When I am doing any new implementation in NAV I always recommend that expected costs are switched on in Inventory set up. What is the benefit?
When switched on and you ship stock out or receive stock in NAV, postings are made to an interim account automatically, so NAV is doing your accruals for you!
With this switched on we are getting extra postings in NAV, so I always use this diagram to talk through where postings go to:
There are reports that can be produced in NAV such as ‘Stock received not invoiced’ and ‘Stock shipped not invoiced’, these should then match to these GL interim accounts if the posting setup is right.
You can also run your inventory valuation report and include these expected costs on the inventory valuation report.
