What accounting system should my company use?

We are a company that used to manufacture but now all we do is design and market. We outsource our actual manufacturing. Our sales are between 1-10 million annualy. We currently use ACCPAC Pro Series but I know their must be something better as this program is not very user friendly. We extensively use AP, AR, PO's, Sales Orders, Inventory, Multi Users, pre-payments, Payroll, Check Printing, Packing Lists and Report Printing.
