Many small and medium retailers, through their local pos vendors or pos resellers, choose to implement either a cash register or a pos software for managing their stores. Pos resellers usually install a software based pos system on each of the computer of these retailers. This means that there are as many installations as there are computers.The Pos reseller need to access each computer in order to set them up such as price list, customer, products creation. This is time consuming and imposes constraints on the deployment process.

Providing reliable and cost effective support to retailers can be too challenging and financially uninteresting. System upgrades and patches need to be applied on each single installation.

As there are as many installations as there are computers, the pos reseller need to access each computer to ascertain the nature of the problem faced by retailers. Is it a bug? Can it be a user error? Is it a hardware issue? Much time is often wasted to pinpoint the issue the retailer is experiencing and to close the error reported by the retailer

The accessibility provided by a asp based pos software is key. All the different stores and instances point towards a single database, which can be accessed at anytime and from anywhere, thanks to an Internet connection.

• No need to physically access each computer to deploy the solution. For example, pos hardware can be shipped directly to retailers' premises while the VAR is setting up the configuration for its customer. By the time the hardware reaches the customer, the system is already up and running
• Support can be provided remotely at anytime and from anywhere. The pos resellers can instantly discriminate between bugs, user errors, and configuration issues as well as pos hardware problems.
• Patches and upgrades need only be applied to the application server.
• It becomes interesting to tackle markets that used to be too remote or too small as the cost of providing efficient and timely support is kept to a minimum.
• Better, quicker and yet cheaper support is provided to retailers.
