FAQ and troubleshooting
These notes focus on plan limits, compliance requirements, and signer verification issues that matter when adding digital signatures to business documents.
If your signed PDF must support HIPAA workflows, use a SignNow plan with a BAA and retain records for 6 years under 45 CFR 164.530(j)(2). Audit trails should remain attached to the file for access review and dispute support.
If a signer needs stronger identity proofing, use two-factor authentication or ID verification. SignNow supports advanced authentication options, which help align workflows with higher-assurance use cases under NIST AAL2 expectations and sensitive transaction controls.
If bulk sending matters, Business Premium includes bulk send. Entry-level plans focus on core signing workflows, templates, and audit trails, so higher-volume distribution usually belongs on a plan with mass invitation tools.
If a document should be signed offline or on a phone, use the SignNow mobile apps for iOS or Android. Mobile signing remains valid under ESIGN and UETA when intent and consent are documented.
If you need to connect signing to CRM or ERP systems, the Enterprise and Site License options add stronger integration and API coverage. Teams often pair those plans with Salesforce, NetSuite, Microsoft 365, or Google Workspace.
If a PDF will be used in a legal dispute, keep the audit trail, timestamps, and recipient history together. That evidence helps support authentication under FRE 901 and the admissibility record needed for litigation review.

Platform support for signing
SignNow works in modern browsers on desktop and mobile devices, with mobile apps available for iOS and Android. Secure access depends on supported browser versions, device updates, and a trusted internet connection for sending, signing, and storing records.
Browsers Chrome, Firefox, Safari, and Edge. Operating systems Windows, macOS, iOS, and Android. Devices Laptop, desktop, tablet, and phone.
For managed deployments, administrators should plan for browser controls, mobile device policies, and user access rules. Teams in regulated environments may also need retention settings, SSO, API access, and certificate-related controls to match internal governance and compliance requirements.
Business types that benefit most
Different organizations use digital signatures for different volumes, approval paths, and compliance needs, so setup should match the document workload.
Solo professionals use SignNow to send contracts, NDAs, and invoices quickly, while keeping signatures, reminders, and signed copies in one place without extra administrative overhead. This is useful for consultants, brokers, and independent firms that need simple workflows and predictable pricing for routine approvals across multiple clients and deals. Growing service businesses use SignNow to standardize HR forms, consent documents, and client agreements across multiple employees. Shared templates, delegated sending, and role-based access make it easier to keep approvals moving when a coordinator, manager, or assistant handles recurring paperwork for more than one department. Enterprise teams use SignNow for higher-volume approvals, integrations, and records control. NetSuite, Salesforce, Google Workspace, and API connectivity help large organizations route documents, document actions, and preserve audit trails across finance, operations, and compliance groups without forcing everyone into a single manual signing queue.
These tasks are executed by both individual contributors and centralized administrators depending on organizational policy and required controls.
