The app is very easy to use with its simplicity. I like that you can customize your view of different items in the inventory. Also, it's simple for small businesses without IT departments or employees who are used to technology. It isn't much more difficult than using an Excel spreadsheet. There also aren't many other features included as far as reports go which could be nice if they added them later. This has been beneficial because we don't have to spend time looking up data from another source such as our ERP system. I love that you can see your past income, expenses & balance at any time! The user interface is simple to use but there are many features not included in this free version (like recurring transactions). If it's simplicity of design or ease-of-use they did an amazing job with their software - very intuitive for both new users as well experienced ones like myself who have used other similar programs before purchasing another one from them later down the line when my needs change/grow again!?
