Ind. Code § 5-11-12-1
Anything in existing law pertaining to the mode and form of records and accounting system in the offices of the county treasurer and county auditor to the contrary notwithstanding, hereafter the several boards of county commissioners may provide for the installation of modern tax accounting systems in the offices of the treasurer and auditor of such counties by certifying a detailed description of the proposed installation and system and the records, books, ledgers and forms proposed to exemplify such systems and methods to the state board of accounts of the state of Indiana after approval by such board of county commissioners. The said state board of accounts shall examine the forms, systems, and methods so proposed and if approved, shall certify that fact to such board of county commissioners and thereupon such board of county commissioners shall be at liberty, if it find that the installation and adoption of such new system and the use of such new forms will be of benefit to the county and that such benefit will exceed or at least equal the cost thereof, to install, adopt and order the use of such new system, forms, ledgers, and methods; but no expenditure for forms or equipment shall be made nor any obligation incurred for that purpose until funds therefor have been appropriated by the county council as now provided by law. No such records, books, ledgers, forms, system or equipment shall be installed or purchased or leased until and unless the board of commissioners shall have invited and received bids thereon in the manner and subject to the provisions of law concerning the purchase of other county materials, supplies and equipment.
