Point a document parser at invoicing, and let people review output instead of producing it. Aimed at legal partners, built for one person, not a department.
In short: Invoice Engine Built for Partners is a document parser aimed at legal partners, covering invoicing. It scores 70/100 on AltF Ideas, carried by monetisation (92) and held back by timing (45). Typical pricing is $12k–$182k per customer per year, with a first version reachable in about a quarter for $13k–$31k.
Legal teams lose invoices assembled from four systems by hand. The work sits between two systems that were never designed to talk. 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 managed service, 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 |
| A vertical competitor | Priced and scoped for enterprise accounts, not this segment |
The data you need lives on paper in a back office; digitisation is half the product.
An idea you cannot act on is entertainment. Four concrete steps, wired to tools already running on AltFTool.
