Job Work

 scenario

We are a prop. firm, non excise. We buy a 'product A' and get some job work done on it and sell it to end user. 

The job worker raises an invoice on us charging 'VAT on material charges' and 'Service Tax on labour charges'.

Guide me how to make voucher entry. I am using Tally 7

So Far: make a sub head JOB WORK under purchases head and make a non item invoice entry as - Purchase A/c Dr. (Balance Amount), Input VAT A/c Dr. (VAT Amount), Party A/c Cr. (Invoice Amount)
