Accounting import purchase

Hi Friends,

I am wanting to know how to account import purchase i.e step by step accounting entries from the moment of placing import purchase order till the final lot clears from customs and the final settlement of all the ledgers created in connection with import purchase. Also i want to link this with bill of entry no. so that i can trace the payable or receivable at the final stage. pls note that the accounting is done in Tally 9 ERP.
