A vendor can be recognized by the "identifying fields". These are fields containing unique numbers for the relevant vendor. These numbers are the IBAN number, the VAT number and the Chamber of Commerce number. However, these must be correctly entered in the master data of ISP-Invoice before the vendor can be recognized. If you notice that a vendor is not recognized, but at least one of the "identifying fields" is clearly present on the invoice, you can contact the administrator of ISP-Invoice within your company. He or she can change the master data of the vendor.
