Introduction
Creating invoices manually can be time-consuming, especially for businesses handling multiple transactions daily. Automating invoice generation in Google Sheets using Google Apps Script can streamline your workflow, minimize errors, and improve efficiency.
In this guide, we’ll walk you through how to automate invoice creation, convert it into a PDF, and even send it to customers via email—all with the power of Google Sheets automation.
Why Automate Invoice Generation?
Businesses benefit from automation in several ways:
- Time-Saving – No need to enter data manually every time.
- Accuracy – Reduces errors in calculations and formatting.
- Professionalism – Generates invoices in a standardized format.
- Easy Storage & Access – Invoices are stored digitally for future reference.
- Integration with Email – Send invoices directly to clients from Google Sheets.
If your business relies on invoicing, Google Apps Script provides a free, scalable, and efficient solution.
Step-by-Step Guide to Automating Invoices in Google Sheets
Step 1: Set Up Your Google Sheet
To begin, create a Google Sheet that will store all invoice details. You can include columns such as:
- Invoice Number
- Date
- Customer Name
- Email Address
- Item Description
- Quantity
- Unit Price
- Total Amount
This sheet will act as your invoice database, storing all the necessary information.
Step 2: Design an Invoice Template in Google Docs
Instead of manually formatting invoices, create a Google Docs template with placeholders for key invoice details.
Your invoice template should include:
- Business Name and Logo
- Customer Details (Name, Email)
- Invoice Number & Date
- Itemized List of Products or Services
- Total Amount Due
Using placeholders like {{CustomerName}} and {{InvoiceNumber}}, Google Apps Script can automatically replace them with real data from your sheet.

Step 3: Automate Invoice Generation with Google Apps Script
With Google Apps Script, you can write a simple script that:
- Fetches data from Google Sheets – Reads the latest invoice details from your sheet.
- Creates a new invoice in Google Docs – Copies the template and fills in placeholders with real data.
- Converts the invoice into a PDF – Saves it in Google Drive for easy access.
- Emails the invoice to the customer – Automatically sends the PDF invoice as an email attachment.
Once set up, this automation will generate professional invoices with just a few clicks.
Step 4: Store Invoices in Google Drive
Instead of cluttering your local system with invoices, you can save them directly in Google Drive.
- Organize invoices by date or customer name.
- Easily search and retrieve invoices when needed.
- Share invoices with team members without email attachments.
This makes it easy to track and manage all past invoices in one place.
Step 5: Automate Emailing of Invoices
Once an invoice is generated, why not send it instantly? With automation, you can:
- Send invoices to customers directly from Google Sheets.
- Customize email messages with customer names.
- Ensure timely delivery without manual follow-ups.
This seamless process improves customer experience while saving you hours of work.
Step 6: Schedule Automation for Hands-Free Invoicing
To make invoicing truly effortless, you can schedule the automation to run automatically.
- Run the script when a new invoice is added.
- Set up a trigger to generate invoices at specific times.
- Automate recurring invoices for subscription-based businesses.
With this setup, your business can send invoices without any manual effort.
