How to sign a contract online

Wondering how to sign a contract online? After the pandemic, digital resources such as those offered by Viafirma are an absolute must for companies that receive, send and sign stacks of documents on a daily basis and wish to automate their agreement process.

Let’s take a look at these benefits and how you can deploy eSignatures throughout your company.

Why should your company sign contracts online?

When it comes to online operations, removing barriers to completion is critical to growing the bottom line of a business.

eSignatures help automate you agreement process and also communicate a fresh and modern image to the market. Besides, customers are now more likely to choose companies that are able to offer easy-to-use, efficient solutions to handle operations from home.

Furthermore, new contracts to be signed and any subsequent addenda lead to stacks of paperwork, resulting in storage costs, risk of potential loss and wasting time and resources. These drawbacks can be solved with our signature solution for E-contracts.

Finally, our electronic contract solution helps you reduce your carbon footprint avoiding any unnecessary paper use.

Sign a fully legal contract online

Let us be clear: it is fully legal to sign a contract online, although people are still far too used to going to the company’s head office to sign on-site. So do not be afraid to sign or send a PDF for signature.

Viafirma complies with the the EU’s eIDAS act, the strictest European regulation in terms of electronic identification and trust services that regulates electronic signatures. We use 2 factor authentication, audit trails and OTP SMS to strengthen the level of security of the process. Furthermore, this is also the legal model for most countries in Latin America:

  • Data is uniquely linked to the signatory
  • it is capable of identifying the signatory
  • it is created using electronic signature creation data that the signatory can, with a high level of confidence, use under his sole control
  • it is linked to the data signed therewith in such a way that any subsequent change in the data is detectable.

 Besides, Article 25 stipulates that:

An electronic signature shall not be denied legal effect and admissibility as evidence in legal proceedings solely on the grounds that it is in an electronic form or that it does not meet the requirements for qualified electronic signatures.

For all these reasons, you can sign your contract electronically with full legal guarantees.

Also, E-contracts can be signed in person. Preparation of the documentation is similar to remote signing. The difference lies in the fact that both must be in the same place and it is the company that provides the signatory with a device that is capable of collecting a wealth of biometric data.
