I've downloaded transactions history in CSV and ZIPs with invoices. And now I'd like to bind a row from CSV to concrete invoice. I was sure that Ref ID column is referencing an invoice, but it is not true, invoice number is not equaal to Ref ID. Is it a bug or a feature ?
I can confirm that this is by design. Transaction reference numbers are different because the payment to the freelancer's account and the charge to the client's account are two different transactions.
OK, then we should be able to manually add the invoice # field as well into the report before downloading the CSV file. Otherwise providing evidence of both a statement and individual invoices will be rejected by auditors, tax authorities, whomever.
