When a B2B portal stops billing correctly: Invoicing failure

Invoices with a text "Unnecessary costs"

B2B marketplaces are the backbone of supply chains. Every day, businesses use them to order essential goods for their operations. Accurate billing is critical—for both suppliers and customers. But this time, something went wrong.

Some received invoices for goods they never ordered

Orders were coming in, the system was registering them, and deliveries were going out as usual. The problem surfaced only when customers began reporting issues with their invoices. Some received invoices for goods they never ordered, others were missing parts of their orders, and some didn’t receive an invoice at all. The initial response from customer support? An isolated glitch. But soon, dozens more reports started coming in.

An investigation revealed the issue occurred during the invoice generation process. The billing system pulled its data from the ERP system—but the data synchronization had failed. Due to an error in the connection between the data warehouse (DWH) and the ERP, some customer orders were incorrectly matched to invoices. The ETL process that was supposed to run each night, processing the full batch of orders and preparing them for billing, had failed. Some transactions were duplicated in the system; others didn’t make it into the invoicing process at all.

How did no one notice the ETL failure sooner?

The result? Accounting chaos, dissatisfied customers, and dozens of invoices that had to be fixed manually. Some businesses withheld payments because the invoices didn’t match the delivered goods. Internal teams had to put out the fire manually, causing further delays and avoidable costs.

The fix took time and required a lot of manual intervention. But the real question is: how did no one notice the ETL failure sooner? Why were there no control mechanisms in place to detect discrepancies between orders and invoices?

We’ve left out the names—but if this story sounds familiar, you probably have the same problem. IT outages aren’t a matter of if, but when. The difference lies in whether you can predict them—and fix them fast.
