I am creating an invoice which has fillable fields, such as time calculations for billing customers and I want to be able to have them sign it immediately after the employee inputs the start and stop time for the service. I would like to just walk through the the total time with the customer, have them initial start time, and when the job is finished, initial stop time and sign it. However, it seems like Adobe makes it excessively hard to accomplish this task as the form I have created has form fields which have formulas calculating total time and cost that will not work in Adobe Sign and Adobe Sign and Fill. The fields will not transfer with the equations I have inputted and it makes no sense to have the customer click 15 different buttons, sign with their finger or a stylus, and then try to re-size their signature correctly and try to drag it to the signature line on the form. Is there an easier way to accomplish this task that actually makes it worth it to the customer? What is the point of going paperless if it takes longer for them to sign a form than a piece of paper.
