Invoicing handled by a document parser, with a human signing rather than writing. Aimed at legal partners, so the work stops following people home.
In short: Invoice Engine for Legal, Run by Extraction is a document parser aimed at legal partners, covering invoicing. It scores 70/100 on AltF Ideas, carried by feasibility (89) and held back by open field (40). Typical pricing is $2.8k–$56k per customer per year, with a first version reachable in a weekend for $2.0k–$5.0k.
Legal 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 backlog only surfaces when a customer or an auditor finds it first.
A narrow document parser scoped to invoicing alone — no platform, no migration, no six-month rollout. Revenue is usage-based, which suits a buyer who wants the cost to track the value rather than the seat count.

Document parsing stopped needing per-layout templates. Legal is growing at roughly 12% a year, and this job has not been re-tooled since it was designed around paper.
| Who | The gap |
|---|---|
| A generalist AI tool | No domain grounding, so output needs full human review |
| An internal hire | Works until volume doubles, then breaks again |
| The incumbent suite | Sells a platform; this job is one neglected module inside it |
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.
