Digital Signature Model for SignNow
Award-winning eSignature solution
What a digital signature model means
A digital signature model is the technical and legal framework that lets a person sign a document electronically while preserving identity, intent, and document integrity. It works by linking a signer to a record through authentication, cryptographic protection, and a tamper-evident audit trail. In signNow, the process usually includes sending the document, verifying the signer, capturing the signature event, and storing evidence that shows who signed, when, and what was signed.
Why digital signatures matter
Digital signatures reduce paper handling, speed approvals, and create evidence that supports enforceability under ESIGN and UETA. For U.S. businesses, that means faster turnaround and a clearer record of consent, identity, and document integrity.
Common digital signature challenges
Signer identity can be weak if authentication relies only on email access or shared inboxes. Missing audit details can make it harder to prove intent, timing, and document integrity later. Poor retention practices can leave signed records unavailable during audits, disputes, or compliance reviews. Inconsistent workflows can create confusion when different teams use different signature methods for similar documents.

Real-world use cases
Customer stories show how digital signatures fit operational, legal, and client-facing workflows across industries.
Enterprise operations
A Xerox operations leader needed flexible routing across systems and document formats.

FAQ and troubleshooting
These answers focus on plan limits, compliance requirements, and evidence handling for U.S. eSignature workflows.
signNow Business starts at $8/user/mo with annual billing. It includes legally binding eSignatures, audit trails, templates, mobile apps, and compliance support such as ISO 27001, SOC 2, and GDPR.
signNow supports HIPAA workflows when a BAA is in place. Healthcare teams should confirm the agreement, use access controls, and keep signed records for 6 years under 45 CFR 164.530(j)(2).
For ESIGN and UETA enforceability, make sure the signer consents to electronic records, the signature is attributable, and the completed document includes a reliable audit trail.
If a document needs stronger identity proof, use advanced authentication rather than email alone. signNow workflows can support stronger signer verification for higher-risk transactions.
If a record must survive later review, download the signed file and keep the audit trail together. That evidence helps support authenticity under FRE 901 and 902.
For regulated records, confirm the plan and configuration before sending. Enterprise and Site License options can support advanced access, API use, and add-ons for HIPAA or 21 CFR Part 11 workflows.
