Free Invoice Templates — 190+ for Every Industry

What Is an Invoice Template?

An invoice template is a pre-formatted document that captures every field a buyer expects to see on a payment request — invoice number, issue and due dates, seller and buyer details, itemized line items with quantity and rate, subtotal, tax, and total. Using a template replaces the slow process of starting each invoice from a blank page with a one-minute fill-in workflow, and keeps every invoice you send consistent with your brand and complete in the fields your accountant or your clients expect. Eonebill provides 190+ free invoice templates spanning every industry, payment model, and visual style, downloadable as PDF, Word, Excel, Google Docs, and Google Sheets without any account creation.

When to Use an Invoice Template

Reach for an invoice template whenever you bill a client for goods or services and need a paper trail that satisfies both sides — buyer accounts payable, seller bookkeeping, and the IRS Schedule C or Form 1120 line that will eventually reference the transaction. Common moments: completing a freelance project, delivering a milestone in a long contract, closing a one-off retail or e-commerce sale that needs a non-receipt invoice, or converting a quote into a formal payment request. Industry-specific variants exist for situations that share fields universally — contractor invoices need permit and job-site fields, photographer invoices need shoot-date and usage-rights fields, consultant invoices need engagement-period and hourly-rate breakdowns.

How to Create an Invoice with a Template

1. 1. Choose the template that matches your billing context. Pick industry first (contractor, freelancer, retail), then format (PDF for one-off send, Excel for formula-driven calculations, Word for collaborative editing).
2. 2. Fill in the static fields. Add your business name, address, phone, email, and (optional) logo. These remain the same on every invoice you send, so a saved template variant cuts setup time on the next bill.
3. 3. Add the buyer details and a unique invoice number. Standard formats include sequential (INV-001), year-prefixed (2026-001), and project-coded (PROJ-MAR-01). Pick one convention and stick with it for the calendar year.
4. 4. Enter line items with quantity, rate, and amount. Itemize work so the buyer can see exactly what is being charged — bundled line items invite disputes and slow payment.
5. 5. Add tax, total, and payment instructions. Specify accepted payment methods (ACH, check, card, wire), bank or portal details for ACH and wire, and the late-payment policy. Issue the invoice with a clear subject line such as Invoice INV-001 — Due March 15, 2026.
