This is huge - get away from the tech industry and you'll find various amounts of problems to be solved, and if you can generalize it enough, you can get something successful.

Here's one I thought of and haven't found a solution for yet - a cheap "vendor portal" where vendors can submit invoices. Everything that exists apparently is enterprise and tens of thousands of dollars; which is out of reach of individuals and small businesses.

What do you mean by "vendors submit invoices", exactly? Not sure I see the value.
