SmartVista maintains a set of General Ledger (GL) accounts for every Institution entity in every working currency. These include the Profit and Loss, VAT and the various Transit and Suspense accounts that can be mapped against the relevant GL lines of the bank's main accounting system. As transactions occur, strings of postings are made up and down the account tree as specified in the Transaction Flow definition for each Transaction Type so as to keep full double-entry accounting for all the transactions processed and to provide the Core Banking System with all the accounting information required.
