Billing Authorities send information to the Valuation Office Agency. This information, required to assist in maintaining valuation and rating lists, is called a billing authority report or BAR. Some Billing Authorities submit their BARs electronically using the e-BAR facility. As the e-BAR is electronic, and can be in different formats, it is not possible to provide a typical e-BAR.
The various data exchanges between billing authorities, the Valuation Office Agency, and the National Land and Property Gazetteer covered by the former Valuebill project can be regarded as the Valuebill interface. The e-BAR facility is a development, based on a Valuebill schema, to enable Billing Authorities to send electronic reports to VOA.
