We have built an online system that works just the way you work in the real world!
Printing companies generally have contractual (agreed) rates for every corporate customer they cater to. While placing an online print order, these rates need to be clearly displayed. The system contains a facility that displays those agreed rates whenever your corporate customer logs in to place orders.
Sometimes, a sudden or small print jobs comes up and the same needs to be treated on case-to-case basis. If you provide the system access to your corporate client, he can insert the rate or if you have disabled the feature, your customer will be able to view the rates without being able to modify them.
You can enter into any kind of agreement with your customer. because the system is truly flexible!
