Hello,

May I know your inventory accounting method in system settings?

If it’s AVCO the avg_cost has been set wrongly for some reasons. You can reset that in sma_warehouses_products table.

If FIFO or LIFO, then please check the purchase code for previous orders.

Thank you

Kindly send me screenshot on how to resolve this issue, my accounting method is FIFO

Hello,

I am not sure why you have this issue. FIFO uses the cost from your purchases. You can check if any of the item has been purcahses for such cost.

Thank you
