Email your invoices without typing a single email.

Still sending invoices by hand? Find the PDF, look up the email, write a message, attach the file, press send. Then repeat.

Plainflow Invoice Emailer does it for you. Drop an invoice PDF into a folder and it emails the right customer from your own Gmail.

HOW IT WORKS

1. Name each file with its invoice number, like INV-1001.pdf
2. List invoice number, customer name and email in the sheet
3. Drop the PDF into your Inbox folder
4. It finds the customer, writes the email, attaches the PDF and sends it
5. The file moves to Done and a log records it

BUILT TO BE SAFE
• Starts in practice mode: Gmail drafts only, nothing is sent until you switch it on
• Problem files (unknown invoice, bad email, duplicate) go to a Review folder, not to customers
• It remembers what it already handled

WHAT YOU GET
• Google Sheet with the tool built in
• Fake sample invoices and customer list to practice with
• Step-by-step setup guide with screenshots
• Troubleshooting page

GOOD TO KNOW
• Works with Gmail and Google Sheets; best with a normal Gmail account
• Google limits daily emails, so it suits small businesses
• Google shows an “unverified app” screen once; the guide shows what to click
• Files must be named with the invoice number; it can’t read numbers inside scanned images yet
• It doesn’t create invoices or track payments
