Point a document parser at invoicing, and let people review output instead of producing it. Aimed at solar owner-operators, taking the phone queue off a human entirely.
In short: Solar Invoice Engine on Extraction is a document parser aimed at solar owner-operators, covering invoicing. It scores 73/100 on AltF Ideas, carried by demand (92) and held back by open field (38). Typical pricing is $2.0k–$41k per customer per year, with a first version reachable in about a month for $7.0k–$21k.
Solar teams lose invoices assembled from four systems by hand. Every solar team solves this the same way: someone stays late. The cost is invisible on any P&L line, which is why it never gets fixed.
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. 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 |
|---|---|
| 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 |
| The incumbent suite | Sells a platform; this job is one neglected module inside it |
Trust has to be earned before anyone lets this run unsupervised.
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.
→ AltF IdeaLabAsk how they handle this today and what it costs them. If nobody can quantify the pain, the demand score is optimistic.
→ Survey BuilderCheck availability, DNS, and email authentication in one pass so your first outreach lands in an inbox.
→ AltF DomainOpsStand up intake, the review queue, and billing before you build the clever part.
