A narrow workflow engine scoped to invoicing alone — no platform, no migration, no six-month rollout. Aimed at energy compliance leads, replacing the spreadsheet that currently holds it together.
In short: Energy Invoice Engine on Workflow is a workflow engine aimed at energy compliance leads, covering invoicing. It scores 72/100 on AltF Ideas, carried by feasibility (91) and held back by monetisation (42). Typical pricing is $11k–$110k per customer per year, with a first version reachable in a weekend for $2.0k–$6.0k.
Energy teams lose invoices assembled from four systems by hand. Nobody owns this process, which is exactly why it keeps breaking. The backlog only surfaces when a customer or an auditor finds it first.
A narrow workflow engine scoped to invoicing alone — no platform, no migration, no six-month rollout. Revenue is site licence, which suits a buyer who wants the cost to track the value rather than the seat count.

Connectors exist for systems that were closed five years ago. Energy is growing at roughly 18% a year, and this job has not been re-tooled since it was designed around paper.
| Who | The gap |
|---|---|
| An internal hire | Works until volume doubles, then breaks again |
| An offshore back office | Cheaper per hour, but does not scale down to the tail |
| A spreadsheet | The real incumbent in most of the market, and it is free |
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.
