Some questions about integration and postal code verification

Hello there!

I’m looking for some tool to make inbuilt invoice system for client’s web site. After looking thorught speciefic invoice wp plugins I realized that they are not able to fit into current website’s page layout, so I switched to payment form plugins in my research.

I want to build invoice system myself with help of some cpt and custom fields.
I need a payment form plugin thich is able to:
use single form for all posts but pass different price to pay value into form (based on custom field, so I need some hook or inbuild fuctionality for this)
stripe payment system support + provide postal code for additional stripe validation
Is it possible?
