What worries me is that the item I most know about seems like the problem statement is not that useful. The title is "early delay detection for shipments" and the text seems to mostly be about inventory (so the description is odd).

The frame is that enterprise solutions for these problems do not scale to smaller retail chains, and I find that at least believable.

The thing about this problem is that it's not hidden. It's extremely obvious. I work in SaaS targeting logistics (transportation for me, transportation, order management and warehouse management for our company), so I know a bit about this space, though I'm not in it directly. Plenty of people are solving this problem for bigger companies.

I put roughly 0% credence in the idea that many many people haven't noticed this is a problem for smaller companies. I put low credence on the idea that no one has tried to solve it for them via software. What I suspect is that this is a case where the basic idea is super-simple and obvious, but the reality of producing something that works in the market is hard.

None of that is to say that there couldn't be a real improvement here. It's just that I suspect it takes a real insight into why this problem hasn't been solved yet, and a new angle to make your solution work.
