A VPN (Virtual Private Network) offers a way to securely connect to an Office network (LAN) remotely. Once the VPN connection is established, the user gets access to any network device on the network.
Basically a VPN allows people outside the office LAN to connect to the LAN and thus gain access to QuickBooks file or Tally (on a shared folder for instance). Any user connected using a VPN can then open QuickBooks/ Tally exactly the way they would do it at the office.
It sounds like the perfect solution, it is secure, centralized, does not require a computer per user at the office and does not require extra training to get started.
But the right VPN solution (Instant SSL Software VPN with inline data compression) and a decent Internet connection at the Office will offer a very good solution for accessing QuickBooks/ Tally remotely.
Setting up a VPN will also help Small Businesses introducing secure teleworking not just for QuickBooks/ Tally , but for accessing files, applications and devices remotely.
