It shall be the duty of every vendor to keep and preserve suitable records of all
sales made by such vendor and such other books or accounts as may be necessary to
determine the amount of the tax for the collection or payment of which such vendor
is liable under this article. It shall be the duty of every such vendor to keep and
preserve for a period of four (4) years following the due date of the return or the
payment of the tax all such books, invoices and other records necessary to determine
the tax, and the same shall be open for examination by the manager of finance. Upon
demand by the manager such vendor shall make the books, invoices, accounts or other
records it maintains available at the office of the manager or some other place designated
by the manager for examination, inspection and audit by the manager. The manager,
in the manager's discretion, may make, permit or cause to be made the examination,
inspection or audit of books, invoices, accounts and other records so kept or maintained
by such vendor. When such vendor shall have entered into a binding agreement with
the city to reimburse it for all costs and expenses incurred by the city in order
to have such examination, inspection or audit at a place other than the place designated
by the manager, then such examination, inspection or audit shall be made where such
records are kept or maintained by the vendor or as otherwise designated in the agreement.
