How to Create a Fillable PDF with Electronic Signature (signNow)

TL;DR

Create a fillable PDF, add eSignature fields, and collect legally valid signatures online using signNow. The workflow covers preparing the PDF, placing form and signature fields, sending for eSign, and retaining an audit trail. signNow supports web, mobile, and API integrations and meets U.S. eSignature standards including ESIGN and UETA.

What a fillable PDF with eSignature is

A fillable PDF with an electronic signature is a digital form that people complete and sign on a computer or phone instead of printing and signing on paper. Think of it like a digital clipboard that shows fields to type in and a spot to sign with a finger or typed signature. After signing, the document locks the signature and saves who signed and when. signNow provides tools to create those fields, send for eSign, and store a secure copy with a timestamp and audit trail for legal and operational purposes.

Step-by-step: create and send

Follow these practical steps to turn a static PDF into a fillable, signable form and send it for eSignature using signNow.

  Upload Document: Open signNow, choose Upload, and select the PDF from your computer or cloud storage.
• 02
  Add Form Fields: Open the editor, choose text, checkbox, or date fields, and place them where needed.
• 03
  Place Signature Field: Drag a Signature field to the signature line so signers know where to sign.
• 04
  Send for Signature: Use Send, add signer emails and order, then include message and send the invite.

Core features for fillable PDFs

When creating a fillable PDF with eSignature, look for field editing, signer authentication, templates, and audit capabilities to ensure accuracy and legal defensibility.

Form Fields

Add text boxes, checkboxes, dropdowns, and date fields so recipients can complete required data directly inside the PDF before signing.

Signature Capture

Provide signature field options for typed, drawn, or uploaded signatures and ensure the final document locks signatures to prevent tampering after signing.

Templates

Save repeatable fillable PDFs as templates to speed recurring workflows like offer letters, NDAs, and intake forms while keeping field placement consistent.

Audit Trail

Maintain an automatic audit trail that records signer email, IP address, timestamps, and action history for legal and compliance needs.

Advanced features to consider

Beyond basic form and signature fields, advanced features improve security, automation, and integration with other business systems to scale eSignature workflows.

Bulk Send

Send the same fillable PDF to many recipients at once with individualized signing links, useful for mass acknowledgements and policy acceptance.

Conditional Fields

Show or hide fields based on previous answers to create dynamic forms that adapt to the respondent's inputs and reduce errors.

Authentication Options

Require email verification, access codes, or two-factor authentication for signers to increase signer identity assurance and compliance posture.

API Integration

Automate creation and sending of fillable PDFs through REST APIs to connect signing steps directly into CRMs, ERPs, or custom apps.

Payment Collection

Embed payment requests into contracts or invoices and collect payment during signing to finalize transactions in one workflow.

Kiosk Mode

Allow in-person signing at kiosks or shared devices while preserving audit trails and per-signer records for compliance.

FAQs About creating fillable PDFs and signing

Common questions and troubleshooting tips for creating fillable PDFs, placing signature fields, and resolving signer issues when using signNow.

• Signer did not receive email invite
  Verify the recipient email address, check spam folders, and confirm sender domain settings. If issues persist, resend the invite from the document's Manage page and provide an access code for additional security.
• Signature field not visible to signer
  Open the editor and confirm the Signature field is assigned to the correct signer role. Save the document, then preview as that signer to verify field visibility before sending.
• Need HIPAA-compliant workflow
  Execute a Business Associate Agreement (BAA) with signNow, enable required access controls, and restrict template sharing to authorized users to maintain PHI protections.
• Automating form population via API
  Use signNow REST APIs to upload documents, map JSON data to form fields, and send automated signing invites; ensure API keys and webhooks are configured securely.
• Recovering a completed signed PDF
  Locate the completed document in the signed documents folder or audit trail, download the certified PDF, and export the audit log for verification and recordkeeping.
• Managing multi-signer order errors
  Confirm signer routing order in the document settings, update signer roles if necessary, and use conditional fields to control which signers see which sections.

Best practices for fillable PDFs and eSign workflows

Adopt consistent practices to reduce errors and improve completion rates when you create fillable PDFs and collect eSignatures.
