What is WAP and what is the purchase price?

The purchase price of a product is the price you pay to your vendor - your vendor’s sales price.

The cost that will be posted to your cost of goods sold, when you sell an item, is called “WAP” (Weighted Average Price) and is calculated from the cost you purchase ([(# pieces X # amount) + (# pieces X # amount)] / total pieces). The receiving note is the leading document to update and value your inventory.


The WAP calculates an average of all products purchased. An example:

You buy: 10 products for $10 each = $100 into your inventory

You buy: 20 products for $15 each = $300 into your inventory

Your total value is now: 30 products for a total cost of $400 and this is a WAP of $13.33 per product


The WAP is then used to generate your costs of a sold product as soon as you deliver that product. The delivery note generates the inventory movement and the posting of your cost of goods sold into the profit & loss accounts specified in your product

Can I valuate my inventory using FIFO or LIFO?

Can I link my product to a vendor?

Should you not use your product family option otherwise, you could use it to group your products according to the vendors you buy from.

Should the product group be used otherwise, you might eventually set a prefix to your product code to identify the product accordingly, when you select it in a purchase order for your vendor.

Vendor price lists would you to set up purchase prices by vendor for the according products. When you then create a purchase order for this vendor and add the products, the correct price will be drawn.

Why can’t I delete a product?

OneUp allows to delete products only, if there is no transaction linked. A transaction could be:

  • There is a quantity available in stock on hand
  • The product is used in any kind of sales or purchase document
  • The product was used in an inventory count sheet, an inventory transfer or any other inventory related transaction

To be able to delete the product, you would need to delete the linked documents and transactions and have no more quantity available in your stock on hand.

Should it not be possible to delete the linked transactions, it is recommended to re-name the product (for example add a prefix “INVALID”), so it won’t be used in future transactions.


Why don't services show in purchasing?

Services cannot be purchased. To order a service, it is recommended to set up a non tracked product and use this then in your purchase order. To set up a non tracked product, please go to sales - products - green button - new product. Mark the product as "NO" in the field "track inventory". You will then be able to add the product into your purchase order to send the order to your supplier.

If you have any kind of service that needs to be added into a bill only, you are free to do so in the expense tab in the bill and directly select the account from your chart of accounts to have the expense posted correctly.
