which tools are more helpful?
@sanjayb,
To create AS-IS & TO-BE you can use " Microsoft Visio" .
Let me know if you need any tools for specific usage.
In case of UIPATH, there are tools like UIPATH EXPLORER, CONNECT AND PROCESS MINING. These will help you out 
My wife is a business analyst, and she says that microsoft visio is a good program with a large set of tools. You should try it, it will come in handy. There are many things to consider when implementing a business. One of these things is a virtual addres is powered by digital mailbox technology, enabling businesses to view and manage their postal mail and packages remotely, either online or via a smartphone app. This is a physical mailing addres where postal mail or parcels from any carrier are received and stored securely. For a small fee, you can rent one or more addresses in different states and even in different countries. Believe me, this will create a professional image of your company.
