Contractor Invoice Generator FAQs
What is a contractor invoice?
A contractor invoice is a billing document used by independent contractors, construction professionals, repair specialists, and service providers to request payment for completed labor, supplied materials, equipment use, and other approved project costs.
Can I list both labor and material costs?
Yes. Each line can be categorized as labor, material, equipment, service, or another cost type. You can enter quantity or hours, the applicable rate, and whether tax applies.
Does the generator calculate tax and totals automatically?
Yes. It automatically calculates line amounts, taxable charges, subtotal, tax, discount, additional charges, total, amount paid, and the remaining balance due.
Can I use my own invoice number and purchase order number?
Yes. The invoice number, purchase order number, job number, contract reference, project name, and work location can all be customized.
Can I add my company logo?
Yes. Upload a logo image from your device. The logo appears in the live preview and is included when the invoice is printed.
Can I print the invoice on one A4 page?
Yes. The print feature opens a clean A4 print view containing only the invoice. It scales the invoice when necessary and preserves colors, borders, tables, labels, and typography.
Does it work on mobile devices?
