Does Everyone Need Access in Order to Fill a Form?

[Ashlyn2222]

Apologies if this has been asked before. I have created a fillable invoice form that will be sent to all of our clients via link in email to fill out and email back to me. It is my understanding that our clients then need to save this form as a copy to their computer in order to view and edit it to create their own invoice. The question/problem I am now facing - Do each of our customers have to have Adobe Acrobat Pro in order to fill out this form? Thanks in advance for any answers or guidance.

No.  They can fill it out and save it with Reader.

I'm having someone without Adobe Acrobat Pro test it for me, and it is showing Access Denied.

I'm assuming I'm not saving it correctly. Thank you for your response.

Can you upload the form?
