In short: Invoice Engine for HVAC & plumbing, Run by Reconciliation is a reconciliation engine aimed at hvac & plumbing dispatchers, covering invoicing. It scores 75/100 on AltF Ideas, carried by monetisation (96) and held back by feasibility (46). Typical pricing is $9.6k–$144k per customer per year, with a first version reachable in six to twelve months for $42k–$137k.
HVAC & plumbing teams lose invoices assembled from four systems by hand. In most hvac & plumbing businesses this job has never had software written for it. Most operators assume this is simply the cost of doing business.
Point a reconciliation engine at invoicing, and let people review output instead of producing it. Revenue is managed service, which suits a buyer who wants the cost to track the value rather than the seat count.
