Closing Stock

Hello Experts,

As per 2017-18 balance sheet our closing stock is 10086081 including stock at
godown & work in progress of the projects.
In the year 2018-19 we have cleared all our stocks at godown & our projects have been shortclosed where there is no work in progress. In this case my sales is 1.21 cr, purchase is 8.33 L, op/s will be cl/s of last year so there will be more expenses,
In this case we can get only loss, how can we increase our profit margin here?

Help me out in this pls
