Waiting on a signature shouldn’t be the thing that holds up your work. Yet, for a lot of legal teams, it still is.

E-signature tools were supposed to fix that, and many have. But the real difference shows when a platform doesn’t just collect a signature but keeps the whole process clean, quick, and traceable. 

That matters when you’re handling agreements daily and need more than a basic click-to-sign tool.

In this guide, we’ll break down what e-signatures really are, how legally binding they are, and the best e-signature software that supports the way legal teams work today with features that go beyond the basics.

What Are Electronic Signatures?

Electronic signatures let you sign documents online without printing, scanning, or faxing anything. You’re working with digital documents, and the signature can be as simple as:

• Typing your name
• Clicking a button
• Drawing a signature with your mouse or finger

Some systems even support uploading a scanned signature or using a verified digital signature for added security.

They’re commonly used for contracts, agreements, NDAs, and other electronic documents that need fast turnaround and a clear record of approval.

Many electronic signature apps also track who signed what and when, which makes the signing process more secure and much easier to manage, especially for remote teams or clients.

Are Electronic Signatures Legally Binding?

Electronic signatures are legally recognized in many parts of the world, including the U.S., Canada, the U.K., and the European Union.

Laws like the ESIGN Act and eIDAS make it clear that signing digital documents carries the same legal weight as signing paper ones, as long as the intent to sign is clear and the process includes proper tracking.

Most platforms meet these legal standards by using audit trails, timestamps, identity verification, and secure document access. So whether you’re signing a basic NDA or a multi-page contract, the right e-signature tool can help you keep things legal, traceable, and enforceable.

Why Should You Use E-Signature Software?

To reiterate: being able to electronically sign and send legal documents in minutes is a major upgrade from scanning, printing, or asking for signatures manually.

But beyond speed, the right tool brings real efficiency, especially when working with legal documents, sensitive data, or handling approvals across teams.

Here are some clear benefits:

• Speed and convenience: Sign from anywhere, on any device.
• Fewer errors: Built-in checks and required fields keep the process clean.
• Security: Protects sensitive documents with encryption and access controls.
• Tracking and records: Automatically stores electronic records with full audit trails.
• Reusable templates: Save time by reusing layouts for other documents or recurring workflows.
• Unlimited documents: Many platforms let you send as many files as needed without limits.
• Workflow control: Set up custom signature workflows for multi-step or multi-signer processes.
• Advanced features: Some tools include notifications, conditional fields, and reporting dashboards.

That said, not all platforms deliver on these benefits. Some limit functionality, skip basic protections or complicate collaboration, so choosing the right e-signature tool is key.
