What happens when I cancel an Invoice? 

Tax Invoice and External Invoice: 

When you cancel a Tax Invoice or External Invoice in AgriDigital, it will be automatically voided in your XERO account. 

Cancelling Tax Invoices with AgriDigital's Xero Integration

RCTIs: 

Individual RCTIs cannot be cancelled in AgriDigital, the Payment Summary is cancelled. With Xero Integration, when a Payment Summary is cancelled the associated XERO RCTIs will be marked as Void. 

NOTE: If the RCTI in XERO is already Void, you will receive an error in AgriDigital to notify you that the RCTI could not be cancelled.
