If you haven't set up your payment methods and bank accounts, it is highly possible to see this error in your Inbox.
Setting up payment methods is necessary because at Dext we pull across information about your bank accounts and you can easily export items there for reconciliation.
It's never too late to fill in this gap, however!
Simply head to the 'Sidebar menu' and open the 'Lists' tab. Under 'Payment methods' select an existing bank account from the drop-down menus.
While you are here, you can also set some rules based on payment methods.
