Digital Signature Software

By Ivan Stevanović February 8, 2021

Digital signature software relies on cryptography to facilitate safe and verified electronic document signing. It’s a modern alternative to signing paper documents.

Old-fashioned signing is slow because documents must be laboriously prepared and mailed. Sometimes interested parties must travel to sign the papers, which is time-consuming and expensive. Paper signing is prone to errors and it creates workflow bottlenecks. It’s no wonder so many companies are turning to digital signing as a more affordable, efficient, and reliable process.

Many digital signature software solutions compete for corporate adoption. Some work alone, while others are embedded in comprehensive document management systems. We’ve identified the best of the best and prepared this review to show you the strengths and weaknesses of each.

Digital signatures versus electronic signatures

Although the terms digital signature and electronic signature are often used interchangeably, in practical and legal terms, they are not the same.

An electronic signature is any signature in electronic form. Simply typing your name into an online form or drawing your signature with your fingers is all you must do. An electronic signature carries no proof of authentication or document integrity. While it’s a fine way to end an email to your mother, it’s not suitable for contracts and other business documents.

With the digital signing of documents, you must prove your identity by providing a private key before you can affix your e-signature to a document. When you digitally sign the document, your information is encrypted and embedded in the document. This verifies your identity more uniquely than your written signature, which is why banks and countless other businesses accept digital signatures in place of signed paper documents.

Digital signatures rely on asymmetric cryptography, in which a private key is employed to create the signature and a public key is available for reading and verifying it. As long as the signer’s private key is uncompromised, the signature is legitimate. Digital signing software makes sure of that.

Here are our evaluations of the market’s top digital signing solutions.

With a user base of hundreds of millions, DocuSign is the digital signature market’s best-known brand. The company offers both free and paid versions of its eSignature program.

DocuSign eSignature is also part of the Agreement Cloud, a suite for 12 applications for analyzing, creating, and concluding business agreements.

Features

Digital signature software reviews always include DocuSign products, and for good reason. The company’s eSignature app includes practically everything you might need.

Every action you take occurs within the eSignature online dashboard, which is accessible on desktop, laptop, and mobile devices. Once you are logged in, you create a document to be signed by using a template or marking up an existing document with tags that indicate places where you want the recipient to put in information: signature, company name, personal details, and so forth.

Unlike many entry-level digital signature applications, eSignature is not exclusively digital signature PDF software. It accepts practically all file types, including Microsoft Word and Excel. Of course, eSignature works with PDFs as well. It can even detect and tag fill-in fields automatically.

Once you’ve prepared the document, eSignature can email it for you. Just provide the email addresses of the intended recipients and click Send. Once signers receive the email, a hyperlink directs them to an identity-verification page and a page that helps them create an electronic signature.

eSignature notifies you of the status of your document at every stage: when the email is received, when the recipient visits the website, and when the document is signed. You can also set up reminders and alerts for yourself and the signer. One reason DocuSign reviews are so positive is that documents signed with eSignature are fully compliant with ESIGN, UETA, and eIDAS, and are therefore legally binding in most countries.

DocuSign employs advanced security measures and observes strict privacy standards to protect your data. Document signing is available in 43 languages, and you can send documents in 13 of them. You can use collected data and previous documents to make new agreements efficiently – that’s a big time-saver. Additionally, eSignature integrates with more than 350 widely used business programs, including CRM systems and HR apps.

DocuSign software for electronic signing is one of the 12 programs included in the DocuSign Agreement Cloud, a suite of tools for streamlining the creation, dissemination, and signing process for business documents. The multitude of features and capabilities this platform provides regularly puts it on the first spot in many top lists.

Pricing

The DocuSign free plan lets you create an electronic signature and sign an unlimited number of documents. It doesn’t let you create documents or distribute them to signers, however. For that, you need to subscribe to one of the paid plans.

eSignature service plans come in four versions: Personal, Standard, Business Pro, and Advanced Solutions.

The $10 per month Personal plan is for a single user. It lets you create an unlimited number of documents. You can embed fields for users to fill in information and of course, the documents can be digitally signed. Access to the handy eSignature mobile app is also included. The $10 version of eSignature doesn’t email agreements to signers, however. That capability will cost you an extra $5 per month.

The Standard signature software plan will set you back $25 per user each month. It allows you to create and send an unlimited number of documents for signing. It also lets you set up, personalize emails and documents with your company’s branding materials, and collect comments on documents.

The monthly charge for eSignature’s Business Pro edition costs $40 per user and it adds a selection of very useful features to the mix. eSignature Business Pro lets you collect payments through e-signatures, create smart data-collection forms, receive attachments that signers add to documents, and import a list of recipients and send unique forms to each one.

eSignature Advanced Solutions is an electronic signature software package appropriate for large enterprises. The features include API documentation so you can integrate digital signing into your company’s software. It also includes single sign-on for users, advanced identification and authentication features, document automation capabilities, and much more. If you think this is right for your company, contact DocuSign and the sales department will generate you a quote based on your company’s needs.

Final thoughts

DocuSign eSignature delivers full-fledged digital signature services via well-structured plans for companies of all sizes. The number of useful features makes eSignature a strong contender in the battle to name the market’s best signature software.

PandaDoc’s digital software solution began as a specialized program geared toward the particular needs of sales organizations. Digital signing was just part of that solution, which provided a full suite of helpful features for sales professionals and their managers.

That explains why PandaDoc is still more than a digital signature software company today. For sales organizations, PandaDoc is a useful central software hub. The program retains its specialized features for collecting e-signatures on sales documents and a wide variety of special capabilities for streamlining the sales process. It allows you to quickly and easily create sales documents, contracts, and quotes. You can customize agreements, track customer engagement, and extract customer data from the market’s most widely used CRM systems.

Features

At PandaDoc’s core is the ability to create and collect verified e-signatures. Documents signed through the PandaDoc system are legally binding in most countries due to their compliance with ESIGN and UETA regulations. However, this document signing software company suggests that you seek legal counsel before undertaking international transactions, as the company can guarantee lawfulness only for US-based transactions.

PandaDoc features an easy-to-use drag-and-drop editor that allows you to quickly create proposals, quotes, and contracts – everything you might need to quickly close deals with customers and clients. The software also automates the signing process, allowing signers to quickly review, accept, and sign proposals. PandaDoc allows free document signing for customers through any desktop, laptop, or mobile device, further streamlining the process.

The PandaDoc platform also supports collaboration with advanced features. During our PandaDoc review, we could freely add comments, mark parts of the agreement, track changes, and more. These features support the sales process by letting you and your customers negotiate together.

All PandaDoc documents are fully customizable, which means you can quickly adapt contracts and agreements for each customer. Additionally, you can pull customer data straight from your CRM database and add it to the agreement, saving precious time.

Flexibility is key when you’re trying to increase sales – and it is in this regard that PandaDoc shines especially brightly. The software lets you create interactive PDF files that allow customers to choose from multiple options, leave comments and questions, follow links, and more.

Pricing

If you’re looking for free digital signature software for PDF files, PandaDoc’s free eSign product is the best we know. It allows you to upload documents, distribute them to customers, and even collect payments as soon as the document is signed.

There are three paid plans.

PandaDoc Essentials ($19 per user each month) gives you access to document templates, the document editor, a quote creation tool, and analytic reports that tell you how much time users spend in your documents, the current document status, and more.

PandaDoc Business ($49 per user each month) is a digital signatures software plan that includes CRM integration, workflow automation, document customization, document library management, and Zapier integration.

PandaDoc Enterprise adds single sign-on, allows the creation of unlimited team workspaces, adds Salesforce integration, and provides data on individual user performance. Call the company for a custom quote.

Final thoughts

PandaDoc remains the top digital signature solution for sales organizations. It provides superb customizability, automation, and flexibility. Individual users should take a hard look at the free eSign program, which provides just about all the features you are likely to need for electronic document signing.

The next product in our quest for the best e-sign software is Formstack’s Sign. The company says Sign eliminates bottlenecks associated with other e-signature programs by fully automating the process within a robust, easy-to-use platform that reduces waiting time to a minimum. Sign is one of the few products that produce HIPAA-compliant e-signatures, which means you can use it to sign medical documents containing private patient data.

Features

Sign is ideal for companies dealing with highly sensitive data. Its electronic signatures meet both HIPAA and FDA requirements, making the program ideal when you need to sign a document online if the document is protected by government regulations.

As we have come to expect in our reviews of the industry’s best e-signature software, Sign relies on a simple yet effective drag-and-drop system for creating and customizing documents. This eliminates the need to call upon IT professionals for help when creating e-signing documents. You can easily mark the fill-in data fields that will be used to collect signatures, personal details, company data, and so on.

E-signature solutions aren’t worth much these days if they signers to be sitting at their PCs or laptops. We live in a mobile world. Formstack has responded by making Sign available on all platforms, including tablets and smartphones.

Like most of the best signature software solutions, Sign offers a variety of agreement templates for common contracts and other uses. You can customize the templates according to your company’s needs, of course. The Signs dashboard lets you set up reminders and alerts to ensure that your team stays on top of signature collection.

Formstack supports integration with more than 100 applications and services that businesses use on a daily basis. Integration with payment services like PayPal allows you to collect payments and send receipts with minimal effort. CRM integrations allow you to pull data from your customer relationship management system and incorporate the information in contracts and other agreements.

Electronic signature companies have a special obligation to ensure that all data transfers are protected. Formstack uses TLS/SSL encryption, PDF file password protection, and secured servers to guarantee that Sign documents and other data remain secure.

Sign allows parties to e-sign documents in person with mobile devices and tablets. You can also set up follow-up links where signers will be redirected after they finish signing a document.

Pricing

Formstack offers three pricing plans for Sign: Starter, Pro, and Enterprise. All three allow the creation of unlimited signatures, documents, and templates. Additionally, all three of these digital signature software online plans let you add a company logo, include audit trails and mobile signing, work with multiple file types, and set up automatic backups and storage.

Sign Starter ($20 per month for each user) includes all the features listed above.

Sign Pro ($32 per month for each user) includes SMS notifications, in-person signing, advanced branding, Gmail and Outlook integration, and more template options.

Sign Enterprise (contact the company for a quote) adds even more integrations plus custom data retention policies, API access, and HIPAA compliance.

Final thoughts

If you’re looking for the best electronic signature software, Formstack Sign is a solid choice. Top-class security, great automation features, and FDA/HIPAA compliance make Sign worth a look.

Docsketch promises 40% faster turnaround for signatures that are compliant with US and international laws. A free plan lets you create a digital signature quickly and easily. The affordable paid plans provide templates, reminders, and other useful features that streamline the signing process.

Features

While most PDF digital signature software solutions provide fancy, modern-looking interfaces, Docsketch chose a minimalistic look and feel. The design is refreshingly clear, and it makes using the service easy and enjoyable. All the options are easy to spot.

Both the free and paid versions of Docsketch come with full regulatory compliance and generate legally binding signatures. Docsketch e-signatures are compliant with UETA, ESIGN, and eIDAS acts. All the documents signed through the service are archived and protected from tampering, making them as legal as pen and paper documents.

The process of getting documents signed with this free online digital signature software is quite simple. Just upload your own document or choose one of the templates, then mark fields to be filled in with the signer’s signature and other information. After you’re done, just type the recipients’ email addresses. If there are more than one, add them in the order they’re supposed to sign.

Signers will be notified automatically when their turns arrive. The contracts, agreements, purchase orders, and other documents you create can be turned into templates for reuse, relieving you of the need to upload the same type of document multiple times.

Docsketch includes a variety of document tracking options. Like any candidate for the market’s best electronic signature app, Docsketch provides an audit trail that shows how and when people interacted with the document. You’ll be informed whenever one of your documents is viewed and signed. Documents like quotes and proposals that do not require a signature but do require approval can also be sent. Once recipients approve them, they’ll automatically receive the documents that require their signatures.

Documents sent through Docsketch can also include follow-up links after the document has been signed, and you can request attachments to be uploaded by the signer. As we’ve seen with some other digital signature software providers, you can also take e-signatures in-person through mobile phones and tablets.

Pricing

Docsketch has a free electronic signature plan and two paid subscriptions.

The free plan is for one sender only. It gives you access to one template and lets you send only three documents per month. It also lets you set up reminders and notifications.

The Personal plan ($8 per month) limits you to a single sender. You can send an unlimited number of documents, use five sample templates, and add links.

The priciest software for a digital signature plan – Docsketch Business – will set you back $24 per month for three users. You can add more senders for $8 per month each. In addition to everything included in the less expensive plans, you also get access to custom branding, attachment support, redirect URLs, unlimited template collection, and in-person signing.

Final thoughts

At first glance, Docsketch might seem barebones compared to other solutions. However, it has all the features you are likely to need in e-signature software, and it’s available at an affordable price.

Lightico provides a feature-rich suite of apps and services meant to improve your company’s workflow and overall efficiency. Among the many features of this comprehensive platform is electronic document signing. Lightico says its platform is ideal for companies in a broad range of industries: banking, auto finance, insurance, telecommunications, healthcare, law, and business process outsourcing. The platform is intended to boost efficiency, speeding up and automating every element of the agreement signing process – from document creation to signing and payment collection

Features

Lightico says documents created with its platform have the highest e-sign completion rate in the market. This is largely thanks to a simplified and streamlined process of collecting signatures. Lightico does not require signers to undergo lengthy sign-up processes or overly complicated identity-verification procedures.

Unlike most of the best e-sign software platforms, Lightico does not send email to let signers know that a document awaits their review and signature. Instead, it sends texts to recipients’ smartphones. This is often a more efficient way to notify customers, as they’ll see invitations immediately instead of wading through overflowing inboxes.

Once customers follow the link in the text message, they’re taken to a secure room where they can sign the document as easily as using a finger-swipe gesture. Once the document is signed, it becomes locked to prevent tampering. A time-stamped audit trail serves as proof of interaction.

Lightico e-signatures comply with ESIGN and UETA regulations.

One reason Lightico is widely considered to be one of the best e-sign service companies is that it makes e-signature collection easy. After a signer is shown how to sign a PDF document, subsequent signatures require only a tap to be placed on the document.

The ability to sign and review agreements through any device shouldn’t be underestimated either. One of Lightico’s standout features is its superb mobile optimization. All documents can be created, reviewed, and signed via mobile devices. Thanks to excellent optimization, you won’t have to squint your eyes while working with documents on the go. Lightico’s mobile-first approach positions the company well for the future.

This top e-signature software also supports a variety of CRMs and third-party applications, allowing you to add customer data to agreements and contracts with minimal fuss and bother. Lightico can also be integrated within websites and online shops, which is invaluable for e-commerce businesses.

E-signatures are not the only point of focus for Lightico. The platform’s services also encompass document creation, payment collection, identity verification, and much more.

Pricing

Lightico isn’t meant for individual users or small businesses. It’s tailored toward the needs of enterprises and large firms that need a robust document signing platform. In addition to providing legally binding e-signatures, it has a multitude of features geared toward streamlining sales processes and automating workflows.

Lightico discloses its prices only to potential customers. For an idea of what this platform will cost your company, you must set up a demo and consultation with the Lightico sales staff. They’ll want to know things like how many documents your company handles every month and how many members you have on your team.

Final thoughts

Lightico may not be tailored toward individual users or small teams, but it implements a huge number of useful features that are bound to help large companies save time and resources. It’s a worthwhile investment for large sales teams.

signNow is a piece of digital signature software used by millions, and it’s quite easy to tell why. It provides an intuitive interface that makes it easy to navigate through its numerous functionalities.

Features

The developers of signNow have truly created a uniquely great product. In addition to being feature-rich, it’s exceptionally easy to master. To top it all off, the signNow mobile apps for both Android and iOS phones enable you to access from anywhere.

Aside from being able to generate unlimited templates, you’ll also never have to worry about keeping track of all the changes in your documents as signNow does it for you. But to make it onto our Digital Signature Software comparison list, a program needs to have far more capabilities than that. In signNow’s case, there’s almost too much to cover in just a few sentences, but we’ll do our best.

You can send your signers customized reminders, and if you have foreign business partners, you can avoid any confusion or delays by allowing them to review documents in their native language. Another way in which signNow makes your business more efficient is by enabling you to send files to multiple recipients at once and to create separate teams for different projects.

This e-signature solution is great for any profession since it lets you add payment requests, create fields that appear only after a certain condition is met, ask for additional materials, and insert links directly into your documents.
Finally, we should mention that signNow is completely safe. With the second two plans, you’ll even get malicious threat scans and the option to set up an authentication method for your signers.

Pricing

signNow gives you four pricing plans to pick from: Business, Business Premium, Enterprise, and airSlate Business Cloud. They all cover the basic electronic document signing features that will help you run your business smoothly. You’ll be able to send your documents for signing to your recipients, from both the computer and the apps as well as have access to unlimited customizable templates, among other things.

The first difference between the plans becomes apparent when you need to collect the signatures – the Business plan limits you to one signer, whereas the other three allow 2+ signers. If you opt for the Business plan, you might experience another numeric limit that this software for digital signature input and collection imposes – you can only have one team. That’s not the case with the other three plans.

If you find yourself in need of customized documents that represent your business’s branding or forwarding documents to several signers simultaneously, you’ll have to abandon the idea of purchasing the Business plan and turn to the other three.

However, even the least costly plan, which is only $8 per month per user, has many features that will prove extremely useful. The pricier ones, of course, encompass even more distinctive features, most of which you won’t find with other digital signature services, such as redirect links, smart fields, SSO SAML authentication as well as integrations with NetSuite, Salesforce, Microsoft Dynamics, and countless other exceptionally useful applications. These pricing packages cost $15, $30, and $50 per month per user.

If you’re uncertain about using this platform, you’ll be happy to know that you won’t have to commit to a pricing plan right away. One of the many benefits of choosing signNow is that it offers a free trial of the Business Premium pricing plan, without requesting any payment information.

Final Thoughts

During our tests, we noticed a few kinks that could be improved. For instance, the templates were at times difficult to edit. However, among the currently available e-signature solutions on the market, signNow is definitely one of the best options you’ll find, especially if you run a large company. It simply makes dealing with multiple teams and heaps of documents considerably faster and easier, thus granting you more time to either focus on other aspects of your business or just sit back and relax for a bit. Once you try signNow, you won’t ever want to go back to the way you did things before.

DataProt’s Methodology

Finding the best digital signature software required us to identify and assess a number of key features. Each digital signature solution has a different niche and targets different users, but a small number of crucial metrics help us understand and compare them.

Authentication

Authentication is the process in which signers verify or prove their identity. When the e-signature process is initiated, software providers have different methods of authenticating identity. These methods include email verification, SMS verification, unique PINs or login credentials, biometric verification, even advanced methods like digital certificates, smart chips or ID cards, and more.

In digital signing software, authentication should not be confused with identification, which happens when a signer claims a certain identity by providing some sort of identifiable information and documentation.

The question of which authentication method is best for your company depends on the level of risk or confidentiality involved. For example, know your customer authentication, which usually requires data like the last four digits of a signer’s Social Security number, should be reserved for high-risk transactions. Email verification is fine in low-risk industries where the stakes are smaller.

Compliance

The best digital signature software should allow you to create and sign documents that are compliant with published standards. These can be document standards such as certificates of completion, watermarks, or signature disclosure.

Many businesses require legally binding documents. Digital signatures must comply with certain laws and regulations in order to be lawful and binding. In the European Union, the relevant statute is electronic identification and trust services, or eIDAS.

In the US, the regulations are found in UETA and ESIGN – the Uniform Electronic Transactions Act of 1999 and the ESign act of 2000. Japan, China, and other countries have their own protocols for digital signature regulation. That’s why we confirm that the digital signature creation software we review is compliant with these types of regulations.

Security and privacy

Digitally signed documents, their transmission and storage, and the signing process all may involve different kinds of sensitive information. The authentication process, for example, often requires that signers divulge some sort of personal information. Documents may include sensitive financial or company data – both of which must be protected with the utmost digital security measures. When properly implemented, digital signatures help maintain the integrity and authenticity of the document.

To meet that essential goal, digital signature signing software must implement advanced security features such as encryption, multi-approved privileges, the ability of parties to reveal information selectively, and confidentiality for the entire process.

Interface and notifications

One reason you sign documents online is that you want the process to be more time-effective than physical signing. Therefore, we expect digital signing solutions to include features that streamline the signing process for all parties involved. The online interface should clearly display the current signing workflow status, send reminders to people who did not yet sign, and notify users when a change in status occurs.

Other useful features implemented by the best e-sign software solutions include multi-signer documents; support for a wide variety of computing options, including mobile; and other quality-of-life features.

Pricing

One of the biggest drawbacks of traditional on-paper document signing is how costly it can be. It’s a time-consuming process that relies upon people and other resources that could be better used elsewhere. Physically transporting the signers or documents from office to office, especially over longer distances, can have direct financial costs.

Digital signing software is intended to reduce those costs, so the software mustn’t be more expensive than the traditional method.

Top electronic signature software solutions are usually SaaS implementations that are available by subscription, with monthly charges calculated based on the number of users. The least expensive subscriptions are usually limited to one user only, with additional fees when you send documents for other people to sign.
