Branch accouting in tally

Hello Everybody

I need to maintain branch accounts for my company. The HQ has 3 branches, each handling sales on their own. The expenses are borne by HQ.

How should I do the following, in tally?

1. Book sales, expenses etc , brach wise?

2. Be able to pull out branch wise P&L, Balance sheet?

3. Show consolidated revenues/ expenses in the HQ Books?

I use Tally ERP.

Appreciate a quick response.

Thank you
