I need an advise for my capstone project. I'm planning to make an online booking system for a ferry company. Planning to make it for android and ios and maybe for web too. Did some research and found about ionic. Looks amazing but not sure if it's the right tech to use for my plan. Also about the payment gateway, I want the customers to pay on the app or the website directly without redirecting them to other website. Not really sure if I can use paypal with this, also i need the system to accept mastercard and visa.

I did the research, so please no hate, I'm not asking for the code. I just want to know the right tech to use. I'm just super confused and lost right now.
