In Next, there is the option to track stock balance on items. However, the function is not comparable to a inventory management system.

You start by entering the stock balance per article manually or through the import in Price List. 
When an article is fetched from the price list to a project or work order and then invoiced, the stock balance is reduced. Please note that the reduction occurs only when you lock the invoice and that manual changes to invoice lines do not affect the stock balance.

When purchasing an article, you manually fill in the change of stock in the column Stock Balance Change, for example, if you have purchased 100 pieces, enter 100. If you need to adjust the stock balance downwards, for example, enter -50 to reduce it by 50 pieces. When you enter a value and save Stock balance change, the Stock balance is updated and Stock balance change is cleared again. In the example in the image below, the Stock balance will become 199 upon saving, and 'Change stock balance' will be blank

Stock Value List

There is a report, Stock Value List, in Price List that shows articles and their stock balance. For an article to be included in the list, there must be a stock balance noted on the article. Articles where the stock balance column is empty will not be shown in the list. It does not matter which price list the article is from. The stock value list is sorted by article number in descending order.

Columns of the Stock Value List

Stock Balance = Specified amount - invoiced amount

Withdrawn Uninvoiced = The number that has been reported on a project/work order but has not yet been invoiced. Please note that this also applies to order lines in invoice drafts (not locked invoices).

Corrected Stock Balance = Stock Balance - Withdrawn Uninvoiced

Stock Value = Cost/unit * Corrected Stock Balance
