Always wonder why Shopify is needed. In my case a lot of banks provide consistent APIs or buttons for payments. Numerous providers that aggregate those APIs, but no one forcing You. No need to pay middleman
Most require programming skills (and then you are the one that need to make it secure) or use a CMS plugin (WordPress) and then you are back where Shopify fish for customers.
I use to run our businesses webshop with my own code but having less time to keep up on it I gave up and switched to OSS CMS instead. Not Shopify though as they take (at least back when I checked) a huge chunk of money for the service. I can't remember the amount but it was something like 3%? For a medium business that's enough to hire developers to create your own! Now I use a payment provider (bank) instead and it costs nothing except the payment processor fee I already had to pay.
