If some data is not synced to Xero it is possible to synchronise invoices and payments over past dates.
Please note, there is maximum limit of 3000 invoices that can be synced per account in one day. If you need to sync more than this, please contact support@nookal.com

1. Go to Setup > Connections > Integrations > Configure Xero.
2. Click on the Xero account to access the setup page.
3. Click on the Tools tab.
4. Select the Dates From and To.
5. Click Enqueue Request.
It can take a few hours for the data to be synced.
