Frequently Asked Questions
Common questions about Ninja Forms Signature Contract Add-On
With the Ninja Forms Signature Add-on by ApproveMe, along with a WP E-Signature license you can easily collect UETA/ESIGN compliant signatures from your visitors or website customers after they submit a Ninja Form on your website. You can even pass details from the submitted Ninja Form into your WordPress contract or document.
Yes, electronic digital signatures are legally binding in the United States and many countries around the world. United States in the US there are two digital signature Acts that established the legality of digital signatures in the US – the Electronic Signatures in Global and National Commerce Act (ESIGN, 2000) and the Uniform Electronic Transactions Act (UETA, 1999). Both the ESIGN and UETA establish that electronic records and signatures carry the same weight and legal effect as traditional paper documents and handwritten signatures, they say “A document or signature cannot be denied legal effect or enforceability solely because it is in electronic form.” The ApproveMe WP E-Signature plugin is UETA/ESIGN compliant. United Kingdom In the UK, similar legislation to the ESIGN Act in the USA was likewise settled in 2000, and is known as the UK Electronic Communication Act. European Union The appropriation of the European Directive 1999/93/EC of 13 December 1999 established a the utilization of electronic marks on electronic and digital contracts inside of the European Union (EU). Thirty European nations (EU-27, Croatia, Turkey and Liechtenstein) have officially adopted Directive 1999/93/EC. To that end Electronic and Digital marks are effectively being used in Europe, and ApproveMe’s compliant WP E-Signature plugin is legitimately acceptable and enforceable within the European Union. One of the best ways to ensure your document is EU compliant is to utilize our “Send Custom Contract Invitation via Email” feature. So when a user submits your Ninja Form they will be emailed a custom email invitation to sign their unique contract.

The Lifetime Plan does not have a renewal cost. It is a one-time payment for the WP e-signature plugin. However all other plans have an annual renewal. Our goal has always been to pull the price back as much as we possibly can so small businesses and freelancers could sign documents electronically using their WordPress website (and save alot of money in the process). Not only is our plugin the most powerful of its kind, it’s also the most affordable. Not to throw anyone under the bus, but look at what our competitors charge every single year: Adobe charges $1,080 / yr (per 3 users)
Not charing for renewals would actually hurt the product as we would not be able to invest as heavily as we currently do back into it...
Renewing your license provides an additional year of support and software updates. This provides peace of mind knowing you can turn to us for WP Electronic Signature related support and assistance. You’ll also continue receiving software updates to ensure WordPress compatibility (and security) as well as great new features and enhancements! Also (depending on your license) as we release new basic and premium add-ons you will be able download these at anytime.
Please feel free to contact us at anytime with any additional questions you might have at our contact form page.
