Under the default settings you can choose how to upload receipts.
What you are probably looking for is to upload your invoices/receipts as Purchases into Xero.
You can update your default settings to do this:
Also you can make the change for each individual receipt:
In the Veryfi mobile app:
Tap on the receipt you would like to edit
Tap on Xero Receipt Settings
Change the way you would like to upload the receipt
In the Veryfi web app:
Click on the Documents tab (left navigation menu)
Click on "View" for the receipt that needs to change
Inside the pop up you will see the "Xero Receipts Settings" tab
Make any required adjustments there
Note: It usually takes ~1-3 minutes to sync the changes from Veryfi to Xero.
