There are many vendor PDF forms that include a signature field but with no way to sign them just like the official W4 at this website. You can fill out everything digitally until you get to the signature field.

For our customers I hear the following solutions:

• Rebuild and maintain the form in Laserfiche Forms
  a lot of work and prone to mistakes, sometimes not permitted
• Accept without a signature and take the time to print and get a signature at some point
  time consuming, creates waste by printing to paper from digital and re-scanning to digital
• Use a 3rd party signature service
  time consuming, expensive, lacks direct automation at time of submission

Everyone we talk to about whichever of the 3 methods they use are unhappy with their process. Is there a better way?

I was recently shown a Forms product used by a municipality where you can upload one of these PDFs and it creates a form out of it (essentially just an image of the PDF as the background of the web form). Then instead of drag and dropping fields onto the canvas, they draw the fields directly over the image including the ability to add a digital signature field. In this way they can more easily update the form by dropping the new PDF in and just looking for anything that does not match up. They can still get all their metadata, build a business process after submission, and the form is signed when they view it in the repository.
