I built my own ERP system for handling my business. It's also an TUI and has been here on Hacker News a few times.

About training new staff, there's actually studies done on it: https://pmc.ncbi.nlm.nih.gov/articles/PMC2655855/

My 2 cents is that GUI is good for exploring new software, while TUI is wonderful if you already have a mental map of what you're doing. So for everyday used software I would definitely hope that more TUI's where used.

I made a simple biz app for a friend, with dotnet C# but as a TUI. Seemed the easiest to teach.

What a coincidence, I've just read this paper while I prepare my proposal for a PhD. I feel that the difficulties reported by the novice users were related to the peculiarities of the mainframe interfaces + the 3270 emulator. Not exactly to the fact that they were using a TUI.

Are you taking on new customers? I know a few folks hungry for old fashioned, on premises accounting and task tracking now that Intuit is pushing everyone to cloud subscriptions.

Ideally it would be a perpetual license so we can never have the rug pulled on business critical data, but I like the "x years of updates and support" model

Super interesting study. Training new staff was always the most challenging aspect of the software.
