I have been using Quickbooks Enterprise for more that a year now in my brother-in-law's company here in Guam. As an accountant, it is always convenient to have a software to keep track on your records and not resort to the old style journal and ledger books.
My three and a half work experience in Orica Philippines exposed me to a high end ERP software like SAP. It is one of the great software specially designed for manufacturing/multinational company where operations is worldwide and synchronization is a must. The likes of SAP is the one that any big companies engage in a multifaceted operation; but for small and medium size organization I welcome you to Quickbooks.
Quickbooks is user-friendly. It doesn't require a lot of accounting knowledge and it is easy to learn. It has this graphical step by step process that will guide you in your business recording. From here on I will be dispensing all the knowledge and experiences I have gained as I use this software in my profession and work.
