Tender Digital Signature for Secure SignNow Workflows
Award-winning eSignature solution
What a tender digital signature is
A tender digital signature is an electronic signature workflow used to send, sign, and track procurement documents with an audit trail. In SignNow, the signer can review the file, authenticate with approved methods, and apply a legally binding signature tied to the record. The platform stores timestamps, signer activity, and document history, which helps demonstrate intent, integrity, and completion under U.S. ESIGN and UETA rules.
Why it matters for U.S. transactions
A tender digital signature speeds procurement, reduces paper handling, and preserves evidence for disputes. Under ESIGN and UETA, the result is generally enforceable in U.S. business transactions when intent, consent, and attribution are documented in the signed record.

FAQ and troubleshooting
These answers cover plan limits, compliance needs, and record-handling issues that affect tender digital signature workflows in SignNow.
Check template permissions and signer routes in SignNow. Business and Business Premium cover standard sending, while Enterprise adds advanced signer authentication. If the file still fails, verify that the document is not blocked by an ESIGN or UETA exclusion.
Use the audit trail export or completed document download to confirm timestamps, signer identity steps, and document history. SignNow keeps these records with the sealed file, which supports review under ESIGN, UETA, and evidence rules.
For HIPAA workflows, SignNow can be used only with a BAA in place. The policy must also cover unique user IDs, access control, and audit controls under 45 CFR 164.312 and document retention under 45 CFR 164.530(j)(2).
If a signer cannot access the document, confirm the email address, browser, and mobile app version. SignNow supports Chrome, Firefox, Safari, Edge, iOS, and Android, so most issues come from the recipient’s settings or blocked messages.
Kiosk mode is included in Business Premium, while Enterprise adds advanced signer authentication and richer controls. If the feature is unavailable on your plan, compare the plan list before changing the workflow.
If a record must be retained for a regulated period, export the completed file and audit trail, then store them under the governing rule, such as HIPAA 45 CFR 164.530(j)(2), IRS 26 CFR 1.6001-1, or FINRA Rule 4511.
