Transferring invoices
To transfer straight away, go to Finance → Invoices, tick the invoices, and choose Transfer to QuickBooks from Bulk actions. Transferred invoices show an In QuickBooks badge.Cancelled and refunded invoices
Transfer the credit note first, then the invoice:- Cancelled, unpaid — QuickBooks links the credit note to the invoice, closes it, and shows the invoice as paid.
- Cancelled, paid — QuickBooks creates a credit note that stays unapplied, as the credit can still be used.
- Refunded — QuickBooks records an invoice, a payment, and a refund rather than a credit note.
Troubleshooting
Failed transfers are listed under Finance → Invoices → QuickBooks errors.Related
