What is AI Invoice OCR in Odoo?

AI-powered Invoice OCR (Optical Character Recognition) is a technology that scans an invoice (in PDF, image, or other formats) and automatically extracts relevant information such as:

Vendor Name and Contact Information
Invoice Number
Invoice Date
Line Item Details (Description, Quantity, Price)
Total Amount
Taxes and Discounts

The AI Invoice OCR in Odoo part refers to the use of machine learning models that improve over time, learning from previously processed invoices. This makes the extraction more accurate and adaptable to different invoice formats.

In Odoo, this technology can be used to automatically create purchase orders, bills, or journal entries from received invoices, reducing the workload of accountants and employees handling invoicing.

How AI Invoice OCR in Odoo

AI Invoice OCR in Odoo capabilities for invoice processing, using external services like Odoo’s own Document Management module or third-party solutions such as Google Vision API or Tesseract OCR. These tools enable automatic extraction of data from incoming invoices, which can then be used to create purchase orders, vendor bills, and accounting entries.

Steps in the OCR Process:

Capture the Invoice: The invoice is uploaded to Odoo, either manually or via email, where it is processed.
Text Extraction: The OCR engine scans the document, detecting text, and identifying key data points (such as dates, vendor names, and amounts).
Data Mapping: The extracted data is mapped to the relevant fields in Odoo (such as the vendor, product, date, amount, etc.).
Review and Validation: The extracted data is reviewed by a user or a validation system to ensure its accuracy.
Record Creation: Once validated, the invoice is automatically converted into an Odoo journal entry, purchase order, or bill.

How to Set Up AI Invoice OCR in Odoo

Odoo includes native support for OCR, specifically through the Document Management module, which can extract information from invoices and other documents. Additionally, you can integrate third-party OCR engines like Tesseract or use AI tools such as Google Vision API or AWS Textract for more advanced use cases.

Let’s walk through a basic setup using Odoo’s built-in OCR capabilities and integrate it with the invoice processing workflow.

Step 1: Install the Required Odoo Modules

To begin using Odoo’s built-in Document Management features, you’ll need to install the following modules:

Odoo Document Management Module:
- Go to the Odoo Apps menu.
- Search for Document Management.
- Install the module.
Invoicing Module:
- Install the Invoicing or Accounting module if you have not already done so.

Step 2: Enable OCR in Odoo

Once the Document Management module is installed, you will need to enable OCR. You can do this by configuring the OCR settings in Odoo.

Go to Settings > General Settings.
Under the Document Management section, enable OCR for Documents.
Make sure that the Automatic Document Processing feature is turned on.

This will allow Odoo to automatically process incoming documents and extract text from them.

Step 3: Upload Invoices for OCR Processing

Now that OCR is enabled, you can start uploading invoices.

Go to the Documents app in Odoo.
Click Create to upload an invoice (PDF or image file).
Odoo will automatically attempt to read the document using the built-in OCR system.
The extracted data (vendor name, invoice number, date, total amount) will be populated in the document’s form view.
You can validate and confirm the extracted data, and Odoo will then create a vendor bill automatically.

Code Example: Integrating Google Vision API for Invoice OCR

If you need more advanced OCR capabilities, you can integrate third-party APIs like Google Vision for more accurate extraction of invoice data. Below is an example of how you can use Google Vision API to extract text from an invoice and use it in Odoo.

Install the Google Vision API Client Library:First, install the required dependencies for Google Vision:

bash

pip install google-cloud-vision
Integrate Google Vision API with Odoo:

Here is an example of how to integrate Google Vision into Odoo for extracting invoice text:

python

from google.cloud import vision

from odoo import models, fields, api

from odoo.exceptions import UserError

class InvoiceOCR(models.Model):
_name = ‘invoice.ocr’
_description = ‘Invoice OCR Integration’invoice_file = fields.Binary(‘Invoice File’, required=True)
extracted_text = fields.Text(‘Extracted Text’)

@api.model
def extract_invoice_text(self, invoice_file):
# Initialize Google Vision client
client = vision.ImageAnnotatorClient()

# Create an image object from the invoice file
image = vision.Image(content=invoice_file)

# Perform text detection on the image
response = client.text_detection(image=image)
texts = response.text_annotations

# If OCR fails, raise an error
if not texts:
raise UserError(‘No text found in the invoice!’)

# Extract the main text from the result
extracted_text = texts[0].description
return extracted_text

def process_invoice(self):
# Get the extracted text from the uploaded invoice file
extracted_text = self.extract_invoice_text(self.invoice_file)

# Populate the extracted text into the model
self.extracted_text = extracted_text

# Further processing can be done here, e.g., creating a vendor bill
# Based on extracted text, you could map fields like total amount, vendor, etc.
# Example: Create a vendor bill based on extracted data (this is a simplified version)
vendor_bill = self.env[‘account.bill’].create({
‘vendor_id’: 1, # Assume vendor ID is extracted from the OCR text
‘amount_total’: 1000.0, # This should be extracted from the text
‘invoice_date’: fields.Date.today(),
})
return vendor_bill

Key Steps in the Code:

Google Vision API: This uses Google’s cloud Vision API to detect text in the uploaded invoice image or PDF.
Text Extraction: It extracts the text and processes it within Odoo.
Vendor Bill Creation: After extracting data (e.g., vendor, total amount), a vendor bill is created in Odoo.

Make sure to configure the Google Cloud Vision API credentials before using it. You can get the credentials from the Google Cloud Console.
