What SignNow does

Electronic signature service providers let organizations send documents, collect signatures, and store signed records in a digital workflow. SignNow supports this process by letting senders prepare a file, assign signers, track status, and keep an audit trail of actions. In the U.S., the core legal framework is ESIGN and UETA, so the key questions are consent, attribution, intent, and record retention, not paper ink.

Why the legal framework matters

Under ESIGN and UETA, electronic signatures are generally enforceable for U.S. business transactions when the signer’s intent, attribution, and record integrity are preserved. A provider matters because it helps capture those records consistently, while wills and certain court orders remain outside the usual scope of electronic signing.

How the signing flow works

The workflow moves from document preparation to recipient routing, then to signing and archival, with records preserved for later review.

  • Prepare: Upload or create a document in the SignNow workflow.
  • Route: Assign recipients and set the signing order.
  • Sign: Signer reviews, signs, and receives a completed copy.
  • Archive: Store the executed file with its audit trail.

Ways to send and sign

  1. Upload a document in the web app when teams need browser-based sending, template reuse, and centralized review before signatures are requested.
  2. Use the mobile app when signers need to complete forms, approve documents, or sign on iOS or Android away from a desk.
  3. Choose kiosk mode for in-person signing at reception desks, job sites, or service counters where multiple visitors sign one device.
  4. Share a signing link when external recipients need fast access without account creation, inbox routing, or a separate document distribution step.

Connected workflows that reduce manual reentry

Connected apps move signed data into existing systems, reduce duplicate entry, and keep teams working inside the tools they already use for sales, operations, and storage.

Documents teams complete with SignNow

Commercial teams

Contracts, NDAs, and invoices move faster for sales, finance, and procurement teams that need simple routing and clear sign-off records.

HR and operations

HR forms, consent forms, and policy acknowledgments help onboarding teams collect employee signatures while keeping records organized for audits.

Who benefits most from SignNow

Different business types use SignNow for different documents, but the main goal stays the same: a signed record that is easy to route and store.

  • Solo law practices use eSignature workflows for client agreements, intake forms, and approvals that need quick turnaround without paper handling or repeated office visits.
  • Healthcare groups use signed intake, consent, and release forms with HIPAA-aware controls, BAA coverage, and audit trails that support recordkeeping requirements.
  • Construction firms use mobile signing for bids, change orders, and site approvals when project teams need signatures without returning to the office.

These tasks are executed by both individual contributors and centralized administrators depending on organizational policy and required controls.

Processing stages for signatures

The sequence below shows how a document moves from preparation to storage after signatures are collected.

01

Document preparation

Prepare the document from a template or uploaded file and verify fields before sending.
02

Delivery to signers

Deliver the request by email, link, or app routing, depending on signer access.
03

Signer turnaround

Most signers can complete in minutes or hours, depending on review steps.
04

Completion and archival

Archive the executed file and its audit trail together for later retrieval.

Five retention rules to know

Retention periods depend on the record type and the rule that governs it, so the workflow should keep the executed file and its evidence together.

01

6 years for HIPAA records

HIPAA 45 CFR 164.530(j)(2) requires 6 years for signed PHI records.
02

6 years for FINRA records

FINRA Rule 4511 requires 6 years for certain broker-dealer records.
03

Tax record retention

IRS 26 CFR 1.6001-1 generally requires tax records to be kept.
04

SEC record retention

SEC Rule 17a-4 governs broker-dealer record preservation and retention.
05

FERPA record retention

FERPA records follow education retention policies plus applicable institutional rules.

Retention and record-keeping basics

Recordkeeping matters when signatures need to stand up to audits, legal review, or internal policy checks across U.S. business workflows.

Follow covered-record retention

Keep HIPAA-related signed records for 6 years under 45 CFR 164.530(j)(2), and store the matching audit trail with the final PDF so the transaction can be reconstructed later.

Export every audit trail

Export the audit trail after completion and save it with the executed document, signer history, timestamps, and delivery evidence in a secure archive with controlled access.

Archive completed files securely

Use encrypted storage and role-based access for completed agreements, especially when documents contain PHI, PII, or financial data that may need restricted retrieval.

Set clear retention rules

Apply a documented retention schedule for invoices, HR forms, and contracts, then delete records only after legal hold and policy checks are complete.

What the audit trail records

The audit trail shows how a signed document can be traced from first delivery through final completion and export.

01

Signer authentication:

Capture the signer’s identity and log the method used.
02

Timestamp capture:

Record the exact time of each action in UTC.
03

Document hashing:

Create a hash that ties the record to content.
04

Tamper-evident sealing:

Seal the file so later edits break validation.
05

Evidence storage:

Keep signer history, delivery data, and device details.
06

Trail export:

Export the audit trail with the executed document.

Risks to watch

Missing consent

Document may be unenforceable.

Weak audit trail

Evidence may be disputed.

Excluded document type

Record may be rejected.

Notarization required

Filing may fail.

Real-estate mismatch

Deed may not record.

Privacy and disclosure pitfalls

  • Personal data can appear inside signed files, so sharing links and recipient permissions need to be limited before documents leave the sender’s control.
  • Consent capture can be missed when users skip the electronic disclosure step, which can weaken enforceability for records that require explicit electronic agreement.
  • Access control mistakes can expose completed agreements, especially when shared folders or broad admin rights are used without role-based restrictions.
  • Record retention can be inconsistent when teams save executed files in multiple systems without a single archival rule or audit trail export.

Browser and device support

SignNow works in current desktop and mobile browsers, with TLS protecting sessions and native apps available for iOS and Android.

  • Browser support Chrome, Firefox, Safari, and Edge work in modern versions.
  • Operating systems Windows, macOS, iOS, and Android are supported.
  • Security layer TLS 1.2 or later required.

For regulated and enterprise deployments, managed devices, SSO provisioning, API access, and certificate-based workflows may matter more than device type. The practical requirement is a supported browser or app, plus account controls that match the organization’s security and retention policy.

Frequently asked questions and fixes

These answers focus on SignNow features, plan limits, and U.S. compliance rules that affect signature workflows and enforceability.

Check whether the recipient is using a Business or higher plan if bulk sending, kiosk mode, or advanced signer authentication is missing. Business Premium adds bulk send and kiosk mode, while Enterprise adds advanced signer authentication. HIPAA workflows also require a BAA and the appropriate controls.

Verify that the signature was completed inside the full signing workflow and that the document history is intact. SignNow audit trails capture timestamps, signer actions, and delivery evidence, which helps support ESIGN and UETA enforceability if a document is later challenged.

For healthcare files, confirm a BAA is in place before handling PHI. HIPAA does not require electronic signatures specifically, but it does require access controls, integrity controls, audit controls, and unique user identification under 45 CFR 164.312.

If the issue is a mobile signing failure, use the SignNow mobile app on iOS or Android and confirm the document is not restricted by device policy. Mobile signing remains valid under ESIGN and UETA when intent and attribution are preserved.

For federal or regulated records, match the workflow to the relevant standard. 21 CFR Part 11 requires secure audit trails, unique credentials, and time-stamped records; records containing PHI must follow HIPAA retention rules and secure access requirements.

If a counterparty questions legal validity, check consent, identity verification, and the preserved copy of the executed record. ESIGN and UETA support electronic signatures, but excluded documents such as wills and certain court orders still need different handling.
