Hello there, Hope you're doing well!
We are team of Full Stack Developers and Designers, We have checked the Description and We are confident to take care of all your requirements.
What we can do is we can develop Separate module for this requirement, which works with Tally data, Cause Tally does not provide Customized Solution. We can treat this as an individual App, which will use Tally's data by export function.
Let's connect on chat and discuss further.
Thanks & Regards,
Sudhan.
