Varun,
Veselina has touched upon an interesting point. This leads to understanding the "billing, communication and payment" process -
- What is the role of this contact person? What does s/he do (an approver, or controller or)? Why are you sending a pro forma to him/her?
- Is s/he a customer or a partner of your company?
- When does your company create a pro forma? before the real invoice?
