Makes My Job Easy I use PDFfiller to create contracts and purchase orders. For contracts, I typically input data into Excel, and then use PDFfiller to create the finished contract from my Excel data. For purchase orders, I use PDFfiller to edit document information, highlight items, and sign the document. This saves me the hassle of having to print out documents, edit them by hand, and then scan/fax them. Very happy with PDFfiller, as it most certainly makes my job easier. PDFfiller has all the features that I need for my documents: adding a logo, highlighting, and drawing. I also think that it's great how you can seamlessly use Excel data to fill out forms automatically. This is especially helpful when creating contracts. The price is a little steep for what I see as somewhat of a basic software concept; however, it's worth it in my opinion. There is also a decent learning curve, but once you get the hang of all features, you can automate things and fill out your PDFs very quickly.
