A document parser that sits beside the existing system, reads what it already produces, and closes invoicing. Aimed at solar ops teams, taking the phone queue off a human entirely.
In short: Extraction Invoice Engine for Solar is a document parser aimed at solar ops managers, covering invoicing. It scores 71/100 on AltF Ideas, carried by demand (91) and held back by moat (30). Typical pricing is $3.6k–$54k per customer per year, with a first version reachable in about a month for $7.0k–$23k.
Solar teams lose invoices assembled from four systems by hand. It is the kind of task that is too small to fund and too costly to ignore. The error rate is tolerated because measuring it would cost more than the errors.
Point a document parser at invoicing, and let people review output instead of producing it. Revenue is data subscription, which suits a buyer who wants the cost to track the value rather than the seat count.

Document parsing stopped needing per-layout templates. Solar is growing at roughly 24% a year, and this job has not been re-tooled since it was designed around paper.
| Who | The gap |
|---|---|
| A spreadsheet | The real incumbent in most of the market, and it is free |
| An offshore back office | Cheaper per hour, but does not scale down to the tail |
| An internal hire | Works until volume doubles, then breaks again |
The buying cycle is slower than the build, so runway assumptions matter more than code.
An idea you cannot act on is entertainment. Four concrete steps, wired to tools already running on AltFTool.
Score problem urgency, willingness to pay, and reachable audience size before writing any code.
