Yes, the bank account is must if you are going to start a business.
If you are starting to buy products from the local market or we can say India Mart then Saving account is necessary.
If you are importing product from Alibaba.com then you require a current account not saving the account.
Or is bank going to charge a lot for that………..
No bank does not charge a lot.
