Startup Idea: Universal Tax Software Interface

Startup idea to create a software that allows accountants to access different tax software systems using a single application. The software should be capable of opening accounts and exporting all the data into a PDF or Excel spreadsheet, eliminating the need for multiple accounts.

I am an accountant and I have many different clients that use different tax software.

This is annoying as I have to create a new account for every single software as I cannot have one account and use it on everything.

I need a program opens these accounts and exports all the information into a PDF or Excel spreadsheet, so I do not have to create a new account just to view the information.
