The Coupa portal is an amazing example because I've had to personally spend ~10+ hours clicking that new invoice button and retyping the exact same info.
If you want to set up monthly billing in Coupa, you just manually create 12 invoices and schedule them out. Each time you have to retype all the account information from scratch, and there are a few landmine buttons on the page that will clear all the forms and make you start from scratch. I can't imagine the thousands of human hours lost every year to just filling out fields in Coupa.
Yes, it's a huge pain from what we've seen. That portal is actually running in production for some of our AR/AP AI customers, and getting browser agents to properly parse that page was difficult -- Coupa injects all the DOM elements through a JavaScript <script/> tag like 2-5 seconds after the page loads, non-deterministically. :)
