Please find below the business justification for my request. I addressed it to you some time ago, but I am sure you still remember. I hope you will find it strong enough in order to take all the necessary measures to make it come true. The future collaboration with this client depends on this deal. We will not lose him, but it will be very difficult to get him on our side in the future.
I am counting on a fast action from your side!
Thank you for the support and collaboration!
