What Is Revenue Leakage?
Revenue leakage is money a company has earned under its prices, contracts and policies but never invoices or collects. It shows up as discounts above policy, price increases that were never applied, prices billed below contract and late payment interest that nobody charged. Each gap is small on one invoice line and large across a year of sales.

What Is Revenue Leakage in Simple Terms?
Revenue leakage is the difference between what you should have billed and what you actually billed or collected. The customer did not leave and the sale did happen, but part of the agreed value never reached the books. That is why it rarely shows up in a P&L review.
Most leakage is not fraud. It comes from ordinary gaps between systems and teams: a new price list that never reached the ERP, a contract price kept in a PDF, a discount approved by email, or one customer living under three codes with three different terms. Each of these looks normal on its own, so the loss hides in the detail of invoice lines rather than in monthly totals.
Revenue Leakage Examples on the Invoice Line
In B2B sales, distribution and manufacturing the money slips away in a few familiar places. Prices stay below what was agreed, discounts grow beyond what anyone intended, returns are credited more generously than the original sale, customer records split one relationship into several, and payment terms are not enforced when customers pay late. None of it raises an error in the ERP, and all of it lands directly on margin and cash.
What Causes Revenue Leakage?
- Price changes that arrive late. A price increase is announced, but prices in the ERP are updated weeks later or only for some customers.
- Contracts outside the system. Contract prices and rebates live in documents and spreadsheets, so invoicing falls back to the list price or an old special price.
- Discount approvals by email. Exceptions granted for one deal stay in place for every later order.
- Messy master data. Duplicate customer cards, invalid tax IDs and missing payment terms make it impossible to apply the right rule to the right customer. See master data quality.
- Nobody owns the rule. When no one owns the discount policy or the late interest term, nobody notices when it is not applied.

Revenue Leakage vs Churn
Churn is revenue lost because customers leave or buy less. Revenue leakage is revenue lost while the customer stays and keeps buying. They need different fixes: churn is a sales and retention question, leakage is a pricing, billing and data question.
| Revenue Leakage | Churn | |
|---|---|---|
| Customer | Stays and keeps buying | Leaves or reduces volume |
| Where It Shows | Invoice lines, credit notes, receivables | Order volume, renewals |
| Typical Cause | Prices, discounts, terms and data not applied | Product, service or competition |
| Who Fixes It | Finance, pricing, sales operations, data owners | Sales and customer success |
How to Detect Revenue Leakage
Revenue leakage is hard to see because ERP data looks correct. Every line was approved, every total reconciles, and the rule that should have applied usually sits somewhere else: in a contract file, an email or a price list that changed mid-year. Telling a real leak from a legitimate exception takes knowledge of how your ERP stores prices and customers and how your business actually sells.
That is the work korppi does for finance teams. If you want to know what is leaking in your own sales data, the fastest route is a short conversation with us, followed by a report on your own invoice lines.

How to Prevent Revenue Leakage
Prevention comes down to owners, rules and a repeat measurement:
- Give every important field an owner and a rule, for example the payment term owned by credit control. This is the core of data governance.
- Keep contract prices in the ERP, not only in documents.
- Write the discount policy down and route exceptions to an approver.
- Measure again regularly, so you can see whether each leak is shrinking or coming back.

A 1% better price lifts operating profit by about 8.7%.
Pricing is usually the largest source, so it has its own guide: pricing and discount leakage.
What korppi Delivers
korppi is revenue intelligence software that first puts sales data in order, then shows where revenue leaks down to the invoice line and gives every leak an owner. It works from a read-only standard export of systems such as SAP, Logo, Netsis and Mikro, and it never writes back to your system. See supported ERPs.
Every figure is calculated from your own lines and linked to the invoice lines behind it, so finance can verify each amount before acting on it. korppilot, the AI assistant, explains the results in plain language, but it never invents numbers. The first step is the korppi Data Health Report, and the ongoing work runs in korppi Revenue Intelligence.
Start With a Data Health Report
The best way to see revenue leakage is on your own data. Request a Data Health Report and you get line-level evidence of where money slips away, with an amount and an owner for each finding. If you prefer to see korppi first, request a demo and we will walk you through it.
Frequently Asked Questions
Is revenue leakage the same as fraud?
Usually not. Most revenue leakage comes from process and data gaps, such as price lists updated late, contract prices kept outside the ERP or duplicate customer records.
How much revenue do companies lose to leakage?
It depends on the business and its data, so any single percentage should be treated with care. One sourced reference point: World Commerce & Contracting estimates that close to 9% of contract value is lost to poor contract management. The only reliable figure for your company is one calculated from your own invoice lines.
Who should own revenue leakage in a company?
Finance leadership usually sponsors it, but each leak needs a specific owner. Pricing owns price lists, sales operations owns discount approvals, credit control owns payment terms and late interest, and a data owner looks after the customer master.
What data do I need to detect revenue leakage?
A read-only standard export of your invoice lines, price lists and customer records is enough. We agree the exact export with your team on a call.
Can my ERP prevent revenue leakage on its own?
An ERP applies the prices and terms it is given, so it can only be as correct as its master data and price conditions. If a contract price, a price increase or a late interest term never reaches the system, the ERP will bill the old value without any error. An independent review of what was actually billed closes that gap.
