity is being evaluated.
The issue may be the same: revenue. But each situation requires a different approach.
That is when data begins to create management value: not only showing what happened, but helping the business understand what to do next.
CRM Helps CEOs See the Funnel More Clearly
When a business manages opportunities through multiple Excel files, separate spreadsheets, emails or personal notes, consolidating the metrics above quickly becomes difficult.
A CRM system can centralize customer data, sales opportunities, Pipeline stages, assigned team members and processing history in one place. When data is updated consistently, the business can track the conversion process instead of simply consolidating results at the end of the month.
More importantly, CRM creates a shared data source where Sales and management can look at the same Pipeline.
Sales knows which opportunities they are responsible for. Managers know where opportunities are. CEOs can get an overall view of the revenue funnel without going through multiple layers of manual reporting.
However, CRM does not automatically make the revenue funnel healthier.
If the business has not clearly defined its sales stages, data is updated inconsistently or the team does not use the system correctly, the software simply becomes a place to store problems that already existed.
Therefore, technology should be viewed as a tool that helps businesses see and manage the revenue funnel more effectively, not as a replacement for management thinking.
How Often Should CEOs Give the Revenue Funnel a “Health Check”?
There is no single frequency that works for every business.
For businesses with short sales cycles and a large number of opportunities, metrics should be monitored more frequently to detect changes early. For businesses with longer sales cycles, monthly reviews or assessments by business stage may be more appropriate.
What matters is that the review becomes part of the management process rather than something that only happens when revenue starts to decline.
CEOs do not need to monitor dozens of metrics every day. A focused set of metrics that reflects the number of opportunities, conversion speed, processing time, Pipeline value and revenue generating sources can already reveal most of the important issues within the funnel.

A Healthy Revenue Funnel Is Not Simply a Funnel With Many Opportunities
A large Pipeline is not necessarily a good Pipeline.
A truly healthy revenue funnel is one where the business knows where opportunities are, how quickly they are converting, where the bottlenecks are and where resources are being allocated.
From a C-level perspective, the ultimate goal of measurement is not to have more impressive numbers in a report. It is the ability to identify problems early enough to make decisions before those problems turn into lost revenue.
Therefore, before asking, “How can we find more customers?”, perhaps the CEO should ask a different question:
“How well are the opportunities we already have being converted?”
This is also how WBL Group approaches Sales management: start by gaining a clear view of the current process and data, identify the bottlenecks, and only then select the right tools and solutions for improvement.
Because growth does not only come from putting more opportunities into the top of the funnel. Growth also comes from helping more opportunities make it to the end of the funnel.
