Sending and signing methods
- Use the web app when you need to prepare, send, and monitor agreements from a desktop browser with full document controls and status tracking.
- Use the mobile app when signers or senders need to work from iOS or Android while away from the office, including camera capture and offline work.
- Use kiosk mode for in-person signing at a counter, reception desk, or event station where the device stays in place for multiple signers.
- Use shareable signing links when recipients need direct access without round-trip email coordination and you want faster completion across distributed audiences.
Browser and device support
SignNow works in modern browsers on desktop and mobile, with secure TLS connections and app support for iOS and Android.

For managed deployments, organizations usually pair supported browsers with device policies, SSO, and API access. Regulated teams should also confirm audit trail retention, certificate settings, and mobile device controls before rollout.
Document types and audiences
Independent contractors
Independent contractors use contracts, invoices, and consent forms to finalize work quickly with less paper handling.
HR teams
HR teams send onboarding forms, NDAs, and policy acknowledgments to employees and new hires.

Real-estate deeds
Workflow pain points
Users may upload a document with editable fields in the wrong places, which creates confusion and slows signer completion. Teams sometimes send to the wrong contact list when templates and recipients are not reviewed before sending. Signing requests can stall if recipients ignore email notifications, so a second reminder process is often needed. Documents with missing required fields may return incomplete records, forcing rework and delaying final approval.
FAQs and troubleshooting
These answers focus on plan limits, document rules, mobile access, and compliance details that affect everyday signing workflows.
SignNow Business includes audit trails, templates, and mobile apps. If a file is not opening for review, confirm the PDF is not corrupted and that browser support includes Chrome, Firefox, Edge, or Safari. For regulated records, keep the signed file alongside the audit trail and the applicable rule set, such as HIPAA or ESIGN/UETA.
signNow’s Business Premium plan adds bulk send and kiosk mode, while the Enterprise plan adds advanced signer authentication. If you need high-volume outreach or in-person signing stations, choose the plan that matches the workflow instead of forcing a lower tier to cover it.
For HIPAA workflows, use a BAA, access controls, encryption at rest, and an audit trail that records signer actions. Signatures alone do not make a workflow HIPAA-compliant; the surrounding handling of PHI matters as much as the signed document.
ESIGN and UETA support electronic signatures for many U.S. transactions, but wills and certain family law, deed, and court-related documents can be excluded by state law. Review the document type before sending, especially if state notarization or wet-ink execution is required.
If a signer says they never signed, the audit trail matters. SignNow records timestamps, signing events, and document history, which can support attribution and the evidentiary record under ESIGN, UETA, and FRE Rule 901/902 in court.
If a mobile signer cannot finish, verify app version, browser permissions, and device connectivity. SignNow supports iOS and Android, and some workflows can continue offline before sync. For regulated use, test the mobile path with the same controls used in production.
