I have some suggestion to speedup purchase invoice and sales invoice entry.
When we prepare an invoice the “account” should be selected in every line like “Inventory sale”, “Sale”.
In my case most of my sales are inventory sale. In every line I have to select the account “inventory sale”.
But it should be select automatically same account of previous line when we add new line.
Same method should be follow in tracking code entry.
We are not able to use arrow key to select inventory items in invoice. find the screen shot below
