Close Purchace invoice

When I issue a Purchase invoice, I want it to reflect on the expenses account directly, since we supply the materials to our project as an expense, not as a stock.
How can I make it?

You can create it as a service item and it will directly booked as an expense. All the stock items are currently booked to stock in hand during the purchase.

Thank you saumyaseelan
correct but is it possible to select the account for each purchase invoice, because now it hits only the default account which in a company setting.

for example: when I create Purchace invoice I want to select (electrical expenses ac, civil exp. ac etc.)

I found the solution,
just from Edit in table (Purchase Taxes and Charges) then select the account I need from accounting
