Change from Paypal to just invoice

I used an available template to create my "july stock" form it appeared not to have a payment option which is what I wanted to do because I was offering a discount and going to invoice them separately.

Please help!

I looked and it said to delete that feature but when I did it deleted ALL of my items that I put in :( (Spent hours this morning don't want to loose that)

All set cancel request I was able to switch to purchase order :)
