Invoice Scanning and Imaging System (ISIS) Home

There are two approved systems for procuring goods and services in Defence:

  1. Resource Output Management and Accounting Network (ROMAN): in which purchasing occurs through a ROMAN Purchase Order or the Defence Purchasing Card (DPC); and
  2. Standard Defence Supply System (SDSS): in which all purchasing must be supported by an SDSS Purchase Order

These systems are supported by separate payment processes, including invoicing addresses.

Your company may receive orders from areas within Defence that use one or both systems to purchase goods and services. This is why you must send your invoice to the correct invoicing address, which can be found on your Defence Purchase Order, and not set up default invoicing addresses for all Defence purchases.

The information contained in this website is intended for suppliers whose goods or services are being purchased by Defence staff using ROMAN and Defence's recently introduced centralised accounts processing centres.

If the invoicing address on your Defence purchase order is the address listed below, then this site is for you.
