Please adjust the Query fields for AP invoice imports to include the payment method: Credit Card and Account to use. The Account to use would not be the bank account. It has various credit card / card holder accounts. Please view any one of our Home Depot invoices as a reference.
I was told the only work around would be to import the records as checks and manually switch the invoice payment types (Blackbaud Support Case 018933298). This seems to defeat the entire purpose of being able to upload multiple invoices.
