Erm, this is a salon forum, would you mind terribly talking in a language I can follow please!!!!
Am really interested in what you are both saying and debating but I am struggling to follow this thread. xx
OK, I'll try...
"SAAS - Software as a Service" - this means that the software runs on a server somewhere (usually via the Web) rather than directly on someone's PC - so things like Google Apps and Salesforce would examples of "software as a service". In the salon world, web based applications like Salonium, Appointment Diary, etc, are examples of salon software that follow the "Software as a Service" model. With these applications, your data (client details, appointment details, etc) is stored on a server in a data centre rather than on your computer.
Whereas the majority of salon software comes as a standard Windows application which is installed on your computer directly - and your client details, appointment details, etc, will be stored on your computer's hard drive.
Both approaches have their advantages and disadvantages. e.g. with "Software as a Service", you are relying on a third party to store your business critical data for you; if your Internet connection goes down then you can't access your client/appointment details, and if anything happens to the software provider's servers, or the company goes bust, then you'll probably lose all your data.
Likewise, with a traditional "standalone" salon software application that runs on your local PC, it's up to you to make sure that your data is backed up; if you don't make back-ups and your computer gets stolen or your hard drive fails, then you'll lose all your data.
As for importing/exporting data... the ability to do this is protection against "vendor lock-in". I can pretty much guarantee that most salon software will store data in a proprietary format which won't be easy to transfer to a different software package. Whereas it would be better if you were able to export data from a salon software system into a commonly used format (such as an Excel spreadsheet) - and likewise be able to import data into a salon software system from an Excel spreadsheet or whatever too.
