Submission and Receipt of Bills
Section 900
Section 900.80 Submission
and Receipt of Bills
a) A bill submitted, lacking sufficient and/or correct information
required by the State agency to process the bill, lacking taxpayer
identification number, or to an address or person other than one designated in
written instructions from the State shall not be considered a Proper Bill until
it is completed, additional information provided, or it reaches the proper address
or person.
b) A bill submitted lacking the Vendor's federal taxpayer
identification number shall not be considered a Proper Bill until the Vendor
provides the taxpayer identification number or a completed Internal Revenue
Service Form W-9 or Form 147C certifying that the Vendor's taxpayer
identification number has been applied for but not received and that the Vendor
is not subject to backup withholding due to underreporting.
c) A bill received prior to acceptance of Goods or Services by
the State shall be considered a Proper Bill no earlier than the date of
acceptance. Acceptance means the date on which the State, to the best of its
ability at that time, determines contract requirements have been met.
Acceptance for late payment calculation shall not be used by any Vendor to show
acceptance of the Goods or Services for any other purpose.
d) A bill received after acceptance of Goods or Services may be
considered a Proper Bill no earlier than the date of receipt of the bill.
e) A Vendor may submit bills for future performance, such as to
make lease or installment purchase payments, in advance of scheduled due dates,
but such bills for purposes of this Part shall not be considered received by
the State any earlier than when the future performance by the vendor begins.
f) When the parties do not contemplate submission of a physical
bill to the State, such
as to make scheduled payments per the terms of a
contract, the date of final receipt or
acceptance, whichever is later, of
the Goods or Services shall be considered the date of the bill.
g) State employees who are reimbursed by the State for their
travel may receive late payment interest in accordance with this Part.
