When the default invoicing flow for customers is set to Xero, all invoices approved for customer issuing are created in Xero. Then, depending on your settings, they will be sent for payment collection.
You can set this process up in Alguna if you want invoices to be automatically released or if you want to review them manually first.
If payments are collected through Xero, the reconciliation is automatically synced to Alguna. This means that the original payment source and the payment record are matched in both systems, keeping your invoicing reconcilation accurate in both systems.
