With this release we have improved the way we are handling syncing invoices from a previous date. Previously some customers were experiencing issues where not all invoices were showing up in Xero due to limits with the Xero API. This release addresses this issue.
If you have run into issues with syncing previous invoices, please follow these steps to run another sync: https://cliniko.zendesk.com/entries/22290449-Automatically-synchronise-past-invoices-and-payments-with-Xero
We are committed to making our Xero integration the best it can be! We would love to hear your feedback, and if you're able to help us out a little bit, it would be much appreciated if you'd write a nice review over on the Xero Addon Review page: https://community.xero.com/business/discussion/2783477/
