If you wish not to include purchase order number in the reference field, you can opt out by doing the following (click each left tab to see the details for each step):

Login to EzzyBills, Go to Settings (mouse over the blue button with user name and expiry date, click “Settings”)
In the Settings window, Click the drop-down arrow  for “advanced settings” to expand

  • Tick “Override Purchase Keywords” option
  • Leave the text box blank, to the right of “Purchase Order Keywords”


Click “Save” (scroll down to the bottom of the user setting).

EzzyBills will assume that you do not want PO numbers to be extracted and put into the reference field in Xero.
