Unable to Convert Custom Invoice Template

[rupesh881]

I'm working on customizing the invoice template for the invoice extraction process, but I'm unable to extract the expected fields from the attached PDF using the custom template.

Input PDF

sample.pdf

Expecting Output jsut like

	"fields": {
		"invoice_number": "AUTOSAL4406",
		"proforma_invoice_date": "26/12/2024",
		"order_number": "AUTOSAL4406",
		"order_date": "26/12/2024",
		"seller_details": {
			"name": "Impex",
			"address": "Noida, Uttar Pradesh, INDIA",
			"ABN": "4589",
			"email": "[email protected]"
		},
		"buyer_details": {
			"name": "Tester Edit",
			"email": "[email protected]",
			"address": "ABU DHABI"
		},
		"country_of_origin": "NOIDA, INDIA",
		"country_of_final_destination": "AUSTRALIA",
		"port_of_loading": "Noida, Uttar Pradesh",
		"port_of_discharge": "BRISBANE",
		"items": [
			{
				"container_number": "1",
				"packing_qty": "3.00",
				"description": "This is a text",
				"HS_code": "57021000",
				"unit_price": "234.00",
				"total_price": "702.00"
			},
			{
				"container_number": "1",
				"packing_qty": "3.00",
				"description": "This is a text",
				"HS_code": "57021000",
				"unit_price": "234.00",
				"total_price": "702.00"
			}
		],
		"total_price_AUD": "1,404.00",
		"tolerance": "This product belongs to impex docs",
	},
}

My Current Template is

issuer: Impex

  invoice_number: "PROFORMA INVOICE NUMBER AND DATE\\s+PAGE NUMBER\\s+([A-Za-z0-9]+)"
  date: "26/12/2024"

  seller_abn: "ABN:\\s*([0-9]+)"
  amount: "TOTAL\\s+.*?AUD\\s*([\\d,]+\\.\\d{2})"
  tolerance: "TOLERANCE\\s*:\\s*(.*?)\\s*(?=PAYMENT TERMS)"
  payment_terms: "PAYMENT TERMS\\s*:\\s*(.*?)\\s*(?=SPECIFICATION)"
  specification: "SPECIFICATION\\s*:\\s*(.*?)\\s*(?=WE CONFIRM)"
  origin_confirmation: "WE CONFIRM GOODS ARE OF AUSTRALIAN ORIGIN"

tables:
  - start: "DESCRIPTION OF GOODS"
    end: "TOTAL"
    body: "1\\s+This product.*?\\s+(?P<qty>\\d+\\.\\d+)\\s+(?P<description>This is a text)\\s+(?P<hs_code>57021000)\\s+(?P<unit_price>234\\.00)\\s+(?P<line_total>702\\.00)"
options:
  currency: AUD
  decimal_separator: "."

  - "PROFORMA INVOICE"

Hey @bosd / @m3nu / @alexis-via ,

Thanks so much for creating this fantastic library!

I'm currently struggling with creating a custom template as described above. Despite my efforts, I'm not able to achieve the expected output from the invoice extraction process. Would you mind guiding me on how to adjust the template to correctly extract the fields I need?

Your help would be greatly appreciated!

Thanks in advance!

You may have more luck here when using the lines parser..

lines: - start: "DESCRIPTION OF GOODS" end: "TOTAL" body: "1\s+This product.*?\s+(?P\d+\.\d+)\s+(?PThis is a text)\s+(?P<hs_code>57021000)\s+(?P<unit_price>234\.00)\s+(?P<line_total>702\.00)"
