Common issues and FAQs for sales order invoice signing

Answers to frequent questions and steps to resolve typical issues encountered when preparing or processing a signed sales order invoice.

Why is a signature marked invalid?
Signatures can appear invalid if a document has been altered after signing, if the certificate chain cannot be validated, or if required signer authentication was not completed. Verify the final signed PDF, confirm signature validation status in the audit trail, and ensure no post-signing edits occurred.
Recipient cannot access the invoice link
Access problems often stem from expired links, incorrect email addresses, or network restrictions. Confirm the recipient address, resend a fresh signing link, check link expiration settings, and advise recipients to try an updated browser or the mobile app.
How to handle partial payments on signed invoices
Record the partial payment in your accounting system and attach a signed amendment or credit note to the original sales order invoice. Use a follow-up document that references the original invoice number and include new signed authorization if payment terms change.
What to do if a signer disputes the signature
Preserve the audit trail, export the signed packet and metadata, and review authentication evidence such as IP, MFA method, and timestamps. Escalate to legal or compliance teams with the preserved records to support dispute resolution.
How to correct an error after signing
If the signed sales order invoice contains an error, issue a corrected invoice and a brief amendment document that both parties sign. Maintain both original and corrected documents in the record with clear linking and notes in the audit trail.
Why automated reminders aren’t sending
Check workflow reminder settings, ensure email deliverability is enabled, and confirm there are no suppression rules for the recipient. Review system logs for bounce or spam reports and adjust sender configuration or DNS settings as needed.
