FAQ

Does adding more security make the process harder for the client?

Not necessarily. ZapSign lets you add layers of security intelligently, applying authentication based on the document's risk level or criticality.

This makes it possible to reinforce trust in sensitive processes, like client onboarding, contract renewals, or dispute filings, without adding unnecessary steps to simpler journeys. The goal is to increase security without turning the signature into a barrier for the client.

Can e-signature reduce friction in the client journey?

Yes. With ZapSign, clients can sign documents digitally, quickly and intuitively, without printing, scanning, traveling, or relying on manual processes.

This reduces delays, doubts, and drop-offs during key steps in the journey, such as contract execution, proposal acceptance, document delivery, and case filing. In practice, the firm gains operational efficiency while offering a simpler, more convenient experience to the client.

Can ZapSign help increase conversion on digital processes?

Yes. By reducing manual steps and letting clients sign documents quickly, securely, and intuitively, ZapSign helps cut down on bottlenecks that can delay or stall an engagement.

With less friction, more clients tend to complete proposals, acceptances, renewals, and other digital processes within the expected timeframe.

Does the client need to download an app or create an account to sign?

No. Signing can be done simply, via a link, directly in the browser on a phone or computer. Or the digital signature can be integrated into your own client portal or app, making the process even smoother.

This lowers barriers to access and avoids steps that could cause drop-off, especially in sensitive journeys where speed and simplicity are essential for conversion.

Is it possible to integrate with legal or case management systems?

Yes. ZapSign has a flexible API for integration with case management systems, CRMs, client portals, internal tools, and onboarding, engagement, renewal, or filing workflows.

This lets e-signature be built directly into the processes your team already uses, without requiring abrupt changes to team routines or the client experience.

With the integration, you can automate sends, track signature status, reduce manual tasks, and keep documents connected to the firm's ecosystem.

How does ZapSign help reduce fraud?

ZapSign lets you add layers of security to the signing process, such as multi-factor authentication, biometrics, identity validation, and technical evidence recorded throughout the journey.

In practice, this helps confirm that the person signing really is who they say they are, and creates records that strengthen traceability during audits, disputes, or internal reviews.

All of this can be applied without turning the signature into a complex journey for the client, keeping the balance between security, speed, and experience.

Does the solution support high-volume operations?

Yes. ZapSign was built to support operations with a high volume of documents, signatures, and users, while maintaining stability, security, and performance.

This makes it possible to scale workflows like contract issuance, proposals, renewals, terms, filings, and agreements without a proportional increase in operational effort.

On top of that, features like bulk signature, workflow automation, real-time reporting, and API integration help teams gain productivity without losing control, traceability, or governance.
