Invoicing handled by a reconciliation engine, with a human signing rather than writing. Aimed at construction estimators, finding what the inspector would find, first.
In short: Construction Invoice Engine is a reconciliation engine aimed at construction estimators, covering invoicing. It scores 77/100 on AltF Ideas, carried by demand (95) and held back by feasibility (53). Typical pricing is $4.1k–$61k per customer per year, with a first version reachable in six to twelve months for $42k–$145k.
Construction teams lose invoices assembled from four systems by hand. A typical construction operation runs this on people, memory, and a shared spreadsheet. Most operators assume this is simply the cost of doing business.
A reconciliation engine that handles invoicing end to end and hands a human the exceptions rather than the queue. Revenue is data subscription, which suits a buyer who wants the cost to track the value rather than the seat count.

| Who | The gap |
|---|---|
| An offshore back office | Cheaper per hour, but does not scale down to the tail |
| 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 |
The incumbent is a person, and displacing a person is a change-management problem.
An idea you cannot act on is entertainment. Four concrete steps, wired to tools already running on AltFTool.
