Window Installer invoicing tips
- Print each unit's U-factor and solar heat gain coefficient, because energy tax credits and utility rebates often require them together with the product label.
- Say whether each opening was an insert or a full-frame replacement; the labor and the finished result differ, and owners comparing quotes need to know which they received.
- Made-to-measure units cannot be returned, so put the order date and a reference to the signed measurement sheet on the invoice in case a size is later questioned.
- List interior trim, painting or drywall repair as separate or excluded items, since a full-frame replacement often disturbs finished walls around the opening.
Window Installer billing disputes to head off
- A drafty window after installation leads to withheld payments. Recording the sealing method and offering a dated follow-up check gives you a clear process for complaints.
- Factory delays get blamed on the installer; noting the order date and promised ship date keeps the timeline honest.
