I'm not sorry for creating a SaaS app, but I still have some doubts.

It's an MVP and I want to launch it. I haven't integrated a payment gateway yet because I want people to send me WhatsApp messages when they want to pay. I don't know if that's the right or wrong approach.

I'd also like to know if I should create an admin panel or if I can manage everything through the database.

I really don't know 😅 Any suggestions?
