Create Cost of sales

Parent Previous Next

Before you start processing documents, you need to be absolutely sure that all settings for Inventory items, Cost of sales and Documents are correct.

When you first set up a Set of Books, it is important that you either enter a purchase or do a inventory take-on for each inventory item, before entering any invoices. By doing this you are giving TurboCASH the cost price of the inventory item.


The cost price is used to update the Cost of sales and Inventory accounts, when an invoice is created. Therefore, if TurboCASH does not have a cost price, the cost of sales account will be updated with a zero amount. This will cause your gross profit to be over inflated.

The required accounts and settings be absolutely correct before you proceed with purchasing and selling of trading inventory items in a Set of Books.


If this is not done, you may find incorrect results in TurboCASH. For example, the Cost of sales transactions may not be generated when documents are posted to the ledger or the cost of sales may be calculated at average cost in stead of latest cost, etc.

The option to choose which method to use - “use average cost” or “use latest cost”, setting is very important for calculating the value of your inventory.


If you are not sure whether to “use average cost” or “use latest cost”, please consult with your accountant. The value of your inventory can affect your profit and loss figures.
