Citi provides consumers, corporations, governments and institutions with a broad range of financial products and services, including consumer banking and credit, corporate and investment banking, securities brokerage, transaction services and wealth management.

3. Overview of Citi’s Implementation of the Oracle E-Business Suite (EBS)
Citi’s Oracle EBS system enables employees, using a web browser, to request goods and services, obtain approvals electronically, and pay for the goods and services purchased.
This global initiative uses financial applications encompassing Accounts Payable, Fixed Assets, Expense General Ledger, and Procurement to leverage the power of a single integrated database with common data processes and standards.
Citi’s Oracle EBS system meets funding and prepaid accounts requirements, handles Citigroup legal entity and asset location codes, and maintains a structured approval process that meets Citigroup standards.
The Internet Procurement application is integrated with Oracle's Global Exchange (an electronic market place), which hosts supplier catalogs; and the Accounts Payable application supports electronic submission of supplier invoices, as well as electronic payments via existing Citigroup payments services.
Citi’s Oracle EBS system also includes an innovative web-based, decentralized invoice entry feature, e-Invoice, that can be used where appropriate.
Vision: Consolidate multiple legacy systems to one solution by implementing Citi’s Oracle EBS system in all Countries that Citi has businesses in and capture near 100% of expenses.
