1. Connect Gmail
Sign in with the Gmail account you want to use for sending invoices and saving files to Google Drive. Approve Gmail send and Drive file access.
How it works
Simple invoicing with tools you already use
Super Simple Invoice is a minimal invoice creator for Gmail users. It prepares a clean PDF, stores it in your own Google Drive, and sends it from your own Gmail account when requested.
2. Complete first-time settings
Enter your company details, currency, taxes, default products and services, email template, and default Google Drive destination. The default folder is Super Simple Invoice.
3. Create the invoice
Enter the customer, items, quantities and rates. You can use an earlier invoice date; a new non-sequential invoice number is created automatically.
4. Choose email recipients
Send the PDF to the customer, your connected Gmail account, the company email, or any combination of those options.
5. Review, then save or send
Preview the final PDF first. Then save it to Google Drive only, or send it from Gmail and save it to Drive in one step. Each Gmail account can generate up to 10 invoices per day.
Where your information goes
Invoice PDFs are stored in the Google Drive destination you select. The service stores your Gmail account email, encrypted Google authorization credentials, reusable settings, and basic saved/sent usage counts. It does not maintain a separate customer database; customer details are used to create the current PDF and email.
