Can I use JotForm just as an order form but not to accept payment?

I'd like to add an order form to my website but I don't want customers to be able to pay when they order.  Is there a way to set that up?  I notice that all the order forms have at least one payment option.

Yes, you can make an order form without requiring payment. There is Purchase Order tool which collects the transaction information without any payment process. 

I hope this guide assists you:
