What does revenue leakage cost?

Revenue leakage costs you more than the amount you fail to invoice. Because the cost of the work or delivery has already been incurred, every euro of missed revenue comes straight off your profit. With recurring contracts, the leak repeats every year and grows through missed indexation. The commonly cited estimate is 1 to 5 percent of revenue, but because of that margin effect, the impact on your profit is a multiple of that percentage.

The direct cost: revenue you do not invoice

The first and most visible part of the cost is the revenue itself. A project whose additional work was not invoiced, a subscription at too low a price, a contract whose indexation was forgotten. That is money you should have received under the agreement and that never came in.

The commonly cited range for this part is 1 to 5 percent of revenue, with smaller companies more likely towards the top. What that means for a typical B2B company, and why it is an estimate rather than a measurement, is covered in how much revenue leaks on average. How to calculate it for your own company is in how to calculate revenue leakage.

But the direct amount is only the start.

Cost 1: the margin effect

This is the part most people underestimate. Leaked revenue is not ordinary revenue. It is revenue for which you have already incurred the costs.

An engineer carried out the additional work. The wages have been paid, the materials bought. The software is running for a customer who uses more seats than they pay for. The servers cost money, support answers their questions. If you do not invoice that revenue, you do not only lose the revenue: you have already incurred the costs.

That is why every euro of leakage counts almost entirely as lost profit. For a company with a 10 percent net margin, EUR 100,000 of leakage is not 1 percent of profit, but the equivalent of the profit on EUR 1M of new revenue.

Worked example: a service provider with EUR 8M revenue

Suppose your company has EUR 8M in revenue and a net margin of 8 percent, so EUR 640,000 profit. You leak 2 percent: EUR 160,000. This is an example.

• The leakage is 2 percent of your revenue.
• Because the costs have already been incurred, it is also EUR 160,000 less profit.
• That is 25 percent of your net profit.
• To earn the same EUR 160,000 of profit through new revenue at an 8 percent margin, you would need EUR 2M of additional revenue.

That last point is the crux. Closing EUR 160,000 of leakage delivers the same as winning EUR 2M of new revenue, without acquisition costs, without extra staff and without extra delivery.

Cost 2: compounding over years

With one-off sales, a leak is an incident. With recurring contracts, it is a pattern. A subscription set too low stays too low until someone corrects it. A contract that was not indexed stays at the old price, and the next indexation is calculated on the amount that is already too low.

That makes missed indexation particularly expensive. Suppose a contract worth EUR 50,000 a year with 3 percent annual indexation is not indexed for three years:

The leak grows every year. And if you discover it in year four, it is commercially difficult to raise the customer's price by 9 percent in one go. Often the difference is never fully recovered. More on this in revenue leakage from missed price indexation.

Cost 3: working capital

Part of the leakage is not lost revenue but delayed revenue. An invoice sent three months late is eventually paid. An overdue invoice that is not chased may still come in after six months.

That seems harmless, but it costs money. During those months, you are financing your customer's work. If you use a credit facility, you pay interest on it. If you have no credit, it limits what you can invest. For fast-growing companies, a structural delay in invoicing can make the difference between growth funded from your own resources and growth that needs external finance.

Cost 4: valuation

If your company is ever sold, financed or valued, people look at revenue and profit, often at a multiple. Every euro of structural leakage lowers that valuation by the same multiple.

There is a second effect. In due diligence, a buyer looks at the quality of your revenue. A large gap between your CRM and your accounts, contracts that were not indexed, or customers who structurally pay too little are signs that your processes are not in order. That leads to a lower price or heavier warranties, regardless of the amount of the leakage itself.

Cost 5: poor decisions

When your figures are wrong, you make decisions based on a wrong picture. A few examples:

• A product line looks profitable, but part of its revenue is never invoiced. You invest in it while the real margin is lower.
• Your forecast is higher than what comes in, because some won deals are not invoiced. You hire people on the strength of revenue that will not arrive.
• A customer looks profitable, but has had a discount for three years that should have ended after one. You give them an even bigger discount at renewal.

These costs cannot be expressed in euros, but they are often greater than the leakage itself.

Cost 6: time

Finally, revenue leakage costs time, even when you are not actively looking for it. Finance spends hours working out why figures do not reconcile. Sales and finance argue in meetings about which number is right. Customers call about incorrect invoices and need calling back. Credit notes have to be raised and explained.

That time is measurable. Ask the people who do it how many hours a month they spend investigating and correcting revenue differences.

Putting it all together

For a business case, use the first three and possibly working capital and time. Mention the rest as a benefit without an amount. How to weigh that against the cost of a solution is covered in what Revenue Intelligence delivers.

How to establish the cost for your own company

1. Pick three to five types of leakage that fit your business. There is a list in examples of revenue leakage.
2. Check a sample. For example twenty contracts, twenty projects or one quarter of deals.
3. Convert the amounts found to an annual figure.
4. Separate one-off from recurring. A forgotten invoice is one-off, a wrong price is recurring.
5. Divide by your net margin to see how much new revenue you would need for the same profit.
6. Project the recurring leaks over three years, including indexation where it applies.

That gives you a well founded figure, based on your own data rather than a general percentage.

Frequently asked questions

Is revenue leakage the same as a loss?

Not exactly. A loss is an accounting concept: your costs exceed your income. Revenue leakage is revenue you were entitled to and did not receive. It does not appear as a loss in your books, but as lower revenue and lower profit. That is why it is so hard to see.

Why is the impact on profit so much greater than on revenue?

Because the costs have already been incurred. New revenue brings new costs with it. With leaked revenue, you have incurred the costs and missed the income. So every euro of leakage is almost a full euro of profit.

How much of the leakage can you recover?

That varies by type. A forgotten invoice from last month can usually still be sent. A discount that has run two years too long is rarely recovered retrospectively. In your business case, count the ongoing part and treat the past as a bonus.

What does doing nothing cost?

The amount of the leakage, every year again, plus the growth of the recurring leaks. Because new contracts and changes keep producing new discrepancies, leakage usually grows along with your company.
