Buy a Digital Signature With SignNow
Award-winning eSignature solution
What a digital signature is and how it works
A digital signature is a cryptographic method for signing electronic documents that helps verify who signed, protect the document from changes, and support legal enforceability. In practice, the signer uses a private key to create a signature tied to the document’s contents, while recipients verify it with the matching public key. In the U.S., this process supports electronic agreements, approvals, and records by linking identity, intent, and integrity in a way that is easier to track than paper signatures.
Why a digital signature matters
A digital signature speeds approvals, reduces paper handling, and creates stronger evidence of who signed and when. Under ESIGN and UETA, it can support enforceable electronic records when consent, intent, and attribution are documented.
Common digital signature challenges
Signer identity can be weak if authentication relies only on email access or a shared inbox. Documents may be disputed when the audit trail does not clearly show intent, timestamps, and device data. Compliance gaps appear when retention rules, consent records, or BAA requirements are not configured correctly. Teams lose time when signature requests, reminders, and document routing are handled outside one workflow.
Who uses digital signatures
Legal teams
Legal teams use digital signatures for contracts, approvals, and role-based signing order.
Regulated operations
Healthcare and finance teams use them for patient forms, disclosures, and regulated approvals.
Typical users and personas
At Tech Data, Bob Dutkowsky described signNow as helping improve internal and external customer service while increasing speed to revenue. That fits operations leaders who need faster contract turnaround across sales, finance, and customer workflows without adding paper steps or manual routing. At Xerox, Kodi-Marie Evans said signNow gave the team flexibility to get the right signatures on the right documents in the right formats through NetSuite integration. That matches enterprise operations teams managing document variation, approval rules, and system-connected signing processes.

Key features for digital signatures
signNow supports digital signature workflows that focus on identity, document integrity, and practical control across teams and regulated use cases.
Audit-ready records
Create signing workflows that capture intent, timestamps, and document history in one record, making it easier to track approvals and support enforceability under U.S. eSignature rules.
Reusable templates
Use reusable templates for recurring agreements, forms, and approvals so teams can send the same document structure without rebuilding each request.
Signing order
Route documents in a set order when multiple people must review, sign, or approve before completion.
Mobile signing
Collect signatures on phones, tablets, and desktops so remote staff can complete documents without waiting for office access.
Identity checks
Apply signer authentication options that help match the right person to the right document before signing begins.
Workflow tracking
Keep signed files organized with document history, reminders, and completion status visible in one place.
How digital signatures work
The signing flow links the signer, the document, and the record history in a sequence that can be reviewed later.
Open document: The signer opens the document and reviews the request. Verify signer: Identity is verified with the selected authentication method. Sign electronically: The signer applies a digital signature to the record. Seal and record: The system seals the file and stores the audit trail.

Recommended workflow setup
A practical setup balances identity assurance, record integrity, and retention rules for U.S. business and regulated workflows.
| Setting | Recommendation |
|---|---|
| Authentication method | SMS OTP for routine approvals |
| Signature type | SES for standard U.S. contracts |
| Audit trail | Enable full event logging |
| Document retention | 6 years for HIPAA records |
| Encryption | TLS 1.2/1.3 and AES-256 |
Platform and device requirements
signNow works in modern browsers and mobile apps, with secure connections required for document access and signing.
Desktop browsers Chrome, Firefox, Edge, and Safari on Windows and macOS. Mobile devices iOS and Android mobile apps for signing on phones and tablets. Connection security TLS 1.2 or TLS 1.3 with current browser versions.
For enterprise deployments, managed devices, SSO, and API access can be added to fit controlled environments. Regulated teams should also confirm retention, authentication, and encryption settings before rollout.

Real-world use cases
Customer stories show how signNow fits operational workflows where speed, control, and system integration matter.
Enterprise operations
Tech Data used signNow to improve internal and external customer service.
- Speed to revenue improved.
- Integration supported existing workflows.
The result was faster document movement across teams, with less manual handling and better alignment between customer service and revenue workflows. That kind of use case fits organizations that need connected approvals rather than isolated signing steps.
NetSuite operations
Xerox used signNow with NetSuite to route the right signatures to the right documents.
- Right format, right document.
- NetSuite integration added flexibility.
The result was more control over document routing and format handling inside an enterprise system. That matters when teams need signing to follow business rules, not just collect a signature quickly.
Best practices for implementation
A careful setup helps teams keep signatures defensible, organized, and aligned with the document type being signed.

FAQ and troubleshooting
These answers focus on plan limits, compliance settings, and signNow features that affect digital signature workflows in U.S. business use.
signNow Business includes legally binding eSignatures, audit trails, templates, and mobile apps. If you need HIPAA support, confirm a BAA is in place and keep retention aligned to 6 years under 45 CFR §164.530(j)(2).
Bulk send is included in signNow Business Premium. If you do not see it, check your plan tier and account permissions. Enterprise and Site License options add more controls for larger deployments.
HIPAA workflows require a BAA and controls for user identification, integrity, and audit logging under 45 CFR §164.312. signNow supports HIPAA use when configured correctly, but the account must be set up for PHI handling.
For 21 CFR Part 11 use cases, you need validation, secure audit trails, and unique signer identification. signNow’s regulated workflows should be reviewed against your quality system before use in FDA-covered records.
If a signer cannot open the document on mobile, confirm they are using a current version of Chrome, Safari, Edge, Firefox, iOS, or Android. Signatures created on mobile remain valid under ESIGN and UETA when intent and attribution are clear.
If a document looks altered after signing, use the audit trail and document history to verify whether the file was changed after completion. Tamper-evident records help show whether the signed version remained intact.
