I have developed another presentation on Upto what extent you can do excise accounting without any customization with the help of latest rel 1.2 of Tally.
Some of Tally's old partners are working hard on excise module of tally with excise registers but no one has come up with a complete solution.
In the mean time tally users can get maximum out of tally with the help of this slideshow.
Any suggestions are welcome to improve the contents.
