Expense review handled by a document parser, with a human signing rather than writing. Aimed at hvac & plumbing field supervisors, built for one person, not a department.
In short: Expense Reviewer for HVAC & plumbing Field Supervisors is a document parser aimed at hvac & plumbing field supervisors, covering expense review. It scores 76/100 on AltF Ideas, carried by demand (95) and held back by feasibility (57). Typical pricing is $12k–$181k per customer per year, with a first version reachable in about a quarter for $18k–$51k.
HVAC & plumbing teams lose expenses approved without anyone actually reading them. It is the kind of task that is too small to fund and too costly to ignore. The cost is invisible on any P&L line, which is why it never gets fixed.
A narrow document parser scoped to expense review 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.

| Who | The gap |

| A generalist AI tool | No domain grounding, so output needs full human review |
| A spreadsheet | The real incumbent in most of the market, and it is free |
