Might be signing up again because of the combine pdf feature you offer. Adobe couldn’t even combine my pdfs for whatever reason. I would need a slightly cheaper subscription then you offer.

Professional look!
Got to know about PDFfiller because we use Salesforce at work, and these two are compatible. Taken together - tremendous time savings, at least several hours a week, i'd say!
Longer contracts might need a while to get fully visible on the screen, but no rush here

easy to upload signature
I really like the option of uploading my signature and saving it, and using it over and over again from within the system (something that Docusign does not allow).
