Does what I need, the only thing is, it can be confusing when you try to log in, it takes you to another page instead of your actual account page so I have to search for something else to get to it, or I may just haven't located how yet, still good for what I need done.

As a landlord in a 2-family house, it's easy to create a lease. However, it's impossible to alter standard terms and conditions - this is a drawback.

I started the free trial, and my document has trouble being edited, so I hope this can be sorted. The help was quick and efficient and Kara escalated it when she knew there was a problem, so top marks there. I just hope the techie team can sort the font.

Document Signing and Editing Issues I just spent about an hour or so with Kara, one of your most helpful and patient online chat professionals. I was in the process of completing a contract and addendums where my Buyer was pressing me. I sent it out to my Seller and the Buyer once and ran into a number of editing and fillable field issues. So I recalled it. Kara took me step by step through each issue and patiently explained everything to me via zoom and screen share. She even went a step further and pointed out some features to me that will help me in the future. Even though I was a bit stressed in trying to get my documents completed, she calmed me down with her knowledge level and patience.I sure hope if I ever need pdfFiller's live chat support again, I'm lucky enough to get Kara again or someone with the same level of expertise. I enjoyed chatting and working with her.Joyce
