Several years ago, I automated sending 855s using the subsystem. Now I have to automate 855s at another company and I'm not sure the built-in subsystem will work for them because of the point in the SO process they wish to send the 855.

I would love to know what other companies are doing for 855 automation? Surely there are more options now than there were in the early 2000s when we set up the subsystem.
