Invoice Processing

Starting with Aiviro version 3.28.0, we’ve introduced an improved invoice processing system that makes extracting data from invoices simpler and more powerful than ever.

Action

class aiviro.actions.reader.ProcessInvoice(filepath: Path | str)

Process invoice documents and extract structured data.

This action processes PDF invoice documents and returns a structured DocumentInvoiceV2 object containing comprehensive information including vendor details, customer data, line items, payment information, and more.

Parameters:: filepath – Path to the invoice PDF file to process
Returns:: DocumentInvoiceV2 object containing size unit, page-size, and the extracted invoice data
Example:

>>> from aiviro.actions import ProcessInvoice
>>> from aiviro.core.utils.api_client.schemas.reader import InvoiceDataV2, DocumentInvoiceV2
>>>
>>> invoice_path = "path/to/invoice.pdf"
>>> process_invoice = ProcessInvoice(filepath=invoice_path)
>>> result: DocumentInvoiceV2 = process_invoice()
>>> inv_data: InvoiceDataV2 = result.invoice_data
>>>
>>> # Access extracted data
>>> print(f"Vendor: {inv_data.vendor.name.value}")
>>> print(f"Total Amount: {inv_data.primary_total.total_amount.value}")

Note

The legacy InvoiceReader is still available via Reader for backward compatibility.

Simplified Data Access

The InvoiceDataV2 class provides a convenient dump_to_values() method that converts the entire object into a simple dictionary containing only the actual values, without the additional metadata from the FieldDataV2 wrapper:

# Convert to a plain dictionary with just the values
simple_data = result.dump_to_values()

# Access data directly with standard dictionary syntax
vendor_name = simple_data.get("vendor", {}).get("name")
total_amount = simple_data.get("primary_total", {}).get("total_amount")

print(f"Vendor Name: {vendor_name}")
print(f"Total Amount: {total_amount}")
