Frequently Asked Questions
How should trade contractors calculate material markup percentages?
Most trade contractors (HVAC, electrical, plumbing) apply a sliding markup scale: lower-cost hardware under $50 typically carries a 50% to 100% markup to cover purchasing trips and warehousing, while major equipment (such as heat pumps or electrical panels over $1,000) carries a 20% to 35% markup.
Does this template support mechanics' lien compliance?
Yes. The invoice includes explicit property address fields, job description itemization, completion dates, and a statutory disclaimer notice required by state mechanics' lien statutes when establishing an enforceable paper trail for unpaid balances.
Can I customize company logos and hourly rates?
Absolutely. The template is 100% unlocked in native Microsoft Excel (.xlsx) format. You can replace the company header with your own business logo, adjust labor rates, edit payment terms, or add your state contractor license number in seconds.
