19 Free Invoice Templates
Every invoice a small business sends, pre-built: the general bills — simple, service, hourly, freelance — and the trade versions with the parts tables, permit lines, and progress math their industries actually use. Each one ships in Excel and Google Sheets with the totals computing, in Word and Google Docs for branding and typing, and as a blank PDF for the clipboard. No signup, no watermark, no account — download the file and it's yours.
Nineteen invoices, five formats each.
Invoice templates: the bill, pre-built, with the math already done.
An invoice needs to say who is billing whom, for what, for how much, and by when — and then it needs to be arithmetically right. These templates handle both halves: the layout carries the fields an invoice is expected to have, and the spreadsheet versions compute every derived number from the ones you type, so line amounts, tax, deposits, and the total can never quietly disagree.
The general templates cover most billing. The trade versions exist because trades don’t bill generically: a repair shop separates parts from labor under a VIN, a contractor states a materials markup, a construction draw computes retainage, a daycare prints the tax ID parents file with. Picking the template shaped like your billing is most of what “professional invoicing” means.
We check every spreadsheet the hard way before it ships — sample data in, computed cells read back and compared against hand-worked totals, in Excel and again after Google Sheets conversion. If a template is on this page, its math has been run.— David, Apollo’s Templates
