A voucher is a document that contains details of a financial transaction and is required for recording the same into the books of accounts. For every transaction, you can use the appropriate Tally voucher to enter the details into the ledgers and update the financial position of the company.
There are basically two types of voucher entries:
The voucher entry menus options are available under Transactions in the Gateway of Tally. The Payroll and Order Vouchers are available as separate options which can be enabled based on the requirements.
The Payroll Vouchers can be enabled from F1: Accounting Features, whereas the Order Vouchers can be activated from F2: Inventory Features.
Note: If the company is maintained with Accounts Only Company, Inventory Vouchers option will not be displayed under Transactions.
