How is inventory recorded ? Is part pf P/l Statement

Is inventory recorded as part of Profit and Loss statement ?

Like say the company is doing normal business but decided to enhance performance and stacked up a X million of inventory . So does that make the net profit negative for the quarter / year ? How is it accounted ?

yes. increase / decrease in work in progress as compared to earlier year will be taken as profit or loss in the P&L account.
