Hi desireco42,
Thanks for your comment.
The main difference is that if you go with Stripe directly, you need to integrate the checkout on your personal website, and it requires some code skills, and of course a functional website.
Instead, Wirize is a ready-built tool (basically you don't need anything I pointed out above).
Anyway, you're totally right, Stripe is very easy to use, but if you've just some one-time payment needs, maybe you don't need to set up a website just to integrate a checkout.
What do you think?
