A Word invoice template is the right choice when you already write everything in Word, want to change the layout freely, and send a handful of invoices a month. This one is a plain .docx with no macros: a header for your business, a bill-to block, a six-row line table, totals, and a terms box. Type over the placeholders, save as PDF, send.
Free, one page, US Letter. No email, no sign-up. It opens in Word 2010 and later, in LibreOffice and in Pages, and it imports into Google Docs if you upload it to Drive.
Same layout in other formats: Fillable PDF · Excel / Sheets (.xlsx)
The layout: header, bill-to block, line table, totals, terms. Same in every format; the format changes how you fill it.

Yes: File → New and search “invoice” shows several. They are generic, often with brand placeholders and tables that are hard to resize. This template is laid out for service and trade work: separate labor and materials, a deposit line and a terms box.
Partly. Put the cursor in the total cell, Layout → Formula → =SUM(ABOVE). It recalculates only when you select the field and press F9, so check before you save as PDF. For automatic math use the Excel or Google Sheets version.
Click in the header, Insert → Pictures, then set the image to “In front of text” and drag it to the top left. Keep it under 2 inches wide so the header stays on one line.
PDF. A .docx can be edited by the recipient and renders differently on a phone. Save as PDF every time; keep the .docx as your master.
