Design matters when it comes to professional HVAC invoices

Your invoice design should be easy for clients to understand—especially when billing includes diagnostics, parts and labor, and variable hourly rates.

Use simple fonts, bold your total amount due, and separate labor and materials. Include service dates and job notes to eliminate confusion. A well-structured contractor invoice ensures faster approvals and payments.

Tofu makes the invoicing process easy with invoice templates that offer clarity and a professional look for every completed job.
