What would you do if you discover the contracts you used in running your online business were not legally binding?

Ninja Forms Digital Signature Add-On

Imagine if you or your client were in a courtroom, only for the judge to discover that the e signature used on the contract with your client (or customer) was not signed using a compliant UETA/ESIGN e signature application?

The legal and electronic signature industry is a highly regulated sector which has strict laws and regulations regarding the electronic signature and transmission process. This is especially true for legal contracts, invoices, time sheets and employee agreements that could end up in a court room.

Ninja Forms is a terrific WordPress Form Plugin! It is quite possibly one of the best ways to automate any number of tasks using a WordPress website (and of course their renowned forms plugin). However, signing legally binding contracts is NOT Ninja Forms primary focus (it is however ApproveMe’s WP E-Signature sole focus). We have invested many years building a system that adheres to the strictest UETA and ESIGN nationwide and foreign document signing regulations.

This Signature Plugin fills the gap between a WordPress Forms plugin and an esignature solution that is compliant with the UETA/ESIGN guidelines.

How this signature add-on is different from your average signature addon
The majority of WordPress contract plugins and digital signature add-ons out there are not legally binding much less UETA/ESIGN compliant (they fail to follow the countless laws and regulations guiding the document signing industry). These kinds of basic signature add-ons, only “record signature details when it is drawn, then they transmit this data to an online website server where the signature is converted and forever stored as a PNG (or JPEG) graphic file and finally saved on your own ftp server (forever).”

This approach exposes you and your client’s authorized signature on the ftp website server in which your WordPress website lives. The image file of your client’s hand written legal signature (the identical signature that is used to buy a house, sign up for credit cards, purchase a car, obtain a business loan) is accessible to ALL ftp intruders; placing both you and your signer at a potential risk of identity theft.

ApproveMe’s brand new signature add-on found at it is the connection point between a WordPress forms plugin and having a UETA / ESIGN compliant contract signing application that runs on your WordPress site.

Check out the video clip above to find out ways to save time and money by fully automating legal contracts for your website design, digital photography, freelance or consulting business making use of our Ninja Forms Digital Signature Add-On.


**ApproveMe’s Signature Add-On for Ninja Forms generates a UETA/ESIGN compliant court recognized contract with (optional) details/field values inserted anywhere you want them inserted in the contract. These dynamic field values are taken from the submitted form of your end user.

Your form submitter can either draw or type their legal signature using their mouse, trackpad, tablet or smartphone. All of this magic happens the instant an end user submits a Ninja Form by either emailing a signer specific invitation to their contract or immediately redirecting the end users.**

Another highly popular use case is pre-filling contract data that might change from contract to contract. Say for instance, you are a Web Design agency and you have a standard contract you send out that varies ever so slightly every time you bring on a new client. Maybe you have optional packages available that need to be noted in your contract. But creating a new contract from scratch is incredibly time consuming.

With this Ninja Forms Signature Add-On + ApproveMe’s WP E-Signature (business license) you can create a Ninja Form with the fields and sections of the contract that vary and add an additional field for the “Signers Name” + “Signers Email.”

Your Ninja Form would look something like:

DROPDOWN FIELD 1 = Dropdown of available packages
PARAGRAPH FIELD 2 = Classes or terms that vary from contract to contract

You would insert these Ninja Field values in your WP E-Signature contract in the proper places or paragraphs that pertain to this information.

You would choose the option “Email this contract whenever this form is submitted.”

Now, whenever you fill out this Ninja Form, your contract will be automatically generated with the custom terms from your Ninja Form submission and then a signer invitation email will be sent to the signer email address that was given in the Ninja Form submission.

Additional benefits of ApproveMe’s WP eSign Plugin and this for Ninja Forms Signature Add-On is that you are able to instantly create a legal contract for your clients to sign depending on their form information from a Ninja Form.

And that’s just the beginning. When a client signs…

… both you and the client will instantly get a PDF of the contract that they signed (eSignature automation at its finest).

…registering or sending your client to a third-party website to sign your legal contracts is not required (all signatures take place on your WordPress website… so the experience is on your site and not someone else’s)

… you’ll have a 100% legally compliant electronic signature on file to protect you AND the customer (according to UETA/ESIGN guidelines).

Ninja Forms Digital Signature add-on turns your WordPress site into a court recognized document signing application (but without the monthly fees… and with unlimited amount of users).

  • Ideal for anyone who wants to automate signature collection on proposals, quotes, timesheets, service terms agreements, new client legal contracts, waiver forms and much more! *

Immediately redirect your site visitors to sign a legally binding contract after submitting a WordPress Form that was created using Ninja Forms.

“I agree to terms” checkboxes have the legal standing of a limp handshake. Do the smart thing. Don’t get caught in a courtroom with a document that’s not legally binding.

WP E-Signature offers an incredibly in depth eSignature add-on collection with several easy to customize Ninja Forms eSignature automations and third-party integrations to even further improve your personalized document signing requirements.

The WordPress Online Contract platform operates on every leading PC and web browsers for smart phones. For example Chrome, FireFox, Opera, Safari, Android, iOS, and WebOS.

Besides being user friendly, ApproveMe’s Ninja Forms WordPress Signature Plugin is able to instantly enter details which was posted from a Ninja Form into a UETA/ESIGN compliant and courtroom accepted contract form utilizing your own WordPress website.

Therefore if you have a dropdown list of options in your Ninja Form named “Web Design Package” and you provide various products (different price points for each) it is possible to easily produce a legal contract which includes the package features of an order in the written agreement which is then sent to the end-user of your Ninja Form.

Instantly Trigger Contracts To Be Sent As soon as a client inputs data into and submits a Ninja form (that is connected to a WP E-Signature contract using this add-on) it is possible to instantly generate a Contract to be delivered either by email or by redirecting the signer to the contract immediately as the “thank you page.”

Connect Ninja Forms Digital Signature With WP eSignature This Ninja Forms Signature Add-On will blend the powerful automation attributes of Ninja forms with the eSignature features and peace of mind offered with WP eSignature.

Include Ninja Form Field Values Inside A WP E-Signature Contract With WP E-Signature’s Ninja Forms Electronic Signature Add-On, you are able to input submitted form information into a legal contract that is activated immediately as soon as a client submits a Ninja Form.

Redirect a User to a Electronic Signature Contract after Submitting a Ninja Form After a user successfully submits a Ninja Form they can be immediately be rerouted to the contract of your choosing by using this E Signature add-on.

Sends your Client a Contract Via Email Once they Complete a Ninja Form After correctly submitting the Ninja Form, there is the option to email the form submitter a contract (or perhaps a different customer if the additional customer’s email and name was in the recently completed Ninja form).

Signing Reminder Emails In the event that a customer has not yet electrically signed the contract which you were requesting them to sign after sending in your Ninja form, it is possible to instantly trigger signing reminder emails where you can choose the trigger date, the frequency of reminder emails, and the expiration date of the signing reminder emails.
