POS system sourcing

One of Tokyo client is asking TW office to help on POS system vendor sourcing.

It is interesting to know there are two types of vendor providing service:

1. Standard type: fixed interface and minor additional modules , takes more steps to achieve a specific function // low cost(~150k TWD per year), quick implementation period
2. Project base: high customization level, fit to the needs. 10-fold more costs compare to standard type, takes 4~6 months complete the system implementation

It is important to consider a system that flexible and expandable in the future but also allocate the budget in an efficient way.

Although everyone know this simple key point, it is hard to see the roads and make a decision given unpredictable world, dilemma is everywhere.

Hope I can have a strong view ( I guess more mental part) on this topic in the near future.
