You can't work it out on a linear method in my book.
It is all leveraged into the customers transaction volume. So I don't think you can assume an addition of 280,000 transactions per quarter.
So in my book here are the factors:
1. The number of current live customers
2. The number of customers going live
3. The estimated number of transactions on a per customer basis
4. The increased transaction volume of each customer based on their satisfaction of the service - opening up more transactions to the ISX service.
5. The organic customer growth of each client
6. The services purchased by each customer and an estimated cost for the size of that customer.
These in my view will be the factors that should be used to estimate revenue growth.
