## The use case: how B3 deploys Celonis

B3, the Brazilian Stock Exchange, uses Celonis Process Intelligence to detect duplicate invoices in Accounts Payable and to gain a single view of its Procurement process, which it restructured into three workstreams. It is now working with Celonis on an AI agent to automate contract renewals and is extending Celonis to Accounts Receivable and other areas.

Summary written by usedby from the source page, in English. The figures are those of Celonis and B3, not ours.

> Within just five weeks of go-live, the app delivered enough value to cover B3’s investment. It has since generated hundreds of thousands of dollars in value.

- **15 days**: “The restructure of B3’s Procurement process has already taken contract renewal from approximately 30 days to around 15 days.”

> Celonis is helping us understand our customers end-to-end. Instead of guesswork, we can use data to make decisions that will make our customers’ lives better.
