Beginning April 18, 2011, the City will centralize invoice entry and payment processing at the Office of the City Comptroller for most contracts. This means that, if your contract is eligible for centralized invoice processing, you should submit your invoice DIRECTLY to the Comptroller’s office for expedited processing.
This reference list of eligible contracts will be updated each month to ensure that newly-awarded contracts are included in the current list. Contracts will continue to appear on the list for six months past their expiration; after that time, they will be removed from the list.
In addition to standard invoice information (vendor name and/or number, remittance address, invoice number and date, amount due, and details on goods or services delivered to the City of Chicago), you should include the following information on your invoice to ensure the fastest-possible payment…
Please note that if your invoice is missing any of this information, payment WILL be delayed.
The Comptroller has directed each City department to enter Receipts in our accounting system with accurate and timely details on the quantity of goods or services you have delivered. Once the Receipt is entered, the department should provide you with the Receipt number. Please note that we have left it to each department’s discretion as to what communication channel (phone, email, letter, etc.) they will use to send Receipt numbers.
If your contract isn’t eligible for centralized invoice processing, you should send your invoices to the ordering department for entry and preliminary processing.
If you are providing goods or services to the City of Chicago WITHOUT a contract, you should send your invoices to the ordering department for entry and preliminary processing.
