Working with a client recently, Drop a Stitch, we got to interface HostedStore with a product from Christian James, INC. PayGO. We were impressed. Having set up many Point of Sale systems on Macs this one totally stands out. I think one of the things that really enamored me was their, "open Sort of" model. the application itself is locked, but the database is open and all the data can be imported and exported with ease. Other systems we've done in the past included Big Business, and POSIM for a Mac Retailer. Because of the way this is set up we could immediately create a helper or transition file in FileMaker Pro that would talk to HostedStore and to PayGO.
