I am trying to set up a service company with multiple branches [3] in OpenERP 7.0. The nature of business is same at all the branches, though a branch has only some departments. I was advised to use multi company module, but I am not convinced about using multiple companies and different chart of accounts of each company. I am looking at having 1 chart of accounts, that is available at all branches, though some minor heads may be zero for them.

The BS and P&L of the company should reflect the summation of all the branches. Please advise.

Thanks
