I have just used my standard letter of engagement for a FOC Independent Examination keeping everything in, you could then adjust the section on fees to reflect the subscription costs that you will be charging. Although do you need a software subscription to complete your examination?
I would guess you would do the same for your Treasurer role as you will still be providing a service, even if it's just a software subscription?
Belt and braces anyway!
Hope that helps
Thanks Karen, the charity I am doing the independent examination for want to use Xero hence subscription, I will just provide consultancy and year end review. Amending the standard letter of engagement, template found on the ICB website, is exactly what I decided to do.
