Can you put quantities on Free Text invoice?

I would like to record quantities within a Free Text invoice – is this possible?

thx!

You enter quantities in the Amount field on the Invoice Lines tab (if I correctly understood your question).

The amount field is the actual dollars / currency to be entered. I am looking for how to post to the Quantity field, ala on a general journal or retail sales order (units)

thanks!

You cannot do this, a free text invoice is for an amount, the quantity becomes irrelevant. If you want the quantity you need to create the invoice through the standard sales, selling an item or a service item, where the quantity becomes relevant.
