A bank on Intuit's list is not automatically a Web Connect bank
QuickBooks Desktop downloads its own directory of financial institutions, with entries that specify how each institution connects. At the last count, 5,800 entries were flagged for Web Connect, the route a .qbo file takes, while 2,588 entries were Direct Connect only. Direct Connect is a live link your bank enables for the account, sometimes as a paid service. If your bank is listed but the import refuses your file, check which connection its entry supports.
