Unless im doing something wrong, even if you put a po on a specific task in the po drop down options it doesnt deduct from the cost of the job unles you also add it the task cost in the invoice. Or if you need a po for just a random supply of anything I need it to be deducted from the invoice with out always being tied to a specific task. Just need more options and an option to just deduct a part or stock replenishment from that job.
