Tally is an accounts software mostly used for maintaining accounts in small scale business , personal and manufacturing sectors . In 1980′s we used books to maintain journal , cashbook and ledgers . Writing manual books for maintaining accounts is very difficult task to review reports .
In manual accounts a single transaction has to repeatedly write in so many accounts .
For examples : A company purchase goods on credit ,,
First of all to write journal entry in journal book as
Purchase a/c dr
to Party a/c Cr
Again the above entries to write in purchase ledger and party ledger . So a single transaction has write 3 times in manual books
Where as in tally no bother to enter so many times just enter this type of transaction in purchase voucher . Once you do that it will automatically post into purchase ledger and party ledger
