Perfect Software for Small Business I use this software for my home inspection business to create required insurance reports and include images. It allows me to upload the required insurance form, edit it and add images for the required mitigation and four-point inspection reports. I love that I am able to save my reports, reuse them by editing as needed and organize them in the straightforward filing system. Excellent value for all of the features offered. Easy to use and manage organization. Love the FAX feature, signature, editing and capacity to upload images. Flash feature for uploading images. Settings have to be set and sometimes reset themselves. I use this feature everytime and sometimes the software freezes.

I feel that it was inappropriate and a bit shady to let a customer edit the PDF and then hit them with the credit card ask. Maybe let them do a test for 15m or something.
