The first thing to remember is that the Inventory movement and Inventory Location changes in Manager only affects Inventory quantiles and not the Inventory financial values. Having the Purchase Invoice dated Dec still has the financial recordings as Dec, the Manager Inventory changes doesn’t shift the financial recordings to Jan just because the delivery wasn’t until Jan
To track the Purchase Invoice Inventory separately from the physical Inventory movement you need to activate the Goods Receipts tab under Customise, below Settings.
Activating this tab causes all inventory to be “homeless” until directed to a home, by this I mean, after processing the Purchase Invoice click on the Inventory Item’s Qty value you will see a Report like below for Inventory Item ABC - waiting for delivery.
Once the goods have arrived, you would create a Goods Receipts for the Inventory Received
And this would change the Inventory Items Qty Report to the following
None of this has caused any accounting changes to the Dec dated & processed Purchase Invoice
Was the initial Sales Invoice just for the down payment (deposit request with no Inventory quantities), if yes, then there are no Inventory impacts until the final Invoice & delivery, or was the initial Sales Invoice for the full amount (all inventory quantities) but only a down payment was required until delivery, if yes, then see below.
Being an over year end transaction, the treatment depends on the significance of the transaction.
If its of low value then it would be reflected in the Inventory Item’s Qty Report as below until a Delivery Note was issued - the Delivery Note tab has to be activated to track Inventory invoicing separately from Inventory movements.
Noting that the final Sales Invoice would just be a reprint of the initial Sales Invoice but with the inclusion of the down payment.
If its of high value then consideration should be given towards making year end adjustments which transfers the sale into the following year.
