Do you have an app of the program? You see there are over 89% of population nowadays use their cell phones for communication and purchase. I believe it would be more convenient

I have just finished creation of my own apps and could advise a mobile app developer, it is Rubygarage (if interested it is their website
https://rubygarage.org/services/mobile-app-development) They provide iOS and Android mobile application development services so you can reach your customers on their favorite devices. Hope it would help you
Cheers
And let the panic be in the past!
