Hi We are into th business of Web Hosting & Domain Mangement. We wanted to understand how do we keep teh stock of servers for eg. I buy a server on 11months or 3months rent which is 1TB space and then break this space into various MB and sell. So how do i maintain my stock system in teh sense is how to create the group and stock items if someone can help. Awaiting a positive response. EG: I buy a server say Linux Dedicated 1TB for 13500.00 INR P.M where i set quaterly payment When i sell to my client I raise the invoice in the following format. 100MB Linux server for 2000.00 INR P.A (Here 100MB is a stock) So 100MB has to be deducted from 1TB + i am billing the client for 1 year whereas i am being billed for qarter.... so how do i do this kind of entry in tally.
