Extracted Invoice Fields:

• Invoice number
• Invoice date
• Due date
• Vendor name
• Vendor address
• Customer (receiver) details
• GST/VAT number
• GST breakdown (CGST, SGST, IGST)
• Line items (product/service description, quantity, unit price)
• Subtotal amount
• Taxable value
• Discount (if any)
• Total tax amount
• Invoice total amount
• Currency type
• Purchase order (PO) number
