Use the recorded status and History to see what happened to an invoice.
1. Open the invoice
Go to Invoicing → Invoices and open the intended document. Confirm its customer and current status.
2. Open History
Select History in the editor. Review the recorded issue, email, customer-view, and payment events available for this document.
3. Interpret each event
Sent or a queued email describes a delivery step. Viewed records the customer view being opened. Neither event means the invoice was paid.
4. Verify payment separately
Open Manage Payments → History for the actual recorded receipts and remaining balance. If a send outcome is uncertain, keep its reference and use the review action or support before sending again.
