Core SAP ERP is very flexible in terms of customization. There is no limitation for customizing modules with multiple options for creating dashboards. The UI can be improved but it's not that bad. I think there are some bugs which need to be fixed. This software was very helpful in our business and we were able to do all our accounting tasks in one place. It also helped us improve productivity and decrease manual effort. It's easy to use and has a lot of features, it also integrates well with other systems such as Salesforce. The customer support team is very helpful and knowledgeable. Nothing so far, I am using it for Manufacturing only. If you have multiple locations or users in different countries, this software can be used. For example if you work in the US and you need to make changes in Germany, it's easy to do that. With this software you can manage all aspects of your business.
