# Invoices failed to sync or export
Invoice export problems are usually caused by authorization, mapping, status, or duplicate-record conditions. Diagnose the source record before retrying so the external system is not sent a second invoice.
This article preserves the original help URL and now reflects the current TimeSentry workflow.
Identify the stage that failed
Separate the problem into one of four stages:
- **Authorization:** the provider did not grant or retain access.
- **Connection:** TimeSentry cannot use the saved external account.
- **Mapping:** a TimeSentry record is not linked to the correct external record.
- **Synchronization:** an import or export failed, is delayed, or returned a partial result.
Record the active company, integration, connection name, operation, time, affected record, and full error message.
Check scope and mappings
Verify that the active TimeSentry company and external company, tenant, workspace, or account match. Inspect client/customer, project/matter, account/category, employee, and status mappings relevant to the operation. A successful connection cannot compensate for a missing or incorrect mapping.
Prevent duplicates
When a result is uncertain, do not immediately retry. Search TimeSentry and the external service using stable identifiers such as invoice number, date, amount, customer, or project. Look for an external link or synchronization identifier on the TimeSentry record. Retry only after determining that the earlier operation did not succeed.
Reauthorize carefully
Confirm provider account status, required admin consent, and plan access. If access was revoked or expired, reconnect the same intended account. Removing and recreating a connection can separate it from existing mappings, so capture the current configuration first.
Escalate with useful evidence
Provide the connection name, external organization, exact action, timestamp and time zone, affected record IDs or URLs, error text, and whether the record exists in either system. Do not send passwords, API secrets, authorization codes, or full access tokens.
