GST / VAT Accounting (GVA) is an easy-to-use program that is designed to maintain complete and accurate accounting of income and expenses with particular emphasis on tracking GST or VAT taxes collected and paid.. GVA uses the "single entry" bookkeeping method. This accounting method is easy to use and is equally suited for small businesses and individuals. Using GVA, you can produce a variety of expense, income, profit, general ledger and tax reports. You can define up to 1000 different income and expense accounts to fully categorize your income and expenses for tax purposes. Having your records fully organized can save you time and money at tax time. GVA employs the concept of folders where each folder contains income and expense data that may be reported either separately or in combination. Thus, GVA may be used for multiple businesses, multiple divisions within a single business or for both business and personal accounting.
