💡 Why Automate Invoice Processing?

Time is money! 💰 Manual invoice entry is slow, tedious, and error-prone. Automating this process frees you up to focus on what matters – growing your business. Plus, it minimizes errors and provides instant access to financial data.

🗄️ Setting Up Your Invoice Parsing System

This system uses Make.com (formerly Integromat), PDF parsing tools (like pdf.co), and OpenAI’s GPT-4 to create a seamless workflow.

1. Watch for New Invoices:

Use Google Drive integration in Make.com to monitor a designated folder for new PDF invoices.
Set the trigger to “Watch Files” by created time to only process new uploads.
Pro Tip: Limit the initial file processing to one at a time for easier debugging.

2. Download and Parse:

Use the Google Drive “Download a File” module to retrieve the PDF.
Send the downloaded PDF to a PDF parsing service (pdf.co or similar). This extracts key data.
Surprising Fact: PDF parsing tools can handle a wide range of invoice formats, reducing manual formatting headaches.🤯

3. AI-Powered Refinement:

Use OpenAI’s GPT-4 to enhance the extracted data. This helps to:
- Infer missing information (like vendor country).
- Standardize formats (like dates and currencies).
- Handle variations in invoice layouts.
Practical Tip: Use a clear and specific prompt in GPT-4 to get the best results. Include examples of the desired output format.

4. Google Sheets Integration:

Use the Google Sheets “Add a Row” module to populate your sheet with the extracted and refined data.
Map the extracted fields to the corresponding columns in your sheet.
Pro Tip: Bold the header row for clarity.

📄 Handling Scanned Invoices

Scanned invoices can be tricky because the text isn’t machine-readable. Here’s the solution:

1. Conditional Routing:

Use a router in Make.com to check if the PDF parsing service successfully extracted data.
If not, route the invoice to a separate processing path for scanned documents.

2. Image Conversion:

Convert the scanned PDF to an image format (like PNG) using a PDF to image conversion tool.

3. OpenAI Vision API:

Use OpenAI’s Vision API (part of GPT-4) to extract data from the image.
Practical Tip: Provide clear instructions and examples in your prompt to guide the AI.

💌 Automating Email Intake

Take automation to the next level by fetching invoices directly from your email:

1. Watch for Emails:

Use the Gmail “Watch Emails” module in Make.com to monitor your inbox for new invoices.
Use Gmail filters to target specific emails (e.g., containing the word “invoice” or a specific label).
Pro Tip: Mark emails as read after processing to keep your inbox organized.

2. Save Attachments:

Extract attachments from the emails and save them to your designated Google Drive folder.
Surprising Fact: This simple setup can save hours each week by eliminating manual downloading and filing. 😲
