Transform your manual invoice processing into a fully automated system that saves 5+ hours per week. This step-by-step guide shows you how to create an invoice automation workflow using Airtable and Zapier that handles everything from data entry to client notifications.
What You’ll Build
By the end of this tutorial, you’ll have:
- Email Automation: Automatically extract invoice data from emails and create records
- Data Organization: Store and organize invoice data in a structured Airtable database
- Smart Notifications: Send alerts for approvals, due dates, and payment confirmations
End Result: A complete invoice processing system that automatically captures invoice data, routes for approval, tracks payment status, and sends reminders - all without manual intervention.
Before We Start
What You’ll Need
- Airtable account (free tier works)
- Zapier account (starter plan recommended)
- Gmail or business email account
- 30 minutes of setup time
- Basic understanding of email forwarding
Expected Benefits
- Save 5+ hours per week on data entry
- Reduce invoice processing errors by 90%
- Never miss payment due dates
- Instant approval notifications
- Complete audit trail for all invoices
Step 1: Set Up Your Airtable Invoice Database
Create Your Base Structure
1. Create a New Base Log into Airtable and create a new base called “Invoice Management”. Start with a blank base rather than using a template for maximum flexibility.
2. Set Up Your Fields Create these fields in your main table:
| Field Name | Field Type | Purpose |
|---|---|---|
| Invoice Number | Single line text | Unique identifier |
| Vendor | Single line text | Company/person name |
| Amount | Currency | Invoice total |
| Due Date | Date | Payment deadline |
| Status | Single select | Pending, Approved, Paid |
| Email Content | Long text | Original email body |
| Attachments | Attachment | Invoice files |
💡 Pro Tip: For the Status field, create options: “Pending Review”, “Approved”, “Paid”, and “Rejected”. This will help you track each invoice through its lifecycle.
Step 2: Create Your Zapier Automation
Set Up the Email Trigger
1. Create a New Zap In Zapier, click “Create Zap” and choose Gmail as your trigger app. Select “New Email” as the trigger event.
2. Configure Email Filters Set up filters to only process invoice emails:
- Label: Create a “Invoices” label in Gmail
- From: Specific vendor emails (optional)
- Subject: Contains “Invoice” or “Bill”
- Has Attachment: Yes
📧 Email Setup Tip: Ask vendors to send invoices to a dedicated email address like invoices@yourcompany.com, or set up Gmail filters to automatically label invoice emails.
Add Data Processing Steps
3. Extract Key Information Add a “Format” step to extract information from the email:
- Use text parsing to find invoice numbers (regex: INV-\d+)
- Extract amounts using currency patterns ($\d+.\d+)
- Parse due dates from email content
- Clean vendor names from sender information
4. Handle Attachments Set up attachment processing to save PDF invoices:
- Check if email has attachments
- Filter for PDF or image files
- Download attachment content
- Prepare for Airtable upload
Step 3: Connect to Airtable
Create Airtable Records
5. Add Airtable Action Add Airtable as an action step and choose “Create Record”. Map your email data to Airtable fields:
| Airtable Field | Gmail Data Source | Processing |
|---|---|---|
| Invoice Number | Extracted from subject/body | Text parsing |
| Vendor | From name | Clean formatting |
| Amount | Extracted from body | Currency parsing |
| Due Date | Extracted from body | Date formatting |
| Status | Static value | ”Pending Review” |
| Email Content | Email body | Full text |
🔧 Field Mapping Tips: If data extraction isn’t perfect initially, you can always manually update records in Airtable. The key is getting the basic structure automated.
Step 4: Add Smart Notifications
Approval Notifications
6. Send Approval Alerts Add an email action to notify the approval team:
To: finance@yourcompany.com Subject: New Invoice Needs Approval: {{Invoice Number}} Body:
A new invoice has been received and needs your approval:
Invoice #: {{Invoice Number}}
Vendor: {{Vendor}}
Amount: {{Amount}}
Due Date: {{Due Date}}
View in Airtable: [Direct Link]
Please review and update the status in Airtable.Due Date Reminders
7. Create a Separate Reminder Zap Set up a second Zap for payment reminders:
- Trigger: Schedule by Zapier (daily)
- Filter: Airtable records where Due Date is in 3 days
- Action: Send reminder email
- Condition: Status is “Approved” but not “Paid”
