I'm a data analyst, I work with many ecommerce businesses from the US.
One of my expertise is Google analytics, so this should be a easy to do work. What I spealise is not just report building but also to come up with data backed actionable steps.
For many clients I work with they prefer reporting in Google data studio, which will slice and dice the data later. Also, it becomes easy to update the report easily. I have done this multiple times.
Please share the requirements, I shall give you the required output.
