There are a lot of firms offering the software you probably need on an ASP-basis, with a shared database and access via Internet from wherever you are, payable on a variable fee (transactions done, Mb used, etc). No problems with programming, synchronizing data, software maintenance, new versions and the like, just use it.

One can't say much more without knowing both your country and your needs. Ask collegues or your business advisor or search google using terms as ASP CRM to start with. Lots of hits here, including sponsored links.

Good luck with your business.
