FAQs About uploading signatures

Common questions when preparing and exporting signed documents for portal uploads and how to resolve them using signNow.

• Why is my exported PDF rejected by ICEGATE?
  Ensure the signed PDF includes all required fields and that signatures are embedded rather than appearing as separate annotations. Verify the file format accepted by ICEGATE and re-export from signNow using PDF/A if required to maintain signature integrity.
• How do I prove signer identity for customs filings?
  Use signNow’s authentication options such as access codes, two-factor authentication, or identity verification where available. Download the audit trail showing authentication method and timestamps to accompany the submission.
• Can I automate sending signed files to ICEGATE?
  Yes. Use signNow’s REST API and webhooks to automatically retrieve signed files and forward them through your integration scripts or middleware to ICEGATE’s upload endpoint or SFTP location.
• What if a signer needs to correct a signed field?
  If a document is partially signed, void the current signing session and send a corrected version for signature. signNow records the void and new signing events in the audit trail for compliance.
• Does signNow support offline signing before upload?
  Yes. The mobile app supports offline signing; signed documents sync when the device reconnects, after which you can download and upload to ICEGATE.
• How do I get help with enterprise setup?
  Contact your signNow account admin or enterprise support for assistance with SSO, API keys, or compliance configuration; enterprise plans include advanced setup assistance.

Best practices for compliant uploads

Follow these recommended practices to ensure documents exported from signNow are accepted by portals like ICEGATE and remain legally defensible.

Confirm signer identity before sending

Require authentication matching the sensitivity of the document, such as two-factor or knowledge-based checks, and document the method in the audit trail to reduce disputes.

Standardize document templates and fields

Create consistent templates with required fields and validation rules so exported signed files match the format expected by customs portals, reducing rejection rates.

Keep clear retention and access policies

Define retention schedules and role-based permissions to ensure signed documents and audit logs remain available for audits while limiting unnecessary access.

Test export and upload workflows regularly

Periodically export signed PDFs and run trial uploads to ICEGATE or your integration endpoints to verify file compatibility and update processes when portals change requirements.

Key timeframes to consider

Typical deadlines and timing considerations when collecting signatures and preparing documents for customs or regulatory submission.

Shipment documentation deadline:

Submit signed customs documents before vessel or flight cut-off times.

Audit retention deadlines:

Keep records and audit trails for legally required retention periods.

Signature completion windows:

Set signer reminders and expiration to meet filing schedules.

Export verification window:
