Digital Signature vs. Electronic Signature for SignNow
Award-winning eSignature solution
What a digital signature means
A digital signature is a type of electronic signature that uses cryptography to prove who signed a document and whether the document changed after signing. In U.S. business use, the key question is not just how the signature looks, but whether you can show intent, identity, and integrity. SignNow records signer actions, timestamps, and audit data so completed files can support internal controls, legal review, and regulated workflows under ESIGN and UETA.
Legal standing in U.S. business
Under ESIGN and UETA, an electronic signature is generally admissible if you can show attribution, intent, and a reliable record of the signing process. Wills and certain court orders are excluded, so document type still matters.

The process moves from preparation to delivery, signing, and final storage with a record of each action.
Set up: Prepare the file and define the signing order. Deliver: Send the document and track delivery. Sign: Collect signatures and record the completion event. Finish: Store the final PDF with its audit trail.
Sending and signing methods
- Use the web app when you need guided routing, templates, and role-based signing inside a browser session for office workflows and review-heavy documents.
- Use the mobile app when signers must complete forms on iOS or Android while away from a desk, including field, retail, and travel scenarios.
- Use kiosk mode when multiple people sign from one secured device at a front desk, branch office, or service counter with supervised access.
- Use shareable signing links when you need a simple way to request signatures from external parties without creating extra internal steps for them.
Who uses eSignatures and why
Business teams
Contracts, NDAs, and client approvals move faster when legal, finance, and operations teams need signed records with clear consent and audit history.
Operations teams
HR forms, patient consents, and release forms stay organized when staff need mobile signing, role-based access, and retention controls.
Business types that benefit most
Different business types use eSignatures for different document volumes, compliance needs, and approval speeds.
Solo real estate brokerages use lease packets, disclosures, and addenda to keep closings moving without printing, scanning, or office visits, which is useful when sellers and buyers are remote or on tight timelines. Healthcare clinics use patient intake, consent, and release forms with HIPAA-aware workflows so front-desk staff can collect signatures on desktop or mobile devices and keep records organized for retention needs. Construction businesses sign bids, change orders, and subcontractor agreements on site or in the office, which reduces delays when project managers need fast turnaround and clear version control across crews.
These tasks are executed by both individual contributors and centralized administrators depending on organizational policy and required controls.
Users, roles, and permissions
Administrators use SignNow to set templates, manage access, and delegate sending without giving every user the same permissions. Team managers rely on shared templates and role-specific routing so approvals stay controlled while documents move faster through the organization.
Recordkeeping practices that hold up
Retention and audit controls matter when signed records may need to be reviewed, reproduced, or defended later.
Export records together
Match retention to law
Secure archival
Preserve signing evidence
Privacy and disclosure pitfalls
Personal data can appear in signatures, attachments, and supporting forms unless access controls limit who can view each document. Consent capture can fail when the sender does not record the recipient’s agreement to electronic delivery and signing. Shared inboxes can create access control mistakes that blur who opened, signed, or forwarded the document. Retention gaps can leave signed files without enough context to explain the transaction or prove the signer’s intent.

FAQ and troubleshooting
These answers focus on signing issues, plan limits, and compliance questions that affect real workflows.
Business Premium includes bulk send, so this limitation usually means the account is on a lower plan. If you need higher-volume routing, SignNow Business Premium or Enterprise is the relevant upgrade path.
SignNow supports audit trails, timestamps, and downloaded completion PDFs. If the record looks incomplete, check whether the signing link was finished and whether the signed file or history export was archived after completion.
For HIPAA workflows, SignNow can support compliance when the organization has a signed BAA and uses appropriate access controls. HIPAA itself requires safeguards, including user identification, integrity controls, and audit controls.
If signer identity needs stronger proof, use advanced authentication options such as SMS OTP or ID verification, and pair them with the completed audit trail for attribution evidence under ESIGN and UETA.
For regulated records, retention should follow the governing rule, not the software alone. SignNow can preserve completed files, but your policy must name the retention period, such as 6 years for HIPAA records.
SignNow mobile apps allow signing on iOS and Android, while browser workflows work on desktop. If a file will not open, confirm the browser, device permissions, and PDF format before retrying.
