I have been running a pilot with few customers I know and fixed most of the minor issues and all are happy with the product. I was planning for a fremium model with a nominal price(compared to the existing desktop solutions price). Now when I go to other customers, they don't seem to take this application seriously because they can download the application freely and I think the price is too low(which I am working on). As a solo developer, how can I convince the customers that this is a serious application?.
Note: This is in India. Most of the customers are not very tech savvy. For payments I will have to try some offline channels.
Raise your price! I should link to a patio11 article here, probably https://training.kalzumeus.com/newsletters/archive/saas_pric... (And I just found https://stripe.com/atlas/guides/saas-pricing )
Also, a slick UI is very important for some not technical people. How does the UI of your app compare to the "standard" app?
