I have been a software developer for over 20 years, and Core's payment system is used by my healthcare provider. It is always a horrid experience.

I could tell the developers were rookies right away when I saw this message where you enter your medical record number: "Please do not include leading zeros." It not only contains a misspelling, but if you can't write code that removes leading zeroes from a number in an html form, you should not be writing code. Inexperienced coders are infamous for fixing bugs by adding notes to the user interface.

I am going to urge my provider to demand fixes. Their Core payment system is totally unacceptable.
