Why invoices fail program reviews (and how to fix it)
The most common missing information on contractor invoices—and a clean way to prevent rework.
Invoices are often the weak link. The work may be excellent—then the file stalls because the paperwork is incomplete.
Common invoice problems
- missing model numbers
- missing ENERGY STAR references where required
- generic descriptions (“window upgrade”, “heat pump install”)
- equipment combinations listed incorrectly
The clean fix
Before you approve the final invoice, ask for:
- exact make/model numbers
- rating references (where applicable)
- clear address + date + scope line items
If you want, we can provide a short “invoice requirements” checklist you can forward to contractors.
