We have just released a feature that will allow invoices and payments created before the initial Xero integration date to be pushed across to Xero.
1. Go to Settings > Integrations and select "Synchronise from previous date" in the Xero section.
2. Select the initial date.
3. Select the "Synchronise previous information to Xero" button.
We also fixed a few issues in this release:
- When syncing a payment that was split between multiple invoices, some times, only one invoice on Xero would receive this payment, this has been fixed.
- When adding a payment to an invoice that was not synced to Xero yet, this payment was not being synced, now we sync both the invoice and the payment to Xero.
