# Missing required invoice information

Structured e-invoices need required supplier, customer, invoice header, total, and line item fields before export.

## What you may see

- Seller name is required
- Buyer name is required
- Seller country is required
- Buyer country is required
- Invoice number is required
- Invoice date is required
- Currency is required
- At least one invoice line is required

## What this means

E-invoice formats require structured data. A value that is visible in the PDF may still be missing from the extracted invoice data if the PDF layout, scan quality, or wording made it unclear.

## What to check

- Supplier legal name and address
- Customer legal name and address
- Invoice number
- Invoice issue date
- Currency
- At least one line item with name, quantity, unit, net price, and amount
