The order form should feel safe and simple. Ask only for what you need, show what they are getting, and place trust signals near the button: guarantee, secure checkout badges and a short testimonial.
Two step order forms usually beat one step forms because the first step only asks for contact details.
Do it step by step
- Show the product image and price clearly.
- Ask for contact information first, then payment.
- Add one order bump between the card fields and the buy button.
- Restate the guarantee next to the button.
