The "Client information" and "Supplier information" fields on the invoice upload form are reserved for B2B companies, both the buyer and the seller must have a business identifier (VAT number, SIREN, NIF, etc).
If our PDF reader (OCR) didn't correctly read the counterparty details details from the invoice you uploaded, you will have to override the information manually:
Counterpart name
Country
Business identifier
Business identifier type (SIREN / SIRET etc)
To avoid any input errors, we recommend that you copy and paste the company information directly from:
https://www.pappers.fr/ for French buyers or sellers
https://www.einforma.com/ for Spanish buyers or sellers
Informations are prefilled if detected by OCR
You can add a counterparty if needed
