Hi Employer,
I read and understand your requirement for creating a custom excel formula, which will provide results based on the revenue forecast units. I reckon, I can do this project in a better way.
As of me, I have a good knowledge and expertise in creating codes based on VBA. You can see my Excel Add-on created by me in my portfolio.
As an additional feature, I can create an Excel Add-on with the requested excel custom function, which can be used by any other person.
Hope, we can have a discussion, if you have any clarification.
Thanks for the opportunity, and awaiting for your project acceptance.
