How to request an instant pro-forma invoice


At Gas Cage Shop we understand the importance of a fast turnaround when an item is urgently required.

We now offer an instant pro-forma invoice service which will immediately email you a pro-forma invoice (PDF format) with your required products itemised including all the necessary information to allow you to make BACS payment straight away. 


  1. Add required items to the BASKET.
  2. View BASKET and then proceed to CHECKOUT.
  3. Enter delivery/billing address details.
  4. Finally click REQUEST PRO-FORMA INVOICE rather than PROCEED TO PAYMENT button.

Your pro-forma invoice will then be automatically generated and emailed to you within seconds!
