Tally show the only tally function which are mention in tally but accounting treatment by the Journal Entries i.e. If you purchase/sale any goods Rs. 1000 and recd. the cash discount Rs. 100. We have passed the said entry
This is my guess that is Journal, sale & purchase but actual when you open the tally software. It shows at right side uses of keys. Tally software is simple use for accounting.
