Sync invoices without posting payments
By default, payments for your orders are posted to Xero and the invoice is marked Paid automatically. If your bookkeeper would rather record payments in Xero by hand - against a bank feed, for instance - you can turn that off.
Turn off Post payments to Xero on Setup - Advanced. Invoices keep syncing as normal, but no payments are posted and invoices remain Unpaid until you record them in Xero yourself.

Orders in this mode show Nothing Due in Dashboard - Orders. That means no payment was attempted - not that the invoice has been settled.
You can also turn payments off for a single payment gateway rather than the whole store, in Setup - Payouts.
