Free Service Invoice Template for Contractors

Getting paid on time starts with a clear, professional invoice. Many service contractors still rely on handwritten tickets or generic spreadsheets that miss critical details like material markups, labor breakdowns, and warranty terms. This free service invoice template is designed specifically for field service businesses including plumbing, HVAC, electrical, and general contracting companies. It includes sections for itemized labor with hourly rates, a material and parts list with cost and markup columns, applicable taxes and permit fees, payment terms and accepted methods, and your company branding. A well-structured invoice reduces disputes, speeds up payment collection, and presents your business as polished and trustworthy. Whether you are billing a residential homeowner or a commercial property manager, this template adapts to both scenarios. Use it as a starting point and customize it to match your specific trade and pricing model.

Start by adding your company logo, name, license number, and contact information to the header. For each job, fill in the customer details and service address. List labor line items with a description of work performed, hours spent, and your hourly rate. Add materials in a separate section with unit cost and any markup. The template automatically structures these into a clean subtotal, tax, and total due. Set your payment terms — most contractors use Net 15 or Net 30 — and note your accepted payment methods. Print or email the completed invoice to your customer. Save a copy for your records and follow up if payment is not received by the due date.
