The new version of General Accounting 3S/Financial Management consists of a family of applications that thoroughly covers the needs of a modern Greek tourism business accounting. A characteristic of the new application is its extension beyond the accounting coverage of a company in matters such as analytical accounting, the automated issuance of cash receipts, the monitoring of foreign currencies, open items & VAT packages. The application was implemented with client-server technology for a Windows environment, with the logic of a basic system, General Accounting, to which additional subsystems are added depending on the client’s needs.
