The District Treasury Una went online with the inauguration of the new software OLTIS (Online Treasury Information System) on February 11, 2004. The Deputy Commissioner, Una Sh. Rajneesh, formally inaugurated the OLTIS Software. The software has been developed by the NIC HP State Centre for uniform implementation in the State of Himachal Pradesh. Latest software development tools and client/server model have been used in its development.

The OLTIS software is based on the work-flow of the Treasuries and data is captured right from the Token stage to its final passing. Besides linkages have been provided for AG office Voucher Level Computerisation, LIC data and departmental Budgetary controls. The special features include online verification of DDO signatures and photos of messengers, preparation of deduction registers, creation of data files for transmissions and DDO wise expenditure matching against budgeted amounts. The NIC HP was the pioneer in the country in Treasury computerisation when it developed the DISNIC-Treasury software in the 1990s. The earlier version of the software captured data in offline mode. The NIC District Centre, Una has implemented the software by imparting necessary training to the officials of the District Treasury and installing the software on the server/clients.
