Getting it into Google Docs
Open Google Drive, click New and then File upload, and pick the file you just downloaded. Right click it in Drive, choose Open with, then Google Docs. Drive makes a Docs copy and the table, headings and spacing carry across. Keep that copy as your master: each time a job finishes, use File then Make a copy, and edit the copy so the original stays clean.
What is in the file
Your business block and a space for the client, invoice number, invoice date, due date and terms, an itemised table with an example line, subtotal, tax and total rows, and a notes area for how to get paid.
Sending it
Use File, then Download, then PDF Document, and send that. A Docs share link invites the client into an editable document and shows them your other revisions, which is rarely what you want on an invoice.
What Docs will not do
A Docs table holds numbers but does not add them up, so every subtotal, tax line and total is yours to type and to check. It also will not number your invoices or remember a client between jobs. When that starts to cost you time, the free invoice generator does the arithmetic, carries your details between documents and exports the same print ready PDF, and the Template Studio holds 102 editable designs.
The same template also comes as a Word file, an Excel workbook that does calculate, and a fillable PDF.
