The data file can grow to 1 gig or so, even bigger. The system may get slower as the file gets bigger. There really isn't a set datafile size. Premier will only allow 5 users to have access at the same time. You can have up to 10,000 customers.
Hope this helps. If so please mark solved, if not please ask more questions. Thanks!
