How To Build an eSignature Cloud Software With A Detailed Estimate

eSignature is the future of business that has already arrived. Now, any type of document could be signed electronically which directly influences all business spheres: from sales and human resources to customer and fintech services. Digital signature has the same legal weight as the handwritten one, and this means one of a kind technological revolution in business paperwork around the globe.

Let’s find out how digital signature services pave the way to new enterprise opportunities.

What is eSignature?

As more and more businesses are going digital these days, it is inevitable for documentation and paperwork to go the same way and eSignature comes in handy.

eSignature is the electronic counterpart of a handwritten signature. Basically, it helps sign documents online. eSignature solution serves three major purposes:

  • Authentication
  • Non-repudiation
  • Integrity

Thus, eSignature gives the signatory the reason to believe the document was created and sent by the claimed sender or that the document was not altered along the way (at any stage of the process). It also helps to electronically verify the identity of the signatory and the fact they give approval, consent, or confirmation to the information stated in the document.

This puts an end to time-consuming, slow paper-based business processes, and paves the way to new electronic document management, document lifecycle, and ecological paperless office.

How Does eSignature Software Work?

So how to create an electronic signature? The answer is obvious: via electronic signature software. eSignature software helps exchange legally sensitive electronic documents for the purpose of electronic signature collection.

Most of the digital signature services are built around the eSignature generator concept. Digital signature runs on asymmetric cryptography which means PKI (public key infrastructure) is involved.

When the sender creates the document with a digital signature, a mathematical algorithm generates a pair of keys: public and private. The sender keeps the private key while distributing the public key among the receivers (if there are more than one). Therefore, while electronically signing the document, the sender, with the help of an algorithm, generates data exclusively pertaining to the document, and then the data gets encrypted with a private key. This is also known as a cryptographic hash.

When the receiver gets the document, they decrypt the digital signature with the sender’s public key certificate. Then a cryptographic hash is again generated for the receiver.

Finally, both cryptographic hashes are compared to confirm the document’s authenticity. If they match, the document is considered genuine.

How Businesses Can Benefit From eSignature?

Electronic document signing brings extra value to almost any sphere of business enterprise:

  • sales departments
  • finance
  • customer service
  • human resources

eSignature makes it possible to sign sales contracts, invoices, offer letters, statements, non-disclosure agreements, and approvals without delays, and keep accurate audit logs for financial transactions. And what is more important, it helps reduce costs.

According to the electronic signature statistics, the implementation of eSignature in business resulted in:

  • 55% – 78.62% – total savings of businesses migrating to eSignature apps from paper, taking into account material, administration, shipping, and subscription costs.
  • 37 minutes vs. 5 days – traditional and eSignature time difference in obtaining signed documents.
  • 80% – average reductions in turnaround time using eSignature.
  • 80% – average error reduction.
  • 85%  – productivity improvement.
  • $20 – average savings per document.

To put it simply, eSignature means no more waste of time and money for businesses where every minute matters.

What Makes a Great Electronic Signature App?

It’s all about the value it brings to the business in general, and to a client in particular.

  • Platform compatibility

The app should smoothly run on any platform so the electronic paperwork could be signed without delays or issues. Ideally, this is what happens when you create a cloud solution for this purpose. Cloud solutions allow the software to run on any platform of the user’s choice.

Get Closer to Your Clients

  • Types of documents and formatting

It is important to place the right accents. What is the number of documents the business is working with? What are their formats? Should the app cover electronic signature pdf formats? Is there a need for electronic typed signatures? The more documents and formats the electronic signature app is able to handle, the better.

  • Features and customization

Yes, the set of features and their customization is crucial. Businesses look for solutions that would meet their needs. Templates editing, white labels, order of signing, drag-and-drop feature, CRM integrations – all of this influences the choice of the app. It is also important to understand that there must be the option of disabling some features.

  • Legal support

As long as eSignatures have as much legal power as handwritten ones, any eSignature app should consider the legal side of the fact that parties could sign documents online. Legal support for the software is crucial.

  • User-friendliness

User-friendliness is a must. If the software is bulky or difficult to use, this will most definitely influence business performance on many levels. From the speed of transactions to the loss of clients. User-friendliness adds up quite a lot to the business goals achievement.

Both “great” and “best” concerning eSignature software and apps are the variables. They work for their superlative meanings only when meeting the very concrete demands of a singular business.

Types of eSignature Explained

It is important to understand the types of eSignatures that best fit different business purposes.

There are three main categories of electronic signatures: simple, advanced, and qualified. The differences among the three are described by the electronic Identification, Authentication, and Trust Services regulation (eIDAS regulation) passed by the European Union (EU). This categorization is also applicable to the United States.

Simple Electronic Signatures (SES)

This is the simplest and broadest type of eSignatures. Mostly, they do not require identity verification and are used for documents with low liability risk. Since they have minimum legal weight compared to advanced and qualified electronic signatures, they are often used to sign internal documents, information letters, etc.

Advanced Electronic Signatures (AES)

Unlike simple electronic signatures, the advanced ones imply a higher level of user authentication. As the major purpose behind the AES is to identify the signatory and ensure there is no subsequent change of data (or that the change could be tracked), advanced electronic signatures require certification from a Certificate Authority (CA), and usually rely on public-key infrastructure (PKI) technology with the use of certificates and cryptographic keys.

Mortgage documents, rental agreements, non-disclosure agreement forms, etc. usually use the AES eSignature solution.

Qualified Electronic Signatures (QES)

In terms of legal weight, qualified electronic signatures are considered to be equivalent to handwritten signatures. This implies not only the fact that they are used for documents with high liability risk, but also that they should meet the strict and complex requirements for authentication.

Thus, in addition to identification measures characteristic of AES, QES demands prior authentication of the signatory, and the use of a qualified signature creation device (QSCD). QES are used to sign bank loans, consumer credit contracts, audit reports, etc.

Thus, the choice of eSignature type usually depends on the major type of paperwork the business handles.

What Are the Main eSignature Features?

A diverse set of eSignature features is used by millions of customers worldwide. However, it’s essential to keep in mind the main ones such as:

Document creator

This is an umbrella term for the number of features such as templates, drop-and-drag editor, preset blocks, white-labeling, branding, document builder, document themes, and supplemented documents. Most importantly, with document creators, remember that formatting is king. PDFs, Word documents, scanned papers, or faxes should all be easy to sign and distribute from any place in the world.

Filling out the form

The importance of the TX Text control feature could be hardly overestimated in this context. Textboxes, drop-downs, checkboxes, date fields – they should all run smoothly with this feature. TX Text control provides a comprehensive manner to fill out the forms within minutes. Data validation is also of great value. It helps avoid data entry errors and misprints and protects enterprise paperwork from “human error”.

Document management and analytics

Multiple workspaces, collaborative signing, bulk sending, order of signing, auto numbering, document forwarding, document analytics, responsive signing, offline access, real-time status let enterprises not only achieve their goals in a matter of a few minutes but also keep track of their paperwork and optimize document flow according to the obtained analytical reports.

Security

Document encryption and various types of identification are crucial. The more types of authentications, the lower the security risks. Thus, it is desirable to have email-based authentication, phone-based authentication, access code identification, ID verification, and third-party authentication. Password access and user access control are also essential. It is never too much when it comes to legally sensitive documents.

Extras

These features are usually created to serve a specific purpose. Let’s say to process payments initiated by digital signature as financial transactions. With payment features, debit or credit card info is collected and then processed via payment gateways. This not only makes business operations effective but also saves time and effort for all parties. With extras, there’s no limit to opportunities. The only thing to stick to is to know your needs.

Digital Signature As a Way to Secure the Cloud

It is no secret that more and more businesses today are moving towards data computing, placing their data, paperwork, and communications into the cloud. When everyone has access to the data they need in real-time, on the one hand, it accelerates business processes, while on the other hand, it raises the question of security.

So why is eSignature important for cloud safety?

  • Document security

eSignature is the means to protect the information and documents distributed around the cloud.

  • Electronic assurance of signed documents

Electronic signing assures authenticity, non-repudiation, and integrity, so business operations in the cloud could be conducted without worrying that data could be compromised at any stage of the process.

  • Ownership identification

eSignatures also help to identify the ownership and source of the message. This is important to prevent fraud, theft, enterprise espionage, and protect sensitive documents from cybercriminal activities.

Thus, one could say without any exaggeration that eSignature is vital to conducting business in the cloud service.
