White-Label eSignature Built Into Your Product

Embed signing, document requests, and template editing directly into your application

Make eSignature Fit Seamlessly Into Your Product

Let users prepare, send, and sign documents without leaving your application, with an experience that matches your product, brand, and workflow.

Signing Without Redirects

Recipients can review and sign documents directly on your website or in your application, with a white-labeled experience that matches your product and brand.

Prepare and Send Documents Inside Your Product

Users can prepare documents, add recipients and fields, and send signature requests without leaving their application. Control how documents are sent and downloaded, and assign document ownership without setting up users.

Edit Templates Inside Your Product

Users can create and edit reusable templates directly inside your application, including template settings and preferences that carry through to documents created from those templates.

White-Label the Experience

Use your own logo, colors, button styles, and custom URLs so the eSignature experience looks and feels like part of your product.

Set Branding Dynamically

Use API apps to manage different branding configurations or to set logos, colors, and other branding elements dynamically in the same API request used to create a document.

Custom Requesters

Let your application send documents on behalf of different people without creating a separate SignWell account for every sender.

Add eSignature Without Building It Yourself

Adding eSignature to your product means more than adding a signature field to a PDF.

SignWell handles signing, document preparation, template editing, notifications, audit trails, document security, and the underlying eSignature functionality behind your integration.

Your team can focus on the product your customers use instead of building and maintaining a separate eSignature system.

Compliance and Security Behind Your Embedded Experience

SignWell provides the legal, security, and audit controls behind the embedded signing experience, so you do not have to build them from scratch.

  • Legally Binding eSignatures SignWell supports major U.S. and European electronic signature requirements, including ESIGN, UETA, and eIDAS.
  • SOC 2 Type II SignWell is SOC 2 Type II compliant and independently audited for security, availability, and confidentiality.
  • HIPAA and BAAs SignWell is HIPAA-compliant, and paid customers can request a Business Associate Agreement.
  • GDPR SignWell is GDPR compliant.
  • Audit Trails and Tamper-Evident Records Completed documents include detailed audit trails and tamper-evident records that capture key signing activity.
  • Encryption SignWell encrypts data at rest and in transit.

Predictable API Pricing as Usage Grows

You can see SignWell’s standard API pricing before committing engineering resources to an integration.

Paid SignWell plans include 25 API documents per month. Additional usage starts at $0.85 per API document and decreases with monthly volume, down to $0.20 per document, and is lower on high-volume and custom plans.

Standard usage-based API plans have no seat limits or monthly minimums.

Unused Prepaid Credits Roll Over

Unused prepaid API credits roll over, so the document volume you have already paid for is not lost at the end of a billing period.

Companies That Built With SignWell

Pactly

Pactly wanted customers to execute contracts without leaving its contract-management platform.

After integrating SignWell, customers could send contracts for signature directly inside Pactly. One enterprise customer migrated from DocuSign to Pactly’s embedded SignWell solution, handling more than 1,000 contracts per year.

Ivan Rawtaer Co-Founder, Pactly

Compliable

Compliable needed eSignature to work as part of its licensing and compliance platform, but its previous Adobe Sign integration introduced processing delays, API constraints, and higher per-signature costs.

Compliable completed its SignWell integration within days and reported significantly faster document processing after the move.
