What Is Revenue Leakage? A CEO's Guide to the Money You Already Earned

Most of the money a growing company loses never shows up as a loss.

It shows up as a discount someone gave to close a deal in the last week of the quarter. As a rush job that was delivered but never invoiced. As a customer who pays in 75 days on 45-day terms, every month, for three years. Each one is small. Nobody decided to lose it. And because nobody decided, nobody owns it.

That is revenue leakage. In the companies I have worked with across Vietnam, Malaysia and Singapore, it is usually the most expensive problem in the business. Almost none of them had a line for it in the management report.

Revenue leakage is money your company earned, or should have earned, and never collected or kept.

The work was done. The product shipped. The customer got the value. But somewhere between the contract and the bank account, part of the money went missing.

It is different from a bad year. A bad year is when demand drops or a competitor wins. Leakage happens in good years too, and it often gets worse when the company is growing fast, because growth hides it. Revenue is up 25%, so nobody asks why margin only moved by two points.

It also gets worse with distance. A group run from Singapore, with a plant in Bac Ninh and a sales team in Kuala Lumpur, has more handoffs, more currencies and more layers of reporting than a business under one roof. Every one of those is a place for money to slip through.

> You are not alone if you have never measured it. In a Boston Consulting Group survey of more than 2,000 business leaders, 45% said revenue leakage was a systemic problem in their company. Systemic, not occasional.

In practice, leaks cluster in a handful of places. If you only read one part of this article, read this list and ask which ones exist in your business.

Discounts nobody approved. A salesperson gives 8% to close. The approval rule says 5%. Nobody checks, because the deal is already signed.

Work delivered but not billed. Scope creep, extra site visits, "quick" change requests, rush fees that were waived. I wrote about this in more detail in Scope Creep Is Free Work.

Contract terms that work against you. Penalty clauses, service credits, free warranty extensions, price-lock periods that outlived inflation.

Slow cash. Invoices sent late, sent wrong, or not chased. Your profit is real, but it sits in a customer's bank account instead of yours.

Rework and quality failures. Doing the same job twice, in a factory or a software team. The American Society for Quality puts the cost of poor quality at 15-20% of revenue in many manufacturers.

Unprofitable customers and products. The account that looks big on the revenue report and small, or negative, once you count the cost to serve it.

Supplier price creep. Your vendors raise prices 3% a year. Your contracts with customers do not move.

Some of these are internal: money lost inside the business through waste and poor control. Others are external: money handed to customers or suppliers through weak terms. The difference matters because the fix is different. I have written about that split in Internal Bleed vs External Bleed.

Let us put numbers on it. Take a Singapore-headquartered group doing $40 million a year, with a factory in northern Vietnam and a sales office in Kuala Lumpur. It runs at a 6% net margin, so $2.4 million in profit.

Now assume four modest leaks, the kind I would expect to find in a company that size:

Leak	Assumption	Annual cost
Unapproved discounts	1.5% of revenue above policy	$600,000
Unbilled extras (rush, freight, changes)	0.5% of revenue	$200,000
Slow collections	DSO 75 days on 45-day terms, cash costs 9% a year	~$296,000
Rework and returns	1% of revenue	$400,000
Total		~$1.5 million

That is 3.7% of revenue. It sounds manageable until you compare it to profit. It is more than 60% of what the business made all year.

None of those assumptions are extreme. Every CFO reading this will recognise at least two of them.

> Key Stat: In a $40M business with a 6% net margin, four modest leaks totalling 3.7% of revenue wipe out more than 60% of annual profit.

This is the part CEOs find uncomfortable. The people closest to the leaks usually know about them. They just do not see them as leaks anymore.

Three things happen as a company grows.

The leak becomes normal. The sales team has always discounted at quarter end. The plant has always reworked 4% of output. After two years, it is just how things work.

Nobody owns the gap between departments. Sales owns the deal. Operations owns delivery. Finance owns the invoice. The money gets lost in the handoffs, and every department can show that its own part was done correctly.

Bad news gets softened on the way up. Each layer of management rounds the problem down a little. By the time it reaches the CEO, a $600,000 discount problem has become "some pricing pressure in Q3." I covered this pattern in Why CEOs Lose Visibility as the Company Grows.

Distance makes it worse. When the CEO sits in Singapore and the plant is in Hai Phong, the monthly report is the only window into the operation. If the General Director writes "on track", that is what head office believes. Culture adds another layer: in many teams across the region, nobody wants to be the one who brings the boss bad news.

So the CEO finds out last. Often from an investor, a buyer's due diligence team, or a cash crunch.

You do not need a six-month project to get a first view. You need three things.

Compare what you should have earned with what you actually collected. Pick 20 recent deals. For each one, compare the list price, the contract price, the invoiced amount and the cash received. The gaps between those four numbers are where leakage lives.

Ask each department head one question. "What do we give away that we do not charge for?" You will get defensive answers at first. Ask again a week later.

Price every leak in dollars, not percentages. "Rework is 3%" gets discussed. "Rework cost us $410,000 last year" gets fixed. A number with a dollar sign forces a decision.

Once a leak has a price, it needs one owner, one metric and one date to close. Without that, the list becomes a report that everyone agrees with and nobody acts on.

Every business leaks. Some leakage is the cost of moving fast, and chasing every last dollar would slow you down more than it saves.

The goal is simpler: the CEO should know where the money goes, roughly how much, and which three leaks are worth fixing first. That is the difference between a company that loses 8% of its revenue without noticing and one that decides what it is willing to lose.

If you run a business across Singapore, Malaysia or Vietnam and want a structured way to do this, our Executive Leak Assessment takes one to two weeks and gives you a priced list of your five to ten largest leaks.

What is revenue leakage in simple terms?

It is money your company earned, or should have earned, but never collected or kept. Common causes are unapproved discounts, unbilled work, slow collections, rework and weak contract terms.

How much revenue do companies typically lose to leakage?

It varies by industry and maturity. In our experience, growing companies commonly lose several percent of revenue, which can equal a large share of their annual profit. The only reliable number is the one you measure in your own business.

What is the difference between revenue leakage and revenue loss?

Revenue loss usually means sales you did not make, because of lower demand or lost customers. Leakage is money from sales you did make that never reached your bank account or your margin.

Who should own revenue leakage in a company?

The CEO should own the overall view, because leakage usually sits between departments. Each individual leak then needs one named owner with a metric and a deadline.

Is revenue leakage worse in companies that operate across several countries?

Usually, yes. Every border adds handoffs, currencies, reporting layers and distance between the CEO and the operation. Groups with a head office in Singapore and operations in Vietnam or Malaysia often find their biggest leaks in the gaps between entities.
