Electronic Signature Logbook 21 CFR Part 11 for SignNow

What an electronic signature logbook under 21 CFR Part 11 means
An electronic signature logbook under 21 CFR Part 11 is a controlled record of who signed, what was signed, when it was signed, and why the signature was applied. In regulated U.S. settings, it helps electronic records stand in for paper records by preserving identity, intent, and a secure history of actions. With signNow, the workflow typically includes signer authentication, timestamped signature events, audit trail capture, and retention of the signed document and related metadata for review or export.
Why it matters for compliance and enforceability
It reduces manual handling, speeds approvals, and supports admissibility under ESIGN and UETA when identity, intent, and record integrity are documented. In FDA-regulated workflows, it also helps support Part 11 expectations for traceable, defensible records.

Common Part 11 implementation pitfalls
Missing signer authentication details can weaken attribution and make the signature harder to defend in an audit or dispute. Incomplete audit trails leave gaps in who acted, when they acted, and what changed in the record. Poor retention rules can break document history, especially when records must be preserved for regulated review periods. Weak user provisioning can create shared access, which undermines unique signer accountability and Part 11 controls.
Who uses it and where it applies

Key features for regulated signing
signNow supports controlled signing workflows that preserve identity, timing, and document history for regulated U.S. recordkeeping needs.
Audit trail
Captures signer identity, timestamps, and document history in one record, helping teams review approvals without rebuilding the signing sequence later.
Signer control
Supports controlled access and signer verification, which helps regulated teams document who signed and how the signature was authorized.
Record retention
Keeps signed records organized for later review, export, or retention workflows tied to FDA and internal policy needs.
Mobile signing
Works across desktop and mobile signing flows, which helps distributed teams complete approvals without printing or scanning.
Workflow routing
Reduces manual routing by sending documents directly to signers and preserving the approval path in a searchable record.
Compliance support
Supports compliance-oriented document handling for U.S. regulated use cases where traceability and integrity matter.
How the signing flow works
The process follows a controlled sequence that ties identity, action, and record history together for later review.
Authenticate: The signer receives a controlled request with identity checks. Capture: The system records the signature event and timestamp. Log: The document history stores actions in a tamper-evident trail. Retain: The signed record remains available for review and export.

FAQ and troubleshooting
These answers focus on plan limits, compliance controls, and recordkeeping details that matter in regulated signing workflows.
signNow Business includes legally binding eSignatures, audit trails, templates, and mobile apps. For HIPAA workflows, use a BAA and keep the signed record history available for review.
The 7-day free trial lets you test signing workflows without a credit card. It is useful for setup validation, but regulated production use should rely on a paid plan with retention and access controls.
Bulk send is included in Business Premium. If you need controlled routing for many recipients, that plan reduces manual sending while keeping document history and signer tracking in place.
signNow supports audit trails that record signer activity, timestamps, and document history. That evidence helps support ESIGN, UETA, and 21 CFR Part 11 review needs.
HIPAA support requires a BAA. signNow states HIPAA compliance with BAA required, so healthcare teams should confirm the agreement before handling PHI.
The Enterprise plan adds advanced signer authentication, formula fields, and conditional fields. For stricter regulated workflows, those controls can help structure approvals and reduce manual errors.
