Sale of Machinery Entry

Our firm has sold some machinery worth 5 lacs. How these entries will be recorded in Tally.

With journal voucher we can pass the entry :-

Buyer A/c     Dr.

  To Machinery A/c

Then from receipt voucher we can make the following entry :-

Bank A/c      Dr.

   To  Buyer A/c

But how to pass sale of machinery entry through sales voucher, so that sales can be affected in tally and vat could be charged. Pls guide.

Thanks in Advance
