Different Unit Cost Values in Item Card and in the Sales Invoice

(0) ShareShare

Posted on by Oguzhan Gok 19

Hello,

I'm trying to understand why the Unit Cost is different in the Average Cost Calc. Overview in the Item Card and the posted invoice of the same item. Lets take an example;

For this item, in the date of 27/02/2022 Unit Cost calculated as 77.55 and this is the first entry in the system. When I look at to the posted sales invoice of the sale mentioned here (6 quantities), as you can see unit cost seems as 78,45. 

Till next valuation time (17.06.2022), there is no other record of purchase or sale. I dont understand why they are different, and we have other cases like that.

Thank you for your help,

Best Regards

I have the same question (0)

    first you need to make sure the cost has been adjusted and posted for this item so it is accurate.

    second the value in posted unit cost should be correct if the costs have been trued up/set up is correct etc.

    Average cost has its own way of calculate unit cost based on many factors.

    The unit cost value on item card is calculated using a different logic. It is more like an estimation in a sense especially for average cost items.

    you could read the below document to get a better understanding:

    Press on Unit Cost (it should be as flowfield) and You will see how it calculates and what events affect it.

    Maybe add a screenshot of that with latest rows expanded, if You still have questions.

    Also is the Cost is Adjusted = true on the item ?If not it could be the reason, and You should run the Adjust Cost - Item entries process.
