Optimize Your E-Signature Workflow

The workflow choices you make determine user adoption and ultimately, project success. This whitepaper offers a complete guide to building and adapting e-signature workflows across your organization

Fully Customizable


Customize the user interface of the screens to ensure a seamless mobile signing experience for your customers. This includes your preferred signature capture methods, such as hand-drawn signatures or tap-to-sign, white-labeling options, and signing workflows for multiple signers and documents.

Compare a White-labeled signing experience with no white-labeling


OneSpan Sign’s brand doesn’t appear in any of the interfaces or email notifications.  Your brand remains in the spotlight to ensure the most seamless user experience. This helps drive high adoption and transaction complete rates.


Not White-Labeled

With some e-signature vendors, their brand is part of the user experience creating confusion and risk of customers dropping off. What’s more, emails are sent from the vendor’s servers, creating the risk of phishing scams,  malware and potential lawsuits as a result.
