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
