FAQs and troubleshooting for invoices and tax documentation

Common questions about preparing, signing, and preserving invoices for accounting and tax — with practical troubleshooting steps and clarifications.

Invoice missing tax line or incorrect tax amount
Verify the invoice template tax settings and jurisdiction. Confirm whether the tax rate is applied per line item or at the invoice total. If calculations are incorrect, update the template tax configuration and regenerate the invoice before signing to ensure accounting entries and tax reports remain accurate.
Signed invoice not visible to accounting system
Check integration logs and API credentials to ensure successful pushes. Confirm that the accounting export schedule is enabled and mapping fields match ledger account codes. Re-run the export for the affected invoice and validate receipt on the accounting side.
How long must signed invoices be retained
Retention depends on federal and state requirements, typically three to six years for tax purposes. Also review industry-specific rules and contractual obligations. Configure automated retention policies to retain, archive, or purge documents according to those timelines.
Recipient cannot apply signature on mobile device
Ensure the recipient uses a supported mobile browser or the vendor mobile app. Ask them to update the app, clear cache, or try an alternative browser. If problems persist, provide a downloadable PDF for signing and re-upload the signed file with an attached audit record.
Audit trail entries missing or incomplete
Confirm that audit logging is enabled and that system clocks are synchronized. Export the event log for the invoice and review recorded actions. Contact support if logs are truncated or events are missing for further investigation.
Correcting an already signed invoice
Do not alter a signed record; instead, issue a corrected invoice or credit memo and obtain signatures where required. Keep the original signed invoice and the corrective document together to preserve a clear audit trail for accounting and tax purposes.
