The integration syncs instantly after a transaction takes place, or after an invoice is uploaded.
Whenever we are unable to immediately sync a transaction to your Xero account, we will attempt to do so again later that same day.
When manual sync is required
If you had already made payments before setting up your Xero connection, once you've saved the Xero settings for an application, a Sync button will appear for all the transactions under the app, allowing you to push them to Xero with your selected account and contact.
Whenever you change the Xero settings of the application, the updated Xero settings will be applied to new transactions from then on.
However, for existing transactions, we do not edit, remove, or replace the previous synced entry. If you wish to retroactively edit the Xero settings of transactions that were pushed to Xero, please edit them directly in your Xero account.
