The trade service products of WTCCZ are non-profit, and the work principle is to balance the Revenue and expenditure.
All of the trade services provided by WTCCZ need pay your bills except some services specially marked to be used freely or just used for a try. The standard rate is based on the cost price of the service provided, and adds a normal service fee that is generally 10% to 15% of the cost price.
The staff of WTCCZ must explain the retails of rate, the standard rate and counting method to clients before they offer any service and then they can give the services after confirmation of clients. This way can make WTCCZ justice and equal.
This rate principle of breakeven business not only reflects the mission of WTCCZ, but also actually offers convenience and guarantee to those enterprises. This is the source of special commercial value of WTCCZ itself.
