IL SB2845

State agencies must confirm receipt of contractor bills or invoices within 15 business days and transmit approved amounts to the Comptroller within 30 days of receipt.

Voucher information (number, date, and amount) must be made available electronically within 15 business days of submission to the Comptroller, replacing the previous "promptly" requirement.

Agencies may pay interest liabilities from any appropriated funds not prohibited for that purpose when federal rules prevent charging interest to the original expenditure account.

Agencies must review bills within 30 days and notify vendors of any defects; approved portions of partially-disapproved construction invoices must still be paid.

Eliminates obsolete payment provisions from before fiscal year 2012, consolidating the 90-day payment deadline with 1.0% monthly interest penalty for late payments.
