PDF Contract Revision for e-Signature App

**Job title:** Update Contract PDF in Existing Electronic-Signature Application

I use an existing application that allows customers to complete and electronically sign a contract. After signing, the completed contract is automatically emailed back to me.

The application is functioning properly. I do not need it redesigned or rebuilt.

I only need someone to:

* Update the wording and terms in the existing contract PDF.
* Preserve all existing fillable fields and electronic-signature functions.
* Maintain the current professional formatting.
* Replace or update the contract within the existing application.
* Confirm that the signed contract is still emailed correctly.
* Test the completed process on both a computer and mobile phone.

I will provide the existing contract and the revised wording. The freelancer must make a backup before changing anything and must not modify any unrelated part of the application.

Please include details about your experience with fillable PDFs, electronic signatures, and updating documents within existing applications.
