The best thing is that I can use it for my business with ease! It's easy to install as well as configure in just few minutes without any technical knowledge required. There are no restrictions or limitations when you decide whether your customers should have access to their files stored within this software system only by selecting "Yes" (Allow) button after logging into My Account page. This product has been very helpful because we do not need much support from our side while using its services since they provide such advanced features which makes us feel comfortable about storing confidential information at one place. We store sensitive documents like invoices, purchase orders etc., so far there were minor issues but nothing serious enough to mention here. You don't really face an issue if you choose No Access option instead of Yes/No buttons available under each file type category i.e Invoice File Type.
