How are cost prices used in Sumtracker

Cost prices are used in reports for cost of goods sold and stock valuation. When you export product list or stock by location, the cost per unit and total cost value is exported for each product.

Cost Prices can be updated through the following ways:

  • manually updated in products

  • automatic update through Purchase Orders

The cost prices of products in Sumtracker do not include any taxes. They represent the basic amount of purchase for each product.

Update cost price of products individually

  • Click on Product SKU in Product List

  • Add cost and save the product

Update cost price of products in bulk

  • Export the Product List

  • Add Cost corresponding the Product

  • Import the List

How are cost prices updated through Purchase Orders

Cost per item for each product can be updated right from the Purchase Orders.

We use the weighted average pricing model based on your existing inventory only.

When you receive items in a Purchase order, the cost of the product is updated as per the following calculation.

We calculate the per unit landed cost of the product in the PO.


The currency conversion rate is 1 if the PO is made in default currency. If you are using any other currency, then you must update the correct conversion rate in PO.

After calculating the landed cost, we calculate the new cost price as follows

We do not update the cost of product if you have filled 0 in the purchase price of the product in PO

Sample cost calculations

Here's how the calculation for cost is done with simple examples:

Case 1

existing inventory = 10 units

existing cost = 10 USD/unit.

Now you received 10 units @ 6 USD/unit.

So the calculation which will happen is

New cost = (10 x 10 + 10 x 6)/(10 + 10) = 8 USD/unit

Case 2

Lets say you sell some pieces and now you have 5 units left.

You receive 10 units at 5 USD/unit.

New cost = (5 x 8 + 10 x 5)/(5 + 10) = 6 USD/unit

Case 3

Lets say you sell all pieces.

Now you buy 10 units at 4 USD/unit.

New cost = (0 x 6 + 10 x 4)/(0 + 10) = 4 USD/unit

Case 4

Let’s say that you haven’t updated the cost for a product yet.

existing inventory = 10 units

existing cost = 0 USD/unit.

Now you received 100 units @ 6 USD/unit

The new cost will be 6 USD/unit
