I am making a SAAS webapp, it's basically an invoice generator for freelancers in which they will have to chat with a chatbot, the chatbot will ask questions like your GST if you have, your address, what service you've provided to the customer etc. by this it will generate the clean invoice which the freelancer can give to his/her customers.
I just wanted to know that is it a good idea, should i continue doing this?
If you guys have more suggestions regarding SAAS webapps please let me know, i am open for new ideas.
