Pros & Cons from Real Users Pros Very comprehensive set of APIs that allow the developer to create complex applications. The support has also been excellent. A very high quality SDK for all things PDF. As I understand it, it's based on the same code that Adobe products (e.g. Acrobat) use for PDFs, with some additions. That makes it essentially the reference SDK for PDF. The included support can be very helpful. Can be used with C#, Java, and C++. - It has one of the largest collections of PDFs. - There is a lot of variety for all the genres. - It has an easy and simple UI. Adobe PDF library is a nice and fancy tool. It has a lot of options and choices to choose from. Recommended. It makes it easy for managing documents. It offers files type conversion with a PDF reader. Very easy to use. Easy to create, edit documents and read large PDF files. Cons Because there are so many APIs, it takes a while to fully understand them and how they are used together. It's for-pay closed-source software. Has a bit of a learning curve to get started, at least when used with C++. Probably not a good match for very small projects. - The price of the software and PDFs is quite expensive. I liked the platform so far. I don't have any cons as such. It worked great for me. Nothing to share about cons.	Pros & Cons from Real Users Pros Easy to use. The workflow generation and application is intuitive and allows for a variety of process integrations. I like its ability to centralize and efficiently organize documents. It offers advanced encryption, access control and change tracking options, which ensures the confidentiality and integrity of information. In addition, its ability to automate workflows, perform advanced searches and generate detailed reports helps us optimize document management and improve operational efficiency in our company. For the most part, it is easy and intuitive to use. The online training is a huge bonus and has helped me figure out how to do many things. Square 9 offers powerful document capture and workflow automation tools. It's highly customizable and integrates well with other business systems. We are really enjoying using Global search to rid ourselves of paper files. We also use Global Search to automate the AR process for our online payments system. The document capture workflows are very easy to set up with no programming at all in a drag and drop web browser interface. The software is constantly being updated to add new features, including AI for smart document capture Cons Hosted environment is too pricey, but the on prem is perfect for us. One of the limitations I find is the lack of advanced customization options in the user interface. I would like more flexibility to tailor the look and feel and functionality of the platform to specific needs. Some of the nodes are a little complicated and the online training is not available. The user interface could be more modern and intuitive. Initial setup can be a bit complex for smaller teams. Although I do believe we get special pricing based on our organization which is non-profit, we can only afford a single CPU license for our on-prem setup for document processing which makes things a little slow. So depending on what volumes you need to process, you can get a backlog of documents in the capture cue waiting to be processed. In an ideal situation where funds are unlimited, we would likely utilize their cloud solution with additional CPU cores and also the AI add-on for more efficient document capture.
