We have a supplier that acts as an intermediary for other suppliers who are providing a service. We have to create individual supplier records for these suppliers (due to tax reporting), and will receive a CSV file from the intermediary with all of the invoice details for each supplier, which we hope to use to create individual invoices for each of the suppliers using the invoice upload functionality. The intermediary is paid and not the supplier, but that we can accomplish by sharing the bank account accross all of them.
What would be the most efficient/easiest way to create the supplier records from the CSV file? I imagine we will be creating quite few new ones every time we receive the CSV file.
