webERP allows a dispersed business to operate an integrated ERP suite as an internet application. As a business expands its presence into different markets the challenge of communicating information to all the parties that need to know becomes progressively more difficult.
Combine the different locations where the business takes place with the growing number of staff who need access to the information and the problem compounds. Maybe the business wants staff to access at home on the road to add to the configuration problems.
Using the web this is all simple stuff - every computer or mobile device has a web-browser. Secure access over the Secure Sockets layer with https allows for the company's data to be encrypted and dual layer password access ensures that only those who have appropriate permission can access.
Irrespective of the cost of administering a VPN with dedicated fibre connections expensive servers and routers, perhaps a load balanced server farm running multiple instances of an operating system. With such complexity comes additional staff to manage, monitor and administer it and downtime sorting out the issues resulting from the complexity.
The simplicity of an entirely web-based system offers reliability as well as the complete side-stepping of all this complexity. Applying the fundamental rule of business KIS - "Keep it Simple" with various suffixes - web based wide area networking for distributed businesses is a "no brainer".
