For my Open Source project jQuery Terminal I used XS:Code to manage paid support, but it really sux. I also think that the project is dead. Nothing changed no feature updates and they didn't even send an email notification when someone requested paid support. Also no per hour charge. Source: almost 3 years ago

We have 100s of different screens to migrate as well as a really large design system, and to date we've been successfully using the invisionapp.com website to keep things really well organized and easy to navigate with tags, pages, etc. We've enjoyed this system so far because it's easy for PMs and Devs to navigate in a website format, without having to learn the design software or get bogged down in artboards.
